Description farmboy0+freedesktop 2014-04-15 21:30:02 UTC
I have just rebuilt mesa from git on my system and the OpenVG library doesnt contain any symbols that start with vg anymore.
This makes compilation of other libs and programs fail like cairo.

Step to reproduce:
1. ./configure --enable-glx --enable-shared-glapi --enable-texture-float --enable-egl --enable-gbm --enable-gles1 --enable-gles2 --enable-glx-tls --enable-osmesa --enable-asm --with-dri-drivers=swrast,radeon --with-gallium-drivers=swrast,radeonsi,r600 --with-egl-platforms=x11,wayland,drm --enable-gallium-llvm --enable-openvg --enable-gallium-egl --enable-dri --enable-xvmc --enable-dri3 --enable-vdpau --enable-r600-llvm-compiler --enable-debug

2. gmake
3. check the symbols of src/mapi/vgapi/.libs/libOpenVG.so.1.0.0

I am using python 2.7.
Comment 1 Emil Velikov 2014-04-18 20:34:13 UTC
Can you use git to bisect the commit that introduced this issue? Commit d681b22ed77274a805c6c8e81925c18eeb57a968 is the highest suspect, interestingly the vg symbols were available last time I built the library.

What version of gcc/binutils are you using ?
Comment 2 farmboy0+freedesktop 2014-04-18 21:51:10 UTC
GCC: 4.7.3
Binutils 2.23.2

I'll do the bisect later but I think its not your mentioned commit.
I checked the latest changes to the Makefile for vgapi and reverted them and nothing got better.

the commit that introduced this regression is 75143ef05576ee9f25ee176bc28c3c4d03705bf5 

I've got hit by this bug too, cannot update at least 3 pkgs on my system (using Gentoo).

what is worst is that include/VG/openvg.h exposes the vg* api while the code uses the vega* api.

frankly I'm not sure how this commit was approved, it broke backwards comparability and is partial.

Did you try the next commit (34f15903d6f5807b34a4c9be6d8daaedbbdd64bc)? It fixed a mistake in the patch this was bisected to.
Comment 7 farmboy0+freedesktop 2014-04-22 19:03:33 UTC
Tried now.
Still bad.
Comment 8 Emil Velikov 2014-04-22 19:52:14 UTC
Dagg,
The issue introduced by 75143ef05576ee9f25ee176bc28c3c4d03705bf5 is different from this one. Please try to keep one bugeport per issue - open a new ticket and add the commit author to the Cc list.

Matt,
I'm guessing that you will be able to easily reproduce, at least I did without even trying (don't think I'll have time to look into it any time soon).

Just an idea: considering the way the whole dispatch is build (almost every time 2 different libraries are built), we might be off moving the headers to noinst_HEADERS. That will keep automake/make dist happy.

Emil,

I'm not sure how you've decided is different from this one, I get a bunch of undefined reference to `vg*' errors on linking for multiple pkgs, looking at the title and at the commit I've mentioned, it shows that the exact vg funcs are replaced by vega funcs.

nonetheless, I'll open an new bug on the matter.

In this commit, entry.c is removed from $(MAPI_FILES) in src/mapi/Makefile.sources.  Adding it back should fix this bug.  (Sorry that I am about to board a plane to verify it)

Would you attach a git-formatted patch, preferably with your real name, etc? I'll commit that.
