添加第三方类库造成的linker command failed with exit code 1 (use -v to see invocation)的错误调试

linker command failed with exit code 1 (use -v to see invocation) 这个错误貌似遇见并不止一次，当我想用某个第三方类库的时候(如SBJson)，我直接把类库文件copy到工程目录里面，然后一编译就出现这样错误(并不是一定会出这样错误)，开始以为是网上下载的类库本身问题，所以重新找类库或者其他方式将它添加进去，只要不出错就行，也一直没有深入了解根本问题，今天在给工程添加一个FMDB(SQLIte第三方类库)文件编译时又出现这种错误，一开始以为工程问题，但是新建工程后还是出现这个问题，经过网上查找，得到了解决办法； [cpp] view plain copy Undefined symbols for architecture i386: "_OBJC_CLASS_$_FMDatabase" , referenced from: objc- class -ref in ViewController.o ld: symbol(s) not found for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation) 在网上得到解决办法是: 在工作左边导航栏Target-->Build

问题 It may be a silly question, but It's a silly problem that I can't find a doc for it. Pygame gives me these flags for display.set.mode(): pygame.FULLSCREEN create a fullscreen display pygame.DOUBLEBUF recommended for HWSURFACE or OPENGL pygame.HWSURFACE hardware accelerated, only in FULLSCREEN pygame.OPENGL create an OpenGL renderable display pygame.RESIZABLE display window should be sizeable pygame.NOFRAME display window will have no border or controls Ok, I can enter the Fullscreen mode..

Is there a replacement for EXIT_SUCCESS and EXIT_FAILURE in Java?

由 纵然是瞬间 提交于 2019-12-09 07:55:34
问题 In a C program, I generally use EXIT_SUCCESS or EXIT_FAILURE in exit() function to improve clarity and understandability of the program. But in System.exit() I couldn't use these MACROS. I can define my own interface as public interface ReturnValues { public int EXIT_SUCCESS = 0; public int EXIT_FAILURE = 1; } Other than my own implementation, is there any other way in java to use these Macros? (like using predefined library class variables or by implementing predefined interface etc..) 回答1:

difference between System.exit(0) and System.exit(-1) [duplicate]

问题 This question already has answers here : Difference in System. exit(0) , System.exit(-1), System.exit(1 ) in Java (11 answers) Closed 4 years ago . Can any one share to me difference between System.exit(0) and System.exit(-1) it is helpful if you explain with example. 回答1: It's just the difference in terms of the exit code of the process. So if anything was going to take action based on the exit code (where 0 is typically success, and non-zero usually indicates an error) you can control what

How can I immediately close a program in C?

问题 I am writing C code, in which I am analyzing some data. I have set the program to handle only 100 data inputs. When it has more than 100 inputs, it is giving a segmentation fault. I want to create a way so that when the number of inputs is above 100 the user will be warned and the program will terminate. I know how to do it from the main function by simply return 0 , however I am multiple function calls away from main and it is difficult to do that even a return 0 in this function will keep

What int values are relevant for exit() in C?

由 泪湿孤枕 提交于 2019-12-08 18:46:56
问题 On TutorialsPoint.com, exit is passed the value 0 , while people often pass it 1 . I've even seen exit(3); What do the different values mean? 回答1: By convention, a program that exits successfully calls exit (or returns from main ) with a value of 0. Shell programs (most programs, actually) will look for this to determine if a program ran successfully or not. Any other value is considered an abnormal exit. What each of those values mean is defined by the program in question. On Unix and
