on terminal try to see which shared libraries are found with the "ldd" utility : <br> $ ldd my_program<br><br>The path to shared librairies could be configured with the /etc/ld.so.conf file. Standart paths are "/usr/lib" and "/usr/local/lib". If you change theses paths you need to run "/sbin/ldconfig" or re-run your terminal to take this change into account. <br>
Another way is to copy or sym-link your librairies on the same directory that your program/executable.<br><br>REM : PROJ_LIB is not the directory of the .so file, but the path to the data file ( the epsg / nad27 files for example). <br>

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

points to that directory. Permissions are such that the .so is
rw.</font></span></div>

( debian and ubuntu) and don't have any specific problems. <br>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.<br>b) Concerning
ENV variable. I know two of them and one is needed in order to find data file.
<br>PROJ_LIB : path to your proj data file ( nad, epsg etc..)<br>PROJ_DEBUG :
if set to 1 make proj4 more verbose.<br><br>Hope it's helpful.<br><br>Nicolas

<div><span><font face="Arial" size="2">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?</font></span></div>
