Re: bjam and windows command line problem.

OK. But, now, do I need to run libs/config/configure to configure for gcc-nocygwin? Would I need to set any environment variables or command options to do that?

Thanks

I looked at the website. The only mention of building bjam for gcc-nocygwin is with using build.bat.

You don't need to rebuild bjam for each toolset you want to use it with; you only need a new version for each *platform* you want to use it with [Rene, people keep making this mistake; would you mind updating the documentation to make this clear? -- thanks!]. Any compiler that works on that platform will do.

On windows, the Windows command-line and the Cygwin shell are essentially two separate platforms. Note that gcc-nocygwin doesn't appear in the list of supported toolsets for building bjam under Cygwin, only for building bjam under Windows.

So, I ran (from a cygwin command line)

build.bat gcc-nocygwin

and, it failed while trying to build fileunix.o, as follows:

Maybe I answered my own question. I set CXXFLAGS to -mno-cygwin and ran configure. The user.hpp file it generated allowed me to build the threads for the first time. --- In Boost-Users@yahoogroups.com, "silvermangbs" wrote: pathvms.c

Is there some other way to build bjam for gcc-nocygwin?

You don't build bjam *for* a toolset; you build it for a platform *with* a toolset. If you want to build from Cygwin (with any supported toolset), you can just use the gcc toolset to build bjam. And don't use build.bat unless you want a Windows-hosted bjam. If you really want to build from Cygwin, use build.sh.
