thank you for your time.

Using binaries from postgresqls.org:

yum install https://download.postgresql.org/pub/repos/yum/9.6/redhat/rhel-7-x86_64/pgdg-centos96-9.6-3.noarch.rpm
yum install postgresql96-server postgresql96-contrib postgresql96-devel
yum install gcc gcc+c++ openssl-devel libssh-devel
tar zxf netxms-2.1-M3.tar.gz
cd netxms-2.1-M3
./configure --prefix=/opt/netxms --with-server --with-pgsql=/usr/pgsql-9.6
make -j16 && make install

Using PG from EnterpriseDB:

./postgresql-9.6.2-4-linux-x64.run # installed into default /opt/PostgreSQL/9.6
yum install gcc gcc+c++ openssl-devel libssh-devel
tar zxf netxms-2.1-M3.tar.gz
cd netxms-2.1-M3
./configure --prefix=/opt/netxms --with-server --with-pgsql=/opt/PostgreSQL/9.6
make -j16 && make install

didn't had the patience to wait.
i have installed centos 6.9 x64 with enterprisedb's postgresql v9.5.6 and everything works like a charm.
something is not working with centos7 and i would appreciate if you find out what is the problem.

i have removed yum installed postgres and i have reinstalled it from enterprisedb's installer.
running "find" found libpq.
now, if run ./configure --with-pgsql=/opt/PostgreSQL/9.5/ i get passed the libpq-fe.h but i fail in libpq
i have ran find command and found both of the files in the "/opt/PostgreSQL/9.5/include" dir

what is wrong ?
need your help a.s.a.p

i have set up a VM with the exact installation and everything is the same, can not pass the libpq.
i have removed postgres v9.5.6 from enterprisedb's installation and installed postgres from yum and i get passed the ./configure step.
does this has something to do with netxms ?
should i contact enterprisedb ?

i need an answer quick.

i have installed the postgres-devel package bundled with the centos7 install media and nothing worked, still missing libpq.
i have removed postgres9.5 and installed v9.1 and still the same error.

can you help ?
i do not want to reinstall the server with windows...

used --with-pgsql=/opt/PostgreSQL/9.5/ and didn't get the libpq-fe.h error.
now iam geting:
for PQconnectdb in -lpq... no
configure: error: libpq is require for PostgreSQL support.

can you tell me what is happening ?
never had those kind of troubles in the past...
Best Regards,
Lindeamon

this, i already knew and did but it didn't work.
in the past, you told me what should be the path and i couldn't find the post in the forum.
i have entered, --with-pgsql=/opt/Postgres/9.1/lib, should have i not enter "/lib" ?

Best Regards,
Lindeamon

environment variables is not needed, you need only libpq-fe.h in include path, and libpq.so in library path. You can specify path to your PostgreSQL installation in --with-pgsql configuration option, like

./configure --with-pgsql=<postgres install dir>

thank you for the reply. centos is packed with a different version of postgres then i have installed, does it matter ?
also, i have found the file under <postgres install dir>/include, do i still have to install the devel package ? do i need to "export" some env. variables ?

Best Regards,
Lindeamon

make sure you have package postgresql-devel installed.

Best regards,
Victor
