Installing specific version of the

[sskras]

I am trying to install gcc:

$ cygcheck -p bin/gcc
Found 10 matches for bin/gcc
gcc-core-10.2.0-1 - gcc-core: GNU Compiler Collection (C, OpenMP)
gcc-core-11.2.0-0 - gcc-core: GNU Compiler Collection (C, OpenMP)

gccmakedep-1.0.2-1 - gccmakedep: X Makefile dependency tool for GCC (installed binaries and support files)
gccmakedep-1.0.3-1 - gccmakedep: X Makefile dependency tool for GCC (installed binaries and support files)

So I try to put the whole name into command line:

$ apt-cyg install gcc-core-10.2.0-1 2>&1 | tail
gpg: Signature made Fri Dec 24 15:52:56 2021 EET using RSA key ID E2E56300
gpg: Good signature from "Cygwin <cygwin@cygwin.com>"
gpg: WARNING: This key is not certified with a trusted signature!

signature verified: setup.ini.sig
Updated setup.ini

Installing gcc-core-10.2.0-1
Package gcc-core-10.2.0-1 not found or ambiguous name, exiting

As the format seems to be wrong, I try another format -- now using = before the version:

$ apt-cyg install gcc-core=10.2.0-1 2>&1 | tail
gpg: Signature made Fri Dec 24 15:52:56 2021 EET using RSA key ID E2E56300

Updated setup.ini

Installing gcc-core=10.2.0-1
Package gcc-core=10.2.0-1 not found or ambiguous name, exiting

But it also fails.
Can this be fixed, please?

Now if I try pointing the latter format to the Cygwin installer:

$ Downloads/setup-x86_64.exe -P gcc-core=9.3.0-2
note: Hand installation over to elevated child process.

... it parses this fine and goes forward:

Thank you.
I had missed that the version selection feature has been implemented to the setup-x86_64.exe command line.

I'm sorry, but the current apt-cyg does not support the version selection feature.
However, setup-x86_64.exe has that feature, so the following subcommand can be a good alternative, until it is implemented to apt-cyg.

apt-cyg setup -- -nqBP gcc-core=9.3.0-2

Perhaps, I can prepare the fallback routine for using the version selection with above subcommand.

Thanks!
