The problem is that TRY_COMPILE doesn't catch missing functions. Missing functions are found at link time. (I actually tried it with COMPILE before I had my "oh duh" moment). It's an odd case, because it's actually a macro that wraps around an existing function. It's functionally this: #define foo(x,y) bar(new_enum_value, x,y) Where bar already exists in older code but the foo and new_enum_value remap only exists in newer versions. >> + [#include <openssl/bio.h>], >> + [BIO_dgram_get_peer(NULL, NULL);],, >> + AC_MSG_ERROR([DTLS support requires a newer version of OpenSSL])) MF> I would prefer if this error showed up somewhere close to the transport MF> search code and not down here but if could be moved later. I was trying to stick with existing convention of testing functions in the function checking space. I actually *wanted* to write it up previously. [I also want a better error message with the minimum version number, but I don't know it off the top of my head and haven't gone to go look through all the openssl versions to find where it was introduced. Probably near 0.9.8m.
