Re: [Help-glpk] The dynamic link library for GLPK for Java could not beloaded.
Dear Onor, the Java system parameter java.library.path defines the directories that are searched for native libraries. java.library.path should point to the directory where you have stored Linux: libglpk_java.so Windows: glpk_4_45_java.dll On Linux this path typically is /usr/local/lib/jni, or /usr/lib/jni. For example you could call your Java class like this: java -Djava.library.path=/usr/local/lib/jni MyClass If you start your program from Netbeans or Eclipse, you can save the parameter value in the project properties.

Re: [Help-glpk] java glpk 4.45 for linux
Hello Ramón, GLPK for Java is hosted at http://glpk-java.sourceforge.net/ For Ubuntu and Debian there is a package libglpk-java. For Windows GLPK for Java is contained in the GLPK for Windows available at http://winglpk.sourceforge.net/ A GLPK for Java application consist of - the Java application libary - the GLPK for Java class library (e.g. glpk-java.jar) - the GLPK for Java JNI library (e.g. libglpk_java.so) - the GLPK library (e.g. libglpk.so) See glpk-java-1.0.16/doc/glpk-java.pdf for details If you want to deploy a web application which executes GLPK on the client, you must provide the binary libraries to the client, which match the client operating system and processor architecture. As client can be very diverse, e.g. 32bit and 64bit, and operating systems including Windows, Linux, OS X, NetBSD, deploying the binary libraries can be challenging. glpk-java.jar itself does not depend on the operating system and processor architecture. Alternatively you could deploy a web application which calls a Java written webservice on your server. The challenge here will be that the GLPK library is not threadsafe.

Consider using java -Djava.library.path= The current value of system property java.library.path is: C:UsersMarksworkspaceTERlibrairiesjdom;C:UsersMarksworkspaceTERlibrairiesglpkw64 I believe JDOM is working otherwise the compilation would tell it, but I cant figure how to make GLPK work again, Ive tried everything.

Re: [Help-glpk] Some question about installing GLPK for Java in Linux
Dear all , now I change the java version to sun-version java version 1.6.0_33 Java(TM) SE Runtime Environment (build 1.6.0_33-b03) Java HotSpot(TM) 64-Bit Server VM (build 20.8-b03, mixed mode) and tried to re-installed libglpk-java. But when I setuped configure , it occured that checking jni.h usability... no checking jni.h presence... no checking for jni.h... no Where does this file should be ? I check in my java folder /usr/java/jdk1.6.0_33/include . It has this file and my JAVA_HOME also setuped this path. Do I miss something here? Or I made other stupid mistake? Thank you!

Re: [Help-glpk] glpk java
Hello Fabrizio, a package libglpk-java is available for Ubuntu lucid, unfortunately it is the glpk-java 1.0.1 version. When I compile glpk-java on Debian Squeeze jni.h is taken from: /usr/lib/gcc/i486-linux-gnu/4.4/include/jni.h This file is included in package libgcj10-dev which is part of package java-gcj-compat-dev. Hence I suggest you install the following packages: sudo apt-get install java-gcj-compat-dev sudo apt-get install swig sudo apt-get install libtool With these packages installed glpk-java should compile without changes to the Makefile.

[Help-glpk] GLPK-Java JNI in Mac OS X 10.5.8
Dear all, I've some problems while testing the glpk-java for MacOS X 10.5.8. I'm working with GLPK-4.47 and libglpk-java-1.0.19. I've downloaded the latter and properly compile it for x86_64, to avoid the 'match-o, but wrong architecture' error issue. Now, the library is compiled for 64 bits, and seems to be no problem when being loaded by Java VM. The problem arises me when I try to invoke GLPK from Java: Exception in thread AWT-EventQueue-0 java.lang.UnsatisfiedLinkError: org.gnu.glpk.GLPKJNI.glp_create_prob()J at org.gnu.glpk.GLPKJNI.glp_create_prob(Native Method) at org.gnu.glpk.GLPK.glp_create_prob(GLPK.java:65) at net.sf.javailp.SolverGLPK.solve(SolverGLPK.java:115) (...) It seems such a method is not defined in the JAR file, but I'm using the glpk-java.jar and the JNI dynamic library, recently compiled from libglpk-java-1.0.19 sources. Am I missing something? Any idea? It's a pity that the tool I've developed is unavailable to run on MacOS by this error :'(, it would be wonderful if you guys have some idea to fix this!

I've messed with many things in my .bashrc and in the script that starts up the java program, to no avail. My only current thought is that there is a version issue: the program I'm using was written using glpk version 4.47, whereas I installed 4.52. Is there no method called init_glpk() in version 4.52? Or is there any other hint any of you might have? Thanks in advance for any suggestions! Jeremy -- *___Jeremy M.

