在Eclipse中编译C / GTK [英] Compiling C/GTK within Eclipse
问题描述
我认为第一个问题是当我尝试在Eclipse中编译时，主要的GTK include文件被引用不同。非Eclipse版本可以使用（如示例）编译：
#include< gtk / gtk.h>
但是，在Eclipse中，这不起作用。我需要将其更改为：
#include> gtk-2.0 / gtk / gtk.h>
然后可以找到包含文件，但是编译过程然后开始抛出关于GtkWidget类型的错误。例如：
#include> gtk-2.0 / gtk / gtk.h>
int main（int argc，char * argv []）
{
GtkWidget * window;
gtk_init（& argc，& argv）;
window = gtk_window_new（GTK_WINDOW_TOPLEVEL）;
gtk_widget_show（window）;
gtk_main（）;
return 0;
}
导致这些错误：
make all
构建文件：../src/main.c
调用：GCC C编译器
gcc -O0 -g3 -Wall -c -fmessage-length = 0 -MMD -MP -MFsrc / main.d-MTsrc / main.d-osrc / main.o../src/main.c
../src/main.c：在函数'main'中：
../src/main.c:7：错误：'GtkWidget'未声明（在此函数中首次使用）
../src/main.c:7：错误：（每个未声明的标识符仅报告一次
../src/main.c:7：错误：对于其中显示的每个功能）
../src/main.c:7：error：'window'undeclared（在此函数中首次使用）
../src/main.c:9：warning：隐式声明函数'gtk_init'
../src/main.c:11：warning：隐式声明函数'gtk_window_new'
../src/main.c:11：错误：'GTK_WINDOW_TOPLEVEL'未声明（在此函数中首次使用）
../src/main.c:12：warning：隐式声明函数'gtk_widget_show'
../src/mai nc：14：warning：隐式声明函数'gtk_main'
make：*** [src / main.o]错误1
不知道该怎么做任何帮助将非常感谢。
右键单击Eclipse项目并选择属性。从配置下拉列表中，选择 [所有配置] 。然后在工具设置选项卡上选择 GCC C编译器（默认），并将以下内容添加到结尾命令行模式（专家设置）框：
`pkg-config --cflags --libs gtk + -2.0`
为 GCC C Linker 选项执行同样的操作。
如果您不想使用gtk-2.0启动包含路径，也可以像建议的aardvark一样添加include目录（/usr/include/gtk-2.0）。
I'm fiddling around with the C/C++ version of Eclipse to build a simple GTK app. However, I can't seem to be able to compile a GTK sample from within Eclipse. I can compile a simple Hello World style test app, so I know the tool chain itself is working. However, the moment I start adding GTK into the mix the compiler comes up with errors. The funny thing is that I can compile the examples outside the Eclipse environment just fine. E.g., I'm using the examples on this page and following the instructions given there let me build a working binary.
I think the first problem is that the main GTK include file is referenced differently when I try to compile within Eclipse. The non-Eclipse version I can compile with (as in the example):
#include <gtk/gtk.h>
However, within Eclipse this doesn't work. I need to change it to:
#include <gtk-2.0/gtk/gtk.h>
The include file can then be found but the compilation process then starts to throw errors about the GtkWidget type. E.g.:
#include <gtk-2.0/gtk/gtk.h>
int main( int argc, char *argv[] )
{
GtkWidget *window;
gtk_init (&argc, &argv);
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
gtk_widget_show (window);
gtk_main ();
return 0;
}
Results in these errors:
make all

make: *** [src/main.o] Error 1
Not sure how to go about this. Any assistance would be very much appreciated.
Right click the Eclipse project and select properties. From the Configuration drop down, select [ All configurations ]. Then on the Tool Settings tab select GCC C Compiler (default) and add the following to the end Command line pattern (Expert settings) box:
`pkg-config --cflags --libs gtk+-2.0`
Do the same thing for the GCC C Linker option.
If you don't want to start your include paths with gtk-2.0 than also add the include directory (/usr/include/gtk-2.0) like aardvark suggested.
