[zoq]

Thanks for the report, looking into it.

Hmm, I wonder if it is just because getline is missing on macOS < 10.7, and is used in the next test after ReportCallbackTest (provided the sequence is identical across platforms: on Sonoma all tests run, though one case fails):

ensmallen/tests/callbacks_test.cpp

Line 818 in 5bb9fac

while (std::getline(stream, line, '\n'))

I will check this out.

UPD. Please ignore malloc errors, that happens due to a peculiarity of the old macOS, where there are two libstdc++, when a modern GCC gets installed. I have added a fix now, and those errors are gone.

[barracuda156]

@zoq No, we do not need getline in the SDK, apparently. Solving malloc issue somehow fixed the initial failure (which was occurring consistently otherwise, I reran tests a few times). I have no idea why :)

We do not need to merge a fix for malloc issue, it is perhaps too much of a hassle, unless you know a neater way to do it. What fixes it is adding a wrapper which sets DYLD_LIBRARY_PATH to the location of GCC libraries, so that its libstdc++ is found prior to the one sitting in system prefix:

    pre-test {
        if {${os.platform} eq "darwin" && ${configure.cxx_stdlib} ne "libc++"} {
            move    ${cmake.build_dir}/ensmallen_tests \
                    ${cmake.build_dir}/ensmallen_tests-orig

            set  wrapper    [open "${cmake.build_dir}/ensmallen_tests" w 0755]
            puts ${wrapper} "#!/bin/bash"
            puts ${wrapper} ""
            puts ${wrapper} {if [ -n "$DYLD_LIBRARY_PATH" ]; then}
            puts ${wrapper} "   DYLD_LIBRARY_PATH=${prefix}/lib/libgcc:\${DYLD_LIBRARY_PATH}"
            puts ${wrapper} {else}
            puts ${wrapper} "   DYLD_LIBRARY_PATH=${prefix}/lib/libgcc"
            puts ${wrapper} {fi}
            puts ${wrapper} {export DYLD_LIBRARY_PATH}
            puts ${wrapper} ""
            puts ${wrapper} {exec "${0}-orig" "$@"}
            close $wrapper
        }
    }

(This is only needed when GCC is used with libstdc++; it is arch-agnostic, but typically happens on PowerPC, since there we only have GCC, and libc++ is not yet functional.)

So yeah, PowerPC is all good :)

[zoq]

Awesome, thanks for diving deeper into the issue.

[barracuda156]

@zoq I gonna close this one, since the issue is not on ensmallen side, and I have fixed it for Macports.
Sorry for a hassle, but maybe it helps someone later who gonna try this without Macports.
