32bit build log
Updated build log with patch |

I think the issue is in egl - mesa builds fine on 32bit without it The 64bit version builds fine with it I've bisected it back to: b07ae05a3dccef620c716e821c647413b951051 is the first bad commit commit ab07ae05a3dccef620c716e821c647413b951051 Author: Matt Turner <mattst88@gmail.com> Date: Wed Sep 5 11:12:29 2012 -0700 targets/dri-r600: Convert to automake v2: Andreas Boll <andreas.boll.dev@gmail.com> - Provide compatibility with scripts for the old Mesa build system :100644 100644 9c9791b5137525bb22de3439806d565411a698aa bb287d776c71a849f627af941bdbe0d514282ea1 M configure.ac :040000 040000 097ecdc98b02d01f522d90cae259f846fac14d64 c3659daefaf1f71454c058590a87603c250d4458 M src But I don't think that's much of a surprise and might be a bit of a red herring I've got a feeling the -m32 probably isn't being passed somewhere I notice in the glsl directory the Makefile has CFLAGS and CFLAGS_FOR_BUILD and the same for CXX too the FOR_BUILD ones don't have -m32 and I think could be causing some of the issues I'm seeing Thanks. I know about this. Trying to come up with a good solution.

Looks like this is yet another problem with 32-bit LLVM. I wonder if Tom's seen this? Even with the llvm switches set to off I still have issues (In reply to comment #6) > Even with the llvm switches set to off I still have issues Maybe this patch helps: http://lists.freedesktop.org/archives/mesa-dev/2013-January/033797.html It's an improvement I can build mesa again without EGL building with EGL I get errors such as: ../../../../src/gallium/auxiliary/.libs/libgallium.a(lp_bld_debug.o):lp_bld_debug.cpp:function lp_disassemble: error: undefined reference to 'std::string::_Rep::_S_empty_rep_storage' ../../../../src/gallium/auxiliary/.libs/libgallium.a(lp_bld_debug.o):lp_bld_debug.cpp:function lp_disassemble: error: undefined reference to 'std::string::_Rep::_S_empty_rep_storage' ../../../../src/gallium/auxiliary/.libs/libgallium.a(lp_bld_debug.o):lp_bld_debug.cpp:function lp_disassemble: error: undefined reference to 'std::string::_Rep::_S_empty_rep_storage' ../../../../src/gallium/auxiliary/.libs/libgallium.a(lp_bld_debug.o):lp_bld_debug.cpp:function lp_disassemble: error: undefined reference to 'std::string::_Rep::_S_empty_rep_storage' /usr/lib32/llvm/libLLVMX86CodeGen.a(X86FrameLowering.o):function emitSPUpdate(llvm::MachineBasicBlock&, llvm::MachineBasicBlock::bundle_iterator<llvm::MachineInstr, llvm::ilist_iterator<llvm::MachineInstr> >&, unsigned int, long long, bool, bool, llvm::TargetInstrInfo const&, llvm::TargetRegisterInfo const&): error: undefined reference to 'std::_Rb_tree_decrement(std::_Rb_tree_node_base*)' /usr/lib32/llvm/libLLVMX86CodeGen.a(X86FrameLowering.o):function emitSPUpdate(llvm::MachineBasicBlock&, llvm::MachineBasicBlock::bundle_iterator<llvm::MachineInstr, llvm::ilist_iterator<llvm::MachineInstr> >&, unsigned int, long long, bool, bool, llvm::TargetInstrInfo const&, llvm::TargetRegisterInfo const&): error: undefined reference to 'std::_Rb_tree_decrement(std::_Rb_tree_node_base*)' Created attachment 74012 [details]
Updated build log with patch
I had to compress it due to the size
Equally disabling llvm and leaving egl on works too Seems I had a rogue /usr/lib32/libstdc++.so causing problems with my 32bit builds Everything is working fine now with LLVM enabled |

Created attachment 72977 [details] 32bit build log I can no longer build a 32bit mesa on my 64bit system I'm using the same options and using master on both builds I think this might have something to do with the autotools merge
