Re: [MACTCL] Can't find install directory properly on OS X.

[Christopher S. M. <morrison@ARL.ARMY.MIL>]

I FOUND IT!  Jeesh.  I finally figured out what was the problem from my
flailing 8.3.2 build/install.  To recap, I was basically getting a runtime
error from Tcl_Init, Itcl_init, ... all saying that they couldn't find
their tcl initialization files (that are in the install directory). 

The problem didn't have to do with the fact that I was munging the
Makefiles to install into a different place.  The problem had to do with
the existing /usr/lib/libtcl83.dylib that I had laying around getting
linked instead of the newly built one (/usr/brlcad/lib/libtcl8.3.a).

That problem may seem obvious except for the fact that there was an
explicit -Lwhatever -ltcl8.3 on the compile line, yet the library in
/usr/lib was still used!  I find this quite contrary to what should be
happening, and if anyone has any clues, please send them my way.  Here is
the final compile line for building libtcl and tclsh:

-L/Users/sean/brlcad6/.libtcl8.3.pmac -ltcl8.3  -lc \
         -o tclsh
/usr/bin/ld: warning unused multiple definitions of symbol _matherr
/Users/sean/brlcad6/.libtcl8.3.pmac/libtcl8.3.a(tclMtherr.o) definition of
_matherr in section (__TEXT,__text)
/usr/lib/libc.dylib(s_matherr.o) unused definition of _matherr

Well, the simple solution was to move/remove the tcl dylib in /usr/lib and
all was fine (except for that nasty warning shown above from the .a
getting created without the multiple define suppression turned on).  Well,
back to proper coding now..

Cheers!
