GNU scientific library linking

Question

I have installed GNU scientific library (http://www.gnu.org/software/gsl/) which is located in /home/usr/gsl-1.9 and installed statistical programme in /home/usr/statprog

when I tried to compile it, this happens:

$ cd home/usr/statprog 
$ make
gcc -O3 -Wall -Wshadow -pedantic D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -DVER32 -I/opt/local/include/ -L/opt/local/lib/ -c -o mlRho.o mlRho.c
gcc: error: D_GNU_SOURCE: No such file or directory
make: *** [mlRho.o] Error 1

It says no such file or directory. How to link GNU library to this statprog?

Answer 1

There's a dash (-) missing in the command before D_GNU_SOURCE. Passing -D_GNU_SOURCE to the compiler is equivalent to adding #define _GNU_SOURCE at the start of the c file.

It looks like the Makefile is corrupted somehow. Try

find . -type f -exec grep -lZ D_GNU_SOURCE {} + |
  xargs -r0 perl -pi -e 's/-*D_GNU_SOURCE/-D_GNU_SOURCE/g'

and run make again. However it's likely that something more fundamental is wrong here for that error to have crept in in the first place.
