Dear Moderators:

Hi, I am a beginner using GALPROP. I have installed GALPROP version 56 on my research team's cluster and I encountered this problem when trying to run an example routine "galdef_56_example" provided in GALPROP_v56 package.

Some output information are listed below:
...

readFromFitsWcs: This functionality requires the WCS library
terminate called after throwing an instance of 'std::runtime_error'
what(): Recompile with WCS
Aborted (core dumped)

It seems that the error occurs when looking for WCS library in the computer, so I installed WCS library in the path /usr/local/lib from http://www.atnf.csiro.au/people/Mark.Calabretta/WCS/. I rerun but it doesn't work.

During I configured the installation of galtoolslib, I didn't install WCS library as this library is optional said in the README file. How can I configure GALPROP so that it can know where the WCS library is? Should I reinstall galtoolslib and GALPROP after having WCS library installed?

I have attached the example galdef file.

Appreciate for any help.

Thank you for reporting this, the README should be updated and WCS actually required. The solution is to rebuild galtoolslib with WCS and then re-link galprop.
