I did the follow

tar zxvf php-4.0.4pl1.tar.gz
cd php-4.0.4pl1
./configure --with-mysql --with-apxs
make

I receive the follow error messages after make:

--------

It look like some necessary source files are missing. Is this caused by RaQ OS Update 4.0?

I tried "locate" to locate the files:

[admin@www /]$ locate limits.h
/usr/include/limits.h
/usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.66/include/limits.h
/usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.66/include/syslimits.h

[admin@www /]$ locate errno.h

/usr/include/errno.h

/usr/include/pgsql/ecpgerrno.h

/usr/i386-glibc20-linux/include/linux/errno.h
/usr/i386-glibc20-linux/include/sys/errno.h

Has anyone a idea why make didn't find the files and PHP won't compile?

I think i found the problem.

Kernel is kernel-2.2.14C10-1 but Kernel headers 2.2.14C10-1 is not installed, only headers 2.2.14C5-1.

Is kernel-headers-2.2.14C10-1.i386.rpm (available at ftp://ftp.cobaltnet.com/pub/experimental/) the right rpm for the RaQ3?

I suggest you install whole new http from scratch. apache1.3.17,php4.0.4 etc...it feel far better.(test installation on your home's redhat linux machine first, if it's done , your raq's installation will be fine)
