Re: [gtk-list] objgtk vs. threads on RH 4.2

[johannes nada kth se (Johannes Keukelaar)]

//
//On my RH 4.2 system (linuxthreads-0.5-1,libc-5.3.12-18), I get 
//no gnome programs in obj-c to work:
//
//E.g. 
//
//$./gulp
//
// ** ERROR **: Could not create per-user Gnome directory
//</home4/robert/.gnome> - aborting
//
//IOT trap/Abort (core dumped)
//
//
//Removing libpthread from the Makefile fixes this:
//
//OBJC_LIBS = -lobjc #-lpthread
//
//This seems to be related to different errno definitions in the different 
//libs. E.g. gulp breaks when doing a (mkdir(/home4/robert/.gnome,0700) &&
//errno != EXISTS)

The problem is not so much that the errno definitions differ, but that errno in 
libc5 under Linux is not thread safe. I.e. if one thread sets errno to 
something, it will be set for all threads. Basically, if you want to do 
threads, go for libc6. (As far as I know, though, switching libc is _not_ 
trivial. Go for a nice new distribution such as RH5. (Although that has other 
problems.))

Johannes.
