It cannot find the gsl library. What happens when you try to install gsl locally as suggested? Azim

Something similar. gsl1.16 is downloaded and compiled as suggested:

This time it cannot find the math library to link it in. the "-lm" tells the compiler to link in the math library. Maybe move the "-lm" to the end of the compilation command. Hopefully that solves the problem.

gcc -I ../gsl-1.16 treeBreaker.c ../libs/knhx.c -o treeBreaker ../gsl-1.16/.libs/libgsl.a -lm

That worked, thanks!
