Compiling GCC for MinGW & Cross-Compiling with Linux

[Kurosu]

'thunk alias' error still happens with the baseclasses in ffdshow

See this gcc bug report:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27067

Patch worked fine on the 20060715 gcc 4.2 snapshot, but probably can't be merged properly now.

latest time tried i patching gcc-4.2-rev121020 it was fine, but i failed to get it to worked with later revisions, maybe it will get intergrated into the trunk

i patched gcc-4.1.2 http://forum.doom9.org/showthread.php?p=953608#post953608

cheers

[cc979]

i just uploaded a cross-compiled gcc-4.3 for anyone who wants try it

http://www.mytempdir.com/1278497

libgomp/pthreads/gmp/mpfr are included

cheers

just read on mingw news:
Snapshot: mingw-w64-headers-20070405-1.tar.bz2 2007-04-05 00:33
Header set for x86_64-pc-mingw32 support. This is a header set tested only for x86_64 version, but it includes also the definitions for x86 and ia64, too. It was used to build and verify the patch to gcc 4.3 (trunk) and may also it has some use to mingw.

Can you please upload all mingw builds to rapidshare?
mytempdir doesn't work.

i don't keep them, i delete them once uploaded

will be building prerelease-4.2.0-20070501 soon

[Lemonzest]

any word on a build of 4.2.0 final? it was released today :) thanks

[morph166955]

I just heard about it a few mins ago. I'm going to play around with it later today (in linux though till i get my footing all with it). I don't have my mingw setup on this box so I can't make a build for everyone to use. cc979 might but I don't know what his plans are.

[dancho]

just in case that someone maybe need it:

unofficial MinGW 4.3.0 gcc and g++ PATCHED against 27067 bug ( big thx to 20-40 )

[cc979]

been little busy will build gcc 4.2.0 now, that is if ubuntu works had trouble with nvidia driver latest ubuntu

[morph166955]

cc979...are you doing your gcc builds strictly cross-compile now or are you doing them native in mingw/msys?

I'm may do a 4.2 native compile today myself, if not ill do it some time next week if I have time among compiling my own linux distro (see the linux section for my post that has more info).

[cc979]

just finished a linux-cross-compiled version of gcc-4.2 - which i will do for all gcc builds, i stopped doing windows native builds a while back

i just need to upload it now, will be later - after a few tests

cheers

ps. just tested gcc-4.2.0 with latest svn of ffdshow-tryout - looks like the thunk alias patch did not make into the final release

Thanks!

Edit: Did you forgot to strip the binaries? They seem rather big compared to the older versions.

no should be stripped, there are larger than 4.12 irc

It is possible to cross-compile libavcodec with icc9?

[cc979]

It is possible to cross-compile libavcodec with icc9?

no idea,
the cross-compile - you need to have/make compiler the runs on linux that creates code for windows unless that icl9 thing does have an already cross-compiled compiler its unlikely - but maybe someone who knows more about icl9 on linux would tell you

cheers

Could you make a GCC 4.2.1 mingw build? It was released last week. Thanks.

[Romario]

What about new ICL 10, why somebody don't compile FFDSHOW with that version?

i will asap, been a little busy lately

There are newer versions: runtime 3.12 and w32api 3.9

[cc979]

3.12 runtime headers was buggy, last time i used it

[cweb]

anyone tried 3.13 runtime?
w32api-3.10 is out too..

[DeathTheSheep]

Would anyone know where to get a cygwin GCC-4.3 binary? I would think this is the place to ask.

[cc979]

probably need to compile one, i would try but i dont use cygwin

[cc979]

out of curiosity how many would want a mingw64 build of gcc & binutils ?

[clsid]

That would be very useful for compiling libavcodec. That would give a big performance boost for ffdshow 64-bit, which is currently much slower than the regular 32-bit version.

But is there already a 64-bit version of the mingw environment?

[cc979]

i will look into it further

[MatMaul]

can we have a 4.2.2 build please :p

[cweb]

can we have a 4.2.2 build please :p
How reliable are these 4.2.x builds? Are they able to compile all the stuff you can throw at them or are there some problems/bugs etc...?

[cc979]

i shall build it soon

Can you make a fresh build of GCC 3.4.6? Thanks.

[cc979]

old one, any reason ?

will do i get time - soon

[Inventive Software]

If you have a fresh MinGW, you can compile 3.4.6 yourself. I have done it before....

[clsid]

I don't have msys installed. So that won't work.

I want 3.4.6 because I want to test the performance of the code that it generates compared to 4.2.2.

I can't compile ffdshow.ax using MinGW-GCC 4.2.2.

I created a small sample to reproduce the error.

struct Ifoo
{
virtual void __stdcall stdcallfunc(void)=0;
};

struct foo
{
virtual void cdeclfunc(void);
};

void foo::cdeclfunc(void){}

struct fooImp: public foo, public Ifoo
{
virtual void stdcallfunc(void) __attribute__((stdcall));
virtual void cdeclfunc(void){};
};

void fooImp::stdcallfunc(void){}



gcc -S foo.cpp
foo.cpp:18: error: 'void *LTHUNK0()' aliased to undefined symbol '_ZN6fooImp11stdcallfuncEv'


Is this a bug of GCC or MinGW?
If we can confirm that this is a bug, I'll write a report.

My guess is it's a bug in stdcall compiling.
I think '_ZN6fooImp11stdcallfuncEv' should be '_ZN6fooImp11stdcallfuncEv@4'.

[cc979]

it a bug of gcc 4.2+ there was a fix, but it seems it did not make it into the svn

Thank you for reply. It seems to have been committed in the trunk after creating 4.2 branch as rev 125020 (http://gcc.gnu.org/viewcvs?view=rev&revision=125020).
I expect GCC 4.3 will be able to compile ffdshow.ax again.

[cc979]

i've made a test build of:
gcc version 4.2.3 20071226 (prerelease)

it seems it does not have the patch http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27067

i'll try adding it later
