isn't that a case for the usual compiler - env - prepend-path workaround we've been using for years on several machines?

[AlexanderRichert-NOAA]

Yep

@AlexanderRichert-NOAA, what change is needed, how it was done before?

[AlexanderRichert-NOAA]

See for example discover and derecho's compilers.yaml, where for Intel, there's an LD_LIBRARY_PATH prepend_path setting, which uses a path ending with 'intel64_lin' (which contains libimf.so). @climbfuji do you remember if there's a reason we didn't also add it to extra_rpaths?

[climbfuji]

I don't remember. Presumably because it works ;-)

[AlexanderRichert-NOAA]

I also ran into an issue on gaea just now where it wants libfabric, even though it's a serial code. Seemingly relatedly, I can see -lmpifort_intel in the icc arguments, I'm not sure where it's coming from.

[climbfuji]

cray compiler wrappers maybe?
