如何编译D和C *。o GCC的文件

I'm trying to link D and C code using the DMD and GCC compiler. What I'v tried so far is using the DMD compiler to compile the source to *.o files, using the GCC compiler to compile the C source to *.o files, and using GCC to link the to create the binary.

我尝试使用DMD和GCC编译器来链接D和C代码。到目前为止我所尝试的是使用DMD编译器来编译源到*。o文件，使用GCC编译器编译C源到*。o文件，并使用GCC来链接创建二进制文件。

However, the last step give me linker errors, giving me several "undefined symbol for architecture" errors

但是，最后一步给了我链接器错误，给了我几个“未定义的架构符号”错误。

dmd ../src/Main.d -I../src -c
gcc -c ../ext/clibs.c
gcc *.o -o Main
Undefined symbols for architecture x86_64:

      _D3std6traits15__unittest_failFiZv in Main.o
      _D3std9typetuple15__unittest_failFiZv in Main.o

I'm guessing that the D *.o file refers to symbols in the STD D library. How do I include this when linking?

我猜是D *。o文件是指STD D库中的符号。在链接时如何包括这个?

Answer I came up with, don't.
Simply use the DMD compiler for the last step

我想出了答案，不要。简单地使用DMD编译器来完成最后一步。

So, Instead of

因此,而不是

dmd ../src/Main.d -I../src -c
gcc -c ../ext/clibs.c
gcc *.o -o Main

Simply

简单的

dmd ../src/Main.d -I../src -c
gcc -c ../ext/clibs.c
dmd *.o

You still have to write a D bridging header listing all the C function you want to use with the extern (C) syntax

您仍然需要编写一个D桥接头，列出您希望使用外部(C)语法使用的所有C函数。

For example

例如

mycfile.c

mycfile.c

int myfunction() {
    return 3;
}

mycbridge.d

mycbridge.d

extern (C) int myfunction();

And then include mycbridge.d in your D source.

然后包括mycbridge。d在你的d来源。
