c - 我的交叉编译器出了什么问题？

Question

我正在尝试编译一个基本程序，我可以在我的 Mac 上进行交叉编译。我运行的是 Mac OS X Mavericks。我的交叉编译器是arm-elf-gcc-4.7.3。我编写了一个简单的测试程序，如下所示:

int main()
{
    ;
    return 0;
}

当我运行/opt/local/bin/arm-elf-gcc-4.7.3 -o test test.c 时，我收到这些错误。

test.c:4:Unknown pseudo-op: .global
test.c:4:Rest of line ignored. 1st junk character valued 109 (m).
test.c:5:Unknown pseudo-op: .type
test.c:5:Rest of line ignored. 1st junk character valued 109 (m).

我的交叉编译器出了什么问题？

Answer 1

编译器使用了错误的汇编器。我必须用 -B/opt/local/arm-elf- 指定前缀
