Atlas of Lie Groups and Representations | |
|
To compile atlas on the Mac you must install a C compiler. The standard one is the one contained in the XCode package. Note: Even though the XCode C Compiler is called gcc, it is really (starting with XCode 4) a symlink to llvm-gcc, which has some some bugs. See XCode 4 ships a buggy compiler. In any event llvm-gcc is not well suited to compiling the atlas software; it appears to be impossible to compile with optimization enabled. For this reason we recommend the true gcc compiler provided by MacPorts. Due to a chicken and egg problem, you must first install the XCode Compiler, in order to install Macports, and then gcc. Back to compiling on the Mac. | ||
