Trouble compliling

[51Ford]

Hi, I'm trying to compile the MS2 3.4.3 code as a first step toward trying some modifications. I have cygwin 32 bit installed as well as the 2012 version of the msextra build tools. Everything seems to work fine until I get this "fatal error in a forked process". Can anyone please offer a suggestion?

$ make ms2
make make_megasquirt2

So I tried an alternative method using VirtualBox and Linux Mint. I’m able to unpack the 2012 tools into usr bin etc using tar from the terminal, but make ms2 seems unable to find c usr bin m68hc11-elf-gcc even though I can clearly see the file in the directory. The error says no such file in c:/usr/bin. Do I need to change something in makefile because it is a virtual machine not starting w c?

In Unix/Linux there's no such thing as "C:"
Your tools should be in /usr/bin or /usr/local/bin

Thanks for the reply James. I got it working yesterday with the following command:

LANG=C sudo apt-get install ia32-libs

This apparently installs the needed ia32 libraries to run the compiler. Interestingly there was still a message in the output of 'make ms2' about no 'c:/usr/bin/m68hc11-elf-gcc' but it was clearly running /usr/bin/m68hc11-elf-gcc and made a function s19 file.

Ah.. I think the Makefile always checks in C:/..... (reports an error) and then tries the other paths.
