Hi,

I'm having trouble compiling a code fragment. After running the makefile, I
try to run the program wich then gives the the following error?

dehann:/home/dehann/workspace/rtPP_AD# make
gcc -I/usr/xenomai/include -D_GNU_SOURCE -D_REENTRANT -D__XENO__
-L/usr/xenomai/lib -lpthread -lnative main.o -o main -lm
dehann:/home/dehann/workspace/rtPP_AD# ./main
./main: error while loading shared libraries: libnative.so.1: cannot open
shared object file: No such file or directory

the libnative.so.1 file is in the /usr/xenomai/ directory. Thanks in
advance!

Dehann

There are several ways out:
- use ld -rpath option (see ld manual);
- use the LD_LIBRARY_PATH environment variable;
- add /usr/xenomai to /etc/ld.so.conf and re-run ldconfig.

According to internet, -rpath is the cleanest solution. And if you look
at xenomai examples makefiles, they use -rpath.
