universal-binary

问题 I'm trying to compile a Boost library into a universal binary file (i.e. a "fat" file that contains builds for both the i386 and x86_64 architectures). Souring the internet and SO I assembled the following instructions. Download boost (e.g. from http://www.boost.org/users/download/) In the downloaded folder, type ./bootstrap.sh (or, in my case ./bootstrap.sh --with-libraries=thread , since I only need the thread library) type ./b2 install cxxflags="-arch i386 -arch x86" These steps installed

问题 I don't know how to convert a non terminating binary number(fraction) to decimal . Can anybody guide me how to do with an example? 回答1: if the binary number is a unterminated integer, it would be infinite (positive or negative). How can you represent infinite number in decimal? I think it's ∞ . else if the binary number is a float-point number, congratulations. In many standard of float-point number(e.g., IEEE 754), the mantissa is represented by a binary pattern in which the highest bit has

问题 I created an app that was rejected because Apple say that my App was not showing the correct iPad window and it was showing the same iPhone screen but top left aligned. Running on simulator, I get my App to show exactly what it should, a big iPad View. my app as Apple referees that is showing on device: alt text http://www.balexandre.com/temp/2010-04-22_0939.png my app running the simulator (50% zoom only): alt text http://cl.ly/cCH/Screen_shot_2010-04-22_at_09.40.24.png my code in the

问题 I am trying to build a Universal binary on MacOSX with g++. However, it doesn't really work. I have tried with this simple dummy code: #include <iostream> using namespace std; int main() { cout << "Hello" << endl; } This works fine: % g++ test.cpp -arch i386 -arch ppc -arch x86_64 -o test % file test test: Mach-O universal binary with 3 architectures test (for architecture i386): Mach-O executable i386 test (for architecture ppc7400): Mach-O executable ppc test (for architecture x86_64): Mach

问题 how can I set up a Universal project which has support for iAd (just in the iPhone app)? Using the iPhone SDK 4, let's suppose I do the following steps: Open XCode; Go to File > New Project ; Select Window-based application (or whatever), choose Product: Universal (and after choose a name for the project). It will create a Universal project skeleton with iPhone/iPad groups as usual. Now, I decide to integrate iAd in my iPhone App, so I do the following: Right-click in the project's group

问题 I have an Xcode project that has a "master" static library target, that includes/links to a bunch of other static libraries from other Xcode projects. When building the master library target for "Optimized (armv6 armv7)", an error occurs in the last phase, during the CreateUniversalBinary step. For each .o file of the libraries that is included by the master library, the following error is reported (for example, the FBConnectGlobal.o file): warning for architecture: armv6 same member name

问题 Does anyone (here) know if Windows 8 will have a sort of fat exe that one can compile with Visual Studio 2012 that will be supported on both ARM and x86 machines? I am guessing not, since you can't create fat binaries that will execute 32 or 64 bit code so far as I am aware (only solution available that I am aware of is 32 bit that creates a 64 bit executable on the fly). It seems like it would be helpful of Microsoft to extend exe or create a fat binary format for Windows 8 and beyond at

问题 I have an iPhone app that I have started to turn into a universal app, however the process is not complete and I want to release an update to the iPhone version. I know that you can specify device capabilities in the Info.plist file to restrict your app to certain devices, but how can I do this to prevent the unfinished universal version from appearing in the iPad store? Is checking the LSRequiresiPhoneOS BOOL entry (in the Info.plist file) enough? Thanks! 回答1: You could use the
