Hi all,
I was just trying to compile one of my programs that includes

Hmm, on linux the maximum PID can be changed dynamically at run time.
Wouldn't it be better to change this to read /proc/sys/kernel/pid_max?
I've just upgraded linux-headers to 2.6.19 - is this the problem?
It seems so. From kernel-2.eclass:
# 2.6.18 introduces headers_install which means we dont need any
# of this crap anymore :D
if kernel_is ge 2 6 18 ; then
env_setup_xmakeopts
emake headers_install
INSTALL_HDR_PATH=${D}/${ddir}/.. ${xmakeopts} || die
In other words, for versions previous to 2.6.18, (almost) all headers
in the tarball were installed. For 2.6.18 and later, the makefile in
the tarball defines what gets installed.
If you truly need this header, make a private copy for your source
directory, or just define PID_MAX_DEFAULT yourself. But as I
mentioned above, it can be changed at run-time, so relying on this to
be constant could be dangerous.

[gentoo-user] [OT] where is PID_MAX_DEFAULT ?
Hi all, I was just trying to compile one of my programs that includes linux/threads.h for the #define PID_MAX_DEFAULT, however, threads.h isn't there anymore! I've just upgraded linux-headers to 2.6.19 - is this the problem? I can't find a replacement for PID_MAX_DEFAULT anywhere in the header files - has the name changed? google was also unhelpful AFAICT. I'd appreciate help! thanks, -- Iain Buchanan iaindb at netspace dot net dot au Nothing cures insomnia like the realization that it's time to get up. -- gentoo-user@gentoo.org mailing list

I could find thread.h file there! Maybe your tar ball of kernel has been damaged! you could download it again and have a try !

Since it s a system package you should already have it. There is also another version of threads.h which comes with the kernel source: /usr/src/linux/include/linux/threads.h, but AFAIK it is recommended to use the first one. -- Best regards, Daniel -- gentoo-user@gentoo.org mailing list
