== DETAILS
The broadcast address is a standard part of TCP/IP that is used to
send messages to everyone on the subnet. This patch updates the
logging code to do the following:
1. Derive the broadcast address from the Wii U's own IP address
and subnet mask. These can all be obtained at runtime, which
means we can...
2. Remove the PC_DEVELOPMENT_IP_ADDRESS define from Wii U's
Makefile, because compiling in an IP is no longer needed.
3. Rewrite the net_listen script to listen for broadcast packets
and print them out with timestamps.
Since it's using the broadcast address, the only requirement is
that the PC be on the same network subnet as the Wii U.
Because of the low overhead of UDP, I've made logging on by
default. This will make it a ton easier to get useful bug
reports from users.
- move non-salamander objects out of salamander scope
- move the missing libc functions to general scope
- fix salamander_main inline invocation
TESTING: Ran 'make -f Makefile.wiiu SALAMANDER=1' successfully
This does the following.
1. Fixes checking if the CXX compiler works on platforms other than windows.
2. Turns the error when the CXX compiler is missing or doesn't work into a warning.
3. Adds HAVE_CC and HAVE_CXX.
4. Only adds CC and CXX to config.mk when HAVE_CC or HAVE_CXX are true.
5. Disables Qt companion, Vulkan, CXX_BUILD and NEED_CXX_LINKER if HAVE_CXX is false.
6. Explicitly errors when the CXX compiler is broken or missing and Qt or vulkan support is enabled.
7. No longer explicitly links with the CXX compiler on windows since this should no longer be needed.
This also adds the function `check_enabled` to `qb/qb.lib.sh` which
can be used to dynamically disable any libraries that require C++
support.
