Running this on Raspberry Pi / Debian / Wheezy about ffmpeg-windows-build-helpers HOT 14 CLOSED

So you used this to cross compile for windows, from a raspberry pi, or were
you cross compiling for raspberry pi?

Worked pretty nice.

For libxavs I had to add the "--disable-asm" option to configure.

build_libxavs() {
do_svn_checkout https://xavs.svn.sourceforge.net/svnroot/xavs/trunk xavs
cd xavs
export LDFLAGS='-lm'
generic_configure "--disable-asm" # unfortunately this using --host isn't
enough apparently...
unset LDFLAGS
do_make_install "CC=$(echo $cross_prefix)gcc AR=$(echo $cross_prefix)ar
PREFIX=$mingw_w64_x86_64_prefix RANLIB=$(echo $cross_prefix)ranlib
STRIP=$(echo $cross-prefix)strip"
cd ..
}

Hello Roger,

indeed I was cross compiling for windows on my RaspberryPi,
because i have no access to any other Intel linux machine
right now.

Your cross-helpers work pretty good. I appreciate this.

Cross compiling with bootstrapping the cross-compiler, which
also flawlessly worked, took about 20 hours.

The cross compiler on Raspberry had problems with some mmx instructions,
i do not recall the exact error. Anyway, setting the --disable-asm option helped
and was the only problem. Dirty patch of mine.

Cheers
Dennis

Ok could you post the exact error message so followers can find this? Then
I guess I'll close it and let people manually adjust if they run into it?

When compiling for Win32 on a RaspberryPi with Debian Wheezy, You might
encounter the following error log and compiling terminates:

...
Found GNU assembler (GNU Binutils for Debian) 2.22
Minimum version is binutils-2.17
Your compiler can't handle inline SSSE3 asm.
If you really want to compile without asm, configure with --disable-asm.

Just add "--disable-asm" manually to the xavs configure and everything works fine.

awesome thanks!

from ffmpeg-windows-build-helpers.

I wonder why it says "binutils" cannot handle SSE3. Odd.

(note for followers that disabling asm might slow down the final executable
I suppose...well if they ever end up using xavs which is pretty rare I must
imagine...)

I belive, the asm sources are not correct prefixed with cross compile settings and the binutils were the native arm binutils.

from ffmpeg-windows-build-helpers.

Judging from how much support I got from this ticket: https://sourceforge.net/projects/xavs/forums/forum/551032/topic/6136352 I don't have much hope of this ever being fixed, so thanks for posting the work around instructions :)

from ffmpeg-windows-build-helpers.

I tried Your workaround which no luck.

do_make_install "CC=$(echo $cross_prefix)gcc AR=$(echo $cross_prefix)ar PREFIX=$mingw_w64_x86_64_prefix RANLIB=$(echo $cross_prefix)ranlib STRIP=$(echo $cross-prefix)strip"

Anyway, the STRIP part has a mistake, there is a hyphen in cross_prefix instead of an underscore.

I am still working on this issue. I am not getting past the configure...

from ffmpeg-windows-build-helpers.

I have debugged the xavs configure now and found the problem. It needs --cross-prefix for configure.

build_libxavs() {
do_svn_checkout https://xavs.svn.sourceforge.net/svnroot/xavs/trunk xavs
cd xavs
export LDFLAGS='-lm'
generic_configure "--cross-prefix=$cross_prefix" # unfortunately this using --host isn't enough apparently...
unset LDFLAGS
do_make_install
cd ..
}

The only caveat is, that configure prefers a local native yasm for asm compiling (no prefixing here, which is just what we need). Since i have that installed on my Raspberry Pi, it works like a charm.

I still have to check if ffmpeg.exe is finally linkable and running ok.

from ffmpeg-windows-build-helpers.

what if you use --cross-prefix and --host maybe?
Just wondering, thanks for debugging it.

Since it worked anyway, i did not try it.

Ok I have attempted to use your suggestions in 4d374e7 (and at least it doesn't hurt it in ubuntu so we're good there). I think using native yasm is ok as long as it calls it like "yasm -f win32" or the like. Thanks for your contribution! -r
