Description Deathwing00 2008-06-03 09:48:52 UTC
Version:            (using KDE 3.5.9)
Installed from:    Gentoo Packages
Compiler:          gcc-4.3.0 glibc-2.7-r2, kernel 2.6.25-gentoo-r4 x86_64
OS:                Linux

Downstream: https://bugs.gentoo.org/show_bug.cgi?id=224611

User reports that the current digikam version compiles with gcc 4.2.4 but hangs at the following point with gcc 4.3.0. Patch requested.

CFLAGS="-march=native -O2 -fomit-frame-pointer -pipe"

Actual Results:
Compilation gets to the following point and hangs with ~100% cpu usage on one

Comment 1 caulier.gilles 2008-06-03 09:55:24 UTC
This problem have been already reported here. It's fully relevant of CImg.h file taken from CImg library verion 1.2.8 which do not compile fine under GCC 4.3

Please report this problem into CImg bugzilla.


Thanks in advance.

Comment 3 Andi Clemens 2008-06-03 13:07:58 UTC

to compile it anyway, set full debugging in configure like this:

./configure --prefix=<path_to_KDE> --enable-debug=full

No optimizations will be made and it should work fine. This is just a temporary solution, but it will work.
Comment 4 Rex Dieter 2008-06-03 14:13:13 UTC
fwiw, beta5 built fine here on fedora (f10/rawhide) using gcc-4.3.
Comment 5 Deathwing00 2008-06-04 08:23:27 UTC
Seems to fail to compile with -O3 and -O2, but it does work with -O1.
Comment 6 Andi Clemens 2008-06-04 09:02:42 UTC
I'm not sure if it really hangs or if it just takes too long, I once was able to compile beta5 with standard settings (-O3) and it took only 1 minute (not the whole application :-) only the greycstoration part).
So nobody actually seems to know what is going wrong here, some distributions with gcc-4.3 compile fine, others don't.
Another possibility is to go into the specific folder (libs/greycstoration) and call make from in there without optimizations. Then go back to the digikam root folder and compile the rest with the optimizations you like to have set. This way it should compile fine, too.

On some arch's it fails and other it succeeds:
2:0.9.4~beta5-1 (amd64) (latest build at May 31 01:57: maybe-successful)
2:0.9.4~beta5-1 (i386) (latest build at May 31 02:07: maybe-successful)
2:0.9.4~beta5-1 (alpha) (latest build at May 31 03:27: maybe-successful)
2:0.9.4~beta5-1 (ia64) (latest build at May 31 04:10: maybe-failed)
2:0.9.4~beta5-1 (s390) (latest build at May 31 04:14: maybe-failed)
2:0.9.4~beta5-1 (sparc) (latest build at May 31 05:07: maybe-failed)
2:0.9.4~beta5-1 (hppa) (latest build at May 31 20:40: maybe-failed)
2:0.9.4~beta5-1 (mipsel) (latest build at Jun 2 07:57: maybe-failed)

With gcc-4.2 it builds fine, I presume with the patch they will build fine too.
Comment 10 caulier.gilles 2008-06-15 19:26:09 UTC

Talking with MAndriva team today, it sound like to use this directive : 

export CXXFLAGS="%optflags -fno-tree-pre

...before to compile fix the problem with gcc 4.3.x. Can you confirm this ?

Comment 12 Andi Clemens 2008-06-15 19:45:21 UTC

I went into digikam/libs/greycstoration, running "make clean". Then I started "make -f Makefile.cvs && ./configure --prefix=/opt/kde --enable-final" to generate the new makefiles.
After that I went back to digikam/libs/greycstoration and "make" took 20 seconds... so it seems to work for me.

Thanks Andy. I can close this file now.

Comment 15 Andi Clemens 2008-06-16 12:29:49 UTC
Yesterday a new version of gcc arrived in Archlinux (gcc-4.3.1), but this seems to compile well, too. So I think it is ok to close it...
