Install gcc with cygwin on windows. I already did the annoying figuring out so you don't have to! Here, I'll show how to install gcc 9.2.0.
- Follow the first two steps from https://preshing.com/20141108/how-to-install-the-latest-gcc-on-windows/.
- In the cygwin64 folder, run the Cygwin.bat file.
!!! Cygwin automatically creates a folder in the "cygwin64/home" folder with your username. However, installation will fail if your username contains a space! To account for this, we want bash to open in a folder without a space. To do this, write the command:
echo "cd C:\cygwin64\home\USER_NAME_WITHOUT_SPACE" >> ~/.bashrc
Then run the Cygwin.bat file again.
- This will download gcc-9.2.0 files and unpack them, enter:
wget http://ftpmirror.gnu.org/gcc/gcc-9.2.0/gcc-9.2.0.tar.gz, .
tar xzf gcc-9.2.0.tar.gz
- To download prerequisites in the gcc-9.2.0 folder, enter:
cd gcc-9.2.0
.contrib/download_prerequisites
- to set current directory to where gcc needs to be installed, enter:
cd ..
mkdir objdir
cd objdir, .
- To create the makefile in objdir, but access the files in gcc-9.2.0 folder, enter:
../gcc-9.2.0/configure --prefix=C:/cygwin64/home/USER_NAME_WITHOUT_SPACE/gcc-9.2.0 --enable-languages=c,c++,fortran
- Finally, run the following and go outside and take a walk, because this will take a long time.
make -j 2 or 4 or 8, depending on which order of parallisation you want it to install
make install
--- Atm it's not yet installed lol
