Обсуждение: libpg++ under SUSE Linux 7.0 (problem with link os.h)

Hi all,

I installed Postgres with the SUSE distribution 7.0 and it works fine.

However if I try to use the libpg++ library and link it to my C++ programm I
receive some error message about the include file.

The "libpg++.h" contains several other include files which again contain
other include files. I went through the include files and came to a link
called "os.h" which links to "linux.h".

I could not find this "linux.h" on my system and was wondering whether this
file should be part of my linux distribution or comes with Postgres?

Where should I link os.h to?


Thanks for the help

Markus

I believe this is referring to the linux.h in the linux kernel source
code.  If you don't have the kernel source installed and can do so easily,
do it.  If not, maybe someone else has a trick up their sleeve.

No, it's referring to the Postgres file src/include/port/linux.h.  There
is a packaging error in the 7.0 RPMs that causes them to create the
installed os.h as a symlink, rather than a copy of the port .h file as
it should be.

Markus, you can replace os.h with the attached (7.0's linux.h file).
