According to http://gdcproject.org/wiki/UserDocumentation gdc accepts a "-fod=<directory>" flag to "Specify the object output directory. Note: this is actually a driver option; the backend ignores it."
That doesn't work for me: ---------- LANG=C /opt/gdc/bin/gdc -fod=test gdc: error: unrecognized command line option '-fod=test' gdc: fatal error: no input files compilation terminated. ---------- Is this flag still supposed to work or is there a replacement?
