* Compiling the Factor VM * Compiling the Factor VM
The Factor runtime is written in GNU C++, and is built with GNU make and
gcc.
Factor supports various platforms. For an up-to-date list, see Factor supports various platforms. For an up-to-date list, see
<http://factorcode.org>. <http://factorcode.org>.
Factor requires gcc 3.4 or later. The Factor VM is written in C++ and uses the GNU and TR1 extensions.
As a result, it requires GCC 4.x to compile.
On x86, Factor /will not/ build using gcc 3.3 or earlier.
If you are using gcc 4.3, you might get an unusable Factor binary unless
you add 'SITE_CFLAGS=-fno-forward-propagate' to the command-line
arguments for make.
Run 'make' ('gmake' on *BSD) with no parameters to build the Factor VM. Run 'make' ('gmake' on *BSD) with no parameters to build the Factor VM.
