Update: I've ported the bootstrap script to DCL (yuck) and it has most of the functionality of the bash version of the script. I decided to take a dependency on the A9 porting library a.k.a. "The Jackets" (http://h71000.www7.hp.com/openvms/products/ips/porting.html) to help with some of the small issues I was having with compatibility of unix header files. It also includes a port of gmake (3.76.1).
Compiling the bootstrap I run into only one issue: In ProcessUNIX.c, there is a sigaction struct, and the version on VMS does not have the sa_sigaction member of the sigaction struct, and correspondingly the SA_SIGINFO constant is not defined. The sigaction struct looks like this: void (*sa_handler)(int); sigset_t sa_mask; int sa_flags; As a fix would I get correct results if I were to instead of sa_sigaction, assign to sa_handler (the Unix manpage seems to claim that on some implementations sa_sigaction and sa_handler are a union - so they end up being called for the same reasons. My logic maybe flawed here. -Alan On 9/20/07, Bill Hoffman <[EMAIL PROTECTED]> wrote: > > Alan Antonuk wrote: > > Hi; > > > > I'm trying to get cmake to run on the OpenVMS operating system with a > > goal of eventually getting ITK to run on VMS.
