llvm dev - Sep 2010 - [LLVMdev] llvm-config error

Hello,

Takumi, you are absolutely right! It was a problem with Perl. Many thanks!
That problem solved, tried to compile again the kaleidoscope example but
unfortunatelly now I get the link errors found bellow:



$g++ -g –O3 toy.cpp `llvm-config –cppflags –ldflags –libs core`-o toy

I built again LLVM now with perl working properly.
Any help would be great
Antonio

Good afternoon, António.

I guess it might be a known issue;
http://llvm.org/bugs/show_bug.cgi?id=3347

Would you like me to show the result of "llvm-config –cppflags
–ldflags –libs core"?
And please try specifying libs (-lLLVMCore -lLLVMSupport -lLLVMSystem
-lpsapi -limagehlp -lm) manually.

Hi, Takumi!


Running llvm-config --cppflags –-ldflags –-libs core gives:



-Ic:/llvm-source-2.7/include –I/c/llvm-2.7/include –D_DEBUG
–D__NO_CTYPE_INLINE –D_GNU_SOURCE –D__STDC_LIMIT_MACROS
–D__STDC_CONSTANT_MACROS -L/c/llvm-2.7/Release/lib –lpsapi –limagehlp –lm
–lLLVMCore –lLLVMSupport –lLLVMSystem

I followed your suggestion and changed libs order manualy to:

–lLLVMCore –lLLVMSupport –lLLVMSystem –lpsapi –limagehlp –lm

and it worked like a charm !!! Everything compiled fine!

Many many thanks!!
Antonio
