This is one of the libraries that the gcc build system **could** build during the process of building the compiler.

But if your going to build more than one compiler, one time, its better just to build and install a copy.

Let the fun begin:

Spoiler:

The content of my pset.sh file:

export PATH=/opt/qemu111/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

From the location of the AL install:

core2quad system-image-armv6l $ . pset.sh
core2quad system-image-armv6l $ ./dev-environment.sh
  * * * *
  Type exit when done.

(And our release tab-ball:)

(the following properly closes the r/w hdb.img file system:)
(armv6l:1) home # cd /root
(armv6l:1) /root # umount /home
(armv6l:1) /root # exit
Restarting system.

This is another one that you "just dump" on top of /home.

Grumble: Three days later another application's configure told me I left the C++ interface out of the first gmp configuration.
That is simply not going to happen with the uClibc++ library in the emulator.

So this one is the "--without-cxx" library (again):
