Hi there, I am using a multitude of different Boost libraries in my code. Since that code is growing quickly, I am increasingly running into bugs which I (sometimes) consider to be on Boost's side. Allowing only selected Boost versions which are known to run fine with my code would allow me to keep that code simpler and thus less error-prone. As my main platform is Linux, however, which usually comes with a given version of Boost (currently often 1.39), my users would be forced to compile Boost themselves, which will mean that they are less likely to start using my code. If I generally allow all Boost versions above a given version, I have to work around known bugs in certain Boost versions, at the expense of code simplicity and thus stability. However, it will be easier for users to adopt my code. Which strategy did you pick for your code ? Kind Regards / Mit freundlichen Gruessen, Ruediger Berlich
