I’m trying to build some code that relies on LLVM as a library (out-of-source). It uses llvm-config for the compilation & linkage flags. Some recent change breaks it, and with the newest trunk LLVM I get:
/home/eliben/llvm/build_llvm_svn_rw/Debug+Asserts/lib/libLLVMSupport.a(Process.o): In function terminalHasColors': /home/eliben/llvm/llvm_svn_rw/lib/Support/Unix/Process.inc:256: undefined reference to setupterm’
/home/eliben/llvm/llvm_svn_rw/lib/Support/Unix/Process.inc:274: undefined reference to tigetnum' /home/eliben/llvm/llvm_svn_rw/lib/Support/Unix/Process.inc:278: undefined reference to set_curterm’
/home/eliben/llvm/llvm_svn_rw/lib/Support/Unix/Process.inc:279: undefined reference to `del_curterm’
collect2: ld returned 1 exit status
I don’t know a workaround which will keep support for coloured terminal output, but if you can live without it then passing these to configure should work.
Thanks for the suggestion, Pete. Another thing that works is pass -ltinfo
manually instead of using llvm-config. I just want to figure out why
llvm-config doesn't "get" that curses was found. I'll try to do some more
diagnosis and add information to the open bug.

--enable-curses=no
--enable-terminfo=no
Re-doing the configure & build in a new directory solved the problem for
me. I think the problem had to do with the fact that my previous svn update
on this machine was before Chandler's curses-related changes, and I then
ran 'make update' which used the old configure script. I've updated the PR
- maybe the OP had the same problem.
FWIW, Pete, the --enable-curses option to configure no longer exists.
configure just ignores it. Chandler removed it in r188160.
