[Insight-users] Linking external libraries?

[Harri Tapio Jaalinoja]

Hi Luis,

thanks again for your help! read_img was indeed in libbsoft:

[hajaalin@gene hajaalin]$ cd /usr/local/bsoft/lib
[hajaalin@gene lib]$ ls
libbsoft.a  libbsoft.so*  libfftw.a  libtiff.a
[hajaalin@gene lib]$ grep read_img *
Binary file libbsoft.a matches
Binary file libbsoft.so matches
[hajaalin@gene lib]$

But the solution lay in moving the #include <rwMRC.h> away from the
extern block. The reason I put it there was a newbie guess, the code is in
C as opposed to C++. Why string.h and stdio.h were there I don't know,
I copied it from the WatershedExample.

Cheers,
Harri
