the default GCC 4.4.6, compile and install GCC 4.7.2.
On the Internet to upgrade the compilation of GCC tutorials a lot of steps are very cumbersome, painful process I do not say, I only say a little, in fact, things can be very simple.
The first is dependent on the library, the official document said the need for GMP, MPC, MPFR, and provide a download address, many tutorials have said their own compile in
1. There is currently no support for Java8 compile in eclipse (my version of Kepler).
The figure adds jdk8,jdk7,jdk6 to eclipse, but at compile level there are only:
No 1.8 appeared. As you can see, compile uses a built-in compiler and does not use the Javac in JDK.
2. The solution. Http://stackoverflow.com/questions/8122843/how-to-have-eclipse-use-jdk8-to-
This article describes the Linux platform compiler installation PHP7 and installation of Redis extension and swoole extension methods. Share to everyone for your reference, specific as follows:
The previous PHP7 installation Redis extended Tutorial Linux and Windows platform tells readers how to install Redis in a simple way, let's implement a method of compiling and installing PHP7 in Linux and installing Redis extensions and Swoole extensions.
Compile
Class and Object oriented:
Display interface (explicit interface): that is, visible in the source code, you can see all the interfaces of the class in the header file;
Run-time polymorphism (Runtime polymorphism): A member function is virtual, when a reference or pointer to a class is passed, the interface is automatically matched at run time, possibly the interface of a base class, or a derived class;
Template (templates) and generic programming (generic programming):
Implicit interface (im
Invalid r class path shown in problem 1:mainactivity.java
Workaround: As does not automatically generate R files for some reason. For example, if the project relies on a library file version that does not match the specified compilesdkversion, you need to manually specify the version number of the library file that needs to be compiled. For example, Android.compilesdkversion is 19, then add at the end of Project->app->build.gradle

Preface
Memcached is a high-performance distributed memory object caching system for dynamic Web applications to mitigate database load. It improves the speed of dynamic, database-driven Web sites by caching data and objects in memory to reduce the number of times a database is read.Memcached is based on a hashmap that stores key/value pairs. Its daemon (daemon) is written in C, but the client can write in any language and communicate with the daemon through the memcached protocol.Of cours

An explanation of the extern "C" usage in C + +extern "C" indicates a compilation protocol in which extern is the keyword attribute and "C" characterizes the compiler link specification. For the extern "C" can be understood as a mixed programming in the C++/C of the compilation instructions. Use "C" to compile and link in C + +.extern "C" contains a double meaning, literally: First, the object it modifies is "extern", and secondly, the target it modif
