Support for Irix was removed from gcc, this project brings it back.

The following compiler builds are supported:

• Irix 5.3 - ABI O32
• Irix 6.2 - ABI O32/N32
• Irix 6.2 - ABI N32/O32
• Irix 6.5 - ABI N32/O32/N64

Getting the sources

Use git-lfs to clone the repository:

git-lfs clone git@github.com:pdaxrom/irix-gcc.git

Docker

For simple build use docker:

bash build-docker.sh

This will create a docker image with cross-compilers and archives with native ones for deployment on SGI machines for Irix 5.3 - 6.2 ABI O32/N32 and Irix 6.5 ABI N32/64/32.

Copy the required archive to the machine and unpack it in the root directory. The path to the o32 compiler is - /opt/irix-gcc-o32/bin, to the n32 - /opt/irix-gcc-n32/bin.

Ubuntu

To build on Ubuntu install the following dependencies:

apt install -y build-essential texinfo autoconf2.69 wget mc libtool autopoint

Run cross compiler build:

bash build-cross-irix-gcc.sh

By default, it installing to /opt/irix-gcc-o32-cross. The path can be changed in config.inc (TARGET_INST).

Once the cross compiler is built, you can build the native version:

bash build-irix-gcc.sh

It installing to /opt/irix-gcc-o32. Once built, you can transfer it to SGI machine.

To build for ABI N32, use config-n32.inc for Irix 6.2 or config-irix65.inc for Irix 6.5:

bash build-cross-irix-gcc.sh config-irix65.inc

and

bash build-irix-gcc.sh config-irix65.inc
