I don't think so, more it seems, I'm missing a library. My minimum test
example tells "undefined reference to jpeg_std_error":
//-------------------------------------------
#include <stdio.h>
#include <jpeglib.h>
int main (void)
{
struct jpeg_compress_struct cinfo;
struct jpeg_error_mgr jerr;
cinfo.err = jpeg_std_error (&jerr);
return 0;
}
//-------------------------------------------
The command line for building:
g++ -mwindows -o"Fl_Test.exe" ./Main.o -lfltk -lfltk_images
-lfltk_jpeg -lfltk_png -lfltk_z -lole32 -luuid -lcomctl32 -lwsock32 -lsupc++
tells me:
./Main.o(.text+0x31): In function `main':
D:/Daten/TANtec/Fl_Studio/Fl_Jpeg_Studio/Debug/../Main.cpp:11: undefined
reference to `jpeg_std_error(jpeg_error_mgr*)'
make: *** [Fl_Test.exe] Error 1
jpeg_std_error should be inside of fltk_jpeg, shouldn't it?
There is no error of not found library and I don't see a library
missing. But where is the reference to jpeg_std_error()? I'm really out
of ideas, changing order of librarys also had no effect. Maybe C++ name
mangling doesn't find the function (don't know very much about this
theme, but defining "-D__cplusplus" wasn't the trick ;o).
Anyone knowing more?
