gcc_dev_FIXUPHACK does not create cc and gcc links with Ubuntu gcc-10

[peabee]

In Ubuntu builds with gcc-10
/packages-templates/gcc_dev_FIXUPHACK
does not create the necessary cc and gcc links......

[peabee]

Lots of other links also not created..........

If it's focal, then the gcc package depends gcc 9.x, not 10.x. If you use the gcc package, which symlinks /usr/bin/gcc to gcc-9, you'll have to replace the symlink. Technically, you're not supposed to change the default GCC version to something different than the version used to build packages in focal, because you might run into some incompatibility.

And if you're not sure if this is caused by missing dependencies, you can do this:

yes|gcc_dev|gcc-10|exe>dev,dev,doc,nls||deps:yes

[peabee]

gcc_dev_FIXUPHACK should create the correct symlinks.......

DISTRO_PKGS_SPECS-ubuntu-focal has:
yes|gcc_dev|gcc-10-base,gcc,gcc-10,g++,g++-10,cpp,cpp-10|exe>dev,dev,doc,nls

Packages-ubuntu-focal-main has:
gcc-10-base_10.3.0|gcc-10-base|10.3.0|1ubuntu1|BuildingBlock|265K|pool/main/g/gcc-10|gcc-10-base_10.3.0-1ubuntu1~20.04_i386.deb||GCC the GNU Compiler Collection base package|ubuntu|focal|

so gcc-10 is a valid focal option............

[peabee]

OK - 2 problems.........
My DISTRO_PKGS_SPECS-ubuntu-focal has:
yes|gcc_dev|gcc-10-base,gcc,gcc-10,g++,g++-10,cpp,cpp-10|exe>dev,dev,doc,nls
which is wrong should be:
yes|gcc_dev|gcc-10-base,gcc-10,g++-10,cpp-10|exe>dev,dev,doc,nls

but there is also 2 * missing from gcc_dev_FIXUPHACK
which I will correct

[dimkr]

so gcc-10 is a valid focal option............

It's a valid option, but not the default. gcc points to gcc-9 because that's the default.

The /usr/bin/gcc symlink comes from the gcc package, which depends on gcc-9 and not on gcc-10.
