Hi, I am running Mac OS X 10.4.8 on a MacBook Intel 2Ghz Core Duo, using gpc installed from gpc345u2-intel.dmg (downloaded from http:// www.microbizz.nl/gpc.html). When compiling I get errors involving "indirect jmp without `*'" as in $ gpc helloworld.p /var/tmp//ccz2cAa1.s:110:indirect jmp without `*' /var/tmp//ccz2cAa1.s:127:indirect jmp without `*' /var/tmp//ccz2cAa1.s:144:indirect jmp without `*' /var/tmp//ccz2cAa1.s:161:indirect jmp without `*' /var/tmp//ccz2cAa1.s:178:indirect jmp without `*' /var/tmp//ccz2cAa1.s:195:indirect jmp without `*' /var/tmp//ccz2cAa1.s:212:indirect jmp without `*' where helloworld.p is program helloworld(input, output); begin writeln('Hello world') end. Do you know what the problem is? Thanks, Nestor Aguilera
