[LLVMdev] Fwd: [llvm-commits] [PATCH] Building llvm-gcc with llvm-2.5 debian packages
Hi Pekka,> To put it the another way: is there a reason to disallow > compiling llvm-gcc (optionally) against an installed LLVM (e.g. > from the Debian package)? It seems to work fine with this patch > Mikael posted.I think it would be great if llvm-gcc could be built against an installed LLVM. However my impression was that Mikael's original patch would break building against an not-installed llvm. Ciao, Duncan.

The patch would just fix llvm-gcc build system to be able to compile with both, *llvm build in source directory* and *installed llvm version*. Correct include directory can be get with llvm-config --includedir, because when llvm-config is excuted from llvm source tree (from Release or Debug directory) it will return the include directory of source tree (e.g. llvm-2.6svn/include). If llvm-config is called from installation path it returns include directory of installed llvm includes. I tried the patch with compiling llvm-gcc with: - llvm-2.5 source tree build - installed llvm-2.5 from sources - apt-get installed debian llvm-2.5 packages. I will try if the patch works correctly with llvm trunk as well and show also the compile commands which were used to configure and compile the llvm-gcc. - Mikael> Ciao, > > Duncan. > _______________________________________________ > LLVM Developers mailing list > LLVMdev at cs.uiuc.edu http://llvm.cs.uiuc.edu > http://lists.cs.uiuc.edu/mailman/listinfo/llvmdev
