# MAKEFILE for linux GCC
#
# This makefile produces a shared object.
#
# Thanks to Zed Shaw for helping debug this on BSD/OSX.
# Tom St Denis
#
#  (GNU make only)

### USAGE:
#
# CFLAGS="-DUSE_LTM -DLTM_DESC -I/path/to/libtommath" make -f makefile.shared all EXTRALIBS=/path/to/libtommath/libtommath.a
# ./test
# make -f makefile.shared PREFIX=/opt/libtom install
#

PLATFORM := $(shell uname | sed -e 's/_.*//')
### Observed uname outputs:
# MINGW32_NT-6.2          (on MSYS/MINGW old)
# MINGW64_NT-10.0-14393   (on MSYS new)
# MSYS_NT-10.0-19042      (on MSYS2)
# CYGWIN_NT-10.0          (on Cygwin 64bit)
# CYGWIN_NT-6.2-WOW64     (on Cygwin 32bit)
# Linux                   (on all Linux distros)
# Darwin                  (on macOS, OS X)
