如何使用DMD编译/链接静态库

标签: linker d dmd

每当我使用DMD构建一个静态库时,我都可以将它链接到我的应用程序并且编译得很好但是在应用程序中随时调用库我得到:

Segmentation fault (core dumped)

用于构建库我

# $(FILE) for each file in "find source -name "*.d"
# $(OBJ) is $(FILE) with the extension ".o"
# $(IMP) is $(FILE) with the extension ".di"
dmd -O -d -m64 -L-ldl -m64 -Isource -c $(FILE) -ofbuild/$(OBJ)

ar rcs ./lib/libvibe.d-dmd.a build/*
ranlib ./lib/libvibe.d-dmd.a

dmd -O -d -m64 -L-ldl -m64 -Isource -c -o- $(FILE) -Hfimport/$(IMP)

并用于构建应用程序

SRC = $(shell find src -name "*.d")
dmd -debug -odbuild -I../../vibe.d/source -L-L../../vibe.d/lib -L-lvibe.d-dmd $(SRC) -ofbin/test

我做错了什么?


更新

将vibe.d编译为libvibe.d-dmd.a

dmd -g -lib -oflib/libvibe.d-dmd.a $(SOURCES) -L-levent_pthreads -L-levent -L-lssl -L-lcrypto

示例代码:

import vibe.core.file;
void main()
{
  openFile("test.d", FileMode.Read);
}

编译示例

dmd -g test.d vibe.d/lib/libvibe.d-dmd.a -Ivibe.d/source

还有一些gdb输出:

为什么不使用dmd -lib -oflibmylib.a file1.d ...

你能做的最好的事情就是运行GDB,看看为什么你的应用程序会出现段错误。如果您发现segfault的原因是从您的库中取消引用函数指针,那么很可能您是对的并且链接出现了问题。

如果你不熟悉GDB,这里有一篇简单的文章:http://www.unknownroad.com/rtfm/gdbtut/gdbsegfault.html

关于这个主题,Wiki4D还有一篇很好的文章。

以下是整个会话如何从两个文件libdstlib.adstlib/foo.d中编译库dstdlib/bar.d

dejan@homeserver:~/work/dstlib> ls -R
.:
driver.d  dstlib

./dstlib:
bar.d  foo.d
dejan@homeserver:~/work/dstlib> dmd -lib -oflibdstlib.a dstlib/*.d
dejan@homeserver:~/work/dstlib> dmd driver.d libdstlib.a
dejan@homeserver:~/work/dstlib> ./driver
w: 80, h: 40
dejan@homeserver:~/work/dstlib> cat driver.d dstlib/foo.d dstlib/bar.d
module driver;
import std.stdio;
import dstlib.bar;

void main()
{
    auto rect = getRectangle();
    rect.display();
}    
module dstlib.foo;
import std.stdio : writefln;
struct Rectangle
{
    int width, height;
    void display()
    {
        writefln("w: %s, h: %s", width, height);
    }
}    
module dstlib.bar;
import dstlib.foo;

Rectangle getRectangle()
{
    return Rectangle(80, 40);
}
