I have always built boost (up to 1.47.0) using the following command line: bjam -j 8 --without-mpi --without-python --build-dir=vc100-bld-64-bit --build-type=complete --toolset=msvc-10.0 architecture=x86 address-model=64 --stagedir=64-bit-vc100 debug-symbols=on debug-store=database stage Now, when I specify the debug-store=database option in the command line above, the build fails and gives me errors as can be seen at the bottom of the following build output excerpt: ----------------------------------------------------------------------------------------------------------------- ...patience... ...patience... ...patience... ...patience... ...found 9190 targets... ...updating 3251 targets... common.mkdir 64-bit-vc100 common.mkdir 64-bit-vc100\lib common.mkdir vc100-bld-64-bit\boost\bin.v2\libs\math\build common.mkdir vc100-bld-64-bit\boost\bin.v2\libs\math\build\msvc-10.0 common.mkdir vc100-bld-64-bit\boost\bin.v2\libs\math\build\msvc-10.0\debug common.mkdir vc100-bld-64-bit\boost\bin.v2\libs\math\build\msvc-10.0\debug\address-model-64 common.mkdir vc100-bld-64-bit\boost\bin.v2\libs\math\build\msvc-10.0\debug\address-model-64\architecture-x86 common.mkdir vc100-bld-64-bit\boost\bin.v2\libs\math\build\msvc-10.0\debug\address-model-64\architecture-x86\debug-store-database common.mkdir vc100-bld-64-bit\boost\bin.v2\libs\math\build\msvc-10.0\debug\address-model-64\architecture-x86\debug-store-database\link-static common.mkdir vc100-bld-64-bit\boost\bin.v2\libs\math\build\msvc-10.0\debug\address-model-64\architecture-x86\debug-store-database\link-static\runtime-link-static compile-c-c++-pch vc100-bld-64-bit\boost\bin.v2\libs\math\build\msvc-10.0\debug\address-model-64\architecture-x86\debug-store-database\link-static\runtime-link-static\pch.pch pch.pch.cpp compile-c-c++ vc100-bld-64-bit\boost\bin.v2\libs\math\build\msvc-10.0\debug\address-model-64\architecture-x86\debug-store-database\link-static\runtime-link-static\assoc_laguerre.obj assoc_laguerre.cpp libs\math\build\..\src\tr1\assoc_laguerre.cpp(6) : error C2858: command-line option 'program database name (/Fde:\dev\devel\libs\boost\boost_1_48_0\vc100-bld-64-bit\boost\bin.v2\libs\math\build\msvc-10.0\debug\address-model-64\architecture-x86\debug-store -database\link-static\runtime-link-static\libboost_math_tr1-vc100-sgd-1_48.pdb)' inconsistent with precompiled header, which used '/Fde:\dev\devel\libs\boost\boost_1_48_0\vc100.pdb' libs\math\build\..\src\tr1\assoc_laguerre.cpp(6) : error C2859: e:\dev\devel\libs\boost\boost_1_48_0\vc100-bld-64-bit\boost\bin.v2\libs\math\build\msvc-10.0\debug\address-model-64\architecture-x86\debug-store-database\link-static\runtime-link-static\libbo ost_math_tr1-vc100-sgd-1_48.pdb is not the pdb file that was used when this precompiled header was created, recreate the precompiled header. call "c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\vcvarsall.bat" amd64 >nul cl /Zm800 -nologo @"vc100-bld-64-bit\boost\bin.v2\libs\math\build\msvc-10.0\debug\address-model-64\architecture-x86\debug-store-database\link-static\runtime-link-static\assoc_laguerre.obj.rsp" ...failed compile-c-c++ vc100-bld-64-bit\boost\bin.v2\libs\math\build\msvc-10.0\debug\address-model-64\architecture-x86\debug-store-database\link-static\runtime-link-static\assoc_laguerre.obj... ----------------------------------------------------------------------------------------------------------------- Is the debug-store=database option no longer supported?
