I'm getting following error in VC++ 6.0

fatal error C1060: compiler is out of heap space

Any help?

It is one of those infamous errors of MS for which they are feared all over the world.

Use /Zm switch and keep playing with its value from 100 to 1000

The syntax would be /Zm100
Either add it via VC++ Project->Settings go on Link tab and add above in the last of Project Options window.

Or alternatively you could also edit the .dsp file directly and stick in there.

Bea careful while messing up with .dsp file

/Zm400 worked for me
Thank you
