我刚刚开始使用OpenGL SuperBible第6版,我很难在Ubuntu 14.04上编译任何样本。我安装了dev packages依赖项:
sudo apt-get install xorg-dev libglu1-mesa-dev libglfw-dev nvidia-331-dev cmake
我从skaslev的github抓起了gl3w,运行了python脚本,然后sudo将gl3w.h和glcorearb.h复制到/ usr / include / GL /
我从SuperBible github和媒体文件中抓取样本,将媒体文件解压缩到bin / media中。然后我回到sb6文件的根目录(在我的情况下,该文件夹名为sb6code_2013_11_10),然后运行:
cmake .
make
cmake 工作正常,但 make 会抛出:

所以我决定尝试编写自己的小程序,基于清单2.1中的书:
#include "sb6.h"
class my_application : public sb6::application
{
void init()
{
static const char title[] = "OpenGL SuperBible - Listing 2.1";
sb6::application::init();
memcpy(info.title, title, sizeof(title));
}
void render(double currentTime)
{
static const GLfloat red[] = {1.0f, 0.0f, 0.0f, 1.0f};
glClearBufferfv(GL_COLOR, 0, red);
}
};
DECLARE_MAIN(my_application)
然后我尝试编译它:
g++ listing2.1.cpp -o listing2.1 -lGL -lGLU -lX11 -lglfw -D_LINUX
但这给了我一组不同的错误:

我在sb6.h中检查过gl3w.h是否包含在任何OpenGL依赖项之前,这是真的,所以我真的不确定下一步该尝试什么。似乎是一个链接问题,但是我已经很长一段时间了,因为我一直在用C ++开发,而且我不确定下一步该尝试什么。
更新
我按照didierc的建议,发现有一个带有gl3w.h和glcorearb.h的sb6code_2013_11_10 / include / GL文件夹。我暂时将GL文件夹移出sb6code_2013_11_10 / include,然后再次运行 cmake 和 make ,然后收到以下错误:

然后我想"好的,那么也许我会尝试使用sb6包附带的gl3w.h和glcorearb.h。"所以我恢复了GL文件夹,然后删除了gl3w.h和glcorearb.h我之前使用python脚本生成并放在/ usr / include / GL中。在 cmake 和 make 后,我收到此错误:

我能够使用sb6示例代码找到构建问题的解决方案。事实证明,样本代码中包含的CMakeLists.txt中存在错误,其中第13行是
trouble trying to build opengl superbible example code
https://github.com/openglsuperbible/sb6code/issues/12
https://github.com/openglsuperbible/sb6code/issues/8
通过该修复,sb6示例代码现在为我编译。但是,当我尝试在我自己的示例代码中使用sb6.h(在上面的 my_application 中列出)时,我仍然得到
In file included from sb6ext.h:29:0,
from sb6.h:71,
from listing2.1.cpp:1:

我能够通过修复CMakeLists.txt中的错误来解决sb6示例代码编译问题,其中第13行是

https://github.com/openglsuperbible/sb6code/issues/8
当我在自己的代码中使用sb6.h时,我还没有解决我的编译问题,但是当我这样做时会更新这个答案
