Re: problems with installing cygwin on windows 7

When installing cygwin using default option - everything goes well.

So I stopped it manually. I tried to do that using various download sites and it does not help. I am trying to install cygwin as a first package on freshly installed windows 7. Is anyone experiencing similar problems? What the remedy could be? Thanks in advance Piotr Hi Piotr, I have installed reinstalled Cygwin recently (and over the past 12 years). If you got the default version of Cygwin to install correctly, there is no problem with your computer, etc. A full install might take 12 hours, so be patient. Also, I have found that the kernel.org mirror is much faster than the anl.gov mirror I had previously used. A faster option might to use 2-3 steps: 1. Do a full download and save but don't install. 2. Do a basic (default) install from the saved files. This helps to verify that the download worked without any glitches (the connection from the mirror through the internet, your ISP, the Setup.exe program and your computer aren't perfect...sometimes things get garbled). 3. Do a few quick tests to see that the basic install worked (open a shell window and run ls -l, etc). Assuming that works, re-run Setup.exe and select a few more individual packages for a full install (maybe compilers, editors, etc). Even with just a few things, the postinstall scripts can still take a couple of hours to finish things off, so be prepared and don't kill them before they're finished. Repeat as necessary until everything you actually use is installed. If something goes wrong, you still have the saved download and don't need to repeat step #1. Just delete the c:/cygwin dir and start over at step 2. Enjoy! And thank you once again to the entire Cygwin team for helping those of us who are still stuck interacting with Windoze. ;) Alan Thompson P.S.

Re: Problems with permissions after installing cygwin without admin privileges
Hi - I'm not sure if this will help your problem, but in the past I have had to install Cygwin to a number of non-networked machines. For me, the easiest way was to use setup.exe with the option of save files but don't install. You can copy the saved folder and setup.exe onto a CD and take it to each installation target machine in turn. This eliminates any hassle with network permissions/visibility/latency during the install, which can save headaches. Since you seem to have gotten the first level of Cygwin installed over the network, this may not be your problem but it might be worth a try.

Re: Cygwin gvim needs weird ritual to past from Windows clipboard
On Wed, Jan 23, 2013 at 11:58 PM, Andy andymhanc...@gmail.com wrote: Guys, thanks for your replies. I might not have been clear enough in my original post, but the problem is in attempting to copy from a Windows app and pasting into Cygwin's gvim. Correct me if I'm wrong, but your responses (and the wiki site) are directed at copying from gvim to Windows. I'm pretty sure I tried Shift-Insert, and that didn't solve the problem. To be sure, the problem isn't *always* present, but it is usually present. When it is, nothing I've tried will fix it except the trick of highlighting arbitrary text in gvim before trying to copy something from a Windows app. About PC-based gvim, I also have that. But I tend to use the gvim text buffer as a bash command console, concocting bash code on the fly and either shelling out to generate/filter text or writing some lines to !bash. It's tricky to set up vimrc so that PC-based gvim can do this, though I think I've mostly got that problem solved. Just as vexing, however, is the constant need to convert the path to/from bash/cygwin posix form to Windows form. So when I need to bash around, I use the cygwin gvim. Everything I said works both ways, both Cygwin-Windoze and Windoze-Cygwin. The only difference in GVim is whether you use yank (Y) or put (P). This works for both the win32 version of GVim and the Cygwin X11 version of GVim. To be specific: - Highlight something in your browser and type Crtl-C - Go into GVim and type *P (i.e. double quote-asterisk-capital P). GVim sees the windows clipboard as a special buffer named * (i.e. asterisk, star, whatever). The double-quote references a buffer, star is the name of the buffer, and capital P means put contents here. Of course, both yank and put have both uppercase versions (whole lines) and lowercase versions (partial lines). Have you tried this?

Re: Cygwin gvim needs weird ritual to past from Windows clipboard
I always use the keyboard shortcuts to cut/paste from windows apps (e.g. Chrome/Firefox, etc). - Highlight the desired text (typically using v or V motion). - Copy using -*-Y (double quote, asterisk, y) to yank into the system clipboard - Paste into the windoze app (browser, etc) using Crtl-V as usual Also, note that for some things I use the Cygwin version of GVim (have to start the X11 server first), and for some things I use the native Windows version of GVim.

