Is there a way to specify the GCC version i would like to install?
I only get the latest version if i install it that way:
pacman -S mingw-w64-x86_64-gcc
You can find a few older versions of GCC here:
http://repo.msys2.org/mingw/x86_64/
You can download them with wget and install them with pacman -U filename if I recall correctly. Note that using old packages in this way is a process prone to error because the packages might depend on older versions of their dependencies, which you would also have to install. Also, when you run pacman -Syu it would try to upgrade your GCC to the latest version.
You might be better off building the older versions of GCC yourself and installing them with a different name so they don't conflict with the MSYS2 packages.

I need to use gcc-arm-linux-gnueabi version 6.5, along with a version of libc that came out around the same period (I believe is libc-2.26). My host system is Ubuntu 18.04.
If I go with just a simple
sudo apt-get install gcc-arm-linux-gnueabi g++-arm-linux-gnueabi binutils-arm-linux-gnueabi
I'll get v7 for the gcc cross compiler and v2.30 for binutills, which does not work for me, since I'll end up with errors similar to the one described here.
If I try to download the deb packages, I get unmet dependencies.
I have also tried to force apt-get to install specific versions, using something like described here but I get error messages that the version I'm looking for cannot be found.
Is there a way to force ubuntu to install specific (older) version of gcc, libc, etc.?
I know that gcc v 6 is obsolete, but I cannot do otherwise.
You could give a try to the Linaro release of gcc 6.5, available here, which comes with glibc version 2.23.
I am using Bellhop ray tracing algorithm for MacOS. I have downloaded the source code for MacOS without the binaries.
I want to change my gfortran version from 9.2.0 to 8.3.0.
I installed it using homebrew. I have version 9.2.0 installed. I have it installed at /usr/bin/
I cannot seem to find any commands online to change the version.
gfortran -dumpversion
This gave me my version number but I cannot seem to find a command to get a different version.
I am working on macOS (Mojave V 10.14.6). I installed it using homebrew in /usr/local/bin/gfortran. I have version 9.2.0 installed.
type gfortran
Gives me the output:
/usr/local/bin/gfortran
Update: I believe I have 8.3.0 now downloaded by erasing 9.2.0 and downloading gfortran-8. I needed to completely remove it from my system before downloading a different version.
I'm trying to build a binary from source code which has a dependency on the package" NASM 2.12.02 or later. However, I have an earlier version already installed on my Mac via Xcode:
/usr/local/bin/nasm -v
NASM version 0.98.40 (Apple Computer, Inc. build 11) compiled on May 1 2018
So to (attempt to) rectify this, I used Homebrew to install a much newer version of the package
brew info nasm
nasm: stable 2.13.03 (bottled), HEAD
However, now my PATH is only pointed to the old NASM executable, while the new tool seems to be sitting in Homebrew's Cellar (ie. /usr/local/Cellar/nasm/2.13.03).
Is there a nice way of "switching" between these versions so that the system PATH views only the newer version and disregards the older one? So far I've thought of rm -rf-ing the old version and exporting the new version to my PATH, but that seems very destructive.
Also, I have run the command: brew doctor and have resolved all linker errors, but that has not seemed to help.
Any help would be greatly appreciated!
To fix this, I used the following command:
export PATH=/usr/local/Cellar/nasm/2.13.03/bin:$PATH
This modifies the PATH variable to point to the /usr/local/Cellar/nasm/2.13.03/bin directory and find the nasm executable there before looking in /usr/local/bin.
I need to use/integrate GCC 5.X (in my case 5.3, and it is already installed) on Xcode 6.2.
I've found a lot of outdated tutorials about GCC 4.X and Xcode 5 (or lower), but all of them are outdated and do not work anymore.
I've also found this tutorial, but I have not the 5.3.xcplugin file that the tuto recommend to copy.
I am still on Mac OS X Maverick, and I can install Xcode 7 if necessary.
Anybody would know how to do it?
MacPorts still has an installer for Mavericks. It will likely add /opt/local/bin:/opt/local/sbin to your $PATH in .profile, or whatever shell startup file you use, and leave a backup of the old file you can probably get rid of once you're satisfied.
I would suggest upgrading to the latest Xcode release - and to El Capitan unless you have some specific reason not to. AFAIK, if you can run Mavericks, you can run the latter. I will avoid any arguments about the merits of Brew vs. MacPorts here. There's plenty of documentation on the MacPorts pages.
Make sure the package database is up to date:
sudo port -v selfupdate`
Have a look at the existing gcc ports:
port list | grep gcc
note: you might as well install the stable gcc6 (6.1.0) package.
Install the package - this may also install dependency packages:
sudo port install gcc6 [-universal]
This may take a while, as it might need to build from source. For most packages, the -universal flag says that you don't care about 32-bit (IA32) builds, etc.
You can see various package versions with port select ... options, e.g.,
port select --list gcc
And enable the installed gcc:
sudo port select --set gcc mp-gcc6
You may need to rehash so the shell adds the new binaries to its search. Or just start a new shell. gcc -v should yield something like:
gcc version 6.1.0 (MacPorts gcc6 6.1.0_0)
I am on Solaris 11 environment and gcc-3.4.6 is installed on it. The problem is that I am not able to compile exe's there, The error is
-sh: gcc: gcc: cannot execute [Invalid argument]
even if I write gcc only it gives the same error. Kindly help.
Unlike in Solaris 10, on Solaris 11 the GCC is not installed by default.
Fear not.
By far the easiest is to use IPS to install it using the commands below (while being root or other superuser):
pkg install pkg://solaris/developer/build/gnu-make
pkg install pkg://solaris/developer/build/make
pkg install pkg://solaris/developer/gcc-45
pkg install pkg://solaris/system/header
pkg install pkg://solaris/developer/build/autoconf
pkg install pkg://solaris/developer/build/automake-110
This will give you all the tools you typically need to build various open source software packages.
Note that some of the packages have a version number in the package name itself, e.g. gcc-45. You may be able to find even later versions in the package repository, for example for Solaris 11.2 Beta you'll find you have a choice of GCC 4.5, 4.7 or 4.8. The same applies to automake which is now also available in v1.11.
