包含在c中的FreeImage

Question

有没有办法在我的c测试程序中包含http://freeimage.sourceforge.net/index.html而不用先安装库？由于某些memset，它无法编译。

这是我的C代码。有没有办法让它工作呢？请尝试编译它，并告诉我如何做，如果它的工作？

#define NAZIV_DATOTEKE 50
#include <stdio.h>
#include "FreeImage.h"


void FreeImageErrorHandler(FREE_IMAGE_FORMAT fif, const char *message);
FIBITMAP* GenericLoader(const char* lpszPathName, int flag);

int main(){
    FreeImage_Initialise();
    FIBITMAP *dib, *ptr;
    char ulaz_slika[NAZIV_DATOTEKE] = "bmp_24.bmp";
    char izlaz_slika[NAZIV_DATOTEKE] = "free.bmp";  //podrazumevana vrednost

    dib = GenericLoader(ulaz_slika, 0);
    //slika = FreeImage_Load(FIF_BMP, "bmp_24.bmp", BMP_DEFAULT);
    FreeImage_SetOutputMessage(FreeImageErrorHandler);
    if (dib) {
        printf("Ucitan \"%s\".\n", ulaz_slika);
    }

    FREE_IMAGE_FORMAT fif = FreeImage_GetFileType(ulaz_slika, 0);
    if ((fif != FIF_BMP) && (fif != FIF_ICO) && (fif != FIF_JPEG) && (fif != FIF_PNG) && (fif != FIF_TIFF)){
        printf("Format slike nije podrzan.\n");
        return 1;
    }


    ptr = FreeImage_ConvertTo24Bits(dib);
    FreeImage_SetOutputMessage(FreeImageErrorHandler);

    // (the second argument is currently not used by FreeImage)
    fif = FreeImage_GetFileType(lpszPathName, 0);
    if(fif == FIF_UNKNOWN) {
        // no signature ?
        // try to guess the file format from the file extension
    fif = FreeImage_GetFIFFromFilename(lpszPathName);
    }
    // check that the plugin has reading capabilities ...
    if((fif != FIF_UNKNOWN) && FreeImage_FIFSupportsReading(fif)) {
        // ok, let's load the file
        FIBITMAP *dib = FreeImage_Load(fif, lpszPathName, flag);
        // unless a bad file format, we are done !
        return dib;

不你不能。为了编译源代码，链接器需要这个库。
