r - Using boost multiprecision with Rcpp on Windows -


i'm trying compile , use following code (which have seen on so):

// [[rcpp::depends(bh)]] #include <rcpp.h> #include <boost/multiprecision/float128.hpp>  namespace mp = boost::multiprecision;  // [[rcpp::export]] std::string mexp(double mx) {   mp::float128 x(mx);   mp::float128 res = mp::exp(x);   return res.convert_to<std::string>(); }

before compiling, have sys.setenv("pkg_libs" = "-lquadmath") otherwise compilation not work. compilation runs fine, when type mexp(1) in r, r session totally crashes. missing ? session crashes in rstudio in classical r gui.

ps: under windows , crash r-3.3.3 r-3.4.1.

edit:

just tried on linux r-3.4.1 , works fine. don't need sys.setenv("pkg_libs" = "-lquadmath").

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
