2.3 Shared Libraries

To run a program linked with the shared version of the library it may be necessary to define the shell variable LD_LIBRARY_PATH to include the directory where the library is installed. For example,

LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH ./app

To compile a statically linked version of the program instead, use the -static flag in gcc,

gcc -static app.o -lgsl -lgslcblas -lm
