Compile Macro with GSL libraries

In ROOT 5, you need to use ACLiC and you need to load the system provided gsl manually so, try: root [0] gSystem->Load("/usr/lib/libgsl"); // load the system provided gsl root [1] .x test.cxx++ In ROOT 6, there is no need to use ACLiC and your macro can automatically load the system provided gsl, if you add R__LOAD_LIBRARY(libgsl) right in the beginning of your macro. If you have the “builtin_gsl” (i.e. when “root-config --has-builtin_gsl” returns “yes”), you may try: root [0] gSystem->Load(…

Problem on using GSL on root

Rename “main(int argc,char const *argc[])” into “test(void)”, then try: root [0] gSystem->Load("/usr/lib/libgsl.so"); // see: locate libgsl.so root [1] .x test.c++ and / or: root [0] gSystem->AddLinkedLibs("-lgslcblas -lgsl"); // see: gsl-config --libs root [1] .x test.c++
