cross compilation for windows from ubuntu

[bendanan]

Hi all,

I would like to cross compile VLC for windows 32 bits from Ubuntu 64 bits desktop and does not succeed using the following wiki:
http://wiki.videolan.org/Win32Compile

My Ubuntu desktop :
# uname -a
Linux pcneslog4 3.2.0-29-generic #46-Ubuntu SMP Fri Jul 27 17:03:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

I use the HostTriplet="i686-w64-mingw32"

I have installed:
sudo apt-get install git subversion cvs yasm cmake
sudo apt-get install gcc-mingw-w64 g++-mingw-w64
sudo apt-get install lua5.1 libtool automake autoconf autopoint make gettext zip p7zip nsis bzip2
sudo apt-get install g++
sudo apt-get install qt4-dev-tools

Everything is going well until the step "Building VLC".

I got the following errors:

AddFontMemResourceEx come from Gdi32.dll according to:
http://msdn.microsoft.com/en-us/library ... 85%29.aspx

It seams that the gdi32 lib is missing or is not found.

I can find it there:
# locate gdi32
/usr/i686-w64-mingw32/lib/libgdi32.a
/usr/x86_64-w64-mingw32/lib/libgdi32.a

I tried to add the gdi32 to libass in the configure.ac file:
if test "${SYS}" = "mingw32"; then
VLC_ADD_LIBS([libass],[-lgdi32])
fi

then bootstrap, configure and make, but still does not work

somebody can help me?

Thanks

[bendanan]

ok, no answer
Perhaps I didn't give enough informations?
or, this is not the right forum?

[bendanan]

To go further, I have disabled libass, which does not link here, with --disable-libass in the configure of VLC.
make
make package-win32

I got a binary.

When I launch vlc.exe -H, I got an exception 'unhandled vlc exception'.

Here is the log :

unhandled vlc exception

error while opening file

[nkoriyama]

I don't know why these references (AddFontMemResourceEx etc) are missing.
On my build environment, it works...

Anyway you can disable HarfBuzz when you build libass.
In contrib/src/ass/rules.mak, change "WITH_HARFBUZZ = 1" to "WITH_HARFBUZZ = 0".

[bendanan]

Thanks nkoriyama for your answer.
With this modification, the compilation and link of VLC seams perfect and goes to the end.
I still have the problem of vlc.exe -H which raises the same exception and error message but this time it goes much further. I don’t know if this can help, but here are the last output lines:
--sout-x264-psy, --no-sout-x264-psy

with the rest of the encoding options. Range 1 to 5.1 (10 to 51 is
also allowed). Set to 0 for letting x264 set level.
unhandled vlc exception
error while opening file

Apart from this error, when I open the preferences Window, all tabs are working but when I select the ‘Input / Codecs’ tab, the application exits. I don’t know if this is related.

Can you help me a little bit further?
What kind of information can I provide?

[bendanan]

Hi nkoriyama,

The compile problem of HARFBUZZ is only with the git version.
With stable version 2.0.3, this compile problem does not occurs, nor the -H option crash, nor the sound problem.

The git version has the following 2 problems:

1/ crash
--------
With the help of drmemory (http://code.google.com/p/drmemory), I found the crash problem of vlc -H.

contrib/win32/x264/x264.h define:
static const char * const x264_profile_names[] = { "baseline", "main", "high", "high10", "high422", "high444", 0 };
The last item is here 0. This is not the only case where a list is 0 terminated.

modules/codec/x264.c calls:
change_string_list( x264_profile_names, x264_profile_names )
which compute the size of the list with:
(size_t)(sizeof (list) / sizeof (char *))
Here the size of the list (p_item->list_count) is one more than needed because of the NULL item at the end of the x264_profile_names list.

src/config/help.c use for CONFIG_ITEM_STRING:
for( i = 0; i < p_item->list_count; i++ )
{
if( i ) strcat( psz_buffer, "," );
strcat( psz_buffer, p_item->list.psz );
}
The strcat fail for the last NULL item.

We have to add the following in the loop:
if( p_item->list.psz == NULL ) break;

For CONFIG_ITEM_INTEGER, it can be:
if( p_item->list_text == NULL ) break;

I will email a patch in the devel mail list.

2/ sound
--------
Still remains a problem with some video files for which Git version does not play any sound.
No sound is played for a file that I have and which use the codec:Windows Media Audio 2(WMA2).

[nkoriyama]

The compile problem of HARFBUZZ is only with the git version.
With stable version 2.0.3, this compile problem does not occurs, nor the -H option crash, nor the sound problem.

Because HarfBuzz doesn't exist on vlc-2.0.git.
Anyway I will see if the compilation fail will occur on Ubuntu.
At the moment, I build win32/64 build (VLC and contribs) with mingw-w64 on OS X, and I have no trouble.

[nkoriyama]

I tried to add the gdi32 to libass in the configure.ac file:
if test "${SYS}" = "mingw32"; then
VLC_ADD_LIBS([libass],[-lgdi32])
fi

On Ubuntu, I confirm that libass plugin cannot be built.

gdi32 and usp10 are required. And these libraries must be placed after harfbuzz in modules/codec/Makefile, like:

Code: Select all

LIBASS_LIBS = -L/home/nkoriyama/src/vlc/contrib/i686-w64-mingw32/lib -lass -lm -lharfbuzz -lgdi32 -lusp10 -lfontconfig -lxml2 -liconv -lfribidi -lfreetype -lz

If "-lgdi32 -lusp10" is before "-lharfbuzz", linking fails.

So, modify contrib/i686-w64-mingw32/lib/pkgconfig/harfbuzz.pc:

Code: Select all

Libs: -L${libdir} -lharfbuzz -lgdi32 -lusp10

I'll submit a patch later.

I have meet the same problem , have you solved this problem?

also i meet this problem:

Yes, your patch works.

[bendanan]

Hi bendanan

Hi dreamerZM,
Yes, it works. I don't have any problem with libpostproc.
It seams that the sources that are in the git repository don't compile from time to time ...
At least for me, the current sources don't compile with the following error:

Code: Select all

../../../extras/package/win32/../../../modules/codec/avcodec/dxva2.c:80:20: fatal error: dxva.h: No such file or directory compilation terminated. make[4]: *** [libavcodec_plugin_la-dxva2.lo] Error 1 make[4]: Leaving directory ` ... /win64/modules/codec'

This compil error is *before* libpostproc, but going in modules/video_filter, and doing make, libpostproc compile.
Sorry to not being more helpful

[bendanan]

the following patch works for me:

Code: Select all

diff --git a/modules/codec/avcodec/dxva2.c b/modules/codec/avcodec/dxva2.c index b22b248..178f5a2 100644 --- a/modules/codec/avcodec/dxva2.c +++ b/modules/codec/avcodec/dxva2.c @@ -76,8 +76,6 @@ # undef MS_GUID # define MS_GUID DEFINE_GUID /* dxva2api.h fails to declare those, redefine as static */ # define DXVA2_E_NEW_VIDEO_DEVICE MAKE_HRESULT(1, 4, 4097) -# else -# include <dxva.h> # endif #endif /* __MINGW32__ */

[JohnPeterson]

The file was added 2012-06-28 svn log https://mingw-w64.svn.sourceforge.net/svnroot/mingw-w64 -v --diff -r5149|colordiff to match the Windows header names.

The latest .deb are too old.

But it only has content that dxva2api.h had previously, an empty dxva.h will therefore suffice touch /usr/i686-w64-mingw32/include/dxva.h.

[bendanan]

Thanks a lot.
It's working
