Why haven't gcc10 and clang10 been added as compilers for ports?

[gaming-hacker (G Alexander)]

Hello,

It looks like this was pulled into main branch

​https://github.com/macports/macports-base/pull/171

but if I do a search on openmpi versions available, I get

for gcc

openmpi-gcc5	4.0.1	science parallel net	A High Performance Message Passing Library
openmpi-gcc6	4.0.1	science parallel net	A High Performance Message Passing Library
openmpi-gcc7	4.0.1	science parallel net	A High Performance Message Passing Library
openmpi-gcc8	4.0.1	science parallel net	A High Performance Message Passing Library
openmpi-gcc9	4.0.1	science parallel net	A High Performance Message Passing Library

and for clang

openmpi-clang	4.0.1	science parallel net	A High Performance Message Passing Library
openmpi-clang37	4.0.1	science parallel net	A High Performance Message Passing Library
openmpi-clang50	4.0.1	science parallel net	A High Performance Message Passing Library
openmpi-clang60	4.0.1	science parallel net	A High Performance Message Passing Library
openmpi-clang70	4.0.1	science parallel net	A High Performance Message Passing Library
openmpi-clang80	4.0.1	science parallel net	A High Performance Message Passing Library
openmpi-clang90	4.0.1	science parallel net	A High Performance Message Passing Library

Is there a reason why clang_compilers.tcl haven't been updated?

The same is for port 'mpich'

clang

mpich-clang50	3.3.2	science parallel net	Message Passing Interface (MPI) Library
mpich-clang60	3.3.2	science parallel net	Message Passing Interface (MPI) Library
mpich-clang70	3.3.2	science parallel net	Message Passing Interface (MPI) Library
mpich-clang80	3.3.2	science parallel net	Message Passing Interface (MPI) Library
mpich-clang90	3.3.2	science parallel net	Message Passing Interface (MPI) Library

gcc

mpich-gcc5	3.3.2	science parallel net	Message Passing Interface (MPI) Library
mpich-gcc6	3.3.2	science parallel net	Message Passing Interface (MPI) Library
mpich-gcc7	3.3.2	science parallel net	Message Passing Interface (MPI) Library
mpich-gcc8	3.3.2	science parallel net	Message Passing Interface (MPI) Library

The PR you're referring to is for MacPorts base but there has not yet been a new release of MacPorts base since that PR was merged. We probably need to wait until we have released a new MacPorts base containing that change before we could make any changes to the ports tree that require that base change.

In the meantime, if you did want to use one of the newer clang versions to build something, you can use it manually using sudo port select to select the version of clang you would like to use. As you probably know, port select --list clang will give you a list of the available options.

Then to use that version of clang to build a certain port you would force it manually on the command line like this:

sudo port -v install MyFavouritePort configure.compiler=macports-clang

I am not sure if there's any way that that mechanism can be used with the openmpi ports, though.

This isn't really an error in the clang port, and there's nothing about clang-10 that needs to be fixed, but I guess we'll leave this ticket open in case somebody else stumbles across it, pending a new base being released.

Besides it makes me feel better to see tickets attached to ports that I am working with when I log into the system. Sense of belonging and all that.

mpich gcc10 support was added in [34bc752a538068e3f10187f8e5035491cb75e7e9/macports-ports].
