GCC Development Snapshots

Hi everyone,

I recently started building slackware packages for the development snapshots of gcc, and thought I'd share them with you.

gcc developers typically release a new snapshop about once a week. I grab them, build them, and package them up so I can test out new C++17 features.

They can be found here: http://janus.bryanstamour.com/gcc-snapshots/

If you do end up downloading and playing with one, let me know how it works for you!

nice, thanks, but I am unsure that it is a good idea to put this to /usr/local and overlay the existing environment
might make it difficult to install packages via sbo

I personal prefer installing trial gcc versions into a custom folder, and have a script to activate it.
so I can test it, but keep a clean system

on a old RHEL 6 32 bit I use this for building

Code:

GCCVERSION=6.3.0

../configure          \
    --prefix=$HOME/local/opt/gcc-$GCCVERSION          \
    --libdir=$HOME/local/opt/gcc-$GCCVERSION/lib      \
    --enable-lto                \
    --disable-nls               \
    --enable-languages=c,c++

make -j$(nproc) && make install

and this for activation of the gcc envrionment

Code:

GCCVERSION=6.3.0

export GCCDIR=$HOME/local/opt/gcc-$GCCVERSION

export LIBDIR=$GCCDIR/lib:/usr/local/lib
export PATH=$GCCDIR/bin:$PATH
export LD_LIBRARY_PATH=$LIBDIR
export C_INCLUDE_PATH=$GCCDIR/include
export CXX_INCLUDE_PATH=$GCCDIR/include/c++/$GCCVERSION

export CC=$GCCDIR/bin/i686-pc-linux-gnu-gcc
export CXX=$GCCDIR/bin/i686-pc-linux-gnu-g++

doing so makes it easy to test several gcc versions in different configurations on 1 system.

maybe you want to put something this in your build? than I don't need to build it self anymore,

Hrm, good ideas. I think I'll work that into my build script so the packages can be installed concurrently. Thanks for the pointer!

I fixed up my build script to put each compiler version into its own directory under /opt, so you can have multiple versions at the same time. I am rebuilding all of my packages now, but the one that is up there now (gcc-7-20170115) should be fine to play around with.

Thanks again for the tips, and if you do end up using my packages, please let me know how you find them!
