I am trying to build boost-1.42.0 with visual studio 2005 and getting the following error: assoc_laguerre.cpp libs\math\build\..\src\tr1\assoc_laguerre.cpp(6) : error C2858: command-line opt ion 'program database name (/Fdc:\toolchain\src\boost-1.42.0\build-win32-vc80-de bug\boost\bin.v2\libs\math\build\msvc-8.0\dbg\dbg-str-dtbs\lnk-sttc\thrd-mlt\lib boost_math_tr1-vc80-mt-gd-1_42.pdb)' inconsistent with precompiled header, which used '/Fdc:\toolchain\src\boost-1.42.0\boost_1_42_0\vc80.pdb' libs\math\build\..\src\tr1\assoc_laguerre.cpp(6) : error C2859: c:\toolchain\src \boost-1.42.0\build-win32-vc80-debug\boost\bin.v2\libs\math\build\msvc-8.0\dbg\d bg-str-dtbs\lnk-sttc\thrd-mlt\libboost_math_tr1-vc80-mt-gd-1_42.pdb is not the p db file that was used when this precompiled header was created, recreate the pre compiled header. ...failed updating 1 target... Anybody knows how to resolve this?