Re: [Help-glpk] NoSuchMethodError
Hello Jeremy, Exception in thread AWT-EventQueue-0 java.lang.NoSuchMethodError: org.gnu.glpk.GLPK.init_glpk() You cut of the call stack from the output. Please, analyze the call stack to identify the calling method. GLPK 4.47 and the matching GLPK for Java 1.0.18 did not have any method init_glpk(). Could this be a method that once was a part of your user code? The current version of GLPK is 4.55. The current version of GLPK for Java is 1.1.0. Ubuntu Vivid (= 15.04) provides packages libglpk-java (1.0.37) and libglpk36 (4.55-1). I suggest you start by cleaning up your system. Remove your outdated local GLPK and GLPK for Java installations. Probably the relevant files are in /usr/local/bin /usr/local/include /usr/local/lib /usr/local/lib/jni /usr/local/share/java After cleaning up either install the appropriate Ubuntu packages or you download glpk-4.55 and GLPK for Java 1.1.0 and build and install from source.

My only current thought is that there is a version issue: the program I'm using was written using glpk version 4.47, whereas I installed 4.52. Is there no method called init_glpk() in version 4.52?

[Help-glpk] glpk4.38 or later for Java
Hello all, Is there a jar file available for recent versions (glpk 4.38 or later) for java? The only one I could find on the net was glpk 4.8 ( http://bjoern.dapnet.de/glpk/). However, glpk 4.8 has different interpretation in at least lpx_set_col_kind and lpx_load_matrix. lpx_set_col_kind keeps giving the error lpx_set_col_kind: not a MIP problem whenever I set a variable lp.setColKind(colIndex, LPX_CV). Since the above call isn't mandatory, the code works fine even after removing it. On the other hand, lpx_load_matrix or lp.loadMatrix() for java keeps giving the error that zero element is not allowed. ( My code works fine for C++, glpk 4.38 and I need to convert it to java for an application).

[Help-glpk] Viewing input constraints in Java
Hello, I am using glpk-java to solve a network flow LP using the simplex solver (smcp). The solver has solved a few instances correctly, but not all (even simple ones). My belief is that one of the constraints I am building is not getting input correctly. The problem is, I do not know how to view a constraint in Java after it is built. I know the function glp_get_mat_row returns the number of variables in row i, as well as stores which variables and coefficients in ind and val. The problem is that in Java there is no way to access the individual indices of SWIGTYPE_p_int or SWIGTYPE_p_double that I can find.

[Help-glpk] Getting null object when using read_model()
Hello all, I am an intermediate Java programmer and am using glpk-java too import a model written in MathProg and run it inside of a Java GUI application. The model runs just fine if tested in GUSEK, but when I try to create an object of the model in java using the read_model(.modFile, data, output) method, I get a nullpointer exception because the object being created is null. The model imports multiple .csv files to use as data sources, but no .dat files, thus the second parameter in the read_model method is null. Is there an issue with glpk-java creating an object from a model that imports .csv files? How can I work around this? Thanks so much for all of your help.

Hello all, I would like to know if there are folks happy with the libglpk-java llibrary binding. I am now going through java system calls to C, with the C code calling the libglpk C library. The interface is via input and output files, which has worked very well, but I am looking for a full java solution (to avoid the file read/write). On linux CentOS, libglpk-java has been unreliable. For the same problem, I get the right solution at times, a glp_error_hook error message at times, and no exception handling message at all at other times.

Re: [Help-glpk] Patch for GLPK 4.35 to support SWIG
Hello, When I generate a java interface for GLPK, I typically do something like this: mkdir -p java/org/gnu/glpk swig -java -package org.gnu.glpk -o src/glpk_wrap.c -outdir java/org/gnu/glpk glpk.i so as not to clutter up the root of the source tree. Then, i'll jar up the contents of the java directory into glpk.jar, and use my IDE (XCode) to compile the GLPK sources along with the generated src/glpk_wrap.c into a shared library (obviously, in order to make the compile work, the code should be linked against the jvm and contain jni.h and jni_md.h in the includes path). I should note that SWIG doesn't generate a particularly pretty java interface for GLPK -- but it does generate an interface that works. I have written my own java adapter classes that wrap the java code that SWIG generates to make it much more programmer-friendly. I can share them if anyone is interested. --Kelly --- On Thu, 1/29/09, xypron xypron.g...@gmx.de wrote: From: xypron xypron.g...@gmx.de Subject: Re: [Help-glpk] Patch for GLPK 4.35 to support SWIG To: Help-glpk@gnu.org Date: Thursday, January 29, 2009, 4:18 PM Hello Kelly, Today, I went ahead and packaged them into a patch file so that (hopefully) they can make it into the trunk and save me the effort of maintaining my own local GLPK copy. I appreciate you patch. GLPK compiles fine with the double definitions removed from include/glpk.h. I would propose to put glpk.i into a new directory swig/ because when calling swig -java glpk.i a lot of new files will be created in the same directory as glpk.i.

