Question

This is my program:

#include </usr/local/include/GL/glut.h>

int main(int argc, char **argv) 
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DEPTH | GLUT_DOUBLE | GLUT_RGBA);
    glutInitWindowPosition(100,100);
    glutInitWindowSize(320,320);
    glutCreateWindow("Lighthouse3D- GLUT Tutorial");
}

Compiled with:

g++ -lglut -L/usr/local/lib/ -o start
start.cpp;./start

Error shown:

./start: error while loading shared
libraries: libglut.so.3: cannot open
shared object file: No such file or
directory

The file is present.

bashprompt> locate libglut.so.3
/usr/local/lib/libglut.so.3
/usr/local/lib/libglut.so.3.9.0

Had also tried:

LD_RUN_PATH=”/usr/local/lib/”
g++ -lglut -LLIBDIR -o start start.cpp;./start
with no luck.

These were the messages shown while installing (if this helps):

———————————————————————- Libraries have been installed in:
/usr/local/lib If you ever happen
to want to link against installed
libraries in a given directory,
LIBDIR, you must either use libtool,
and specify the full pathname of the
library, or use the -LLIBDIR' flag
during linking and do at least one of
the following:
- add LIBDIR to theLD_LIBRARY_PATH’ environment variable
during execution
– add LIBDIR to the LD_RUN_PATH' environment variable
during linking
- use the-Wl,–rpath -Wl,LIBDIR’ linker flag
– have your system administrator add LIBDIR to `/etc/ld.so.conf’
See any operating system documentation
about shared libraries for more
information, such as the ld(1) and
ld.so(8) manual pages.

Answer 1

Your LD_RUN_PATH attempt was very close, but it should be LD_LIBRARY_PATH:

export LD_LIBRARY_PATH=/usr/local/lib
./start

This tip from the installer is also handy:

have your system administrator add LIBDIR to `/etc/ld.so.conf’

If you did that, you wouldn’t need to do the LD_LIBRARY_PATH thing.
