Mark,
You hit the nail on the head. Although not critical at this point it will
be critical in the future to specify command line arguments in a file. The
problem with the command line limit is actualy universal IRIX, HP, AIX,
Linux etc. Both IRIX and Linux have a 4 MB limit for the command line. The
shell often has a lower limit, which can be changed, but nver the less
using the command line one has to got through exec and 4 MB is it. Thus if
there is a long link line with thousands of object files one is screwed if
there is no command file option.
IS there a secret handshake between gcc and ld to get a large number of
object files to be linked to ld without going through exce and without
trying to mangle up a linker script?
Thanks,
Robert
