Installing fftw-2.1.5 with openMPI -


trying install fftw use gadget2, , after running following command:

./configure --enable-mpi --enable-type-prefix --enable-float

i message:

checking mpicc... mpicc checking mpi_init... no checking mpi_init in -lmpi... no checking mpi_init in -lmpich... no configure: error: couldn't find mpi library --enable-mpi

now have installed openmpi already, seems case can't find it. there similar question posted while ago different mpi software. think problem openmpi , other compilers might in different folders? brings me more general question (i have tried googling can't find explains well):

if extract tar , use ./configure without prefix, program install to? , issue openmpi has reason installed different place?

thanks!

edit: found solution this question, running

sudo ldconfig

seemed fix , compiles fine.

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
