This gcc5 package can be installed alongside Slackware's gcc-11
|
|
packages. These version 11 compilers can sometimes be quite a bit
|
|
more strict about what they accept as valid code. As a consequence,
|
|
you will regularly run into compilation issues with software. Not just
|
|
the software made with the scripts on slackbuilds.org, but also some
|
|
of the software in the Slackware core distribution requires patches in
|
|
order to get them to compile.
|
|
|
|
Still having the gcc version 5 compilers can sometimes be a lifesaver.
|
|
Particulars of the gcc5 package:
|
|
- The gcc5 binaries were given a suffix '-5' to make them stand apart
|
|
from Slackware's default compilers.
|
|
- The gcc5 package only contains the C, C++ and Java compilers.
|
|
- One all-encompassing package is built by the SlackBuild script.
|
|
- Profile scripts are added to /etc/profile.d/. You can 'source'
|
|
the profile script to prefer the gcc-5 compilers over gcc-7.
|
|
- On 64bit Slackware, the gcc5.SlackBuild will detect an existing gcc
|
|
multilib compiler and will then build a multilib capable gcc5.
|
|
If you run pure 64bit Slackware, then a pure 64bit gcc5 package is
|
|
built.
|
|
|
|
How to use these gcc5 compilers instead of Slackware's default ones?
|
|
Simple:
|
|
In your console or terminal, you 'source' the provided profile script,
|
|
like this (a c-shell compatible script is available as well):
|
|
|
|
source /etc/profile.d/gcc5.sh
|
|
|
|
The command 'source' is equivalent to the dot command ' . '.
|
|
The profile script will (re-)define the common variables that are
|
|
used by make and other programs to determine which binary to run as
|
|
the compiler:
|
|
|
|
export CC=gcc-5
|
|
export CPP=cpp-5
|
|
export CXX=g++-5
|
|
export AR=gcc-ar-5
|
|
export NM=gcc-nm-5
|
|
export RANLIB=gcc-ranlib-5
|
|
|
|
Nothing else needs to be done after sourcing the profile script.
|
|
All you do next is run your compile job as usual in that same console.
|
|
Your program will be compiled with the binaries provided by the gcc5
|
|
package.
