Intel fortran build error: intrinsic assignment error #9

Open glemieux opened 3 years ago

glemieux commented 3 years ago

When building a program with fhash as a dependency using fpm specifying ifort as the compiler I received the following error:

$ fpm build --compiler ifort

Thanks for reporting @glemieux; looks like I'm doing something non-standard here. I didn't get the same error as you reported, but I've put together a fix (see #10) that now seems to work with ifort 2021.1.2. Which version of ifort are you running?

If you get a chance, would you be able to trial the proposed fix in your fpm project:

[dependencies]
fhash = { git = "https://github.com/LKedward/fhash.git" , branch="fix-ambig-generic"}

Thanks for taking a look at this. I'm running ifort 17.0.1 20161005. The error still seems to be persisting, unfortunately.

Thanks, it looks like assignment to an allocatable polymorphic variable is not supported in your version of ifort (support was added in v18.0).

I can get the library compiling with ifort 17.0.1 if I replace these assignment statements with explicit allocation statements, unfortunately I then run into strange runtime errors with the tests and demos which I can only put down to a compiler bug.
