| # This Makefile fragment sets the following make variables according to the |
| # current platform: |
| # ARCH - the Mozilla architecture name, such as x86, x86_64, ppc, etc |
| # FLAG32BIT - 32 or 64 |
| # MARCH - the Mac architecture, such as i386 or ppc |
| # OS - linux, mac, or sun |
| # CFLAGS - appropriate C compiler flags for this platform |
| # CXXFLAGS - appropriate C++ compiler flags for this platform |
| # Also, various stanard make variables are overridden if necessary, such as AR |
| # |
| # If ARCH is already set, that is used instead of uname -m to get the |
| # architecture to build. This can be used to build a 32-bit plugin on a 64-bit |
| # platform, for example: make ARCH=x86 |
| |
| ARCH ?= $(shell uname -m) |
| |
| # default is 32 bits |
| FLAG32BIT=32 |

| # Figure out 64-bit platforms, canonicalize ARCH and MARCH |
