Installing Lua version: LUAJIT21
CMake Error at exe/luajit-rocks/luajit-2.1/CMakeLists.txt:156 (MESSAGE):
Cannot compile a useful lua.
Function dlopen() seems not to be supported on your platform.
Apparently you are not on a Windows platform as well.
So lua has no way to deal with shared libraries!
I discovered the reason so I thought I would explain it here.
As I searched the web, this seems to be a very common problem: ' finding dlopen '
Although I can not answer it a 100% cure on all computers, I found the problem was
when I updated to Ubuntu 18.04 bionic it also updated my gcc to version 8. No matter what I did I could not get version gcc:8.0.0 to find dlopen() when I was installing torch. I installed gcc-4.9.0 and everything worked fine. Torch was not the only program that could not compile because of the upgrade and gcc-8
