Hello Bernard,
I did a clean, from-scratch compilation after copying that 18.2.0 Darwin architecture file to 18.6.0.
Sadly, no change. Still fails at link time with all the "Undefined _H5xxxx" errors.
Ok. Since it starts with at "_" I almost suspected it may be some Fortran binding but then it is being called from C++ code.
My own test is still compiling (slow VM).
Could you include the output of:
* sudo port installed * uname -a
I have included my own output to give you an idea of what I am looking for (note that I cannot tell yet if compiling in my VM will encounter the same error you see).
Yours, Roland
