I decided to go with the cvs builds of apache and mod_perl. I have to confess that the installation instructions seem strange (both for CVS and non-CVS). You have to build and install Apache in order to get the include files to build mod_perl.

I assume after all of this you do make install on both Apache and mod_perl although the doc doesn't say so. the docs are broken then. all you have to do is: - install perl - install apache - build modperl with: perl Makefile.PL MP_AP_PREFIX=/usr/local/apache2 make test make install I suppose I could have done --enable-threads in Apache with --with-mpm=prefork and it might have worked. Is that considered kosher? maybe. but if you are using prefork, no need to build perl with -Dusethreads

I should also mention -- my perl is patched with the patch

I had already thought of that. Strace shows that the

to make sure I deleted all others and did

but strace tells me that it is still directly loading the correct
one, probably because of the
-Wl,-R/usr/lib/perl5/5.6.1/i386-freebsd-thread-multi/CORE
used in linking mod_perl.so.
ok.
That being said I tried the LoadFile directive as you suggested.
This indeed lets the system start, but now it can serve no
pages ( not even static ones ). This is true even when all
mod_perl configuration directive are removed from the conf
file (except the LoadFile and the LoadModule).
However, when I do httpd -X, it
works - I can even serve mod_perl content. But regular httpd
just hangs. The strace output of an httpd process shows this:
accept(5, {sin_family=AF_INET6, sin6_port=htons(1303), inet_pton(AF_INET6,
:::65.204.1.133, sin6_addr), sin6_flowinfo=0}, [28]) = 20
could this be a version of freebsd with broken threads support? i've
heard many cases of that. chances are if you rebuild perl without
-Dusethreads and apache with the prefork mpm, this problem won't be there.

so the problem that I see on linux is unrelated?
this tested with prefork Apache cvs and perl built as:
./Configure -des -Dprefix=/home/stas/perl/5.6.1-ithread \
-Dusethreads -Doptimize='-g' -Duseshrplib -Dusedevel

RE: Perl_Tstack_sp_ptr
OK, until I can decide whether to take a chance on FreeBSD-current or to convince my employers who were so enamored of FreeBSD that we should rebuild the server with Linux, I'm going prefork. It still doesn't work precisely as it should though. I decided to go with the cvs builds of apache and mod_perl. I have to confess that the installation instructions seem strange (both for CVS and non-CVS). You have to build and install Apache in order to get the include files to build mod_perl.

I assume after all of this you do make install on both Apache and mod_perl although the doc doesn't say so. Even after all of that I *still* get the Perl_Tstack_sp_ptr error! Putting in the explicit LoadFile for libperl.so gets rid of that problem, only to create another: Cannot load /usr/lib/perl5/5.6.1/i386-freebsd-thread-multi/CORE/libperl.so into server: /usr/lib/perl5/5.6.1/i386-freebsd-thread-multi/CORE/libperl.so: Undefined symbol pthread_getspecific Presumably this is because the Perl I used had thread support. My workaround is to edit apachectl to preload libc_r.so: start|stop|restart|graceful) LD_PRELOAD=libc_r.so $HTTPD -k $ARGV ERROR=$? ;; startssl|sslstart|start-SSL) LD_PRELOAD=libc_r.so $HTTPD -k start -DSSL ERROR=$? and finally everything appears to be working. I suppose I could have done --enable-threads in Apache with --with-mpm=prefork and it might have worked. Is that considered kosher?

That can't be good, can it? Here is why I think so: INSTALLATION The current FreeBSD POSIX thread implementation is built in the library libc_r which contains both thread-safe libc functions and the thread functions. This library replaces libc for threaded applications. By default, libc_r is built as part of a 'make world'. To disable the build of libc_r you must supply the '-DNOLIBC_R' option to make(1). A FreeBSD specific option has been added to gcc to make linking threaded processes simple. gcc -pthread links a threaded process against libc_r instead of libc. -P [/usr/local/apache2/htdocs/perl]# LD_TRACE_LOADED_OBJECTS=1 \ /usr/local/apache2/bin/httpd libaprutil.so.0 = /usr/local/apache2/lib/libaprutil.so.0 (0x280a9000) libapr.so.0 = /usr/local/apache2/lib/libapr.so.0 (0x280b9000) libm.so.2 = /usr/lib/libm.so.2 (0x280d4000) libcrypt.so.2 = /usr/lib/libcrypt.so.2 (0x280f) libssl.so.3 = /usr/lib/libssl.so.3 (0x28109000) libcrypto.so.3 = /usr/lib/libcrypto.so.3 (0x28136000) libexpat.so.1 = /usr/local/apache2/lib/libexpat.so.1 (0x281ea000) libc_r.so.4 = /usr/lib/libc_r.so.4 (0x28206000) libc.so.4 = /usr/lib/libc.so.4 (0x282bb000) [/usr/local/apache2/htdocs/perl]# readelf -dD /usr/local/apache2/lib/libapr.so.0 Dynamic segment at offset 0x1941c contains 17 entries: TagType Name/Value 0x0001 (NEEDED) Shared library: [libc.so.4] 0x000e (SONAME) Library soname: [libapr.so.0] 0x000c (INIT) 0x5f08 0x000d (FINI) 0x18164 0x0004 (HASH) 0x94 0x0005 (STRTAB) 0x3494 0x0006 (SYMTAB) 0x1184 0x000a (STRSZ) 8540 (bytes) 0x000b (SYMENT) 16 (bytes) 0x0003 (PLTGOT) 0x19fc8 0x0002 (PLTRELSZ) 2072 (bytes) 0x0014 (PLTREL) REL 0x0017 (JMPREL) 0x56f0 0x0011 (REL)0x55f0 0x0012 (RELSZ) 256 (bytes) 0x0013 (RELENT) 8 (bytes) 0x (NULL) 0x0 -Original Message- From: Doug MacEachern [mailto:[EMAIL PROTECTED
