OSX El Capitan makefont build error #93

Closed bakpakin closed 8 years ago

bakpakin commented 8 years ago

When I try to build freetype on OSX El Capitan, it seems to build most of the project, but fails on linking the makefont executable.

Output:

All of the errors seem to be glfw3 referencing undefined OSX framework symbols in CoreFoundation, CoreVideo, and IOKit. I'm not sure if this is an error with glfw3 or freetype-gl, but its not compiling. I tried adding the missing frameworks via -framework compiler flags in CMakeLists.txt, but it didn't help.

I'm also using El Capitan and I do not have such problem. How did you install glfw3 ? (I installed it through homebrew)

bakpakin commented 8 years ago

Same.

bakpakin commented 8 years ago

Right now I'm trying to install glfw through macports to see if that changes anything.

bakpakin commented 8 years ago

So with a bit of poking around, I think the problem is that cmake can't find glfw, and the Findglfw3.cmake that I provided was the wrong solution. I took a step back and did a standard cmake build from the the repository just as I cloned it.

CMake Error at CMakeLists.txt:81 (FIND_PACKAGE):
  By not providing "Findglfw3.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "glfw3", but
  CMake did not find one.

  Could not find a package configuration file provided by "glfw3" with any of
  the following names:

    glfw3Config.cmake
    glfw3-config.cmake

  Add the installation prefix of "glfw3" to CMAKE_PREFIX_PATH or set
  "glfw3_DIR" to a directory containing one of the above files.  If "glfw3"
  provides a separate development package or SDK, be sure it has been
  installed.

So, as you can see, glfw3 can't be found. I think this is me be bad at cmake, but I'm not sure how to proceed. glfw3 is installed through homebrew.

Yes, I remember this issue (#78). The solution is to:

ln -s /usr/local/lib/cmake/glfw /usr/local/lib/cmake/glfw3
bakpakin commented 8 years ago

Ah, thank you. I just managed to make a custom Findglfw3.cmake that worked, but that looks easier.

rougier commented 8 years ago

Ok. Don't forget to close the issue if you think it is solved.
