由于地区翻译关係,有些书籍将macro翻译成"巨集",有些翻译成"宏",为了避免混淆(我自己),所以文章内容会以英文名macro来代替中文译名 甚麽是条件编译 条件编译就是根据已经定义的macro进行选择性判断的语句,它会在compiler进行编译前完成,主要由预处理器负责 预处理器会将条件编译指令的结果告诉compiler,让他去编译指定...
This macro works and enables my GPIOA port correctly but I get two Compiler warnings. (IAR EW 7.6) macro Parameter "CONTROL_STRUCT" is used in both expanded and raw forms. (I will ignore this warning, because in this case it's right to use both forms!) 2. concatenation with "RCC_...
这一阶段,通常被视为编译器工作流程的“隐性前奏”(The Compiler's Prelude),其重要性不言而喻。而编译器(Compiler),则是这段前奏的指挥者。 3.1 预处理指令的解析 在预处理阶段,编译器首先需要识别并执行所有的预处理指令(Preprocessing Directives)。这些指令包括宏定义(Macro Definitions)、文件包含(File Inclusion...

cmake教程5-macro宏定义以及传递参数给源文件 引入在C++程序中我们经常见到如下,两个问题: 1. 输出当前程序的版本号 2. 通过cmake添加macro宏定义 出入到源文件,例如在编译opencv/caffe的时候,我们通过cmake -DUSE_CUDA=ON/OFF来确定,是否使用cuda.
Depending on which compiler you use, there should be a way to see the code after thepreprocessor(which does the macro expansion, macros are not known by the compiler at all) is done. With gcc, the option is-E. Here's a simplified example, using toy code and not the actual GTK+ macr...
Notice that the__VOS__macro is defined by the compiler, but as several compilers can co-exist in the same OS release, the version number is not reliable. SVR4 Environment Syllable Symbian OS Tru64 (OSF/1) Ultrix UNICOS UNICOS/mp
Aside from the above, there is no restriction on what can go in a macro body. Parentheses need not balance. The body need not resemble valid C code. (Of course, you might get error messages from the C compiler when you use the macro.) ...
编译器(compiler)对预处理器输出的扩展名为.i的文本文件进行解析和转换,得到扩展名为.s的文本文件,其内容是平台相关的汇编语言代码。 编译是整个程序构建过程中最复杂的阶段,可以分为5步:词法分析、语法分析、语义分析、中间代码生成及优化、目标代码生成及优化。
