compile error - "proj version 4 required"

[ilikeleptons]

I just pulled the latest version of the sources of goestools. When I try to compile goesproc (I believe) I get an error stating that "proj version 4 [is] required". Let me know what additional information you'll need, I'm a little new to this.

Here is the output from when I make the project, I can't seem to bold face the errors, but they start at around the 89% mark or so.

Thanks for reporting the issue!

The output you included was a bit verbose so I edited it down to the relevant part.

Can you post the output of cmake instead of the output of running make? That will include information on the actual version of libproj you have installed. The fact that you got past that stage implies that CMake was able to find some version of libproj, just not the right one.

Please also include the operating system you're using and any relevant version information.

ah, i forgot to mention that before i was building it from the archlinux user repository. however, when i instead follow the build instructions in README.md, i get far less progress:

cd goestools ~
isaac@thnikdap> mkdir -p build ~/goestools
isaac@thnikdap> cd build ~/goestools
isaac@thnikdap> cmake ../ -DCMAKE_INSTALL_PREFIX=/usr/local ~/goestools/build

Perhaps the submodules are missing? Try:

git submodule init
git submodule update

@ilikeleptons This problem will be resolved by the submodule initialization like @eminence.

I just checked the Arch Linux repository for proj and it has version 5.2.

I hit this problem too with Ubuntu 19.04, which also ships Proj 5.20.
The submodule suggestion didn't work for me (doesn't look like proj is vendored in?), but while digging around I noticed that proj_api.h shipped with 5.20 is compatible with the proj4 API, so I've created a small PR (in #43 ) which allows compilation to proceed when either proj version 4 or 5 are detected.

This allows the build to successfully complete on my machine.
Hope it's helpful!

Thank you for fixing this!
