Hi,
I had some trouble to get GWorkspace to run on OpenBSD 4.1. I took the
OpenBSD ports from http://mail.rochester.edu/~asveikau/gnustep-openbsd/,
updated them to use gnustep-make-2.0.1, gnustep-base-1.15.0,
gnustep-gui-0.12.0, gnustep-back-0.12, and GWorkspace-0.8.6.
After installing, trying to start it, GWorkspace aborted with the following
message:
Critical Error in GWorkspace
NSInvalidArgumentException: NSTask - launch path (mount) not valid
It took me a while to find out what this message wants me to know. After
running GWorkspace it in the debugger, I saw it stopping here:
(gdb) bt
...
#10 0x0a34f3c5 in -[NSWorkspace(mounting) mountedVolumes] (self=0x87b4e928,
_cmd=0x2a347848) at FSNodeRep.m:756
...
This NSWorkspace's -mountedVolumes method, implemented by gworkspace in a
category, is necessarily a compromise, an hack; the criteria it uses are:
#ifdef __APPLE__
it uses getmntinfo() - tested on darwin.
#else
#if defined(HAVE_GETMNTENT) && defined(MNT_DIR)
it uses getmntent() - this is the default on linux.
#else
it uses [[NSProcessInfo processInfo] operatingSystem] and takes in
consideration two cases:
NSGNULinuxOperatingSystem:
it parses /etc/mtab - this has been tested by me on Linux
commenting the getmntent() part.
NSBSDOperatingSystem:
it uses a NSTask, that is, the output of "mount -p" - this has been
suggested by a FreeBSD user and should return a NSString equivalent to the contents of
/etc/mtab on Linux. Untested by me.
For all the other cases an empty NSArray is returned.
I've not OpenBSD; the only solution I can see is if you write a patch for this method or
(simplier) tell me the equivalent on OpenBSD for "mount -p".
The problem is easily explained: on OpenBSD mount is in /sbin, not in /bin.
/sbin is not in $PATH environment variable of the user, therefore GWorkspace
does not find the mount command automagically. The fix is to add /sbin to the
PATH environment variable. With this done, I see another error message on the
console regarding mount. Mount is called with parameter -p (on Linux to
specify a file descriptor to read passwords from). This parameter does not
exist on OpenBSD, therefore at least one call to mount fails, but does not
seem to be fatal.
