在Yosemite上的Eclipse中调试C程序时出现问题

Question

I am getting the following persistent errors trying to debug a C program in Eclipse Juno on my mac:

Building target: TimeStamps Invoking: MacOS XC Linker gcc -v -o "TimeStamps" ./graphic/arrow.o ./graphic/axesdraw.o . . . Apple LLVM version 6.0 (clang-600.0.57) (based on LLVM 3.5svn) Target: x86_64-apple-darwin14.1.0 Thread model: posix "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ld" -demangle -dynamic -arch x86_64 -macosx_version_min 10.10.0 -o Undefined symbols for architecture x86_64: "_main", referenced from: implicit entry/start for main executable ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) make: *** [TimeStamps] Error 1 Building target: TimeStamps Invoking: MacOS XC Linker gcc -v -o "TimeStamps" ./graphic/arrow.o ./graphic/axesdraw.o . . .

The main routing is in timestamp_test.c I have -g -v as compiler flags, and -v as a linker flag. No .o files are made.

Answer 1

Based on the the error given, you need to add the main function to timestamp_test.c .

Or pass the file that have the main function implemented to the compiler.
