Re: AW: Compling Error gsu 2.6

[John D Lamb]

Dear Benedikt:

I also use Ubuntu (20.04) and have not had problems with GSL linking.

The -L/usr/local/lib should be telling g++ to look in /usr/local/lib. 
But you seem to have installed gsl in ~/Programme; so it might be more 
sensible to use -L.. instead (I haven’t tested it).

Ubuntu already has GSL in the repositories; so you might just install 
it. If you are using any recent version you should have stats available. 
And if GSL is installed in the Ubuntu default location, g++ will find 
libgsl.so etc without any extra effort.

If you are using C++ and want to use GSL stats on, for example, 
std::vector<double>s, you could try 
https://sourceforge.net/projects/ccgsl/, which will let you use gsl 
stats functions with objects C doesn’t know about. But solve the 
location problem first: ccgsl doesn’t
need extra libraries but it does need somewhere to install header files.
