Re: How to make c++ realize empty character constant ''?
If you're trying to make a C/C++ string, perhaps you want '\0'. But I can't tell what language you are working with or what exactly you are trying to accomplish.

Re: How to make c++ realize empty character constant ''?
It seems to me you are trying to assign a character value to a string. A character is a single 8-bit (or 9 or 10 or 16 or 32 ...) value. A string is a series of characters, terminated or not. Assuming you have the proper classes, you overloaded what needs to be, at best your assignment should look like frac_str = ; J.

Using gcc/gfortran 4.8 in MacPorts
Hi all, Please forgive-me the ignorance if this seems to simple a question. I installed gcc4.8 from MacPorts, and now I want to use its compilers, especially gfortran. However, although they are in the path, their names are different, such as gfortran-mp-4.8, such as they are not seen when the command gfortran is issued. I tried to see what is working and got: $ port select --list gcc Available versions for gcc: mp-gcc48 none (active) however, for gfortran: $ port select --list gfortran Warning: Unable to get active selected version: The specified group 'gfortran' does not exist. Error: The 'list' command failed: The specified group 'gfortran' does not exist. I tried to activate the MacPorts gcc set by: $ sudo port select --set gcc mp-gcc48 Password: Selecting 'mp-gcc48' for 'gcc' succeeded. 'mp-gcc48' is now active. And now the correct gcc is working: $ which gcc /opt/local/bin/gcc however, still nothing is set for gfortran: $ which gfotran $ (returns nothing) So, my question is this: how should I activate the whole gcc48 set? Especially, I need to use gcc/gfortran. BTW, shouldn't this be activated by default when I install gcc48?

This warning can be suppressed (add parameters: -Wno-invalid-pp-token -Wno-unicode -Wno-trigraphs) but very little can be done if clang's cpp is producing output you don't expect.

We can't tell for certain without knowing what your environment looks like, but it is very likely that your replacement libraries are shadowing some standard function in a way that breaks MacPorts (and may affect other OS X native software although perhaps not as drastically).

Re: How to make c++ realize empty character constant ''?
Hi Chris Yes, it is fortran code. I am not sure why it uses CPP to compile it. From the compilation statement, Fortran code is converted to .b file and then to compile it. I am not sure why.

Re: fife Unknown Horizons Game
I was able to compile fifengine from git by following these instructions: http://wiki.unknown-horizons.org/w/MacOS_build_notes Once fife is compiled, the Unknown Horizons game is actually just written in python, so it should be easy to make a port for it. Apparently they are trying to move away from using the libguichan (currently provided by a port) to some other system that isn't available in macports. But for now it works with only minor problems.
