Can anyone help with this? We have an application that runs fine on our linux workstations, but will not compile to run on a new target. This application is using the WNOWAIT option for the waitid() function. When the source file is compiled for the target using powerpc-uclibc-gcc, it fails because WNOWAIT is not defined. The best that I can tell, waitid() doesn't appear to be supported in uClibc (version 0.9.27). I checked the latest version on the uClibc site, but it doesn't appear to have been considered for inclusion. I looked in glibc (versions 2.4, 2.3.5, and 2.0.6), but could only find emulated/stub/pseudo implementations for waitid(). The Linux man page for waitid() states that it's supported since the 2.6.9 kernel release. At this point I'm not sure where the waitid() source code and WNOWAIT definition is suppose to be (kernel, uClibc, glibc, gcc) or what version of wait.h is actually being used (there appears to be many versions floating around on the machine). Since I'm way off in the weeds on this I was hoping somebody with more Linux experience than me (that would be just about anyone) might be able to shed some light on this problem or point me in a more constructive direction.
Do you have any information as to the status of the waitid() support? It must have been available at one time since it's running on my linux workstation (Linux version 2.6.15-1.2054_FC5smp ([EMAIL PROTECTED]) (gcc version 4.1.0 20060304 (Red Hat 4.1.0-3)) #1 SMP Tue Mar 14 16:05:46 EST2006). Was there a reason why it wasn't added to uClibc (other than the size issue)? Is there a recommended way to deal with applications that are using waitid() with the WNOWAIT option?
