compilation

问题 In one of the very big projects I used auto-synthesized properties everywhere: //MyClass.h file: @interface MyClass : NSObject @property (nonatomic, retain) NSString *deviceName; @property (nonatomic, retain) NSString *deviceID; @end //MyClass.m file: #import "MyClass.h" @implementation ApplicationStatus // no @synthesize used at all. -(void)dealloc{ [_deviceName release]; // gives errors only while converting to ARC with LLVM 5.0 [_deviceID release]; [super dealloc]; } @end The code above

问题 I am trying to compile a basic program that i can get to cross compile on my mac. I am running Mac OS X Mavericks. My cross compiler is arm-elf-gcc-4.7.3. I wrote a simple test program that looks like: int main() { ; return 0; } When I run /opt/local/bin/arm-elf-gcc-4.7.3 -o test test.c I receive these errors. test.c:4:Unknown pseudo-op: .global test.c:4:Rest of line ignored. 1st junk character valued 109 (m). test.c:5:Unknown pseudo-op: .type test.c:5:Rest of line ignored. 1st junk character

问题 I have been working on some GUI-related projects in Eclipse CDT. They always require me a specific command line pattern (Project > GCC C Linker) in order to load the libraries properly: I can't manage to keep that configuration for every project I start. Is there a way to achieve this? 回答1: IMHO it is not possible. See in Windows > Preferences > C/C++ Build > Setttings these options were not provided. So all these options are specific to a project. Means you can have different options for
