Hi, When I try to compile the February 2000 release of hugs with latest releases of linux glibc (found in redhat 7.0 and the development distribution of debian), I get the following errors: gcc -c -g -O2 builtin.c In file included from builtin.c:1431: iomonad.c: In function `primHGetPosn': iomonad.c:715: aggregate value used where an integer was expected iomonad.c: In function `primHSetPosn': iomonad.c:730: invalid initializer iomonad.c:736: incompatible types in assignment make: *** [builtin.o] Error 1 This is caused by changes to the fpos_t type, which is no longer directly castable to an int. I'm not sure what the appropriate fix is, since there don't seem to be accessor functions for the type - making the source look inside the structure that fpos_t has become would then break with older glibcs. I've just removed the references to fgetpos and fsetpos from src/unix/configure.in to make it compile for now. Regards, Ganesh Sittampalam
