问题 widgetCategory was added in Android 4.2 SDK level 17. I decompiled an APK with apktool, added the widgetCategory attribute to a xml file, and recompiled. The error is this: No resource identifier found for attribute 'widgetCategory' in package 'android' I have tried using the latest aapt and changing the sdk level in apktool.yml but neither solved the problem. Is there anything I need to change to add support for Android 4.2 to apktool? 回答1: Set build target to API 17. In Eclipse you can

问题 I'm trying to write a (desperately tiny, simple — I have no idea what I'm doing, let's be real!) compiler in OCaml. I'd really like to avoid checking any ISO-C code into the project (despite knowing C fairly well; the goal here is to learn and use OCaml exclusively.) Pursuant to this, I need to write a “runtime” for the compiled language in OCaml, compile it separately from the primary project, and then link it against the compiler-itself's output. Unfortunately, it looks like any external

问题 I haven't tried it yet, but I know you can supposedly run AWS Lambda functions in Java and reference C++ libraries from them. How do you compile the C++? 回答1: I was struggling to do exactly what you ask only a few days ago when I've stumbled upon this article: http://www.glfrc.com/2018/01/19/aws-lambda-with-java-and-native-code/ You basically have 2 options: on an Amazon Linux EC2 machine. on any machine running docker by using the Amazon Linux docker image. The article explains the second

问题 I am new to the Mac OS X environment when it comes to compiling linux based libraries. Whenever I used a library i just downloaded the .framework file, added it to my /Library/Frameworks and included it in my XCODE project, and all was fine. Now I am stuck with libnoise. I want to use it on my project and I have no idea how to generate the .framework file/directory. Can you help me please? 回答1: If you have libnoise, most likely it contains some sort of a Makefile or a configure script. By

问题 In Java, with Sun's JDK 1.6, with an enum such as this: public enum MyEnum { FIRST_MEMBER { public void foo() { } }, SECOND_MEMBER { public void foo() { } }, THIRD_MEMBER { public void foo() { } }; } The compiled files are: MyEnum$1.class MyEnum$2.class MyEnum$3.class MyEnum.class This also means that a stack trace showing foo() , or the method call printed in JVisualVM, etc., will have something like this at the top: mypackage.MyEnum$1.run() The $1 in the class name is due to the members of

问题 I'm intrigued by the idea of using Xgrid to speed up my Xcode compiling across multiple machines... but it seems very difficult to find any information on people's experiences with it, any gotchas, etc. I don't have multiple Macs that I can test it with right now, so I'm curious. Have you tried it? How well has it worked for you? What kind of speedups have you seen? 回答1: I used it for a while, but generally didn't get very good results for moderate sized projects (things that take less than 5

问题 I have run into a compile-time error I do not understand while working with F# in Visual Studio 2012. I could find a minimal snippet here: http://ideone.com/hbhbF type Foo() = inherit System.Exception() member inline this.Bar() = () Foo().Bar() What do the following error messages mean? /home/iU0RLi/prog.fs(3,22): error FS0073: internal error: the mustinline value 'Bar' was not inferred to have a known value /home/iU0RLi/prog.fs(5,1): error FS1114: The value 'Prog.Foo.Bar' was marked inline

问题 I want to compile a Python 3.3 module with submodules using cx_freeze. So, my dir strucuture is: projectname/ __init__.py submodule1/ __init__.py bootstrap.py script1.py submodule11/ script2.py submodule2/ ... In the __init__.py I import from submodule1 import bootstrap and from the bootstrap import submodule1.submodule11.script2 If I run the init file, anything is good and the script with the submodule imports is executed correctly. When I compile it, I use this setup.py: from cx_Freeze

问题 I have a problem in my code. In Xcode or using the C++11 compiler, this code works well. However, when I am submitting this code to an Online Judge, the verdict shows "Compile Error" . I think they use the C++4.7.1 compiler, which when I tried to compile it (using Ideone), it says: prog.cpp: In function 'void printArray(int)': prog.cpp:27: error: 'void*' is not a pointer-to-object type prog.cpp:27: error: 'void*' is not a pointer-to-object type prog.cpp:27: error: 'void*' is not a pointer-to

问题 Is there a way to enable thread safety in PHP without recompiling, or to use YUM to do this? I am trying to install pthreads and it requires PHP to have been compiled with --enable-maintainer-zts . However, I do not with to recompile because I would like to manage my PHP stack using yum. I am currently using the REMI repo. I notice there is a package php-zts, however, there is not one available for my PHP version of 4.4 and I cannot find a source RPM for php-zts. Is there a way I can use yum
