According to Paul Doerwald:
Well, the other thing Peter suggested to me was this:
in version.c, make this change:
char *version_string = "2.8.0"
This should not be necessary any more, but ...
According to Clyde Meli:
I changed it to indicate 2.8.1 which is the gcc I'm using. And I got a different error now...
... it seems to be the reason. Strange. I will investigate that.
gpc1: installation problem, cannot exec `gpc': No such file or directory gpc1: gpc exited with status 255
Grmblpfl ... some stupid bug in the automake mechanism. Please copy or link your `xgpc' to `gpc' in a directory in your path to work around.
gpi-hash.c:329: failed assertion `rp == 0'
That's an incompatibility in different versions of the GPI file format. Deleting all `.gpi' files should help.
(If somebody wonders why I was so quiet during the last days: Due to the hot weather in Germany (--> hardware failures) I have been offline for about 30 hours and now I have about 300k of new email.)
