Sandcastle is running out of memory

[dasdebas]

Hi There:
sandcastle is failing in the last steps ( CompilingHelpFile) because of no memory available error. I closed all other application, still getting same error, tried other things still fails. It might be that sandcastle is not able to process 130,255 generated html files when compiling help files. What can we do? My machine has 32GB physical memory, sandcastle process if hardly taking max ~5GB. I also tried x64 ( see the attached image), still fails. Your help is greatly appreciated. Thanks

The x64 setting applies to the platform selected for the solution/project documentation sources. SHFB is itself 64-bit so no issues there. If you're building a Help 1 file though, that is the issue since the help 1 compiler is a 32-bit application so won't use all available memory. There's nothing SHFB can do about that. Switching to website or Open XML output for standalone help are the only alternatives. Although with that many topics, Open XML probably isn't a good solution so website is the better option assuming you can host it somewhere.

Thanks a lot Eric. I was able to generate help using one of the 2 approaches you mentioned.

can 64 bit of "help 1 compiler" be integrated with SHFB? I see many posting in web due to memory limit issue, integrating 64 bits of "help 1 compiler" will help a lot. Thanks

As far as I know there is no 64-bit version of the help 1 compiler (part of the HTML Help Workshop). It's really old and 32-bit only.

@dasdebas, you might try the HTML Help 1 Compiler from Visual Studio resources, see my HowTo issue #1060.

They're still the same 32-bit components so it likely won't make any difference.

It could be a newer version might manage the memory better than an old one. This was the intension behind.

And there is a 2GB and 4GB border in 32 bit. A vendor of a CAD application was able to switch from 2GB usage to 4GB of its 32 bit application with a compile setting.
