======Troubleshooting: Problems compiling Evergreen======

=====apr.h error (apr_off_t)=====
====Problem====
Error message returned during make:
<code>In file included from /usr/include/httpd/ap_config.h:25,
                      from /usr/include/httpd/httpd.h:43,
                      from apachetools.h:1,
                      from apachetools.c:1:
/usr/include/apr-1/apr.h:270: error exprected '=', ',',':', 'asm' or
'__attribute__' before 'apr_off_t'</code>
====Solution====
On February 22nd (1), Bill committed a patch to the 1_0 and HEAD
branches that respects CFLAGS settings for x86-32 platforms,
specifically to address this problem on 32-bit Debian. A similar problem has been reported on
Fedora Core 5. To avoid this error, use the following command to make Evergreen:
<code>
CFLAGS=-D_LARGEFILE64_SOURCE make
</code>

=====Problem with autogen.sh: Can't call method "opac_visible" =====
====Problem====
When running ''autogen.sh'' to generate the required catalogue files, you receive the following output:
<code>Updating fieldmapper
Updating web_fieldmapper
Updating OrgTree
removing OrgTree from the cache...
Updating OrgTree HTML
Can't call method "opac_visible" on an undefined value at org_tree_html_options.pl line 28.
Done</code>
====Solution====
Open your ''opensrf.xml'' file and ensure that the value of the ''<driver>'' elements in the ''/opensrf/default/apps/open-ils.cstore/app_settings'' and the ''/opensrf/default/apps/open-ils.reporter-store/app_settings'' sections is ''pgsql'', not ''Pg''. The driver for any applications with ''<language>C</language>'' must be ''pgsql'', which specifies the corresponding libdbi / libdbdpgsql drivers written in C.
