Need help with usage of this library about h5fortran

[scivision]

It might be a slight typo

gfortran test_array.f90 -I include/ -L lib/ -llibh5fortran.a

That did not work. But I am little bit confuse from your comment as I knew, to give filename to the linker utility you have to pass the file name as -l:filename where as to link library you have to pass -lnamespec. So, either -l:libh5fortran.a or -lh5fortran would be a valid optioin. Manual page of GNU Linker https://linux.die.net/man/1/ld

-l namespec
--library=namespec
Add the archive or object file specified by namespec to the list of files to link. This option may be used   
any number of times. If namespec is of the form :filename, ld will search the library path for a file called   
filename, otherwise it will search the library  path for a file called libnamespec.a.

Here's how it worked for me:

gfortran -Iinclude test_array.f90 lib/libh5fortran.a
