Ubuntu 12.04 Compile link library order problem 1. Description of the phenomenon In the process of compiling Ubuntu 12.04, it is often found that the ubuntu9.10 can compile the program in the 12.04 compiler does not pass, reported "undefined reference toxxxxx" error, as shown in the following figure: 2. Problem analysis After a simple attempt, you can compile the past using the following methods: Gcc-o XPointer xpointer.c-lx11 So: What's the difference between "Gcc-lx11-o xpointer xpointer

The link sequence of the gcc LibraryPreface recently, a program developed on MIPS needs to use floating point operations. Write the bootloader and main function, and call the log floating point operation in the main function, including the math library. Then write the makefile and ld scripts. The gcc parameters use: CFLAGS =-c-march = 3081-msoft-float-fno-inline $(ENDIAN)-G0 ld parameters: LDFLAGS =-march = 3081-msoft-float-nostartfiles-lgcc-lm-lc-Wl,

What is the difference between GCC and G ++? I searched for it online and then again. There are a lot of strange ideas from around the world. Please read the document directly ..
