Just guessing:
- there is an issue with the path given for mapping files (absolute/
relative)
- the shared drive has trouble with temporary files or the like
(happens with some network drives)
Anyway, the use of mapping file is there for speeding up the build, so
it should make sense only on a fast drive (local hard disk or RAM
disk), in most of the cases.
You have probably the -C[=3Dxxx] option in the gnatmake command, just
remove it or the "=3Dxxx" and you'll be happy!

  -C       Cache source mappings: invoke compiler with temp mapping
file
  -C=3Dmapp  Cache source mappings: invoke compiler with mapping file
mapp
