Build failure ...

[g40]

Hi, any thoughts welcomed here. Not sure if the cmakefile is missing some -l flags or what.

Downloaded a source tarball onto host machine:

The usual cmake dance:

I also bumped into some of these linking errors on mac OS. In my case, the four missing references related to ncurses (*term) could be found after adding ncurses in
utils/genJitGlobalMap/CMakeLists.txt:

target_link_libraries(
  genJitGlobalMap
  ncurses
  ${LLVM_LIBRARIES}
  ${LLVM_LDFLAGS}
  )

Try adding pthread and whatelse you see from the outputllvm-config --system-libs

In my case, the compilation continues but then breaks when reaching lib/JIT.cpp:

JIT.cpp:196:3: error: use of undeclared identifier 'LLVMLinkInJIT'; did you mean 'LLVMLinkInMCJIT'?
JIT.cpp:238:3: error: use of undeclared identifier 'LLVMAddTargetData'

This seems because I tried compilation with too recent versions of LLVM (5.0 and 6.0).
The function LLVMAddTargetData() was dropped with LLVM 3.9 and I have troubles installing an older version than 5 using homebrew on macOS. So far I end up with post-fixed llvm-*-3.7 commands which are ignored by cmake. Anyone knows how update AXE to make it compatible with never LLVM versions? @rlsosborne @arp2600
