gcc-D选项没有做我认为会做的事情

我正在尝试在项目中使用AsmJit。这是我使用的makefile：

CC = g++
CFLAGS = -D ASMJIT_API -I dep/

test: src/main.cpp
        $(CC) $(CFLAGS) src/main.cpp -o test.exe

尝试此操作时，我遇到了编译器错误，因此我从dep/ASMJIT/Config.h中取消了行

#define ASMJIT_API

的注释，并从makefile中删除了-D开关，所有内容都被干净地编译。我使用的是GCC4.5.3。有什么想法吗

谢谢

编辑：编译器错误

不要在-D和ASMJIT_API之间插入空格。我也一样

CFLAGS = -DASMJIT_API -Idep/

好了。

定义ASMJIT\u API和

-DASMJIT\u API

之间有区别

#define

语句将

ASMJIT_API

定义为nothing，而

使用

-D

标志，build.h的第274行扩展为

1 void assertionFailure(const char* file, int line, const char* exp);

导致编译器错误。

您遇到了哪些编译器错误？基本上是指某些内容定义不正确的错误。当设置了#define ASMJIT_API时，其他定义将按预期工作。如果它们有帮助的话，我会编辑我的帖子以包含它们。是的，如果你发布更多的代码，那会有帮助。那么，在dep/Asmjit/Build.h，第274行发生了什么？Asmjit\u API void asertionFailure（const char*file，int line，const char*exp）@kisplit-键入“maketest”时，是否将-DASMJIT_API视为生成的命令行的一部分？
