Install ree-1.8.7 with RVM on Mountain Lion

Question

I had a fresh install of Mountain Lion and installed the Xcode Command Line Tools, . I was able to get homebrew running and installed RVM. Unfortunately, I can't get RVM to install ree-1.8.7-head. It fails when compiling. I thought it was related to X11, so I installed XQuartz. Still no joy. Then I went ahead and installed the full Xcode from the app store. Still no joy. Anyone gotten this going on a fresh Mountain Lion install? From the bottom of the .rvm/log/ree-1.8.7-head/make.log: ``` Find Tcl/Tk libraries. Make tcltklib.so which is required by Ruby/Tk. gcc -I. -I../.. -I../../. -I../.././ext/tk -DHAVE_RB_SAFE_LEVEL -DHAVE_RB_HASH_LOOKUP -DHAVE_RB_PROC_NEW -DHAVE_RB_OBJ_TAINT -DHAVE_ST_PTR -DHAVE_ST_LEN -DRUBY_VERSION=\"1.8.7\" -DRUBY_RELEASE_DATE=\"2012-02-08\" -D_XOPEN_SOURCE -D_DARWIN_C_SOURCE -DWITH_TCL_ENABLE_THREAD=0 -fno-common -g -O2 -pipe -fno-common -c stubs.c In file included from stubs.c:10: /usr/include/tk.h:78:23: error: X11/Xlib.h: No such file or directory In file…

Accepted Answer

try

```
rvm reinstall 1.8.7 --without-tcl --without-tk
```

but still your problem might to be related to gcc-4.2 -> it's required for MRI ruby, there are some successes with llvm/clang, but still it fails with `Fibers`
