I bought a Dell PowerEdge T430, which has no graphics cards, and installed an old Nvidia 6200 TurboCache card on it.
It is recognized in the lspci | grep VGA command, but the drivers are not intalled.

I did download them, login in the runlevel 3 (telinit 3), and run the install script.
Just before the installation starts, the script tells me the following:
CC Version check failed, the gcc version used to compile the kernel (7.4) is not the same as the current gcc version (7.5) When I run gcc --version it turns out I have the 7.5 version installed.

I ran across Internet and could not find a way to downgrade my GCC version.

How can I to go GCC version 7.4 for the sake of this driver install ?

Easiest is maybe build from sources:

  • Get GCC sources, download and unpack or via git somewhere to srcdir in HOME or so.

  • Get the prerequisites:

    cd $srcdir
./contrib/download_prerequisites

  • Make a build directory builddir somewhere outside of srcdir.

  • Configure GCC in builddir:

    cd $builddir
$srcdir/configure --prefix=$installdir --disable-bootstrap --disable-nls

    • You can install it in installdir somewhere in your HOME or wherever. In general you do not want to replace the system GCC.

    • If you prefer a real bootstrap (3-stage build) then ditch --disable-bootstrap

    • If you only need some languages, then --enable-languages=c,c++ etc.

    • If you prefer funny diagnostics in native language, ditch --disable-nls.

  • Make GCC:

    cd $builddir
make
  • Install GCC: 
    cd $builddir
make install

Now you have a gcc and gcc-7.4 something in $(installdir)/bin/

At your option,

  • You can soft-link $HOME/bin/gcc to $(installdir)/bin/gcc, similar for g++ and the other compilers if you need them. $HOME/bin must be prior to system paths.

  • Something like export PATH="$(installdir)/bin:$PATH" in the shell where you want to use it in favor of system gcc.
