There is a problem for using Cygwin as a compilation environment for VLC, FFmpeg, x264 etc. with the latest version of packages (at least since 7 oct. 2006).

VLC (svn 16959 but also later revisions) compile breaks at:

Code: Select all

misc/version.c:6: error: missing terminating " character
misc/version.c:7: error: missing terminating " character
misc/version.c:7: error: parse error at end of input
make[4]: *** [misc/libvlc_a-version.o] Error 1

The contents of version.c (generated every compile by ./toolbox --update-version) appears flawed and shows the svn version nr. with a question mark "16959?"

Using a simple svnversion test the following output is created:

Code: Select all

$ bash --version
GNU bash, version 3.1.17(9)-release (i686-pc-cygwin)
Copyright (C) 2005 Free Software Foundation, Inc.

$ test=`svnversion .`; echo \"$test\"
"16959

This is wrong since there is a missing " at the end. Reverting to older bash 3.1.17(6) does show a " at the end but still the version.c has the same problem with the question mark. This doesn't only affect VLC but also other sources such as x264 (svn 584) compilation:

Code: Select all

In file included from x264.c:42:
config.h:5: error: missing terminating " character
x264.c: In function `Help':
x264.c:142: error: missing terminating " character
x264.c:142: error: parse error before ',' token
make: *** [x264.o] Error 1

Again the version nr. inside the generated config.h is not correct and shows a ? mark at the end. FFmpeg (svn 6572) already fails on configure:

Code: Select all

$ ./configure
: command not found:
: No such file or directoryull
'/configure: line 20: syntax error near unexpected token `{
'/configure: line 20: `show_help(){

The problem seems bash / dos2unix related.

The advice for now is if you have a working environment, DO NOT UPGRADE any package at this time. If you have any suggestions please post here. Downgrading binutils, bash etc. does not help.

Some threads referring to broken cygwin/binutils/gdb:

I have had a similar problem while compiling 0.8.5 with cygwin.

By changing some stuff I got it to work again.

The solution I had found was that your keyboard language should be set to 'United States(International)' which fixed the problem for us.

Besides that, uninstall SVN and download the source of vlc manually.

This fixed my problems trying to compile under cygwin.

Hi,

I'm new using VLC and tried to compile it from SVN using cygwin. I ran in this problem to. I fixed it by patching the toolbox script.

Actually svnversion seems to append a M$ carridge return after the version number. this code seems to correct the problem:

toolbox 'Create version file' line 608

Code: Select all

VLC_CHANGESET=$(echo $VLC_CHANGESET| tr -d '\r\032')

Hope it helps.

Regards,
Frederic

So, can anybody tell me, what version from SVN (rev. 15380 or higher) is most stable and easy to compiling with cygwin? I try to build rev. 15380 with precompiled libraries contrib-20060428-win32-bin-gcc-3.4.5-only.tar.bz2, it's compiled almost normally, but executable file not works perfectly - telnet interface starting is impossible.

Any ideas? Anybody can help me? Thanks a lot.
PS. Excuse me for my bad English.

I've added a new howto to the wiki which should cover the existing problems with Cygwin and work with latest svn again: http://wiki.videolan.org/Win32CompileCygwin

Yes, it works.

Now I can build rev. 18730 from SVN using contrib-20061202-win32-bin-gcc-3.4.5-only.tar.bz2 precompiled libraries. But a lot of warninigs on configuring (about 10) and compiling (more than 1500) still present.

Is it normal? How I can fix this problem? Thanks a lot.

Warnings are just warnings, not error . So if it compiles, then it is OK.

This works for me as well, nice page for those running Windows!
