RE: FW: Error running make for subversion

Thanks for all the answers. They are helping me learn more.
I looked in the config.log for linker to shared libraries:
configure:11966: checking whether the gcc linker (/usr/bin/ld) supports shared libraries
configure:12589: gcc -o conftest -g -O2 -O2 -pg -pthread -U__STR__ -D_THREAD_SAFE -D_LARGEFILE64_SOURCE -L/opt/freeware/lib conftest.c
>&5

.

configure:18335: result: immediate
configure:18447: building shared libraries only
configure:18495: checking whether libtool needs -no-undefined
configure:18504: result: no
.
So, linker (usr/bin/ld) is not GNU ld
g++ linker (usr/bin/ld)supports shared libraries (warnings?)
gcc linker (usr/bin/ld)supports shared libraries
libtool supports share libraries
Yes to building shared libraries
No to building static libraries.

Is there anything here that is not quite right?
Thanks for your help.

That didn't work either. It does not appear to pick up the flag.
I will get back at it tomorrow morning.
Thank you for your help

Here is an old email that suggests which linker flags are needed to create .so, rather than .a, shared libraries:

https://gcc.gnu.org/ml/gcc-help/2002-05/msg00065.html

Perhaps edit your Makefile and add -Wl,-G to the end of the LINK_APACHE_MOD line.
