Hey os161 team 👋🏼
I am not able to install the os161-toolchain using apt on my Ubuntu 18.04 system. I have manually added the launchpad PPA links to my sources.list.d.
I am getting this error

sources.list.d

@yasht01 git clone https://gist.github.com/9825913.git then run the script :)

Trying to install gcc-mips-linux-os161 directly shows the issue is due to the dependency on libmpfr4, but only libmpfr6 is available. Instead of compiling everything from source, as the script suggested above does, a simpler option is to compile from source only gcc ad then install the rest as usual. I used the following:

sudo apt build-dep gcc-mips-linux-os161
sudo apt install binutils dpkg-dev devscripts
apt source gcc-mips-linux-os161
cd gcc-mips-linux-os161-4.8.3~os161~2.1~xenial0
debuild
cd ..
sudo dpkg -i gcc-mips-linux-os161_4.8.3~os161~2.1~xenial0_amd64.deb
sudo apt install os161-toolchain
