Compiler Warning question

[BubbaDave]

Hi,

My problem is I get the following message when I compile my code.

Cannot create pre-compiled header; write failed

The help file says that this occurs when the hard drive is full...I have 65GB available.

I am using BCB6 on a WinXP machine. I have my settings to use pre-compiled headers. I can turn it off, but I would like to get the extra compile speed by caching the headers.

Any help with this will be appreciated. Thanks.

It could be that you need to move the #pragma hdrstop.

In my unit-files i have:
#include <vcl.h>
#pragma hdrstop

and then my own includes and extras and such. Try set that configuration in all of your files in the project and see if it makes a change.

The files are still cached and only files in need of recompiling will be compiled.

Keep making it perfect and it will end up broken.

I see this alot on my older code that was orginally compiled under BCB3 & 5. It is just a warning and everything should work correctly. Try Totte's suggestion and let us know what happens.

Thanks, Totte. I checked the placement of the #pragma hdrstop. ..it was in the same relative location as your example, so I tried moving it to the top of the file. It worked like a charm. Now I am going to go to the help files and books to learn what the hdrstop pragma is!

Thanks again.

If it aint broke, fix it till it is.

Great!

But move the
#include <vcl.h> up too, the
#pragma hdrstop is some definition of Headerstop, i take it that it's some stop for the "build-in" headers. I always fill in below those lines and i recommend the same for you.

See if this helps:

just a mention about pre compiled headers. borland have stated that using them with bcb6 can increase compile times by up to a third. ie bug. and suggests you clear them out of your bin folder.
