var*_*ala 6 linux haskell shared-libraries linker-errors
我正在尝试从 Haskell 源代码创建一个简单的共享库。该库由两个文件组成：Add.hs 和 lib.c。lib.c 提供了初始化和退出 haskell 运行时的函数。
添加.hs
module Add where
foreign export ccall add :: Int -> Int -> Int
add :: Int -> Int -> Int
add a b = a + b
库文件
#include <stdio.h>
#include "HsFFI.h"
#if defined(__GLASGOW_HASKELL__)
#include "Foo_stub.h"
#endif
int add(int a, int b);
void lib_init()
{
int argc = 2;
char *argv[] = { "+RTS", "-A32m", NULL };
char **pargv = argv;
hs_init(&argc, &pargv);
}
void lib_exit()
{
hs_exit();
}
我正在使用以下命令构建共享库：
ghc -c Add.hs -dynamic -fPIC -odir ./obj -stubdir ./include
gcc -c lib.c -o ./obj/lib.o -I ./include -I /usr/lib/ghc/include
ghc ./obj/lib.o ./obj/Add.o -dynamic -shared -o libadd.so
这不会给我任何错误。但是，当我尝试将我的主程序与这个库链接时，我得到以下输出：
gcc test.c -o ./obj/test.o -ladd -L. -o test-exe

经过更多资源后，我发现共享库必须显式链接到 Haskell rts 库。该文件是/usr/lib/ghc/rts/libHSrts-ghc8.6.5.so。我将构建库的命令更改为以下内容：
ghc ./obj/lib.o ./obj/Add.o -dynamic -shared -lHSrts-ghc8.6.5 -L/usr/lib/ghc/rts -o libadd.so
并使用以下命令构建了加载该库的测试程序：
gcc test.c -o ./obj/test.o -ladd -L. -Wl,-rpath,. -o test-exe
这很好用！
