Re: [Help-gsl] GSL using a Makefile

[Viswakula, Sameera D.]

When I run just
    g++ -w -O4 -I ./ -o vsd_nbPoi *.cpp 
from the command line, I am getting this error



address@hidden Poisson]$ g++ -w -O4 -I ./ -o vsd_nbPoi *.cpp
/tmp/ccWSsdjU.o: In function `main':
vsd_nb.t.cpp:(.text+0x11b): undefined reference to `gsl_cdf_chisq_P'
collect2: ld returned 1 exit status


but in my vsd_nb.t.cpp (my diver file) I have included 
#include <gsl/gsl_cdf.h>  //for GSL

PS. gsl_cdf_chisq_P is defined in gsl_cdf.h

Thanks,

What error messages do you get?  Does 'gsl-config --cflags' work from your 
command line?

When you run just
    g++ -w -O4 -I ./ -o vsd_nbPoi *.cpp
from the command line, does it fail first with a message saying some GSL header 
is missing?  Or does something else happen?
