Fwd: out-of-tree module config.h documentation/use

GNU Radio

Hi

I am writing an out-of-tree module and have used the gr_modtool to
generate
the module and block skeletons. All the block source files include a
config.h file, but I have not been able to find documentation of its use
or
location anywhere.

Does anyone know what it is used for and how?

Thank you,

David Marmoy

It’s probably an artefact from the autotools era.
Note that it’s:

21 #ifdef HAVE_CONFIG_H
22 #include “config.h”
23 #endif

So the include is never called.

These config.h files are usually generated by the build process, and
provide information about the system you’re building on. CMake handles
that a bit differently, so we don’t really use these anymore.

We could of course generate such a file with CMake, but we currently
don’t.

Cheers,
M
