Re: [Boost-users] Linker warning LNK4217: locally defined symbol _ imported in function _

OK, I learned about auto_link and the #pragma's in the headers that automagically locate the correct .lib, but they aren't working. The linker now complains about not being able to find libboost_program_options-vc90-mt-s-1_40.lib, whereas I have only *-vc100-* - strange, since I built boost from the exact same (Visual C 9.0) terminal window right before trying to build my app. The specific error is: LINK : fatal error LNK1104: cannot open file 'libboost_program_options-vc90-mt-s-1_40.lib' Any ideas? Thanks in advance. On Wed, Oct 14, 2009 at 5:40 PM, Yang Zhang wrote:

I'm building the below tiny boost app with the WDK (note that I'm *not* building a driver or anything kernel-mode, just a regular userland C++ app), but I'm getting the following errors when linking with the boost libraries that I built earlier using bootstrap and .\bjam (from the same terminal window). Anyone know what the problem is, and how I might fix or work around it?
