[postgis-users] Making shp2pgsql using iconv in /usr/local?

[Larry Shaffer]

strk and Mike,

Thanx for all your help. Problem is solved! No special make FLAGS needed.

After checking into <http://mapserver.gis.umn.edu/bugs/show_bug.cgi?
id=909> as noted by Mike, it got me to thinking... What do you do when
two 'similar' libraries are not playing nice when installed in normal
directories of your PATH? Un-install, then re-install the lesser of the
two into a non-standard location. Viola! I re-installed the standalone
libiconv-1.9.1 into /usr/local/my_iconv/ instead of the default /usr/
local and that did the trick. I was then able to make PostGIS's loader
using the /usr iconv with only 'make' as the command (with USE_ICONV ?=
1) and it worked as advertised. Also, I was able to compile other
installs that were having the same problem caused by finding/referencing
multiple installs of iconv (somehow), ala ./configure errors:

undefined reference to `libiconv_open'
undefined reference to `libiconv'
undefined reference to `libiconv_close'

Why do I need the two iconv installs? Well, I'm installing at the /usr/
local level for all users on my managed server, with the /usr level
installs managed by my provider. I could have used the /usr install of
iconv for everything, if that would have worked. It didn't. It worked
for libxml2, fontconfig, and PostGIS, but NOT for PHP. PHP said I had to
reinstall /usr/iconv. ?Huh?

Needless to say, I had to re-compile a bunch of installs that used the /
usr/local iconv. :(

So, I just installed the standalone libiconv-1.9.1 into a non-standard
directory and referenced it in the ./configure of software that seemed
to need it, while I left alone installs that could cope with the /usr
iconv if they were not 'cross-linked' into something down the road, like
PHP (had this problem with libxml2 if libxml2 used the /usr iconv) or
Mapserver.

Again, thanx for the help. Everything, including PHP, and Mapserver now
work, though I haven't tested localization support. I have not had time
to test PostGIS (or its loader), just install it and import its SQL into
a PostgreSQL db.

To sum up: Installing the standalone libiconv-1.9.1 into /usr/local if
you already have iconv installed under /usr is not a good idea (at least
on my server), seemingly regardless of whether you can specify --with-
iconv=/usr/local while installing.

I don't think I know enough about such things to really help debug that.
I can try if you need.
