Обсуждение: Help needed building syscopg2
I am trying to install psycopg2 from source in Centos 6.7 x86_64, with Python 3.4.3 and Postgresql 9.4
I have overcomed and resolved the documented ‘gotchas’:
a) Access to pg_config >> Added “export POSTGRESQL_HOME=/usr/pgsql-9.4; pathmunge $POSTGRESQL_HOME/bin” to /etc/profile.d
b) Missing libpq-fs.h, pg_config_ext.h, postgres_ext.h, libpq-fe.h >> All moved to psycopg2-2.6.1 directory
Currently the build is failing the “python setup.py build” at gcc. The compiler complains about a “-lpq” switch (Just after “-o” switch. I am not being able to resolve this problem. Compile messages follows:=========================================creating /root/psycopg2-2.6.1/build/lib.3.4creating /root/psycopg2-2.6.1/build/lib.3.4/psycopg2gcc -pthread -shared -Wl,-rpath /usr/local/lib build/temp.linux-x86_64-3.4/psycopg/psycopgmodule.o build/temp.linux-x86_64-3.4/psycopg/green.o build/temp.linux-x86_64-3.4/psycopg/pqpath.o build/temp.linux-x86_64-3.4/psycopg/utils.o build/temp.linux-x86_64-3.4/psycopg/bytes_format.o build/temp.linux-x86_64-3.4/psycopg/connection_int.o build/temp.linux-x86_64-3.4/psycopg/connection_type.o build/temp.linux-x86_64-3.4/psycopg/cursor_int.o build/temp.linux-x86_64-3.4/psycopg/cursor_type.o build/temp.linux-x86_64-3.4/psycopg/diagnostics_type.o build/temp.linux-x86_64-3.4/psycopg/error_type.o build/temp.linux-x86_64-3.4/psycopg/lobject_int.o build/temp.linux-x86_64-3.4/psycopg/lobject_type.o build/temp.linux-x86_64-3.4/psycopg/notify_type.o build/temp.linux-x86_64-3.4/psycopg/xid_type.o build/temp.linux-x86_64-3.4/psycopg/adapter_asis.o build/temp.linux-x86_64-3.4/psycopg/adapter_binary.o build/temp.linux-x86_64-3.4/psycopg/adapter_datetime.o build/temp.linux-x86_64-3.4/psycopg/adapter_list.o build/temp.linux-x86_64-3.4/psycopg/adapter_pboolean.o build/temp.linux-x86_64-3.4/psycopg/adapter_pdecimal.o build/temp.linux-x86_64-3.4/psycopg/adapter_pint.o build/temp.linux-x86_64-3.4/psycopg/adapter_pfloat.o build/temp.linux-x86_64-3.4/psycopg/adapter_qstring.o build/temp.linux-x86_64-3.4/psycopg/microprotocols.o build/temp.linux-x86_64-3.4/psycopg/microprotocols_proto.o build/temp.linux-x86_64-3.4/psycopg/typecast.o -L/usr/local/lib -L/usr/pgsql-9.4/lib -lpython3.4m -lpq -o /root/psycopg2-2.6.1/build/lib.3.4/psycopg2/_psycopg.cpython-34m.so/usr/bin/ld: cannot find -lpqcollect2: ld returned 1 exit statuserror: command 'gcc' failed with exit status 1make: *** [/root/psycopg2-2.6.1/build/lib.3.4/psycopg2/_psycopg.so] Error 1=============================================================
I will Appreciate any suggestions.

It seems it didn't find libpq.so. Do you have the file in /usr/pgsql-9.4/lib? -- Daniele
Hi Danielle, Yes, I have libpq.so.5.7 in directory /usr/pgsql-9.4/lib. In the same directory there is also a soft link named libpq.so.5 which is mapped to libpq.so.5.7 Any other ideas ?

Hi Adrian, That might be the problem. But how do I get the -dev ?

Maybe because it is called "postgresql94-devel" ?
