[xylar]

This is a test PR to see whether the test that @gillins added in #233 passes for 1.14.4

@gillins, osx-64 is passing here, too. So I don't think we have an explanation for why kealib is failing in conda-forge/kealib-feedstock#65

[gillins]

Sigh. Thanks @xylar. @petebunting any chance you'll have some time to look into this some more?

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.

Suggested change

	$CXX ${CXXFLAGS} $RECIPE_DIR/testhdf5exc.cpp -o testhdf5exc -L$PREFIX/lib -lhdf5_cpp -lhdf5 -I$PREFIX/include
	${CXX} ${CXXFLAGS} ${LDFLAGS} $RECIPE_DIR/testhdf5exc.cpp -o testhdf5exc -lhdf5_cpp -lhdf5 -I$PREFIX/include

You can also follow the style and add the test to the test section:

[xylar]

Agreed, I will move it if we decide we want to keep the test.

[gillins]

Update: valgrind shows no errors running the kealib test on Linux x86_64 with hdf5-1.14, so nothing useful there....

[xylar]

@gillins, no surprise. The issue seems to be specific to clang. My understanding based on some googling is that it's related to mixing up the system vs. the conda-forge (or in my google searches the homebrew) version of a core c++ library (can't recall which). Anyway, seems both osx and clang specific.

[gillins]

Ah ok, so might be a problem for other packages too? Unfortunately I no longer have a Mac to run other tests...

[xylar]

I'm going to close this as I don't think it was helpful.
