Question

我正在尝试在项目中使用AsmJit。这是我正在使用的makefile：

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

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

尝试此操作时出现编译器错误，因此我从dep / AsmJit / Config.h中取消注释了行#define ASMJIT_API，并从makefile中删除了-D开关，并且干净地编译了所有内容。我正在使用gcc 4.5.3。有什么想法吗？

感谢。

编辑：编译器错误

Answer 1

#define ASMJIT_API和-DASMJIT_API之间存在差异。

#define语句将ASMJIT_API定义为空，the -D flag defines the preprocessor constant as 1。

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);

导致编译错误。

Answer 2

请勿在-D和ASMJIT_API之间插入空格。同上-I

CFLAGS = -DASMJIT_API -Idep/

你去。

gcc -D选项没有做我想的那样
