The import library libplplotf77cd.dll.a (to which is linked to) doesn't contain any symbols. If I change in plstubs.h STUB_LAU to #define FNAME(x,y) PLDLLIMPEXP y##_ #define FNAME_(x,y) y##_ it's still not possible to link to libplplotf77cd.dll.a (although it contains symbols of the correct name - but it's possible to link directly to libplplotf77cd.dll if I make changes to the files produced by cmake. So it seems that for MinGW 4.x.x the functions are also not exported by default (as with Visual C++) - I thought that this is now possible but not default (there is some visibility flag which can be set). Maybe someone has some additional ideas. Hi Werner, once I got it all working, I noticed the same thing: for some reason the import library (.dll.a) contains very few symbols. I have experimented a bit with STUB_LAU, but that has not solved much. The way forward is to write a small set of source files that mimick the set-up of PLplot - by then compiling/linking them manually I should be able to determine the correct incantation. But I come to the same conclusion: this version of GCC hides the symbols just like other Windows compilers. I am not sure I like that particular complication ;).

I assume, that if you install (official) MSYS you will be asked, where the MinGW directory is, and that you can use MSYS also with the unofficial MinGW package. Otherwise just open the Windows CLI and set the paths correctly. I wrote some lines about that in the wiki: http://www.miscdebris.net/plplot_wiki/index.php?title=Setup_mingw section Setup. If this doesn't work, or is unclear, let me know, since I want people to easily be able to follow the instructions. Hi Werner, I read that section - we should probably elaborate the text a bit: I was under the impression that this would give you a complete MinGW environment, but you do need to get Msys separately.

I have added the MinGW/bin directory to my PATH under Msys 3. which make gives that particular make.exe, so that seems to be fine (the compilers are also available) 4.

Also the file mingwvars.bat gets overwritten by the installer - with some syntax that was completely new to me (~dp0 IIRC to indicate the install directory). Under Msys the c:/mingw/bin syntax for the PATH does not work - you need to use /c/mingw/bin. It gives you a complete MinGW environment if you use the Windows CLI. MinGW provides all necessary libraries and headers and compilers and tools (except make) as windows executables. The compiler itself can be used from this point on, from the Windows CLI or some other IDE (e.g. CodeBlocks). MSYS is a minimal port of useful tools (bash, ls, automake, etc.) to use the MinGW tools within a unix-like environment to be able to use configure. The batch file I wrote was thought to be used within the Windows CLI not MSYS. The meaning of ~dp0 is e.g. explained here ( http://weblogs.asp.net/lorenh/archive/2006/03/24/441004.aspx ), and this is a Windows CLI command. Anyway, here is the situation right now: 1. I have installed the make utility from MinGW/TDM. Renamed mingw32-make.exe to make.exe Don't do that, since then you'll get into troubles with MSYS. MSYS provides its own make.exe and if you rename mingw32-make.exe to make.exe strange problems might occur using MSYS. If you're not using MSYS don't mind. CMake looks for mingw32-make.exe. 2. I have added the MinGW/bin directory to my PATH under Msys 3. which make gives that particular make.exe, so that seems to be fine (the compilers are also available) 4. CMake however complains that it can not find a proper build utility. If you are using CMake in MSYS it should look for bash.exe and maybe make.exe and gets confused, I don't know exactly. So it may be a problem due to the renaming of mingw32-make.exe. Anyways, if you want to stay with MSYS you don't need to install mingw32-make.exe anyway, so it's best to delete the files from the installation directory or reinstall the compiler tools. I will have to investigate this further - CMake worked perfectly under my old installation. I'll rewrite the wiki to distinguish if the user wants to use MSYS or Windows CLI. If you want to use MinGW in the windows CLI, you have to tell CMake to use the MinGW Makefiles generator, e.g. cmake -G MinGW Makefiles pathtosource HTH, Werner -- Dr. Werner Smekal Institut fuer Allgemeine Physik Technische Universitaet Wien Wiedner Hauptstr 8-10 A-1040 Wien Austria email: [EMAIL PROTECTED] web: http://www.iap.tuwien.ac.at/~smekal phone: +43-(0)1-58801-13463 (office) +43-(0)1-58801-13469 (laboratory) fax: +43-(0)1-58801-13499 - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Plplot-devel mailing list Plplot-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/plplot-devel

