[Bug 568435] Re: symbol lookup error: /usr/sbin/apache2: undefined symbol: apr_atomic_xchgptr

[rael]

I think the problem is that the apache are still using the old
libraries, i fix it removing manually the old libapr* that apache2 was
using (the path who shows ldd) and then reinstall the new libraries.

Hi!

I fix it removing manually the old libraries that I have on
/usr/local/lib and apache2 remains using that ones:

[CODE]root at posido:/home/rgarcia# cp -up /usr/local/lib/libapr* libapr/
root at posido:/home/rgarcia# rm -i /usr/local/lib/libapr*
rm: remove regular file `/usr/local/lib/libapr-1.a'? y
rm: remove regular file `/usr/local/lib/libapr-1.la'? y
rm: remove symbolic link `/usr/local/lib/libapr-1.so'? y
rm: remove symbolic link `/usr/local/lib/libapr-1.so.0'? y
rm: remove regular file `/usr/local/lib/libapr-1.so.0.2.12'? y
rm: remove regular file `/usr/local/lib/libaprutil-1.a'? y
rm: remove regular file `/usr/local/lib/libaprutil-1.la'? y
rm: remove symbolic link `/usr/local/lib/libaprutil-1.so'? y
rm: remove symbolic link `/usr/local/lib/libaprutil-1.so.0'? y
rm: remove regular file `/usr/local/lib/libaprutil-1.so.0.2.12'? y[/CODE]

and then reinstall the last version using the aptitude:

[code]root at posido:/home/rgarcia# aptitude install libaprutil1
libaprutil1-dev libapr1 libapr1-dev[/code]

and [B]It works![/B] :D

[code]root at posido:/home/rgarcia# /etc/init.d/apache2 start
 * Starting web server apache2 <[/code]


If it doesn't work, check that you are using the correct apr libraries with 

[CODE]root at posido:/home/rgarcia# ldd /usr/sbin/apache2
	linux-vdso.so.1 =>  (0x00007fffe4123000)
	libpcre.so.3 => /lib/libpcre.so.3 (0x00007f3a303b2000)
	libaprutil-1.so.0 => [B]/usr/lib/libaprutil-1.so.0 [/B](0x00007f3a3018f000)
	libapr-1.so.0 => [B]/usr/lib/libapr-1.so.0 [/B](0x00007f3a2ff59000)
	libpthread.so.0 => /lib/libpthread.so.0 (0x00007f3a2fd3c000)
	libc.so.6 => /lib/libc.so.6 (0x00007f3a2f9b9000)
	libuuid.so.1 => /lib/libuuid.so.1 (0x00007f3a2f7b3000)
	librt.so.1 => /lib/librt.so.1 (0x00007f3a2f5ab000)
	libcrypt.so.1 => /lib/libcrypt.so.1 (0x00007f3a2f372000)
	libdl.so.2 => /lib/libdl.so.2 (0x00007f3a2f16d000)
	libexpat.so.1 => /lib/libexpat.so.1 (0x00007f3a2ef44000)
	/lib64/ld-linux-x86-64.so.2 (0x00007f3a3087d000)[/CODE]


I hope it helps.
