Fortunately, you can protect your network from these Internet hackers by purchasing and installing a firewall. Computer Network

Hi. Just want to commiserate, and add a bit specific to gnuplot. I just had the same problem trying to install gnuplot with gdlib from source. Exact same problem. I figured it out, and then was able to find your note (searching without the LIBICONV didn’t help much).

This was after having another problem with the gnuplot configure script failing to find png support because in the configure test, it would build without including libpng12. I’m going to go ahead and add some keywords so maybe the next sap will find this sooner:
gnuplot libgd gdlib “undefined reference to png_”
The solution to this, for me, was to force libpng12 linking by adding ‘LDFLAGS=-lpng12′ to my ./configure command.

There’s no need for the call to exp2f(), this does the same thing:

br += (val & 1) << (len – i – 1);

Comment on From python to C(pp) by ingeneur

@rama actually, the whole thing is a one time run and that is why we chose to use python in the first place. But during construction and verifying that your algorithm is right, you might want faster results! btw, the graphs are so large that even C segments with OutOfMemory on a 2G ram machine! We just need to do things in a phased manner and python will be back in action!!

I think youve made the right choice. its been three years since i used STL (since first year in grad school) and my C expertise is hopeless anyway. if its just a one time run, it should not matter whether it takes 1 hr to run (python) or 40 mins(C). again i dont know what your context is.
