After much pain and heartache, I have found a solution for all of you
Manx users who need exec() or fexec() under 1.2 but don't have any
updates. Compile, link, and run the following program in a directory
which also contains a copy of the Version 3.20a c.lib and c32.lib.
It will patch the libraries so the exec() and fexec() functions work
under AmigaDOS 1.2 but NOT under 1.1. By the way, a bug: fexecl() is
equivalent to execvp(), and does NOT return to the calling program.
Use fexecv() for that.
--------------cut here: compilers don't speak English------------
/*
* Patch for Aztec C Version 3.20a c.lib and c32.lib to enable
* exec() and fexec() to work under AmigaDOS 1.2.
*/
#include "fcntl.h"
main()
{
int fd;
fd = open("c.lib", O_RDWR);
if (fd > 0) {
lseek(fd, 0x303eL, 0);
write(fd, "\xa8", 1);
lseek(fd, 0x348aL, 0);
write(fd, "\xa8", 1);
close(fd);
}
fd = open("c32.lib", O_RDWR);
if (fd > 0) {
lseek(fd, 0x3176L, 0);
write(fd, "\xa8", 1);
lseek(fd, 0x35beL, 0);
write(fd, "\xa8", 1);
close(fd);
}
}
------------------cut here too---------------------------------
That's it! Use it in good health.
