Comment:
I want to use the llvm package in GHCi.
To this end I converted all of the libLLVM*.a files to local libLLVM*.so.
When I start the main function of a Haskell program using LLVM functions
then I get the known:
{{{
Loading package llvm-0.6.7.0 ... can't load .so/.DLL for: pthread
(/usr/lib/libpthread.so: invalid ELF header)
}}}
My libpthread.so is also a script like that shown by Christian Maeder.
However, pthread is not mentioned in llvm wrapper source files.
It only appears in the files generated by configuration.
{{{
$ grep -r pthread .
Match in binary file ./dist/setup/setup.
./config.status:S["llvm_ldflags"]="-L/usr/lib/llvm -lpthread -ldl -lm "
./config.status:S["LDFLAGS"]="-L/usr/lib/llvm -lpthread -ldl -lm "

}}}
Where do I have to remove pthread?
