Extended Description

Originally filed as #120

[zmodem]

Serge has a patch out here: https://reviews.llvm.org/D74464

[zmodem]

Based on #120 it sounds like there are still issues.

[zmodem]

I'm not going to block on this.

[sylvestre]

Hans, FYI, we have to take the patch in Debian/Ubuntu packages to fix a link issue with mesa
should be probably in 10.0.1

From #191 it sounds like it's not clear that D74464 helps?

[sylvestre]

Oh, having two bug trackers isn't optimal :(

Anyway, the patch I am talking about hasn't been uploaded yet

[tjaalton]

I've tested the package with the patch, and it didn't help. So I'm still unable to build mesa, and now hitting the same bug trying to build intel-opencl-clang.

[sylvestre]

Could you please provide a test case which would not be "rebuild mesa" ? :)
thanks

[tjaalton]

Well, build intel-opencl-clang instead? Much quicker..

[Meinersbur]

Could you check whether 3a0f6e6 and 87dac7d fix the issue?

[tjaalton]

thanks, I will!

[tjaalton]

nope, didn't help, still get the same error..

Jan Palus shared this STR with me:

With Debian packages, the command is:
$ g++ a.cpp -o test -lclangBasic -lclangCodeGen -lclangDriver -lclangFrontend -lclangFrontendTool -lclangCodeGen -lclangRewriteFrontend -lclangARCMigrate -lclangStaticAnalyzerFrontend -lclangStaticAnalyzerCheckers -lclangStaticAnalyzerCore -lclangCrossTU -lclangIndex -lclangFrontend -lclangDriver -lclangParse -lclangSerialization -lclangSema -lclangAnalysis -lclangEdit -lclangFormat -lclangToolingInclusions -lclangToolingCore -lclangRewrite -lclangASTMatchers -lclangAST -lclangLex -lclangBasic -ldl /usr/lib/llvm-10/lib/libLLVM-10.so -lclangCodeGen -lclangDriver -lclangFrontend -lclangFrontendTool -lclangRewriteFrontend -lclangARCMigrate -lclangStaticAnalyzerFrontend -lclangStaticAnalyzerCheckers -lclangStaticAnalyzerCore -lclangCrossTU -lclangIndex -lclangParse -lclangSerialization -lclangSema -lclangAnalysis -lclangEdit -lclangFormat -lclangToolingInclusions -lclangToolingCore -lclangRewrite -lclangASTMatchers -lclangAST -lclangLex -ldl -I /usr/lib/llvm-10/include/ -L/usr/lib/llvm-10/lib/

[Meinersbur]

-Polly, -lPollyPPCG and -lPollyISL are missing.

Where does the list of libraries come from? llvm-config?
