Hello, A quick question - what can be wrong: after installing the newest GPC I still get the same error:

/usr/lib/crt1.o: In function `_start': /usr/lib/crt1.o(.text+0x18): undefined reference to `main' collect2: ld returned 1 exit status

while compiling simple:

unit blah; interface implementation end.

To compile a separate unit (i.e. no main program), you have to use the `-c' option, e.g.

gpc -c blah.pas

Is there something wrong with the installation ? (previously I had gcc 2.95.3 installed in /usr/lib, I compiled and installed GPC (by make install) into /usr/local/). Thanks for any hints.

Best Regards, Adam Naumowicz

Previously I had no problems with this patch - maybe now it is not fully compatible with native solaris patch anymore ??

This sounds plausible. I've no experience with Solaris, so this is just a wild guess: line 95 of the patch does not indeed start with '+ ', ' ', or '! ' -- it is empty. Probably Solaris patch doesn't like empty lines in unidiffs, so you may try this as a workaround:

cd gpc-20020410/p/diffs mv gcc-2.95.diff orig.gcc-2.95.diff sed -e 's/^$/ /' orig.gcc-2.95.diff > gcc-2.95.diff

Apparently, I had removed these spaces by accident. I'll put them back, of course. I've made sure that this was the only places where it happened. (And I'm a little surprised that other implementations of patch don't seem to mind.) Thanks for the report, Adam.
