Statically and dynamically linking the same library

阅读更多关于 Statically and dynamically linking the same library

I have a program that's statically linking to a library ( libA.2.0.a ) and also dynamically links to another library ( libB.so ). libB.so also dynamically links to an older version of libA ( libA.1.0.so ). Is this configuration possible? And if so, how does the system know to use the symbols from libA.2.0.a for my program and the symbols from libA.1.0.so for libB.so ? Yes, this configuration is possible. In answer to your question as to how the system knows how to use the symbols, remember that all of the links happen at build time. After it's been built, it isn't a question of "symbols", just

Create podspec to ship static library

阅读更多关于 Create podspec to ship static library

问题 I'm trying to ship a static library via cocoapods. I was given the library without any build directions right now its a drop in to my iOS app. I don't need to build the library for each application using it, rather just download the lib files and include the headers. Is there a way to do this with a podspec file? Here's what I have thus far: Pod::Spec.new do |s| s.name = "RTMPLib Library" s.version = "1.0.0" s.summary = "RTMPLib Library" s.homepage = "https://github.com/jumper/RTMPLib.git" s

Compile PHP into Static Binary

阅读更多关于 Compile PHP into Static Binary

问题 I need to run a php script on a system with a somewhat broken PHP install. Rather than trying to workaround the issues I want to just package my code with it's own PHP binary (I can execute an executable). I want to just have a simple php binary that has all the modules I need compiled in. My general process is: ./configure --enable-static --enable-cli --disable-all This gives me a php binary with no extensions. From here I can add the extensions I need. For example to add curl and json

Unable to edit External Library Files - showing as Locked in Android Studio

阅读更多关于 Unable to edit External Library Files - showing as Locked in Android Studio

I have ran into an odd issue. I am using an external pdf viewer library for my app and the library gives full read & write access (to modify files). During testing i realised a small glitch (which can be fixed by editing one of the library .java files) however when I go to edit the file it won't let me, in Android Studio it is showing the library as locked. I have tried removing the lock from the bottom right hand corner but this won't work either. Here is the library being added to the dependencies: compile 'com.joanzapata.pdfview:android-pdfview:1.0.4@aar' I am also attaching a screen shot

问题 This works, but doesn't build static versions of boost libraries (maybe i am wrong?) bjam --toolset=gcc --prefix=C:\boost_1_49_0-mingw install Trying to issue folloving command: bjam --toolset=gcc --prefix=C:\boost_1_49_0-mingw --build-type=complete install but it doesn't work. 回答1: You should be able to use the link=static option to let you compile the library into your binary without needing the dynamic lib: sudo ./b2 link=static Check your stage directory to make sure it goes in the right

OSX: How do I convert a static library to a dynamic one?

阅读更多关于 OSX: How do I convert a static library to a dynamic one?

问题 Suppose I have a third party library called somelib.a on a Mac running Mountain Lion with Xcode 4.4 installed. I want to get a dynamic library out of it called somelib.dylib. An appropriate Linux command would be: g++ -fpic -shared -Wl,-whole-archive somelib.a -Wl,-no-whole-archive -o somelib.so where -whole-archive and -no-whole-archive are passed to the linker. When I do the equivalent for Mac: g++ -fpic -shared -Wl,-whole-archive somelib.a -Wl,-no-whole-archive -o somelib.dylib ld fails

Can a C++ Static Library link to shared library?

阅读更多关于 Can a C++ Static Library link to shared library?

问题 Say I have a static C++ lib, static.lib and I want to call some functions from a C++ shared lib, say shared.lib. Is it possible? Now assume that I have another shared lib, say shared2.lib which links to static.lib but does not link to shared.lib. Does the linker automatically link shared2.lib to shared.lib in this case? I am using Microsoft Visual Studio 2003. 回答1: Static libraries are not linked. They are just a collection of object files (*.obj or *.o) that are archived together into a

Static library dependency compiles in simulator on Xcode 3.2.3, fails on device

阅读更多关于 Static library dependency compiles in simulator on Xcode 3.2.3, fails on device

Upgrading to XCode 3.2.3 and iPhone 3.2/4.0 SDK has introduced a strange bug into my build process. I have a static library, Compton, which itself depends on three20. I build Compton as a dependency of the client apps that it powers. When I compile Compton as its own project in either simulator or device mode, 3.2 or 4.0 SDK, everything compiles fine, no errors. When I compile a client app that references Compton using the 3.2 or 4.0 SDK, simulator, targeting the iPhone or iPhone / iPad on 3.2, everything works great, no compile errors, and the app runs as expected in the simulator. When I

IOS Static Library Product is always red

阅读更多关于 IOS Static Library Product is always red

问题 I've been struggling with this for a few days now. When I create a new Static Library project under IOS in XCode 4 I am running into an issue. With or without adding files as headers or to be compiled I am able to successfully build but the .a file is always red. This happens in both Debug and Release. I've read about similar issues but haven't found someone who has fixed the problem. Any help would be appreciated. Thanks 回答1: XCode seems to have a bug in this regard when building for the

Using Objective-C code in iOS Cocoa Static Library project with Swift code in iOS Application project

I am looking for a simple procedure for combining an Objective-C code from a shared library project with Swift code from an application project but have had no success so far with this sequence: start Xcode 6.1.1 create workspace Test create iOS Cocoa Touch Static Library project TestLibrary and add it to workspace create iOS Single View Application project Test (language: Swift) and add it to workspace add import TestLibrary to ViewController.swift If I now build Test, I receive this error in ViewController.swift: No such module: ‘TestLibrary’ . Presumably two hurdles must be overcome: Tell
