That's probably due to the compiler branding (or lack thereof). I'm guessing its the standard GCC label (and not something clever like "Vincent's GCC 7.2"). I think we have two options. First, we require users with non-branded compilers to manually add the options. This is what you have to do at the moment. Second, we pick a GCC version, like GCC5, and then unconditionally apply the options. Several years ago Uri advised us to take this option. I declined it at the time because we did not have the uses cases. Now that we have use cases and are seeing how things are breaking, I think we can cast a wider net. The question is, should we do nothing (option 1) or add the options (option 2)? Jeff -- -- You received this message because you are subscribed to the "Crypto++ Users" Google Group.
