>Description:
After installing apache2 on freebsd4.8, MPM=prefork (i.e. default),
$ apxs -q EXTRA_CPPFLAGS
-D_REENTRANT -D_THREAD_SAFE
$ ldd /usr/local/sbin/httpd
...
libc.so.4 => /usr/lib/libc.so.4 (0x4824c000)
and strings /usr/local/sbin/httpd | grep pthread
gives nothing.
I don't get it; why _REENTRANT and _THREAD_SAFE if there are no
threads, and httpd is linked with libc, not libc_r? Seems like a bug
to me? The gcc manpage says to use thread_safe only when linking with
ptreads, here we don't...
This breaks mod_jk that I'm porting right now... apache fails to run
with the built mod_jk:
Cannot load /usr/local/libexec/apache2/mod_jk.so into server:
/usr/local/libexec/apache2/mod_jk.so: Undefined symbol
"pthread_mutex_unlock"
Hence, this sometimes breaks module building, if the module trusts
apxs to give correct CFLAGS & CPPFLAGS.
>How-To-Repeat:
build apache2 without any extra options, (on freebsd 4.8)
$ apxs -q EXTRA_CPPFLAGS
-D_REENTRANT -D_THREAD_SAFE
although httpd is linked with lib_c.so
