Compile the GTK2.0 Program-general Linux technology-Linux programming and kernel information. The following is a detailed description. GTK is the c/c ++ language graphics library used to develop Gnome windows. I had a hard time on the Ubuntu machine and copied the online tutorial code to compile it on the local machine. Code File Name: t1.c. Follow the tutorial to compile with the following command:
Gcc t1.c 'pkg-config -- cflags -- libs gtk +-2.0'
Compilation result: gtk/gtk. h is not found.
Because my Ubuntu is a Gnome system, I thought that gtk + 2.0 development programs (header files and library files) should have been installed on the computer. Otherwise, if you develop a gtk + 2.0 program on Ubuntu, you need to install the corresponding header file and library. In the console window, enter sudo apt-get install libgtk2.0 *. All files required for gtk + 2.0 are downloaded and installed. Apply the compilation command again: gcc t1.c 'pkg-config -- cflags -- libs gtk +-2.0, compile and run.
Pkg-config is a program used to manage packages. On the console, enter the running result of pkg-config -- cflags -- libs gtk +-2.0:
It can be seen that the output text includes all the options required for gcc to compile gtk + 2.0 (header file directory and library file ).
Note that the gcc t1.c 'pkg-config -- cflags -- libs gtk +-2.0 ', the quotation marks on both sides of pkg-config -- cflags -- libs gtk +-2.0 are not real quotation marks, but the character on the leftmost side of the keyboard number. If a single quotation mark is used incorrectly, gcc cannot use the text generated by pkg-config -- cflags -- libs gtk +-2.0 as the compilation option.
