Okay, it passes non-existing flag, -ObjC:

It's right there in cmake/modules/aqt.cmake:

    set(aqt_COMPILE_FLAGS "-ObjC")

Ah, this: reinplace "s|-ObjC|-ObjC -framework AquaTerm|" ${worksrcpath}/cmake/modules/aqt.cmake.

You can see that this reinplace does not add the -ObjC flag; it adds the -framework AquaTerm flag after the existing -ObjC flag.

What do you mean by "fixing flags"? If you mean removing -ObjC, I expect that is what caused this error. @class is Objective-C syntax. The compiler needs to be told to compile in Objective-C mode, which is presumably what the -ObjC flag was accomplishing.

Well, obviously a flag not supported by GCC must not be used with GCC. So flags are wrong. If GCC cannot compile the port, it should be blacklisted, or if only one module fails, it should be disabled, assuming a fix to the syntax is bothersome to come up with.

[barracuda156]

Replying to ryandesign:

UPD. It is still we are breaking it, but I pointed to a wrong place. This is the problem:

if {${os.platform} eq "darwin"} {
    default_variants    +aquaterm
}

This should be conditional on Clang used, and likely the port is fixed.

What makes you think this flag is specific to clang? The flag was added to plplot in 2006 before clang existed.
