[英]How can I link with gcc and SDL_image library?
I have the following script: 我有以下脚本:
gcc -I /Library/Frameworks/SDL2.framework/Headers \
-F /Library/Frameworks/ -framework SDL2 test.c
that successfully compiles the following source code: 成功编译以下源代码:
#include <SDL.h>
//#include "SDL_image.h"
int init();
int loadMedia();
void close();
SDL_Window* gWindow = NULL;
SDL_Surface* gScreenSurface = NULL;
SDL_Surface* gHelloWorld = NULL;
int init()
{
int success = 1;
if(SDL_Init(SDL_INIT_VIDEO) < 0)
{
printf("SDL could not initialize! SDL_Error: %s\n", SDL_GetError());
}
}
int main(int argc, char* args[])
{
return 0;
}
My question is how do I compile this with the added library SDL_image? 我的问题是如何使用添加的库SDL_image编译它? Would it be something like this?
它会是这样的吗?
gcc -I /Library/Frameworks/SDL2.framework/Headers \
-I /Library/Frameworks/SDL_image.framework/Headers \
-F /Library/Frameworks/ -framework SDL2 test.c
When I try this I get the following error: 当我尝试这个时,我收到以下错误:
In file included from test.c:2:
/Library/Frameworks/SDL_image.framework/Headers/SDL_image.h:27:10: fatal error:
'SDL/SDL.h' file not found
`#include <SDL/SDL.h>`
You could do: 你可以这样做:
gcc -L/libs/path -I/headers/path -lSDL2 -lSDL2_image
gcc -L / libs / path -I / headers / path -lSDL2 -lSDL2_image
In this case, use #include "..."
for your SDL2 headers inclusion. 在这种情况下,请使用
#include "..."
包含SDL2标头。
If you installed SDL2 with a package manager, the previous command is reduced to: 如果使用程序包管理器安装SDL2,则上一个命令将缩减为:
gcc -lSDL2 -lSDL2_image
gcc -lSDL2 -lSDL2_image
since the path of SDL2 directory is then known to the compiler. 因为编译器已知SDL2目录的路径。 In that case you should use
#include <...>
. 在这种情况下,您应该使用
#include <...>
。
You should consider writing a Makefile for your project. 您应该考虑为您的项目编写Makefile。 It would become easier to compile as your project grows.
随着项目的增长,编译会变得更容易。
