Compile error when using "xc16plusplus_only.sh linux" about xc16plusplus HOT 2 CLOSED

Hi! It fails to proceed because you are on a 64 bit system: the script wants to build a 32 bit compiler and expects to run a on 32-bit system (in other words, it is not designed to cross-compile the compiler).

There are three approaches you might want to follow:

1. Compile on a 32-bit debian system/virtual machine/chroot - I've just tested and it compiles fine on a Debian Stretch 32-bit VM(*); then copy the resulting executables to your 64-bit system;
2. Try to build a native 64-bit compiler executable;
3. Try to cross-compile a 32-bit compiler on your 64-bit system (you will need g++-multilib libc6-dev-i386 and a lot of patience to cope with the build errors).

The first approach is what I do for the binaries I release: I compile on a fedora-22-i386 chroot inside a 64-bit system.

To be honest when i wrote the script I chose not to consider the second option at all, given that Microchip's other executables are 32-bit anyway.

The third option would be interesting, I tried to make it work in the past but I gave up because some configure commands seemed to ignore me and stubbornly built 64-bit libraries. If you manage to do it, I will be happy to accept your patch!

(*) = All I had to do was to replace #!/bin/sh with #!/bin/bash in xc16plusplus_only.sh and install packages build-essential bison flex m4.

@fabio-d : Thank you for clarifying what was causing the error and for suggested workarounds!
