Hi,

I am trying to build boost.threads 1.32 statically with struct alignment set to 1.

I dug up from the documentation that this should do the trick:

bjam -sTOOLS=vc-7_1 "-sBUILD=debug <struct-alignment>1" -a -d+2

however, I don't see the alignment switch '/Zp1' on the command line :

"cl" /Zm800 -nologo /EHsc -c -DBOOST_THREAD_LIB_NAME=boost_thread -DBOOST_THREAD_BUILD_LIB=1 /Z7 /Od /Ob0 /EHsc /GR /MDd /Op Zc:forScope /Zc:wchar_t -I"..\..\..\bin\boost\libs\thread\build" -I"C:\Program Files\Microsoft Visual Studio .NET 2003\VC7\include" I"G:\boost_1_32_0"

-Fo"..\..\..\bin\boost\libs\thread\build\libboost_thread.lib\vc-7_1\debug\threading-multi\tss.obj" -Tp"..\..\..\libs\thread\build\..\src\tss.cpp"

Is there something I am missing ?

I am getting in the habit of answering to myself :

I would have answered earlier but I was on vacation :-)

Here is a patch to msvc-tools.jam that implements support for feature struct-alignment, as documented in features.jam

http://boost.org/tools/build/v1/features.jam

G:\boost_1_32_0\tools\build\v1> diff orig.jam msvc-tools.jam 81a82,87

...

flags msvc CFLAGS <struct-alignment>1 : /Zp1 ; flags msvc CFLAGS <struct-alignment>2 : /Zp2 ; flags msvc CFLAGS <struct-alignment>4 : /Zp4 ; flags msvc CFLAGS <struct-alignment>8 : /Zp8 ; flags msvc CFLAGS <struct-alignment>16 : /Zp16 ; flags msvc CFLAGS <struct-alignment>auto : ;

I'll add that in, thanks.

Is there a better way to do this ?

If by better you mean without modifying msvc-tools.jam. You could add the option generically: bjam -sTOOLS=vc-7_1 "-sBUILD=debug <cflags>/Zp1" -a -d+2 -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com -- 102708583/icq - grafikrobot/aim - Grafik/jabber.org
