[GAP Forum] Having trouble installing GAP 4.7.8

[Will Chen]

I'm running OS X Yosemite on a 2013 Macbook Pro, and I've tried installing
gap 4.7.8 in two ways:

1. I downloaded the gap4r7p8_2015_06_09-20_27.tar file from here:
http://www.gap-system.org/Releases/index.html
Then I unpacked it, and in the resulting gap4r7 directory I entered
"./configure; make"

The configure seemed to go through without trouble. Make however ended
in...:

make[1]: *** [gmp_build] Error 1

make: *** [extern] Error 2


I don't understand the error. I've installed XCode, which seems to already
be packaged with the apple command line tools.


2. I tried using BOB, following the directions here:
http://gap-system.github.io/bob/#downloadtab

including installing MacPorts and entering "sudo port install readline
+universal ncurses +universal gawk wget xorg-libX11 xorg-libXaw" in the
terminal.

That seemed to go through fine, until I actually open Bob, at which point I
get the error message in the terminal:

I've tried redownloading Bob to no avail.

Any ideas?
