Specifying package version in command line of setup

Specifying package version in command line of setup

[Alexey Sokolov]

Hi

When gcc-5 was uploaded (as test), gcc-4 broke:

C:/cygwin-root/lib/gcc/i686-pc-cygwin/4.9.3/cc1plus.exe: error while
loading shared libraries: cygisl-10.dll: cannot open shared object file:
No such file or directory

I'm using this to install cygwin:
setup-x86.exe --quiet-mode ... --packages automake,gcc-g++,...

But it installs gcc-4, because gcc-5 is marked as test version.

Is there some way to specify on command line:
* which version of which package I want to install,
* or to enable installation of test versions?

You can not have gcc-4 and ggc-5 installed at the same time with
setup.

not that I am aware of.

Ah, that helped, thanks. This dependency is missing from gcc-4 though.

Yes, sure, I didn't try to install both at the same time. I wanted to
install some version which is working. Gcc-4 didn't run due to error
above, and I didn't find a way to install gcc-5 without GUI.

I thought that it's related to gcc-5 because of
https://cygwin.com/ml/cygwin/2015-09/msg00282.html
And before upload of gcc-5 to the archive, gcc-4 was working fine when
installed this way (just gcc-g++, without explicit libisl10)

This would enable me to install gcc-5, which is another way to
workaround problem of a non-working gcc-4. Such features would be useful
in other situations too.

I think the problem is that when JonY uploaded gcc-5, he inadvertently 
changed the dependencies of the gcc packages to those of gcc-5. 
Probably those packages should require the dependencies of both gcc-4 
and gcc-5.
