I'm attempting to install apache 2.2.11 on osx 10.5.6.

I've cd'd to ~/Desktop/httpd-2.2.11 and edited config.layout:

# Leopard Layout

<Layout Leopard>
  prefix: /usr
  exec_prefix: ${prefix}
  bindir: ${exec_prefix}/bin
  sbindir: ${exec_prefix}/sbin
  libdir: ${exec_prefix}/lib
  libexecdir: ${exec_prefix}/libexec+
  mandir: ${prefix}/share/man
  sysconfdir: /etc+
  datadir: /Library/Webserver
  installbuilddir: ${prefix}/share/httpd/build
  errordir: ${prefix}/share/httpd/error
  iconsdir: ${prefix}/share/httpd/icons
  htdocsdir: ${datadir}/Documents
  manualdir: ${datadir}/share/httpd/manual
  cgidir: ${datadir}/CGI-Executables
  includedir: ${prefix}/include+
  localstatedir: /var
  runtimedir: ${localstatedir}/run
  logfiledir: ${localstatedir}/log+
  proxycachedir: ${runtimedir}/proxy
</Layout>

I'm getting the error mentioned in the title when i try to:

./configure --enable-layout=Leopard \
--enable-mods-shared=all \
--with-ssl=/usr \
--with-mpm=prefork \
--disable-static \
--disable-unique-id \
--disable-ipv6 \
--enable-ssl \
--enable-dav \
--enable-cache \
--enable-proxy \
--enable-shared \
--enable-logio \
--enable-deflate \
--with-included-apr \
--enable-cgi \
--enable-cgid \
--enable-suexec

OK -- got apache installed ok with this configure command:

./configure --enable-layout=Leopard \
--with-ssl=/usr \
--with-mpm=prefork \
--disable-static \
--disable-unique-id \
--disable-ipv6 \
--enable-rewrite=shared \
--enable-speling=shared \
--enable-ssl=shared \
--enable-dav=shared \
--enable-cache=shared \
--enable-proxy=shared \
--enable-shared=shared \
--enable-logio=shared \
--enable-deflate=shared \
--with-included-apr \
--enable-cgi=shared \
--enable-cgid=shared \
--enable-suexec=shared

I had to comment out several lines in httpd.conf that tried to load built-in modules, but that was easy beacause when you try to start apache, it will fail and tell you which line to comment.

I will check your findings on the "shared-all" error.

On the modules in the httpd.conf problem, you have an older httpd.conf and the module list has changed since the last time you installed Apache. Therefore old modules who are not compatible with this new version still get loaded and cause errors.

Maybe I need to put something in the documentation about this.
