Compile problem on Mac OS with clang 10

[sebjameswml]

This problem has been experienced by @benoit-girard with this cmake call:

cmake -DSTANDALONE_INSTALL=ON -DCOMPILE_WITH_X11=OFF \ -DLICENCE_INSTALL=OFF -DCMAKE_INSTALL_PREFIX=/Users/yourname ..

"make -j4" returned:

I think this may be bit-rot, with some tweaks required on a Mac:

This is complaining that in the call to bind() at line 85 of brahms/framework/channel/sockets/sockets.cpp it can't compare a thing called

__bind<int &, const sockaddr *, unsigned long>

with an int.

The line of code is:

if ( bind( serverListenSocket, (OS_SOCKADDR*) &con, sizeof(con) ) == OS_SOCKET_ERROR)

Now, on Linux, the call to bind() returns an int, and that can be compared with OS_SOCKET_ERROR which is a numerical definition and is interpreted as an int.

It seems that on a Mac with clang10, the call to bind is returning some sort of special __bind object, so there seems to be some bit-rot in this bit of brahms. It looks like the bind system call is being implemented in a c++ way. A check on the Apple developer website suggests that you can still use the unix/C style sockets interface and the bind(2) function call, and that it should, as is typical, return an int. There's probably some Mac-specific tweak required, or a slight change to a #include to get this to compile, but I'm afraid I don't know what it is, and I don't have access to a Mac at the moment.

Sorry I can't be more help! I'll open an issue.

@ajc158 have you got a Mac? Does brahms build on it?
