[Proj] Trouble integrating Proj4 into application

[James Kilroy]

So I have my code comiling and linking fine at this point, thanks for the
assistance.  Now any pointers on how to get my application to find the .so
file?  The .so is in the same directory as the lib file and the PROJ_LIB
points to that directory.  Permissions are such that the .so is rw.
 
Thanks,
 
James Kilroy

Hi

I've done quite same thing recently ( debian and ubuntu) and don't have any
specific problems. 
a) you have to take care when including proj4 files, because it's an ANSI C
library and not a C++ lib. So, within a C++ project you have to use
proj_api.h.
b) Concerning ENV variable. I know two of them and one is needed in order to
find data file. 
PROJ_LIB : path to your proj data file ( nad, epsg etc..)
PROJ_DEBUG : if set to 1 make proj4 more verbose.

Hope it's helpful.

Hello All,
 
My name is James Kilroy and I am a brand new user of Proj4.  I have an
extensive GIS back ground so I have a good grasp of the concepts, and I have
been coding professionally (C/C++) for over 20 years.  I have installed the
code base for Proj4 on my Linux server (Fedora, very recent build).  The
build went without a hitch, all programs test out fine.  My problem is I
can't get the lib to compile into my project.  Keeps giving me lib not found
errors, though the lib is built, in place, and has proper permissions.  Are
there any specific compiler directives required or ENV variables that are
needed that I am not aware of?
 
Thanks,
 


James Kilroy
