Hello, To setup paths we need to known if a program (texi2any) is called in-source/in-build or from the installation directory. Is there a way to detect if a C program is called in-source/in-build or after installation? For Perl we use mainly a trick that in-source scripts have .pl and do not have configure values substituted (ie '@datadir@' is still '@' .'datadir@') while installed scripts have configure values substituted. We also can also use an environment variable to be able to call the scripts with configure values substituted in-build/in-source, which I will implement in C, but I would prefer to also have something like the .pl trick, there is much less risks of mixing up the two programs.
The C program has always the configure values available, as it always need to include config.h and the variables passed with -D are always set too. I tried to search on the www, but did not find anything relevant. Any idea? Any example of how it is done in other projects? -- Pat
