I'm trying to install osm2pgrouting. I have installed all the required packages and I also have changed the #include "libpq-fe.h" to #include postgresql/libpq-fe.h" in the src/Export2DB.h. However when I'm trying to do "make", I get this error:

I had this error on a Linux machine that did not have postgresql installed.

The solution was to simply install libpq-dev via the following command:

sudo apt-get install libpq-dev

The /user/include/postgresql/ directory and libpq-fe.h were created just fine, and when I did the make / make install, there were no issues.

Here's the thread I found the solution on: https://stackoverflow.com/questions/6040583/cant-find-the-libpq-fe-h-header-when-trying-to-install-pg-gem
