Are you certain the "current working directory" (cwd)
is set to the directory where the foo.jpg resides?
It might not be if you just double-click on it
(eg. desktop or folder browser).
Try adding some error checking to the app
to show if the file can be accessed, and if not,
showing what the cwd is. e.g.
#include <FL/Fl.H>
#include <FL/Fl_Window.H>
#include <FL/Fl_Shared_Image.H>
#include <FL/Fl_JPEG_Image.H>
#include <FL/Fl_Box.H>
#include <FL/fl_draw.H>
#include <FL/fl_ask.H>
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <errno.h>
#ifdef WIN32
#include <direct.h>
#define getcwd _getcwd
#else
#include <unistd.h>
#endif
void CheckIfExists(const char *filename) {
FILE *fp = fopen(filename, "r");
if ( !fp ) {
char cwd[4096];
getcwd(cwd, sizeof(cwd));
if ( filename[0] != '\\' && filename[0] != '/' ) {
fl_alert("Cannot not open '%s' in directory %s: %s",
filename, cwd, strerror(errno));
} else {
fl_alert("Cannot not open '%s': %s\n", filename, strerror(errno));
}
exit(1);
}
}
int main() {
fl_register_images();
CheckIfExists("foo.jpg");
Fl_Window win(720,486);
Fl_Box box(10,10,720-20,486-20);
Fl_JPEG_Image jpg("foo.jpg");
box.image(jpg);
win.show();
return(Fl::run());
}
