Can't find ZLIB and PNG when compiling

[edwardloveall]

Hi. I'm on Mac OS 10.9 and I'm getting this issue when I run cmake .

-- Boost version: 1.54.0
-- Found the following Boost libraries:
--   iostreams
--   system
--   filesystem
--   program_options
-- Boost version: 1.54.0
-- Found the following Boost libraries:
--   unit_test_framework
-- Could NOT find ZLIB (missing:  ZLIB_INCLUDE_DIR) 
CMake Error at /usr/local/Cellar/cmake/2.8.11.2/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:108 (message):
  Could NOT find PNG (missing: PNG_LIBRARY PNG_PNG_INCLUDE_DIR)
Call Stack (most recent call first):
  /usr/local/Cellar/cmake/2.8.11.2/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:315 (_FPHSA_FAILURE_MESSAGE)
  /usr/local/Cellar/cmake/2.8.11.2/share/cmake/Modules/FindPNG.cmake:71 (find_package_handle_standard_args)
  CMakeLists.txt:40 (find_package)

Any thoughts? As far as I can tell I have those two libraries installed, but I don't actually know how to confirm.

Well, I could ask Deep Thought for an answer... ;)

Now serious: There were some changes with the CMake files finding required packages. Can you try if it works with the CMakeLists.txt files from 70364bc?

[edwardloveall]

It did indeed work with that commit. I have a different make issue now which I'll post about.

[edwardloveall]

Oh. Duh. I get the 42 joke now. Nice

[m0r13]

Haha yes, I waited some time for the big 42 to do this.

I would let this issue opened because I also had this problem on another system. So I guess you are not the only one who might have this problem.

Until then you can use mapcrafter with older CMakeLists.txt files. It would be better if you could copy the old CMakeLists.txt files into the new sources so you can also get new commits (when I try to solve your other problem).

edwardloveall: I just tested on my 10.9 system and cmake found zlib and libpng.

Whats the output of the following commands?
brew info libpng
brew doctor

What version of xcode do you have installed?

[edwardloveall]

$ brew info libpng

libpng: stable 1.5.14

Good call. Updating brew and installing Command Line Tools now.

That did it! Thanks @thorerik

I guess we can close this now.
