c++ graphics.h -lbgi not found

问题:

I have this code:

#include<graphics.h>
int main( )
{
    initwindow( 700 , 700 , "MY First Program");
    circle(200, 200, 150);
    getch();
    return 0;
}

but I get this error:

ld||cannot find -lbgi|
||=== Build failed: 1 error(s), 0 warning(s) (0 minute(s), 0 second(s)) ===|

I added it to linker options and also the other things.

What should I do?

回答1:

Download this and put it in your C compiler's lib folder. Also do not forget to add in the linkers:

-lbgi
-lgdi32
-lcomdlg32
-luuid
-loleaut32
-lole32

After doing above, you would get the actual compile error belonging to initgraph() or other.

It is worked for me in Codeblocks 13.12.

If you are coding in C++11, You must know that <graphics.h> is deprecated in C++11. If you are compiling it in Turbo C++, you must use the initgraph() function and give the path to the BGI folder. For more details, check this out: http://www.programmingsimplified.com/c/graphics.h

You must include the initgraph() function. Add this:

int gd=DETECT,gm;
initgraph(&gd,&gm,"c:\\TC\BGI"); //Path where BGI folder appears
