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

Hi

I’m having a few problems building the kaleidoscope example (chapter 3)
under MinGW. To build the example I use as recommended



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



but get the following error



sh: llvm-config: command not found



Indeed in my “\llvm-2.7\tools\llvm-config\” build directory  there is no
“Release” subdirectory as I would expect (only  llvm-config.in among other
files) and in \llvm-2.7\Release\bin no llvm-config executable (only
a llvm-config text file). This was a little unexpected  because otherwise
llvm appears to have been built fine and llvm object directory tree also
looks OK.



What I am doing wrong? Any help would be much appreciated!

You need MSYS's perl to use llvm-config on mingw.

Does this below work?
-D_DEBUG (might be -DNDEBUG)
-D__NO_CTYPE_INLINE
-D_GNU_SOURCE
-D__STDC_LIMIT_MACROS
-D__STDC_CONSTANT_MACROS
-lLLVMCore -lLLVMSupport -lLLVMSystem
-lpsapi -limagehlp -lm

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:

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