Hello, everyone, crossing, last time we were talking about GCC optimization-related content. This time we're going to talk about how to use GCC for debugging,Gossip Hugh, words return to the positive. Let's talk about GCC together!Crossing, as we all know, people sometimes make mistakes when they write code. Sometimes it causes a compile error, sometimes it cause

The MacBook is defined as clang, while the Orthodox GNU GCC can only use gcc-7 (gcc 7), however, if you modify the/usr/bin link, it is also prone to system errors because the Mac's toolchain and GCC (clang) are highly integrated, searching for , found that a master through the clever use of alias to solve the problem p

In ARM-based embedded system development, there are two GCC tool chains that often use cross-Compilation:The main difference between ARM-Linux-* and arm-elf-* is that they use different C-library files. Arm-Linux-* useWhile arm-elf-* generally uses uclibc/UC-libc or RedHat for embedded systems.Newlib. glibc. Both uclibc, UC-libc, and newlib are C language library files.Glibc is developed for PC, and uclibc/UC-libc is a small size compatible with glibc
