configured with

./configure \
 --with-apxs=/usr/local/apache/bin/apxs \
 --with-config-file-path=/usr/local/apache/conf \
 --enable-versioning \
 --with-mysql \
 --enable-ftp \
 --with-gd=/usr/local/gd1.3 \
 --enable-bcmath \
 --disable-debug \
 --enable-memory-limit=yes \

reported it found iconv ok

i installed libiconv from freshmeat source

it produces on apache start

Cannot load /usr/local/apache/libexec/ into server: /usr/local/apache/libexec/ undefined symbol: libiconv_open
/usr/local/apache/bin/apachectl sslstart: httpd could not be started

actually as well to configure

(also tried just --with-iconv)

Does this happen with latest CVS snapshot: ?

OK I had a think and changed the configure statement to:

'./configure' '--with-apxs=/usr/local/apache/bin/apxs' '--with-config-file-path=/usr/local/apache/conf' '--enable-versioning' '--with-mysql' '--enable-ftp' '--with-gd=/usr/local/gd1.3' '--enable-bcmath' '--disable-debug' '--enable-memory-limit=yes' '--enable-track-vars' '--with-iconv=/usr/local/lib'

this builds and loads OK, iconv is enabled in the phpinfo();

However if I create a test page with just the iconv example, it takes some time, but sometimes eventually says the function isn't defined, other times it produces a seg fault.

This at least means I can get a backtrace so here it goes:

This GDB was configured as "i386-redhat-linux"...
