Hi,

When trying to compile svn HEAD on MacOS 10.3.9 I get the
following error:

cd /Users/chris/src/slang/src/objs; gcc -c -g -O3 -I/sw/include -Dunix -DSLANG /Users/chris/src/slang/src/slproc.c
/Users/chris/src/slang/src/slproc.c: In function `setpgrp_cmd':
/Users/chris/src/slang/src/slproc.c:150: error: too few arguments to function `setpgrp'
make[1]: *** [/Users/chris/src/slang/src/objs/slproc.o] Error 1
make: *** [static] Error 2

Configure params:

FINKPREFIX=/sw ./configure --prefix=/usr/local --with-pcre=/sw --with-png=/sw

Am I doing something wrong? Can I provide more info?

TIA

It appears that setpgrp takes an argument on some systems but not on
others. So I will have to add a check for that. Would you mind
sending me your manpage for setpgrp?

Thanks,

Apparently this is an alias for setpgid here:


SETPGID(2) BSD System Calls Manual SETPGID(2)

NAME
setpgid, setpgrp - set process group

SYNOPSIS
#include <unistd.h>

int
setpgid(pid_t pid, pid_t pgrp);

int
setpgrp(pid_t pid, pid_t pgrp);

DESCRIPTION
Setpgid() sets the process group of the specified process pid to the
specified pgrp. If pid is zero, then the call applies to the current
process.

If the invoker is not the super-user, then the affected process must have
the same effective user-id as the invoker or be a descendant of the
invoking process.

RETURN VALUES
Setpgid() returns 0 when the operation was successful. If the request
failed, -1 is returned and the global variable errno indicates the rea-
son.

ERRORS
Setpgid() will fail and the process group will not be altered if:

[EACCES] The value of the pid argument matches the process ID
of a child process of the calling process, and the
child process has successfully executed one of the
exec functions.

[EPERM] The effective user ID of the requested process is dif-
ferent from that of the caller and the process is not
a descendant of the calling process.

[ESRCH] The value of the pid argument does not match the pro-
cess ID of the calling process or of a child process
of the calling process.

SEE ALSO
getpgrp(2)

STANDARDS
The setpgid() function conforms to IEEE Std 1003.1-1988 (``POSIX.1'').

COMPATIBILITY
Setpgrp() is identical to setpgid(), and is retained for calling conven-
tion compatibility with historical versions of BSD.

Thanks for looking into this.

Hopefully the latest svn check-in resolves this issue.

$ slsh --version
slsh version 0.8.1-0; S-Lang version: pre2.1.0-88
