Topic: [gcc] PKGBUILDs for newer versions

Hello you all,

within the last weeks I was busy creating further newer PKGBUILD-files for the newer gcc-multilib suite and named packages. So first of I'd like to thank Luke as I've used the files as examples. Attention therefore: You should use them incremental, so if you want version 9.3.0 on your system you'll need the previous version for building. Same with this one to repeat!

Human being in favor with clear principles and so also for freedom in soft- and hardware!

Certainly anyone who has the power to make you believe absurdities has the power to make you commit injustices: For a life of every being full with peace and kindness, including diversity and freedom. Capitalism is destroying our minds, the planet itself and the universe in the end!

This can be built with gcc-multilib 6.3 we already have within the repositories!

Certainly anyone who has the power to make you believe absurdities has the power to make you commit injustices: For a life of every being full with peace and kindness, including diversity and freedom. Capitalism is destroying our minds, the planet itself and the universe in the end!

Human being in favor with clear principles and so also for freedom in soft- and hardware!

Certainly anyone who has the power to make you believe absurdities has the power to make you commit injustices: For a life of every being full with peace and kindness, including diversity and freedom. Capitalism is destroying our minds, the planet itself and the universe in the end!

NOTE; You need a newer version of glibc for sure to finalize the compilation. Looking here for the concurrent PKGBUILD for version 2.27!

Human being in favor with clear principles and so also for freedom in soft- and hardware!

Certainly anyone who has the power to make you believe absurdities has the power to make you commit injustices: For a life of every being full with peace and kindness, including diversity and freedom. Capitalism is destroying our minds, the planet itself and the universe in the end!
