我碰到了green,这是 Framebuffer 的 PDF 查看器。我想编译它,但我没有成功,虽然我已经安装了所有依赖项......
我得到的错误是:

显然他找不到 GdkPixbuf,但是这个构造定义在:
# ls /usr/include/gdk-pixbuf-2.0/gdk-pixbuf/gdk-pixbuf.h
/usr/include/gdk-pixbuf-2.0/gdk-pixbuf/gdk-pixbuf.h
当我向文件 sdl.c 添加以下行时:
#include <gdk-pixbuf/gdk-pixbuf.h>
我对以下错误感到“欢迎”:
# make
cc -Os -Wall -c sdl.c $(pkg-config poppler-glib --cflags) $(sdl-config --cflags) -o sdl.o
sdl.c:20:35: fatal error: gdk-pixbuf/gdk-pixbuf.h: No such file or directory
compilation terminated.
make: *** [sdl.o] Error 1
那么我的问题是,我如何“说服” gcc 编译这段代码?
在此先感谢,奥兹
更新:将完整路径添加到 gdk-pixbuf/gdk-pixbuf.h 产生:
