Thread: help installing boos. Selecting *variants*?

Hi,

I'm installing boost for visual studio 2008, using the boost installer.

It's asking which build variants to install by default.

The choices are:
Multithread Debug, DLL
Multithread, DLL
Multithread
Multithread Debug
Multithread Static runtime
Multithread Debug, Static runtime
Single thread, Static runtime
single thread Debug, static runtime

What do I want?

well i just went ahead and installed everything (for vs9.0 anyway)

but I have another off-topic question

why do i sometimes get the following error when building with visual studio?

Code:

Error	1	fatal error LNK1000: Internal error during IncrCalcPtrs	Program.obj	,

it doesn't seem to do anything, because another sucessive build, build just fine
