在Linux Ubuntu上编译google liquidfun时出错

Question

我正在尝试按照这个页面上的说明在ubuntu20.10上编译LiquidFun1.10：https://google.github.io/liquidfun/Building/html/md__building_linux.html

当我运行该命令时：

cd liquidfun/Box2D
cmake -G'Unix Makefiles'
make

我得到了各种错误，构建失败。这是屏幕输出：

cmake -G'Unix Makefiles'
CMake Warning:
  No source or binary directory provided.  Both will be assumed to be the
  same as the current working directory, but note that this warning will
  become a fatal error in future CMake releases.


CMake Warning (dev) at /usr/share/cmake-3.16/Modules/FindOpenGL.cmake:275 (message):
  Policy CMP0072 is not set: FindOpenGL prefers GLVND by default when
  available.  Run "cmake --help-policy CMP0072" for policy details.  Use the
  cmake_policy command to set the policy and suppress this warning.

  FindOpenGL found both a legacy GL library:

    OPENGL_gl_LIBRARY: /usr/lib/x86_64-linux-gnu/libGL.so

  and GLVND libraries for OpenGL and GLX:

    OPENGL_opengl_LIBRARY: /usr/lib/x86_64-linux-gnu/libOpenGL.so
    OPENGL_glx_LIBRARY: /usr/lib/x86_64-linux-gnu/libGLX.so

  OpenGL_GL_PREFERENCE has not been set to "GLVND" or "LEGACY", so for
  compatibility with CMake 3.10 and below the legacy GL library will be used.
Call Stack (most recent call first):
  CMakeLists.txt:120 (find_package)
This warning is for project developers.  Use -Wno-dev to suppress it.

还有其他人遇到过这个问题吗？

Answer 1

他们使用重新定义的add_library命令：liquidfun/Box2D/CMakeLists.txt:101来玩肮脏的游戏。而且他们似乎忘记了，一些FindXXX.cmake脚本可能会使用这个add_library创建导入的目标。

您可以尝试删除此重新定义:删除从function(add_library name)到endfunction(add_library)的行。但要做好准备，一些库将在未记录的位置创建。

为了克服警告“没有提供源代码或二进制目录”。将.参数添加到cmake调用中：

cmake -G'Unix Makefiles' .
