gcc backward support

mchitrakar · 08-26-2005, 12:07 AM

I am trying to recompile an old program using gcc. However, when I gcc it it shws error that
stream.h is not available. ( stream.h, a system file specified as always at #include <sys/stream.h> )
When I tried to find it , it was located at /usr/include/c++/3.2/backward/stream.h.
thus, either gcc is not able to locate stream.h or that I have missed a point somewhere. How
can I specify the system file-stream.h into gcc compiler?

In the source, you should find something like:

Code:

#include <sys/stream.h>

change it to:

Code:

#include "/usr/include/c++/3.2/backward/stream.h"

thank you very much. I guess I ought to do that. But unfortunately, there are many *.c where it has to be changed. that would be a sure good finger-exercise for me.
well....or perhaps i can grep and replace each by one u recommended. can I use following?
grep "#include <sys/stream.h>" | cat #include<...blah...blah >

well...hmmm...you could, but you wouldn't get the desired effect.

The "cheater" way around this would be to symlink stream.h into a place that CC looks. I would think if you created a sys directory in /usr/include and then symlinked:

Code:

#> ln -s /usr/include/c++/3.2/backward/stream.h /usr/include/sys/

give that a shot. see if that works. If not, you may need to change all the files.
