[GAP Forum] Installing "io" package on Mac OS X

[Max Neunhoeffer]

Dear Forum,

this problem has already been fixed in the development version of GAP.

The following fix for GAP 4.4.12 seems to work on all versions of
MacOSX (contrary to the one suggested by Dima):

After GAP itself was built, edit
  gap4r4/bin/i686-apple-darwin10.4.0-gcc/gac
  (or similar, depending on your version of OSX)

in line 78 from

  c_dyn_linker="ld"

to

  c_dyn_linker="gcc"

Then try
  ./configure ; make

in gap4r4/pkg/io again.

Best regards,
  Max.
