In cases of only a .pdf or other electronic media, I've had good luck downloading to a flash drive, then taking it to an OfficeMax or OfficeDepot store, where they printed and bound it. But that was back in the day when a sheet of copied paper cost less than a nickel.

I guess technically not a manual, but your documentation under "Help" in the idea in the Windows IDE. The Help in the Linux version (which I mostly use) is not as complete, probably hard to port it - I know next to nothing about GUI's. The windows help contents are very thorough. It is very difficult for my brain to absorb info digitally, so I almost always purchase paper manuals. I'd purchase yours if you had one.

what's the title of that manual?

Apologies Jeff. It's all there in your excellent documentation clear as day. Bad habit but in Windows I tend to take things for granted. I'm now reading your manual (at least the section on using the SF IDE) in its entirety as I should have months ago.

Thank you Jeff. That worked for all the various libraries/modules I had been having trouble with. I may be confused. I had expected that having the "default include/module/add--on/library directories) added in the "File Locations" tab was all I needed to do having the package manager, since stdlib has always worked without having to compile the source.

Bryan,

What are your Compiler Flags (in Project Options) set to? You need to make sure

-lm_io

is included in the Linker flags box. The reference to __m_io_MOD_dirname does appear to be in the library.

Hi,

I have m_io.mod which I downloaded using sfpm.

use stdlib_kinds
use m_io, only: basename, dirname

IDIR=-IC:/Users/truep/AppData/Local/sfpm/32/include -IC:/FORTRAN/PROJECTS/TPPOST/modules

yet I get error:

C:\FORTRAN\PROJECTS\TPPOST/./src/tppost.f90:221: undefined reference to `__m_io_MOD_dirname'

Any idea why it's not linking? I'm also using stdlib and no issues there.

I've had to add the m_io.f90 source to my project and compile it to my ./modules folder to compile/build.

Trying to use libraries as this project is getting huge...

Thanks,
Bryan
