hdf5 package installs but h5fc fails with ld: library not found for -lsz

[Michael-P-Allen (Mike Allen)]

Installing with sudo port install hdf5 succeeds (log file attached for reference). However the Fortran wrapper script h5fc provided by the package fails:

h5fc hello.f90 
ld: library not found for -lsz
collect2: error: ld returned 1 exit status

A workaround is to include -L/opt/local/lib/libaec/lib on the h5fc command line, but the wrapper script should handle this. The command line actually invoked by h5fc is

h5fc -show
/opt/local/bin/gfortran-mp-13 -pipe -Os -m64 -I/opt/local/include -L/opt/local/lib /opt/local/lib/libhdf5hl_fortran.a /opt/local/lib/libhdf5_hl.a /opt/local/lib/libhdf5_fortran.a /opt/local/lib/libhdf5.a -Wl,-headerpad_max_install_names -Wl,-syslibroot,/Library/Developer/CommandLineTools/SDKs/MacOSX14.sdk -lsz -lz -ldl -lm

and the sz library located in opt/local/lib/libaec/lib is not found. This is not the case for h5cc and h5c++ wrapper scripts, for which the path to the library is given explicitly, as shown by

h5cc -show
/usr/bin/clang -isysroot/Library/Developer/CommandLineTools/SDKs/MacOSX14.sdk -pipe -Os -isysroot/Library/Developer/CommandLineTools/SDKs/MacOSX14.sdk -L/opt/local/lib /opt/local/lib/libhdf5_hl.a /opt/local/lib/libhdf5.a -Wl,-headerpad_max_install_names -Wl,-syslibroot,/Library/Developer/CommandLineTools/SDKs/MacOSX14.sdk /opt/local/lib/libaec/lib/libsz.dylib /opt/local/lib/libz.dylib -ldl -lm

There appears to be something in the post-destroot section of the Portfile which sets up /opt/local/lib/libaec/lib/libsz.dylib for h5c++ and h5cc, but nothing similar for h5fc. However I'm not a Portfile expert.

Replying to Michael-P-Allen:

ld: library not found for -lsz

This is a problem we've had with other ports: #67508. Maybe we didn't fix it everywhere…
