Building wine with profile generation

Ema · Post by **Ema** » Sat Feb 14, 2009 4:32 am

Hi all,

I'm trying to build wine with the following command:

./configure CFLAGS="-O2 -fprofile-generate" --prefix=/home/ema/winepf

As I have a lot of these errors:

Code: Select all

gcc -O2 -fprofile-generate -o sfnt2fnt sfnt2fnt.o -L../libs/wine -lwine ../libs/port/libwine_port.a  -lfreetype -lz -Wl,--rpath,\$ORIGIN/../libs/wine
/usr/bin/ld: sfnt2fnt: hidden symbol `__gcov_merge_add' in /usr/lib/gcc/i486-linux-gnu/4.3.2/libgcov.a(_gcov_merge_add.o) is referenced by DSO
/usr/bin/ld: final link failed: Nonrepresentable section on output
collect2: ld returned 1 exit status
make[1]: *** [sfnt2fnt] Error 1

So I have to start amend the single Makefiles for every subdirectory that doesn't compile.
Has anyone any solution tocompile the full wine with -fprofile-generate flag?

I'd really like to optimize it but...I got a huge amount of these errors...
Cheers,

Looking at http://www.gp32x.com/board/index.php?sh ... 8490&st=15,
says make distclean may be needed, as well as an LDFLAG...

make distclean ; CFLAGS="-fprofile-generate"
LDFLAGS="-fprofile-generate" ./configure && make depend && make

works for me, past that point, then fails:

How was the error? Have you corrected it already? I am interested to build a profile generation too.

Failed

Anyone knows why?
Cheers,

edit

I has a fast look and could be that the issue is within winegcc?
Tbh I don't know exactly why wine uses winegcc (should be a wrapper to fake mingw?) to compile instead of gcc/g++ directly, but probably isn't that option not supported in winegcc and isn't passed to the linker?

Guys, any news?
Anyone does know how to make it run?

Note that oprofile works fine in combination with Wine it doesn't require patching. Sometimes I also used gprof for some more detailed profiling and for that I added the -pg option to the cflags of the wine dlls I wanted to analyze. I don't think you can build all wine parts with such options on.

With -fprofile-generate you start using tree and gcc/g++ will optimize analyzing those as well. Oprofile is old technology compared to this one.

Should I profile the single DLLs then in your opinion?
