Hi Everyone, We added two new functions to the library. They are HeaderVersion and LibraryVersion. HeaderVersion is CRYPTOPP_VERSION from cryptlib.h, and its an inline function that always reports the version as recorded in the header. LibraryVersion is also CRYPTOPP_VERSION, but its recorded in the static archive or dynamic library at library compile time. It does not change if the wrong headers are used.
The functions dropped out of another project's bug report where they believed they were using a particular version of the library, but headers/libraries were being mixed and matched. In an ideal world, build systems and users always pick the right version of the library. Inthe real world things sometimes go astray. The functions use C linkage, so they can be located without name mangling. If you dlopen/dlsym the library and the symbol is not present, then you are using 5.6.5 or below. If the symbol is present, then its 5.7 or above. The downside is they are 10-based, so you have to do things like (HeaderVersion() / 10) % 10 to get the minor version number. The workaround was to add additional symbols, and I kind of wanted to avoid it. They were committed at https://github.com/weidai11/cryptopp/commit/6f7339c81b26985a830da6efe1da59e3897f6b71 and https://github.com/weidai11/cryptopp/commit/42af35fd2bcf00e983772dbb6e409f8ba5f49fc6.
