Hi EveryOne, Thanks everybody for your response of my previous letter. I still have a problem compiling Ipass module for radiator. I think I have fixed the cpp problem but still cannot compile successfully. I am running solaris 2.6x86. The error I got during compilation is below. gcc -c -I/usr/ipass/include -I/usr/local/include -DVERSION=\"1.3\" -DXS_VE RSION=\"1.3\" -fPIC -I/usr/local/lib/perl5/5.00502/i86pc-solaris/CORE Ipass.c unknown flag -lang-c unknown flag -Asystem(unix) unknown flag -Asystem(svr4) unknown flag -Acpu(i386) unknown flag -Amachine(i386) "/usr/ipass/include/ipassgen.h", line 42: Can't find include file sys/cdefs.h *** Error code 1 make: Fatal error: Command failed for target `Ipass.o' My thinking is that the compiler does not know these flags so how do I get these flag in the compiler or can I compile Ipass module without these flags. === To unsubscribe, email '[EMAIL PROTECTED]' with 'unsubscribe radiator' in the body of the message.
