problem compileing php4.0.2

Anon

I have a RedHat 6.1 machine with a kernel 2.2.16 which I installed with rpms from redhat. Upgraded because of the security exploit in 2.2.14.
./configure runs fine

When I compile I get the following error

Making all in Zend
make[1]: Entering directory /usr/local/php-4.0.2/Zend' /bin/sh ../libtool --silent --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I.. -DEAPI=1 -DXML_BYTE_ORDER=12 -g -O2 -c zend-scanner.c In file included from /usr/include/errno.h:36, from ./zend-scanner.l:40: /usr/include/bits/errno.h:25: linux/errno.h: No such file or directory make[1]: *** [zend-scanner.lo] Error 1 make[1]: Leaving directory/usr/local/php-4.0.2/Zend'
make: *** [all-recursive] Error 1

I look in /usr/include/bits/ and errno.h
is there.

Thanks for your help.

Hi,

I think that the kernel sources are missing.
Install the 2.2.16 kernel sources. You might need to do a make config in the kernel source tree. That should solve you problem.

Your right all I had to do was run make config. I'm glad I didn't have to actually compile the kernel because there are too many questions I just am not sure of. I'd like a more complete howto on compiling the kernel but that's way off topic

Thanks

I spoke too soon I'm geting the same error maybe I do have to recompile the kernel? I'm not happy about it.

Hi,

I missed something:

make sure that there is a symlink /usr/include/linux that points to the include directory of the kernel sources.

The complete path to errno.h is
/usr/include/linux/errno.h

I think make config should do it. A recompilation is not neccessary.

I got it!
make config didn't do it
When upgrading the kernel from 2.2.14 to 2.2.16 with rpm the symlinks from /usr/include/asm > /usr/src/linux/include/asm and
/usr/include/linux > /usr/src/linux/include/linux aren't recreated and must be reinstalled by hand. Finaly found this in redhats bugzilla.

thanks for all your help,
