building for 64-bit Pd on Windows

[ahihi]

hi,

i'm trying to build flext for 64-bit Pd (amd64, not double precision) on Windows 10 using MSVC. since MSVC doesn't allow inline assembly on 64-bit, this fails on flsimd.cpp and (with SIMD disabled) lockfree/cas.hpp.

is it possible to do a 64-bit build? should i be using MinGW or Cygwin instead of MSVC?

[grrrr]

I would definitely recommend Gnu C instead of MSVC. Nevertheless it should be possible to exclude the problematic sections by some preprocessor code. Sorry, can't look into it at the moment.

[ahihi]

no worries and thanks for the fast reply!

out of MinGW and Cygwin, would you recommend one over the other? would i also need to build Pd using the same compiler?

[ahihi]

i couldn't figure out how to solve this using the preprocessor, so i set up MinGW-w64 and was able to build flext (with a small change).

my problem now is building py (python 2.7 version from your master branch). with a few more changes, i can run

..\flext\build.bat pd mingw build-default-multi

and compile all the source files, but linking fails:

(i know i have extra quotes in -L""C:/Python27"/libs", but it shouldn't make a difference here)

the incompatibility seems to be because for some reason, even 64-bit Pd ships 32-bit versions of these libraries. i'm not sure what to do here, since i can't seem to find direct equivalents from the MinGW repos either.

i also don't understand why apparently MSVC-related libraries are involved when building with MinGW, so i tried using -lpthread instead of -lpthreadVC. this gives me the same -lmsvcrt incompatibility messages and a whole lot of undefined references...
