Exceptions or STL classes shouldn't cross library boundaries though, otherwise things will break.

- gpderetta 10y agoIt will work perfectly fine as long as the libraries use compatible ABIs. Make sure that your compiler provides a stable std library ABI.
- blub 10y agoGood point that it's technically doable. Is this done a lot in practice? I had the impression that a lot of projects stick to C APIs in dynamic libraries.
- gpderetta 10y agoMSVC does not guarantee a stable standard library ABI, so those that need to target it are out of luck. In linux land, the switch from libstdc++5 to 6 still haunt the memories of many, although it was quite a long time ago (gcc 3.4) and the ABI has been stable since. In practice the reason that many projects provide a C ABI is that they want to interoperate with other languages and the C ABI, being extremely minimalist, is the least common denominator.
