Re: [Help-glpk] Always running time error : " error while loading shared libraries: libglpk.so.0:"

[Guanyao Huang]

Actually I already make install but I didnt post in the email.
OK.
Now:
sudo ./configure --prefix /usr
sudo make install prefix=/usr

Then make check works.
However, still there is a running time error for my program:
address@hidden TestLP]$ ./TestLP
./TestLP: error while loading shared libraries: libglpk.so.0: cannot
open shared object file: No such file or directory

If I dont specify the prefix /usr but let it to be /usr/local/, there
is still the same error.

As I said, global variables are already defined as:
declare -x LD_LIBRARY_PATH="/usr/lib"
declare -x LD_RUN_PATH="/usr/lib"
declare -x LIBDIR="/usr/lib"

I strongly suspect that it is a problem of  my Makefile for my own program.

Thanks.
