I am able to build my Python Extension Module under MSVC 7.1, MSVC 8.0 and GCC (LINUX). However I cannot seem to build it under Cygwin gcc. The output of uname is CYGWIN_NT-5.1 The output of gcc -v is : Reading specs from /usr/lib/gcc/i686-pc-cygwin/3.4.4/specs Configured with: /gcc/gcc-3.4.4/gcc-3.4.4-1/configure --verbose --prefix=/usr

David, Thanks for the answer. I am just curious: Does boost-consulting sell the CDs to make money, or to make it easier for the users where all libs are available at once precompiled for different compiler versions etc.? I see one major drawback with selling of CDs: If someone needs boost libs (most probably at work) then they are needed "right now!". Therefore there is no time to wait until it ships. How much time would it take to send a CD to Germany? (my case) I think at least one week :( I cannot wait one week for the CD if I need my project to be done. If you would offer a complete ISO image or alternatively ZIP for download for USD 5,- I would pay for it... It is also possible that you make some kind of an update service where people are notified, that a new ISO with most recent boost libs is ready. You can also provide a subscription and some kind of priority support (for one year or 6 months) for USD 100,- (or more, might depend on support level or support plan), where people can ask boost consulting for advice, patial concept review, etc. I mean virtual consulting services in the style of: Ask boost professionals to identify application flaws at a flat rate. I don't kwow if the suggested scenario works, but for some Linux companies this was working well (for some other not).

Hello,

is there any way to specify the proxy server to the installer provided by boost-consulting? At work I can access inet via some proxy server only.

Not yet.

Now I have to rebuild the entire boost lib again...

May be boost-consulting should offer big old monolithic single file installations for vc8.0 or vc7.1 for those who cannot easily access network and still require all libs.

We're selling installer DVDs (not cheap yet, though, since we're not mass producing them). -- Dave Abrahams Boost Consulting www.boost-consulting.com