That library defines plsetopt7, but it may have the wrong underscoring convention or there may be some import/export of symbols problem. That library is mentioned in your detailed linking command above. Is the choice of library name and syntax of the command correct? gfortran also allows to change how many underscores are added ( http://gcc.gnu.org/onlinedocs/gcc-4.3.0/gfortran/Code-Gen-Options.html#Code-Gen-Options ) and in plstubs.h this can also be changed.

Can't find anything useful in the internet so far. For what it is worth, here are the equivalent results on my (Debian testing) computer: [EMAIL PROTECTED] nm bindings/f77/libplplotf77cd.so |grep plsetopt7 a1fc T plsetopt7_ [EMAIL PROTECTED] nm bindings/f77/libplplotf77d.so |grep plsetopt7 U plsetopt7_ That is pretty clear. The symbol that not defined internally by libplplotf77d is supplied by libplplotf77cd where it is defined. Here is your equivalent result. [EMAIL PROTECTED] grep plsetopt7 *.output libplplotf77cd.dll.nm.output:100049c3 T _plsetopt7_ libplplotf77d.dll.nm.output:100049c3 T _plsetopt7_ sfstubs.obj.nm.output: U _plsetopt7_ The U for sfstubs.obj seems correct, but I frankly don't understand the T for libplplotf77d since that symbol is not defined internally in that library. However, I assume the libplplotf77cd results means that symbol is really defined there so I don't see why there is a linking issue. The only possibility I can think of to explain the bad linking error messages for MinGW is the symbols are not exported correctly for libplplotf77cd or not imported correctly for libplplotf77c. So it may be worthwhile to look carefully at how import/export of symbols is set up for MinGW. For example, I notice there is no mention of MinGW in pldll.h. I assume #if defined(WIN32) works for MinGW, but there is a very special list of compilers to check in that case, and I am wondering if e.g., __GNUC__ is defined for your particular version of MinGW. Perhaps it would be more reliable (or at least understandable) to have a special stanza for MinGW as in the Cygwin case? Alan __ Alan W.

Re: [Plplot-devel] MinGW 4.3.1 fortran 77 troubles
Hi Arjen, Well, Fortran 95 is an (almost) strict superset of FORTRAN 77, so any F95 compiler should be able to handle F77 as well (*). The problem you encounter here most likely has to do with naming and calling conventions. I have never tried gfortran under MinGW (got g95 instead), but it is likely - in view of the use of DLLs - that the name in the object files should be [EMAIL PROTECTED] etc. Can you check what symbols you have in the libplplotf77d.dll DLL? (via nm or strings or whatever)? I attached the output of nm for libplplotd.dll and libplplotf77d.dll. I think that we should try to make plplot work for gfortran, since it's the standard fortran compiler of MinGW (g95 is not favoured by the MinGW guys for some reason) and it's very easily installed (e.g. http://www.miscdebris.net/plplot_wiki/index.php?title=Setup_mingw ). Hi Werner, from the nm output my guess is the trailing underscore is the problem. Well, this will require some experimentation. I will have a look at the gfortran/MinGW combination. I am fairly sure that a solution for the F77 bindings will also be a solution for the F90 bindings.

Do you have a Fortran compiler option you can use to get rid of the leading underscores? Also for the next iteration can you please use make VERBOSE=1 to get the full build commands being used? For deeper analysis of the problem (as opposed to my guess above) do you have a tool that is equivalent of the Linux nm application to figure out symbols that are defined in libraries? If so, I suggest you look at the symbols in the C library being linked to by libplplotf77d.dll to see what form of plsetopt7 is defined. I suspect you will find plsetopt7_ is defined rather than _plsetopt7_ . I have the same remarks for the fortran 95 case. Alan __ Alan W.
