When I try to run make from msys it fails at opt.exe with about 7000 "undefined reference" errors in AnalysisWrappers.o. This happens with 2.8, 2.9 and the SVN versions.

Operating system: Windows 7 (64-bit)

Do you have msys perl installed? Or you're using ActivePerl?

[Quuxplusone]

I'm using perl "v5.8.8 built for msys-64int".

Please attach the whole console output for the error.

Please attach the same file for "make VERBOSE=1"

It looks like not all necessary libraries are linked in. This might be due to
broken llvm-config which, in turn, might be due to broken perl / system tools.
The latter is quite probable given that everything works for me and for bunch
of other people for 2.8, 2.9 and svn tot.

Which tools does this exactly refer to? I installed MinGW/MSYS using the
installer available from mingw.org, which automatically downloads the newest
version of everything. Are there "less broken" versions than that somewhere?

[Quuxplusone]

I have fixed it by putting the MSYS bin directory to the beginning of %PATH%
(previously it was at the end). Also I had to put the external tools like
graphviz and doxygen out of the "Program Files" directory and into a directory
with no space in the name.

Now make runs successfully. During make install, sometimes I got the error that
strip.exe couldn't create a file because it already exists, but after a few
runs it went through.

Now the only remaining problem is that the following libraries don't get
created:
-lLLVMXCoreAsmPrinter
-lLLVMSystemZAsmPrinter
-lLLVMSparcAsmPrinter
-lLLVMPIC16AsmPrinter
-lLLVMPIC16CodeGen
-lLLVMPIC16Info
-lLLVMMSIL
-lLLVMMSILInfo
-lLLVMMipsAsmPrinter
-lLLVMDebugger
-lLLVMCellSPUAsmPrinter
-lLLVMBlackfinAsmPrinter
-lLLVMAlphaAsmPrinter
-lLLVMSystem

I supposed MSYS bash shell login script might insert his path at first.

Greetings. I've been engaged on an adventure building LLVM on MinGW32 for the past three days, and I've come to that journey's end.

I (hopefully completely) documented what I did in the wiki for a project I was hoping to use LLVM for (llvmpy, actually, but that's a different story).

If you follow the instructions here: https://github.com/valtron/owl/wiki/Build-LLVM-with-MinGW32-and-MSYS, you should be able to build LLVM and compile and run the Kaleidoscope example.

I plan to post a bug report for llvm-config.cpp once I get a diff in order. But I'm posting this here (even though this bug is over a year old) hoping that this information will be helpful to others using MinGW.
