Hi Roie, I also compiled stunnel 5.70 using mingw and I see the same issue. You can get rid of the warning by replacing %llu by %I64u in the code. Most likely, this issue does not show up in the official binaries that are compiled using the Microsoft compiler.

Hi,

Trying to build stunnel the following warning showed up:

network.c: In function 's_read': network.c:737:44: warning: unknown conversion type character 'l' in format [-Wformat=]         s_log(LOG_ERR, "s_read: Received %llu out of requested %llu byte(s)",                                             ^ network.c:737:66: warning: unknown conversion type character 'l' in format [-Wformat=]         s_log(LOG_ERR, "s_read: Received %llu out of requested %llu byte(s)",                                                                   ^ network.c:737:24: warning: too many arguments for format [-Wformat-extra-args]         s_log(LOG_ERR, "s_read: Received %llu out of requested %llu byte(s)",                         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

And one more of the same kind. I wonder how it didn't happen in the official binaries. Are they being built using the instructions in INSTALL.W32 ? Using xmingw-64 ?
