用唔倒個 library

同事話唔知點整個 .so 來比佢個program call download 返來果個 library, 我唯有寫個簡單call test 做例子. 乜而家大學唔教呢d 架咩?

compile 個 .so 同個 test
g++ -shared -I../../C/FreeImage/Dist dyncall.cpp libfreeimage.a -o dyncall.so
gcc -O3 testcall.cpp dyncall.so -o testcall
-------------
dyncall.cpp

#include <stdio.h>
#include <FreeImage.h>

int dyncall();

main()
{
        dyncall();
}

int dyncall()
{
        bool fBigEndian;

        fprintf(stderr,"test 1 : start\n");

        fBigEndian = !FreeImage_IsLittleEndian();

        FreeImage_Initialise();

        fprintf(stderr,"test 2 : end\n");
}

calltest.cpp

#include <stdio.h>

int dyncall();

main()
{
        dyncall();
}
