Thread: GSL onto postgresql server 9.2
Hello, colleagues !
I have to put some C-language functions onto postgresql server 9.2. These functions are used GSL software library http://www.gnu.org/software/gsl/. In Makefile for these functions I wrote LD_FLAGS = ... -lgsl, On some source-based Linux distributions such as gentoo linux these functions successfully installed onto server, but on rpm-based distributions such as fedora and others does not. gsl library has to be compiled from sources, because some specific distributions does not have this one and rpm-installation of this library does not allowed. Error message is "error <mylibrary>.so cannot load libgsl.so.0 no such file" despite of gsl library was installed onto /usr/local, library files are installed into /usr/local/lib. Where is the problem in postgresql or distribution ?

Where is the problem in postgresql or distribution ? Read "man ld", the description of "search paths to locate required shared libraries". /usr/local/lib is not automatically searched. I would either install the library in /usr/lib, link the shared object with -Wl,-rpath,/usr/local/lib or put /usr/local/lib into /etc/ld.so.conf and run ldconfig. Yours, Laurenz Albe
Thanks a lot.
I have compiled gsl with prefix=/usr and this is quite acceptable for us.

required shared libraries".
/usr/local/lib is not automatically searched.
I would either install the library in /usr/lib,
link the shared object with -Wl,-rpath,/usr/local/lib
or put /usr/local/lib into /etc/ld.so.conf and run
ldconfig.
