Can´t compile Fortran code properly about ppp-tools HOT 7 CLOSED

my version of gpsppp (might be old by now) and gfortran (on ubuntu 18.04lts):

Dist34613b/source$ gfortran --version

GNU Fortran (Ubuntu 7.4.0-1ubuntu1~18.04.1) 7.4.0

compile:

Dist34613b/source$ gfortran -o gpsppp2 *.f

(no output at all)

run:

Dist34613b/source$ ./gpsppp2

GPS Precise Point Positioning (CSRS-PPP ver. 1.05/34613/2013-12-12)

+Enter MEASUREMENT input file name :

if there are errors from the ppp-tools python scripts then please include the error message here.

for the gfortran --version I get:
gfortran --version

I suspect that you are missing some files, which should contain the functions that gpspace.f wants. Did you get a working/complete source package from nrcan?

I don't seem to have a gpspace.f file att all in my version

I do have the following files, which probably have some of the functions you are missing gmf.f and gpt2.f and rdmet.f - do you have these?

from ppp-tools.

Yeap, you are right. The source files are now located in external-source folder in github. And gspace.f call all the function, I copied all the files in the main folder and I was successful at compiling it. The exit is different, but now it is running at least. I will try with the python script now.

Now output is:

./gpsppp

thank you for your prompt reply. I will go on with my project.

Just to let you close the issue, I realized I have not the proper fortran code.

So now my question is, where can I get it? Thank