Re: ctags recursion broken?
Hi - As a long-time user of Cygwin and Exuberant ctags, it seems that the current version of ctags on Cygwin is broken. Specifically, /bin/ctags -R . /bin/ctags: skipping .: it is not a regular file. Normally, ctags should recursively descend and process all files from the current directory. I downloaded version 5.8 of Exuberant Ctags from http://ctags.sourceforge.net/ and it works as expected. Upon closer inspection, it appears that Cygwin has a different version of ctags (not Exuberant Ctags!) that does not support recursion at all! Specifically, ctags -V ctags (standalone 21.4.22) Copyright (C) 2007 Free Software Foundation, Inc. This program is distributed under the terms in ETAGS.README ctags --help Usage: ctags [options] [[regex-option ...] file-name] ... These are the options accepted by ctags. You may use unambiguous abbreviations for the long option names. A - as file name means read names from stdin (one per line). Absolute names are stored in the output file as they are. Relative ones are stored relative to the output file's directory. snip -R, --no-regex Don't create tags from regexps for the following files. snip So the -R no longer means recursion, and there is no --recurse option. Given that Exuberant Ctags is distributed under the GPL and is very powerful, it seems that it would be prudent to include it in Cygwin. I could even volunteer to be the package maintainer, if desired. How should we proceed?

I'm having a problem getting DLLs compiled with Cygwin to load into Sun JDK 1.4.1.

Here's an example. Take a simple Java Native Interface method like this:
$ cat jniTest.c
void Java_Test_test () { printf (test\n);}
And compile it like so:
gcc -shared -o jniTest.dll jniTest.c
Also needed is the Java-side file:
public class Test {
public native void test ();
public static void main (String args[]) {
Test test = new Test ();
System.out.println (loading jniTest);
System.loadLibrary (jniTest);
System.out.println (calling native method);
test.test ();
System.out.println (success);
}
}
Compiled it like so from a Cygwin terminal (replace /cygdrive/i/j2sdk1.4.1_02 as
appropriate):
$ /cygdrive/i/j2sdk1.4.1_02/bin/javac Test.java
Now run it, you should see it print loading jniTest, but nothing more.
$ CLASSPATH=. /cygdrive/i/j2sdk1.4.1_02/bin/java Test
In contrast, relink the DLL, but not using -mno-cygwin:
$ gcc -mno-cygwin -shared -o jniTest.dll jniTest.c
$ CLASSPATH=. /cygdrive/i/j2sdk1.4.1_02/bin/java Test
Now it should print:
loading jniTest
calling native method
test
success

you'll see that there it doesn't use -mno-cygwin. Here is the g++ task from the ant
build script:
property name=cppCompilerName value=g++ /
echo message=Compiling for Cygwin... /
exec executable=${cppCompilerName} dir=${ctmp}

Have you actually tried _not_ using -mno-cygwin?
Also, using 'javah' or not to generate the headers (and making sure JNIEXPORT and
JNICALL are in the header and implementation declarations, and using
and using -Wl,--add-stdcall-alias makes no difference. For this simple test case,
you need to have JNIEXPORT/JNICALL and the -Wl,--add-stdcall-alias, or neither to get
the test case to work.

Re: Linking with JNI Invoke Using Cygwin gcc
Hi Tom - There is a quirk when using the JNI Invocation API on Cygwin (non-invocation JNI works as expected). The solution is documented nicely at the excellent JNI-on-Cygwin webpage: http://www.inonit.com/cygwin/. You can also download some sample JNI code, including both invocation- and non-invocation-code at http://www.whitecaps.net/jni/expr.jar. Alan Thompson At 04:21 PM 6/5/2003 -0500, Thomas X.

Re: (Aucun objet)
Hi Jean-Luis, I also do a lot of java work on Cygwin. In addition to the answer Randall gave you, I would also encourage you to use the -classpath argument to the javac and java commands, rather than using the CLASSPATH environment variable. This provides a more solid control the classpath used for any given application and will help to avoid clashes between different java applications (which may expect different classpath's). I typically type the entire java -classpath XXX MyMainClass command into a short C-shell script so I don't need to re-type the command for repeated runs. Good luck!

Re: Fw: Please help. gcc 3.2.2 configure problem or what?
Hi - Look here (you probably already have): http://gcc.gnu.org/install/configure.html You are right, I used -program-suffix=-3.2.2. You need to be careful so that it finds only 3.2.2 files. Make sure you modify your path so that all of the 3.2.2 stuff is ahead of the normal stuff (both *.h files and libraries). Do a find /usr -name *3.2.2* -print to see all of the new files you need to be aware of. Once you set up this stuff in your build file (I have been using ant), gcc 3.2.2 works fine. I have been using it for JNI stuffno problems. Since I got this working, I haven't messed with the --prefix option.

Make the 3 files indicated, type go.csh, and it should work. This assumes you have
java (I use java 1.4.1) installed on your machine, and that the environment variable
JAVA_HOME is set to point to it (e.g. setenv JAVA_HOME c:/j2sdk1.4.1 or similar).
You should also checkout the excellent webpage on using JNI with Cygwin at:
