Re: [MACTCL] Bug with tcl configure command - wrong compiler used

[Scott R. <sco...@sb...>]

This sounds like an issue with configure and/or the makefile.

I haven't built on MacOS yet, but looking at the configure scripts and makefiles for 8.6.6, it seems there is an extra call to configure that happens when you run "make" in the macosx directory to re-run configure in the unix directory, which is then used to build.  Not clear that this step is passing the CC variable down into the unix directory's configure when it does that.

Try doing:
     CC=gcc-5 make

 I
 was using TigerBrew. This problem was discovered when I was
 not  
 using the package manager. I was
 building using the "configure ;  
 make
 ; make install" way.
