Fails on musl libc systems because function 'rexec' is missing.

Likely just a package error, but more and more systems are not packaging rexec these days, so it might be worth your attention.

Thanks.

Is there a preprocessor symbol to identify this system, or compiler, or library?

[finnoleary]

Apologies for not responding sooner, my git folder got piled with random clutter.

Unfortunately musl libc does not have a __MUSL__ macro or anything of the kind (which was news to me!).

It seems it should be possible to deduce a MUSL system by the lack of __GLIBC__, but it's probably better to just have a compile check for if rexec is undefined, instead?

sorry for adding to an old issue but im also having this issue on openbsd, is there a solution to this?

It is strange that you get this on OpenBSD, seeing that is special cased to not use rexec(3) specifically on that platform? I just compiled it on OpenBSD 6.6-snapshot, and there I do not have any issues whatsoever.

As a quick hack, you could simply kill the following lines:

itstar/tapeio.c

Lines 226 to 232 in 47c628c

	#if !defined(__APPLE__) && !defined(__OpenBSD__)
	if((tapefd=rexec(&p,htons(512),user,NULL,"/etc/rmt",
	(int *)NULL))<0) {
	perror("?Connection failed");
	exit(1);
	}
	#endif
