Should I still define _GNU_SOURCE when I compile with -std=gnu99?

阅读更多关于 Should I still define _GNU_SOURCE when I compile with -std=gnu99?

问题 I use some GNU extensions and realized that if I set gnu99 as C-standard to use, I can omit #define _GNU_SOURCE. Does gnu99 imply the _GNU_SOURCE or is it still safer to use it or mandatory to avoid problems? 回答1: You should differentiate between language and library features; -std=gnu99 enables GNU language features, _GNU_SOURCE enables GNU library features. I suggest you to define _GNU_SOURCE if you use any library features, so it's clear for readers of your code. Also, this might make

阅读更多关于 GNU Global and GTAGS can't find class definitions

问题 I'm having trouble getting global to find class/struct definitions. I can find them with exuberant ctags and with cscope. All tag files are built from the same source file list. I configured and built global, et.al., only specifying --prefix. configure did find exhuberant and is using it. I've been trying global periodically over the years and it's always had this problem. Any ideas? thanks, davep 回答1: Just export this variable and that should pretty much do. From the man page for gtags -
