Thanks for the steps. I am thinking in a different method. I just<br>
pushed a branch cmake-postgres. In File FindPostgreSQL.cmake on line no:<br>
19, PG_VERSION is a argument passed while running cmake. ( cmake<br>
-DPG_VERSION=9.* ).<br>
<br>
* Take an argument from command line.<br>
* Modify the present FindPostgreSQL.cmake, build it until it is working<br>
properly.<br>
<br>
I am stuck here at this point. See line no: 43 (<br></span>
COMMAND${POSTGRESQL_PG_CONFIG}--version) this is giving 8.4 as<span class=""><br>
defaults. Therefore variables after this are set with 8.4, I need to<br>
somehow understand and change it.<br>
<br>
If you are free now we can discuss this.<br>

I'm working on this already. Since this is my first time on<br>
cmake and<br>
dependencies I might need some help from you guys.<br>
<br>
I'll try my best to make it working.<br>
<br>
<br>
Start with the message below and ask where you get stuck. The steps are:<br>
<br>
1. copy the FindPostgreSQL.cmake linked below to the pgrouting/cmake<br>
<br>
2. this will break the build stuff because this new script sets<br>
different variables than the existing build expects.<br>
<br>
3. sort this out and get it to build like it did before using the<br>
new script<br>
<br>
4. when it is building like before, add the variable to set the<br>
version in the commandline and and use that to set<br>
PostgreSQL_ADDITIONAL_VERSIONS and it should work.<br>
<br>
Ask specific questions if you get stuck, check in your code where I<br>
can look at it.<br>
<br>
There is a ticket for this:<br>

You probably want to start with this version of FindPostgreSQL.cmake<br>
<br>
<a href="https://github.com/Kitware/CMake/blob/master/Modules/FindPostgreSQL.cmake" rel="noreferrer" target="_blank">https://github.com/Kitware/CMake/blob/master/Modules/FindPostgreSQL.cmake</a><br>
<br>
It lets you specify PostgreSQL_ADDITIONAL_VERSIONS variable<br>
and if<br>
this is set to the version you want it will use this version if<br>
found.<br>
<br>
I think that the return variables that this script sets are<br>
different<br>
from what we expect in pgrouting so you might need to set the<br>
expected variables with the correct values also.<br>
<br>
So, I would replace the existing FindPostgreSQL.cmake with this<br>
script and then try to make it work with the existing build system,<br>
then look at reading a command line version and setting the variable<br>
above before calling find postgresql.<br>

Hi Steve,<br>
<br>
I've tried my best to update cmake/FindPostgreSQL.cmake and<br>
CMakeLists.txt, but the build was not successful. I've<br>
changed all<br>
the POSTGRES variables to 9.4, cmake executed properly, but<br>
while<br>
compiling(make) there is a error saying "Postgres.h" not<br>
found. Can<br>
you share your CMakeLists.txt and<br>
cmake/FindPostgresql..cmake. I am<br>
on the version 9.4.<br>
<br>
I think this needs to be solved for the next release. We need to<br>
the pass the postgresql version to build, like the option you<br>
said "DUSE_PG=9.x". But unfortunately it is not working<br>
right now.<br>
I'll try to read about cmake and see what I can do. I will<br>
update<br>
you.<br>
<br>
Thank you, Mani<br>

Hi,<br>
<br>
I am facing an error while building from source. This is that<br>
issue: <a href="https://github.com/pgRouting/pgrouting/issues/109" rel="noreferrer" target="_blank">https://github.com/pgRouting/pgrouting/issues/109</a><br>
<br>
How to resolve that? Changing Pg version to 9.1 in<br>
CMakeLists.txt<br>
is not working. I have 9.1 and 9.4 postgresql versions<br>
installed in<br>
my system. Help me out in resolving this.<br>
<br>
<br>
Mani,<br>
<br>
Sorry, the CMakeLists.txt files built for pgrouting 2.x were not<br>
designed for support multiple versions installed on the same<br>
system. This is a problem for me because I have 9.2, 9.3,<br>
and 9.4<br>
installed and I can only build and install on 9.4.<br>
<br>
The solution id to update the CMakeLists.txt and specifically<br>
cmake/FindPostgreSQL.cmake which so you can do something like<br>
<br>
cd build cmake -DUSE_PG=9.x ..<br>
<br>
I took a quick look at doing this a while back but<br>
cmake/FindPostgreSQL.cmake needs to be replaced and other<br>
changes<br>
are needed and I didn't have time to make the changes and get it<br>
working.<br>
<br>

<<a href="http://test-runner.pl" rel="noreferrer" target="_blank">http://test-runner.pl</a>> already support<br>
options for pg versions and ports so only the build system is<br>
broken in this regard.<br>
<br>
If you want to read up on CMake and get this working a pull<br>
request would be great!<br>
