Executable not found from /usr/local/bin
 

Hi,

I installed ghostscript via yum package manager. Later I wanted a newer version of ghostscript and compiled it from source. "make install" placed the gs executable file under /usr/local/bin/gs. This works if I run the command with absolute path, but if try to run gs, the shell will output

"-bash: /usr/bin/gs: No such file or directory"

if I echo the path variable it will display

/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin

If i run whereis it will give me the correct path
gs: /usr/local/bin/gs

How do I make it work so that typing "gs" will run the executable file from the /usr/local/bin/gs?

(I am using Centos 6)

Thanks.

what will say which gs and type gs ?

Your environment variable PATH does not include /usr/local/bin as one to be searched for commands. What you have to do is edit your profile (or the /etc/profile) and add that path.

then the next time you login/start a command window, bash will now search /usr/local/bin for commands as well as what it was searching before.

redhat based systems normally do not have /usr/"local" in the system path

if you WANT!!! to use that location YOU need to add that location to $PATH

so you installed ghosetscript to a FOLDER in /usr/local/bin
"/usr/local/bin/gs"

well you will need to add MANY MANY locations to a few DIFFERENT paths then
be carfull on HOW you build source

it can CAUSE ALL KINDS OF EXTRA WORK if you do not think it through

Actually, you don't need the PKG_CONFIG_PATH or C_INCLUDE_PATH unless you are rebuilding something that plugs into ghostscript.

And the easiest way to deal with the library is to add a configuration file to /etc/ld.so.conf.d that gives the path. Rerun ldconfig and everything is taken care of.
