There is nothing in py-tifffile that asks for a specific compiler.

However, I get the same error when trying to do port info py39-numpy.

comment:2 Changed 4 years ago by ryandesign (Ryan Carsten Schmidt)

Owner: changed from Schamschula to michaelld
Port: py-numpy added; py-tifffile removed
Summary: py-tifffile: Compiler clang37 not available for Darwin20 armpy-numpy: Compiler clang37 not available for Darwin20 arm

Right, sorry.

It seems really inconvenient that each port needs to check which platform it's on and only ask for compilers that are supported on that platform. Couldn't that be handled by the portgroup?

comment:4 Changed 4 years ago by cjones051073 (Chris Jones)

The port group now issues a warning if a port asks to remove an already not available compiler, but still considers a port asking for one a hard error

https://github.com/macports/macports-ports/blob/f9f395ba65eb4a15eb41dcbaf4a91b74ef8559be/_resources/port1.0/group/compilers-1.0.tcl#L644

Sure, this could be changed, but what should the PG do ? In this case the port is only asking for one, rather old, compiler, so I dont really see what can be done. I think in this case the port also needs to be updated a bit.

Thinking about it, the only way I see to do this is to remove from ports like this the explicit requesting of a compiler variant, and instead only list those they don't want. Then the PG can figure out for itself what the remaining set of compilers are for a given platform.

Now py27-scipy is failing in a really strange and problematic way: https://build.macports.org/builders/ports-11_arm64-watcher/builds/3877/steps/subports/logs/stdio

It doesn't fail to mportopen, but then a variable that should always be set, isn't.

comment:8 Changed 4 years ago by cjones051073 (Chris Jones)

Its probably this

Warning: port "py27-scipy" failed to open: Compiler clang37 not available for Darwin20 arm

The port also explicitly adds the clang37 compiler to the list, so I guess it needs removing there as well.

Removing clang37 is all very well, but it's still a real problem that this code can break a port that badly.

I would argue all the change has done is expose an issue that was already there, namely declaring variants for compilers which could never have worked on a number of platforms. This issue isn’t jsut for arm, its also there for intel, just that we haven’t yet cleaned up the list there.

As i said, we could decide to make requesting to add a compiler variant a warning and not a hard error as it still is. That would be trivial to do, I am just not sure its the right thing to do.
