static-libraries

I was following this tutorial and stumbled across this screen shot: apparently there was a way to make the Xcode project file relative to some user defined env variable in earlier versions of Xcode (you get there by highlighting the project file then clicking cmd + i ) I couldn't find a way to this in Xcode 4.5 (the closest I could get to that was this post, but the instructions don't work on Xcode 4.5) ideas? update : I tried the idea of changing the 'header search paths' under build settings.. and setting 'always search user paths' to 'yes' as suggested here .. but then my project always

I'm trying to write a program to use a static library of a C++ code into another C++ code. The first C++ code is hello.cpp : #include <iostream> #include <string.h> using namespace std; extern "C" void say_hello(const char* name) { cout << "Hello " << name << "!\n"; } int main(){ return 0; } The I made a static library from this code, hello.a , using this command: g++ -o hello.a -static -fPIC hello.cpp -ldl Here's the second C++ code to use the library, say_hello.cpp : #include <iostream> #include <string> #include <dlfcn.h> using namespace std; int main(){ void* handle = dlopen("./hello.a",

I am building a static library and am receiving no compiling errors, however, when I link it against a demo project(basic single view app). I cannot step into the methods called from the static library to debug it... I'm not receiving any runtime errors, but I think that is because it's not being executed due to the fact my NSLogs are not being shown, and it's not returning anything... Basically, how do I debug a static library I created through the demo app I also created.. What do I do? I need help!! Thanks in advance... To use runtime debugger you should add your static library project as

OK, I'm trying to create a Cocoa Library (static) and use, but I keep getting errors. I created a super-basic static Library ( TSXLib ) with just one additional class in it. #import <Foundation/Foundation.h> @interface ClassOne : NSObject - (void)doIt; @end #import "ClassOne.h" @implementation ClassOne - (void)doIt { NSLog(@"Oops... I did it again!"); } @end Then, I set the Dynamic Library Install Name (in Build Settings) to : @executable_path/../Frameworks/libTSXLib.a Now in my Test Project : I drag'n'drop the libTSXLib.a file (and copied it to target) Added a Build Phase (Copy Files) where I

Problem: The firmware image generated when linking with a static library is different to the firmware image generated when linking with the objects directly extracted from the static library. Both firmware images link without error and load successfully onto the microcontroller. The latter binary (linked with objects) executes successfully and as expected, while the former (linked to the static library) does not. The only warnings during compilation are unused-but-set-variable in the manufacturer-supplied HAL, which due to various macro definitions are not necessary for the compiled

Following the answer given to this question (Developing C wrapper API for Object-Oriented C++ code) I managed to write a C wrapper for my C++ code. I would like to compile and link my wrapper into a static library (compiled using g++) that could be used, compiled and linked using gcc only (not g++). This way the user of the library would not have to care that the library is written in C++. Is this something possible?
