I'm sure that PERL5LIB is what you want, but the mention of "runtime"
mods reminded me of some working code that I use to modify @INC
and load a module before starting up the wrapped perl.
#include <stdio.h>
#include <unistd.h>
int main(int argc, char **argv)
{
int i;
char *myargv[argc+3];
myargv[0] = "pktperl";
myargv[1] = "-I/home/hobbes/tools/perl5";
myargv[2] = "-I/home/hobbes/tools/scripts";
myargv[3] = "-MPktperl";
for (i=1; i<argc; i++) {
myargv[i+3] = argv[i];
}
myargv[argc+3] = 0;
execvp("perl", myargv);
perror("execvp");
return 1;
}
