c++ - Qt deployment error on linux -


i tried deploy test qt program on ubuntu following http://doc.qt.io/qt-5/linux-deployment.html. when run program on ubuntu machine (without qt). keep give error: segmentation fault (core dumped). tried both staticly , dynamicly complied, give me error. test code simple , show small window.

#include<iostream> #include<qapplication> #include<qmainwindow> using namespace std; int main(int argc, char** argv){   qapplication app(argc,argv);   qmainwindow *win=new qmainwindow();   win->show();   return app.exec(); }

the .pro file

template = app target = test qt += widgets includepath += . # input sources += main.cpp

after static qmake complie comand:

$/usr/local/qt5.8.0/5.8/src/qtbase/bin/qmake -config release $make

i got test program.

i tried copy related library shell script:

#!/bin/sh   exe="test"   des="."   deplist=$(ldd $exe | awk  '{if (match($3,"/")){ printf("%s "),$3 } }')   cp $deplist $des

and got many related library files like: libc.so.6 libfontconfig.so.1 libicudata.so.55 libnvidia-tls.so.340.102 libstdc++.so.6 libxau.so.6 libxcb-sync.so.1 , on.

then set run-program script test.sh

#!/bin/sh appname=`basename $0 | sed s,\.sh$,,` dirname=`dirname $0` tmp="${dirname#?}" if [ "${dirname%$tmp}" != "/" ]; dirname=$pwd/$dirname fi ld_library_path=$dirname export ld_library_path $dirname/$appname "$@"

when running script test.sh, successful on ubuntu qt machine. when copy script , library files , run on no qt ubuntu machine, give me "segmentation fault"

i dont know causes problem. is library files libc.so.6 or other steps missed. appreciate help.

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...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
