Re: [Help-gsl] GSL using a Makefile

[Viswakula, Sameera D.]

Thanks Rhys for your quick response. I tried your approach but unfortunately it 
doesn't work.

I think the problem is my C++ project uses some of the headers and source files 
which are in the saved in my working directory. Therefore, I am getting bunch 
of errors saying that namespaces are wrong and some member functions are not 
declared.  

What should I do? 

Thanks,

The 'gsl-config' binary that GSL installs can make retrieving those values 
quite easy for Makefiles.  See below.

Try
    g++ -w -O4 `gsl-config --cflags` -o vsd_nbPoi *.cpp `gsl-config --libs` 
where those are backticks around the gsl-config bits and I've removed your '-I 
./' option as I suspect it accomplishes nothing (the compiler should look for 
includes in the local directory).

Hope that helps,
Rhys
