Hi All
I am new to Lazarus and having a few problems with whatelse seems to be an
excellent development environment. I have past experience with Delphi and am
hoping to be able to use Lazarus for a major upcomming open source project.
Today I have everything (fpc-2.2.5 / lazarus-0.9.28.2 / zeos-6.6.5-stable)
all working under XP
With Fedora 11 (fpc-2.2.2 / lazarus-0.9.26.2 / zeos-6.6.5-stable) (I am
using slightly older versions that distribute with Fedora because I had some
compilation problems with the latest packages)
when I try to set the connected property for the zeos Zconnected component
to true, I get an error saying that the libmysqlclient.15.so amd
libmysqlclient.so cannot be found. These libs are installed under
/usr/lib64/mysql
I have tied to use the shell path commands to export this PATH and find no
change.
How do I tell either fpc or lazarus or zeos where these libs are? I have
looked at the lazarus environment options and do not see an area to make
this change.
It's not fpc or lazarus that's responsible for this, but ld. You can add directories to the environment variables LD_LIBRARY_PATH and LD_RUN_PATH. Making a symlink in /usr/lib is a more permanent solution. There are more ways, but you can read the man pages for ld (see -rpath and -rpath-link options) and ld.so to learn more about this.
