Description Alexandre Demers 2011-06-27 08:51:13 UTC 
When compiling, it ends with:

As asked, nm and grep give me:

Comment 1 Chia-I Wu 2011-06-27 23:26:47 UTC 
The command for linking wrongly put the local library search path after the system's.  It should be fixed with 24137af.  Please test.
Comment 2 Alexandre Demers 2011-06-28 04:01:44 UTC 
It is now fixed and I'm able to build properly. Thanks.
Comment 3 Alexandre Demers 2011-06-28 04:18:10 UTC 
Reopening. When building 32bit on 64bit system, the same error appears:

../../../../src/gallium/state_trackers/egl/libegl.a(egl_g3d_api.o): In function `egl_g3d_choose_config':
/home/dema1701/projects/mesa/mesa/src/gallium/state_trackers/egl/common/egl_g3d_api.c:140: undefined reference to `_eglFilterConfigArray'
collect2: ld returned 1 exit status


And doing:
nm -D i386-linux-gnu/libEGL.so | grep _eglFilterConfigArray
doesn't grep anything, even though removing grep ... does return many things.
Comment 4 Chia-I Wu 2011-06-28 04:30:59 UTC 
Is your i386-linux-gnu/libEGL.so outdated?  It should have the symbol.  (another place to check is src/egl/main/eglconfig.o where the symbol is defined)
Comment 5 Alexandre Demers 2011-06-28 04:41:56 UTC 
Obviously, after verifying, i386-linux-gnu/libEGL.so shouldn't be outdated since I always make a "make realclean" at the beginning and the file is then removed (checked). I understand the symbol should be there, but it seems it's not. _eglFilterArray is, but not _eglFilterConfigArray.

How am I supposed to check if src/egl/main/eglconfig.o contains the symbol definition?
Comment 6 Chia-I Wu 2011-06-28 05:04:06 UTC 
You can still use nm like

 $ nm src/egl/main/eglconfig.o

Could you also attach your build log of building src/egl/main?  It might shed some light.
Comment 7 Alexandre Demers 2011-06-28 09:02:33 UTC 
I'll look at it when I'll get home tonight.
Comment 8 Alexandre Demers 2011-06-28 21:05:19 UTC 
Here are some different results:

-nm -D src/egl/main/eglconfig.o | grep eglFilter
nm: src/egl/main/eglconfig.o: No symbols

-nm src/egl/main/eglconfig.o | grep eglFilter
         U _eglFilterArray
00000c30 T _eglFilterConfigArray

-nm i386-linux-gnu/libEGL.so | grep eglFilter
00000000000089c0 T _eglFilterArray

and obviously
nm -D i386-linux-gnu/libEGL.so | grep eglFilter
00000000000089c0 T _eglFilterArray

I'll attach my log in a couple of minutes.

Full log

using:
make realclean
./autogen.sh --enable-32-bit with some other options
make -j 12
Comment 10 Chia-I Wu 2011-06-28 23:09:28 UTC 
"make realclean" did not seem to remove your i386-linux-gnu (it did "rm -rf lib*").  When building libEGL later, it failed because 32-bit xcb-{dri2,xfixes,shape} were missing.  So you still got the outdated libEGL.
Comment 11 Alexandre Demers 2011-06-29 12:35:58 UTC 
Yes, you are right, I now know mostly why. Last time libEGL was written was in April under i386. So it seems something is preventing libEGL from being recreated since then. I can't remember what I changed then.

However, since I'm on a 64bit and compiling a 32bit version of mesa, it seems I'm now trapped with a new dependency problem. I can't install both 64 and 32bit dev files. I could use chroot probably, but I've never liked that solution. Well, if I want to be able to compile 32bit Mesa to let Wine play well, I don't see any other solution for now. I *could* rely on ia32 libs on Ubuntu, which is a real nightmare. Or I could try to build Wine64 instead, which is probably what I'll do.

That said, thanks for everything. I'm closing the bug as it was before reopening since the original problem was a real bug.



Note: "make realclean" should have removed the file libEGL.so.1.0 though, it would have pointed at the problem a lot sooner.

I am using Debian Sid amd64 but still can't compile the gallium EGL driver.I cloned the latest git and 'make' shows:

libEGL.so is missing.  Could you switch to src/egl/main/ and "make" from that directory?
