I'm not sure what you mean here: do you mean that code which works with Boost.Regex fails with another/commercial implementation of the TR1 regex library? If so you'll have to contact the vendor I'm afraid, or else use Boost.Regex instead ;-)

HTH, John.

Hi,

no, that's not what I wanted to say. I'm using the Boost.Regex library inside another application which has a C/C++ API.
