Hello there,

this is my first post on this list (which until recently I didn't know it 
existed); I looked through the archives but didn't find a reference to 
this problem, so here it goes.

We have been using GALib on our lab for a while, as a base for Grammatical 
Evolution, and we are extremely happy with it.

However, I recently installed 2.4.6, but now I get errors when compiling 
small programs of this kind:

int main(){
         GAGenome g;
         GASteadyStateGA ga(g);
         return 0;

g++ -c test.cc

The list of errors is quite long, but it basically comes down to this:

/usr/local/include/ga/GAParameter.h:16:27: ga/std_stream.h: No such file 
or directory

I made a global install of GALib on /usr/local. The error occurs both with 
gcc 3.3.2 and 3.4.1 . If I copy std_stream.h from the galib source 
directory to /usr/local/include/ga/, the error disappears. Is there any 
specific reason for it not to be copied with `make install`? Is my 
solution all that is needed (i.e. do you think it will create other 

Thanks in advance. Keep up the good work, we are totally addicted to GALib 
around here!

All the best,