Re: [Help-glpk] Reenterable patch for GLPK-4.47
Thank you. However, do you mean reenterability or thread-safety? These issues are often mixed up. And another question: in your opinion, how one could use a reenterable (or thread-safe) version of glpk? I mean reenterability. I can tell why I desire reenterant GLPK in my application. My application searches for optimal parameters for thermocompensated Crystal oscillators. After mesurement of 64 oscillators, I need to launch a separate medium-size optimization task for each of them. Initially I launched them as separate OS processes, it was not convinient. My application is written in Java. I bind GLPK to java with glue interface based on JNA. http://en.wikipedia.org/wiki/Java_Native_Access Java has nice concurrent framework I want to use it. I want to launch optimization tasks (glp_probs) in different Java Threads. No synchronization is necessary, because tasks don't interact with each other. Solution with thread-local GLPK environment helped me to run GLPK tasks in different Java Threads. Thank you for providing glpenv02.c ! However, there was an issue. Java usually don't require to free unused objects. They are gathered by garbage-collector. Java runtime executes object's method finalize before erasing unused object, Method finalize of my Java wrapper of glp_prob was implemented as glp_delete_prob. Garbage collector may run in a separate thread. Thread-local GLPK signalled error when a glp_problem was allocated in one thread, and then it was freed in another thread by garbage collector. I had to insert explicit glp_delete_prob in the end of each task. I know that this is usual style in C, but this is aside of Java style. I think that it would be nice if ENV structure was not thread-local but instead it was a part of glp_prob. However, this change breaks existing API. So now I'm not sure what is the best patch. As to patches, I see three ways: i) post them to the help-glpk mailing list as a gzipped attachment, providing necessary information in the message body and a subject line suitable for the search; ii) add a topic to http://en.wikibooks.org/wiki/GLPK and include the patches there; iii) officially glpk is hosted on GNU Savannah; see http://savannah.gnu.org/projects/glpk (though currently I don't use this service). I could add you to the project member list, so you could upload patches to the project repository. As a first step, I put a new section into the Wikibook. It collects information scattered in the mail list. http://en.wikibooks.org/wiki/GLPK/Using_the_GLPK_callable_library#Reenterability ___ Help-glpk mailing list Help-glpk@gnu.org https://lists.gnu.org/mailman/listinfo/help-glpk

Hello Ricardo, on a 64bit system you could install two different Java runtimes: A 32bit runtime and a 64bit runtime. A 64bit runtime can only load 64bit libraries. A 32bit runtime can only load 32bit libraries. Did you check the bitness of the GLPK library (glpk.dylib)? The glpk_java.dylib will load glpk.dylib. The bitness must match. For the bitness of GCC.

Re: [Help-glpk] Patch for GLPK 4.35 to support SWIG

I have written my own java adapter classes that wrap the java code that SWIG generates to make it much more programmer-friendly. This is, regrettably, not specific to the java interface generator in SWIG but can be said about basically any language binding it creates. The Perl bindings for GLPK work quite similarly to the way you describe: a low-level SWIG-generated binding is wrapped inside a nice perlish interface class with some convenience functions. I too second the inclusion of the glpk.i into the GLPK source tree. Best regards, rg0now ___ Help-glpk mailing list Help-glpk@gnu.org http://lists.gnu.org/mailman/listinfo/help-glpk
[Help-glpk] Java interface to GLPK - accessing result values
Hi all, I plan to use GLPK by a Java application. I'm happy about the SWIG-based Java API - many thanks to Xypron. My application will use a predefined (MIP) model but dynamically created data. There are several possibilities to feed the data to the problem object, so far so good. (For sake of simplicity I use a data file in my example, too.). My question is about the step after solving the model. I want to further use the result values (values of decision variables after successful model solve) in my Java application. I created a solution which avoids files and databases. I would like to know how you experts look to this approach, and would appreciate any suggestions and improvements. I have no idea if it is trivial, stupid or the intended way to do this. I also have no idea if there are pitfalls regarding memory usage, efficiency etc. Thank you in advance!

Re: [Help-glpk] ANNOUNCEMENT: OptimJ solver link for GLPK/Java
Larry, Curious. Why is OptimJ released under a commercial license? It is based on Java, can be use as an Eclipse plug-in, and uses a number of free software or open source solvers. Nothing curious: the OptimJ language is based on Java, in the sense that if you know Java you'll learn and master quickly the optimization-specific features. But these are two different languages, using different compilers and different Eclipse plugins. In short, we designed and wrote the OptimJ compiler and tools from scratch. Commercial plugins are commonplace for Eclipse, and commercial modeling languages are commonplace for open source solvers. Is Optimj contributing back to the free software community? Yes, when it is compatible with our business model and the need to feed our families. See for instance the OptimJ GUI (graphical user interface, soon available also for GLPK). I don't mean to call you out on this just wondering why. You're welcome, this is a sensible question. -Patrick ___ Help-glpk mailing list Help-glpk@gnu.org http://lists.gnu.org/mailman/listinfo/help-glpk

OptimJ is free in the monetary sense (no money changes hands) but not free in the sense of the FSF. Allow me to precise that OptimJ is a source-to-source generator (it takes high-level modeling code and generates Java source code) that does not link In this case, IIRC, the source code as defined by the GPL would not be the java, it would be the input to OptimJ. to any optimization library including glpk.
