Question

我试图在Ubuntu 16.04上构建the OpenGL Super Bible 7th edition code samples。首先，我必须运行cmake，这似乎有效，然后我必须运行make来编译。

我相信我已经安装了glfw3和Mesa OpenGL软件包。当我执行cmake时（在安装libglfw3和libglfw3-dev之后），我收到了发现OpenGL和GLFW3的消息：

-- Found OpenGL: /usr/lib/libGL.so   
-- Checking for module 'glfw3'
--   Found glfw3, version 3.1.2

但是当我在cmake完成后执行make时，我收到了这个错误：

.../sb7code-master/src/sb7/sb7object.cpp: In member function ‘void sb7::object::render_sub_object(unsigned int, unsigned int, unsigned int)’:
.../sb7code-master/src/sb7/sb7object.cpp:212:77: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]

所以我试着看看是否安装了glfw3。我是Linux新手，所以我在网上发现了这些命令：

sudo  pkg-config --libs glfw3

吐出来：

-lglfw

然而，当我输入sudo pkg-config --libs glfw而没有3时，我得到：

Package glfw was not found in the pkg-config search path.
Perhaps you should add the directory containing `glfw.pc'
to the PKG_CONFIG_PATH environment variable
No package 'glfw' found

我尝试过：sudo ldconfig -p | grep "glfw"

吐出来：

libglfw.so.3 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libglfw.so.3

相反，sudo ldconfig -p | grep "glfw3"什么都不返回。

我下载的这个cmake文件是否设置错误告诉链接器-lglfw3什么时候应该告诉它-lglfw？或者我的库路径在某种程度上没有正确定义？

错误/过时INSERT INTO [Books] (book_id, book_author, Book_pagenumber) VALUES (50, 'Test', CAST(CAST('50a' AS VARCHAR(3)) AS SMALLINT)。

Line 28 of CMakeLists.txt是：

CMakeLists.txt

应该是：

set(COMMON_LIBS sb7 glfw3 X11 Xrandr Xinerama Xi Xxf86vm Xcursor GL rt dl)
                        ^ wat

更好的是他们应该使用find_package() to find GLFW。

ld找不到glfw3
