小编sho*_*lte的帖子

我正在运行Ubuntu 11.04,当我尝试在以变量开头的路径上使用bash中的tab-completion时,我会看到一些奇怪的行为.如果我有TOP =/scratch,我尝试tab-complete:

cd $ TOP/foo

它变为:

cd\$ TOP/foo

我更喜欢它完成:cd $ TOP/foobar或cd/scratch/foobar但我会满足于它只是不改变线并要求我取消$.

有谁知道bash/readline在哪里我应该解决这个问题？

因此,有很多关于从D内部调用C API的信息,但反过来怎么样？在D中编写一个像普通C共享库一样工作的库需要做什么？这是一个简单的案例:

main.c中

extern int foo(int x);
void main() {
    printf("foo(5)=%d\n",foo(5));
}

餐饮

extern(C)
{
    int foo(int x)
    {
         return x*x;
    }
}

天真地尝试使用gcc和dmd构建和链接这些只会导致链接器错误.

链接gcc main.o foo.o:

doFoo.o: In function `no symbol':
doFoo.d:(.text+0x7): undefined reference to `_Dmodule_ref'
collect2: ld returned 1 exit status

与dmd main.o foo.o链接:
