GPC BUG: Problems with automake and autobuild - Gpc

8 Sep 1999


      Hello,
I found the following bug in the Beta version of GPC.
Best regards,
Peter Dietrich
--------------------
GPC-Version (gpc -v):
Reading specs from C:\usr\local\lib\gcc-lib\i386-mingw32\2.8.1\specs
gpc version 19990118, based on gcc-2.8.1
System-Version:
Windows NT 4.0 on i386
Problem description:
If a unit A is included in a USE clause which includes unit B, and B in turn
includes
unit A the compiler gets an error when it tries to compile A again. This is true
 with
option --autobuild and option --automake. The error does not occur if all units
are in
the same directory.
Why does the compiler try to recompile A?
Looking at the gpi file I found that only the filename is stored, not the full
or
relative path name.
In the following test case replace A by "windows.pas" and B by "sysutils.pas":
