[users@httpd] floatdisf: referenced symbol not found

Hi - I am building Apache2 on Solaris 8 using GCC 3.3.  Everything 
builds OK but one or two of the modules errors on test and startup:

bash-2.03$ /apache2/bin/httpd -X
Syntax error on line 247 of /apache2/conf/httpd.conf:
Cannot load /apache2/modules/mod_status.so into server: ld.so.1: 
/apache2/bin/httpd: fatal: relocation error: file 
/apache2/modules/mod_status.so: symbol __floatdisf: referenced symbol 
not found

LDD doesn't show an error:

bash-2.03$ ldd /apache2/modules/mod_status.so
         libc.so.1 =>     /usr/lib/libc.so.1
         libdl.so.1 =>    /usr/lib/libdl.so.1
         /usr/platform/SUNW,Ultra-250/lib/libc_psr.so.1

nm can see the symbol in libgcc_s.so

bash-2.03$ nm -p /opt/GUgcc33/lib/libgcc_s.so | grep floatdisf
0000007124 T __floatdisf

Commenting out mod_status allows the server to start OK.

Not sure why that's failing; sounds like a build problem.

Does it help if you
LoadFile   /opt/GUgcc33/lib/libgcc_s.so
before loading the offending modules.

You shouldn't have to, but it could be worth a try

LoadFile does indeed remedy this - many thanks.

Is there any way to force those functions from libgcc_s.so to be loaded 
into HTTPD?

Thanks

This usually happens when you build httpd with SO support but
don't build mod_status or mod_cache* at the same time (there
are other modules as well which kick this). The issue is that
when you build httpd, you don't hit any code which requires
those func's (due to the double and quad var usage) so that
httpd doesn't require them from libgcc. If you then use
apxs to build mod_status, etc, *those* modules require
that function, which isn't automatically loaded by
httpd.

You can use LoadFile to force httpd to load it in.
