I ported lophttpd to OSX/Darwin (10.8 tested).
As OSX/Darwin is almost POSIX-compliant (live_free() || die())
and I already separated the low-level stuff to the -flavor
files, this was not overly complicated.
Now it pays that I chose to do it that way, rather than
having a dozen of #ifdef stacked around.
lophttpd now cleanly builds on BSD (untested for some time),
Linux, Android and OSX/Darwin.
What nerves most is the various integer-size issues you
have with size_t, off_t, suseconds_t etc. and the corresponding
format specifiers with the *printf() family. However you do it,
one OS shouts at you for passing wrong sized parameters to
*printf(). Despite of any standards. Live free or die.
You can easily build it on OSX/Darwin by installing Xcode
and then installing its command-line tools. Thats not
gcc AFAIS, but it should also build if you manage to install
gcc toolchain there.
I had to disable warnings about deprecated use of OpenSSL
in OSX and I have hard times not commenting on that in light
Live free and die. :)
