(if the project uses C++, you might also need to sed `CXX=i686-w64-mingw32-g++`)
## building double-precision externals
At the time of writing (2018-02) there is no official Pd that supports
double-precision numbers yet.
However, if you do get hold of an experimental double-precision Pd, you can
easily build your externals for 64-bit numbers:
make CPPFLAGS="-DPD_FLOATSIZE=64"
## building externals for W64 (64-bit Windows)
At the time of writing (2018-02) there is no official Pd that supports
W64 yet.
However, if you do get hold of an experimental W64 Pd, you can
easily build your externals for this environment with
make CPPFLAGS="-DPD_LONGINTTYPE=__int64" CC=x86_64-w64-mingw32-gcc
To build a double-precision external for W64, use something like:
make CPPFLAGS="-DPD_LONGINTTYPE=__int64 -DPD_FLOATSIZE=64" CC=x86_64-w64-mingw32-gcc
