[buid] disabling specific warnings
Can I pass a command line argument of some sort to tell Boost.Build V2 to disable some specific MSVC warnings?

should work.
It doesn't. I tried bjam --toolset=msvc-8.0 cxxflags=/wd4251 but bjam spits errors about invalid arguments and aborts without building anything. So I tried bjam --toolset=msvc-8.0 --cxxflags=/wd4251 and it was better, but not good enough. It did compile this time, only warning 4251 was still not disabled. So I tried bjam -d+2 --toolset=msvc-8.0 --cxxflags=/wd4251 to show the actual command executed (as suggested by bjam --help) but I couldn't figure anything from it. It seems 'cl' is passed some .rsp files, instead of .cpp file (as I expected). The command line didn't include '/wd4251', but maybe it's because the usage of the .rsp file (which I have no idea what it is). To conclude, I still can't disable a warning...

What are the *exact* error messages?

No, --cxxflags is not a valid option. Only cxxflags=... will have anything remotely like the right effect. The other one will be ignored.

Yeah, so look at the commands that build the .rsp file. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com Don't Miss BoostCon 2007! ==> http://www.boostcon.com

As someone else pointed out, it would be nice if wrong options would generate an error message rather than being ignored...

Actually, that's not the whole output. The first lines were the usual regex Unicode stuff: Building Boost.Regex with the optional Unicode/ICU support disabled. Please refer to the Boost.Regex documentation for more information (don't panic: this is a strictly optional feature). The errors above were printed after. Don't know if it's of any help...

I saw the same thing yesterday when trying to use 'cxxflags'. Here's the version output from bjam which I downloaded from Sourceforge at the same time I got the 1.34.0 source code: Boost.Build V2 (Milestone 11) Boost.Jam 03.1.14 The file date is 4/30/2007 which co-incides with the package date on Sourceforge. -Chris

OK, try this: bjam --toolset=msvc-8.0 --without-python cxxflags=-wd4251 stage I think it's a problem in BBv2 that "/" is given special meaning in property values. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com Don't Miss BoostCon 2007! ==> http://www.boostcon.com

Yes, that works. Thanks a lot. Although I have to admit that I find it weird that cxxflags doesn't pass its value as-is to the compiler...

Oops, I spoke too soon. It doesn't work. I guess I got confused last time, and missed the warning, but it's still there.
