TROUBLESHOOTING
===============
Please evaluate these points before reporting an issue on the mailing list.
- Make sure to have carefully read this document.
- Make sure to use a supported GNU Make version as indicated in
this document. Older versions are buggy and won't work.
- Make sure to do a 'clean' before doing a build after refreshing
the sources.
- Make sure to do a fresh checkout from the sf.net source repository
to a new local directory and start over.
Use this command for the checkout:
svn export https://harbour-project.svn.sourceforge.net/svnroot/harbour-project/trunk/harbour
- Keep you PATH clean from old, mixed compiler tools or other Harbour
versions when building Harbour.
- Remove all old, unnecessary envvar settings from your environment.
Use only those documented in this file.
- Pay attention to CLIPPER and HARBOUR envvars, for a Harbour build
it's best to clear them.
- Try to do no or only small modifications at once to command examples
included in this file. If it doesn't work, fall back to documented
examples as is.
