[Cbc] Compiling and installing CBC with GLPK-4.47

Yes, I did this last night (Melbourne time) and it works out of the
box even with  -arch=x86_64 (i.e. compiling and installing). However,
I have not yet manage to run a mod file and data (i.e. AMPL or GMPL)
yet.

Any example that run with this syntax (ei.g. cbc
sample.mod$sample.dat) that you can share.

Stefan and Ted, what GMPL file and data did you use to test and says
that CBC with glpk-4.45 "works out of the box"?

Would it be possible to get a copy of the files?

I run configure without the OS X flag (i.e. -arch=x86_64), I got the
same problem. However, after sleeping the problem (I.e waking up this
morning), I think I figure what causing the problem. Andrew decided to
include zlib files by default in the 4.47 release. The coin glpk
library (i.e. libcoinglpk.a ) has problem with glp_zlib functions.

For example:

 "__glp_zlib_gzclose", referenced from:
      _z_fclose in libcoinglpk.a(glpenv07.o)

"__glp_zlib_gzputc", referenced from:
      _z_fputc in libcoinglpk.a(glpenv07.o)
  "_glp_main", referenced from:
      __glp_lpx_main in libcoinglpk.a(glplpx01.o)

The  -arch=x86_64 for Mac OS is not causing the problem. It is the
current scripts in coin glpk that is causing it. The zlib folder and
files are causing the problem as you can see in the errors.

I had similar problem in compiling x86 codes for ARM CPU / System
(i.e. iOS in iPhone) in Mac OS when creating Spatialtie library for
iOS.

Thanks.
