HELP!! gem install pg failed on opensuse 10.3

created an issue

Hi,

This is my first time install pg gem on linux box and it is failed. The only error I saw is the libpq-fe.h not found. Below is the command I use and the output of the command:

{{{

/export/home/invantest/tools/ruby/current/bin/gem install pg -- --with-pg-config=/export/home/invantest/tools/pgsql/8.3.3/bin/pg_config

When I do a ls on the include path, it show that the file is really exist:

{{{

ls /export/home/invantest/tools/pgsql/8.3.3/include/libpq-fe.h /export/home/invantest/tools/pgsql/8.3.3/include/libpq-fe.h }}}

I have no idea what else missing.

  • Ruby version is 1.8.7
  • Postgresql version is 8.3.3

I also included the mkmf.log for your reference. I am very appreciate for your help.

    On debian and ubuntu, it looks like libpq-fe.h is provided by the package "libpq-dev". Can you try installing that package (or equivalent on your distribution)?

    Jeff, it looks like he has Postgres installed in his home directory, and the `mkmkf.log` confirms that the include dir from the installation is being included in the CPPFLAGS.

    syliang, would you mind testing something out for me? Create a file called `test.c` or something and paste this into it:

    #include <libpq-fe.h>
    

    Then run this command:

    gcc -E -I. -I/export/home/invantest/tools/ruby/1.8.7/lib/ruby/1.8/i686-linux -I. \
      -D_FILE_OFFSET_BITS=64  -I/export/home/invantest/tools/pgsql/8.3.3/include \
      -g -O2    test.c -o test.i
    

    and either reply with the output, or attach it if you prefer. Thanks!

    Hi Guy,

    I know what is the error already. I done a stupid mistake that I didn't notice the machine did not install with GCC. After I install the GCC, pg gem install successful. The error seem to be not reflect the real error but anyway it works. Thanks and sorry guys for wasting your time.
