auth branch does not compile on Linux

[emilis]

• I am using Ubuntu 13.04.
• Using auth branch with last commit being 27eae8d (more auth)
• I have tried installing build dependencies for curl – didn't help.

$ make
-- Using X11 for window creation
-- Using GLX for context creation
CMake Error at CMakeLists.txt:26 (find_package):
  By not providing "Findcurl.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "curl", but
  CMake did not find one.

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

    curlConfig.cmake
    curl-config.cmake

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

@emilis: It turns out that (at least on Ubuntu) the CMake file for Curl is called FindCURL, not Findcurl. If you change curl to CURL on line 26, cmake should work.

A side note: After changing this, I still couldn't compile the auth branch. strlcat was undefined in auth.c. I tried installing libbsd-dev, but it didn't work.

@Aaron1011 fogleman already fixed the CURL dependency.

Now I am also stuck with the libbsd problem. Searched a little bit: it seems there is no Find...cmake file for libbsd. Not sure how to work around this, since I have no experience with CMake.

[fogleman]

Don't worry about libbsd, I'll use something other than strlcat

[emilis]

@fogleman Was searching for some CMake hack. Stopped searching. Now waiting for a commit :)

[emilis]

Fixed, so closing.

I have a similar CURL problem on Linux Mint 14 (I have curl installed)

cmake .

-- Could NOT find Doxygen (missing:  DOXYGEN_EXECUTABLE) 
-- Using X11 for window creation
-- Using GLX for context creation
CMake Error at /usr/local/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:108 (message):
  Could NOT find CURL (missing: CURL_LIBRARY CURL_INCLUDE_DIR)

To solve had to install libcurl:

sudo apt-get install libcurl4-openssl-dev

Hello, I build it success as your tip! But when I use ./craft to run it on ubuntu12.04 LTS, occured Segmentation fault (core dumped), how to solve it ? thank you!

hl@lilei:/myworld/Craft$ ls
builder.py cmake_install.cmake deps README.md src world.pyc
CMakeCache.txt CMakeLists.txt LICENSE.md server.py textures
CMakeFiles craft Makefile shaders world.py
hl@lilei:/myworld/Craft$ ./craft
Segmentation fault (core dumped)
hl@lilei:~/myworld/Craft$

@FanChael Could you provide a backtrace or core dump? Might help in reproducing the problem.

Simplest way is to

gdb ./craft
> run
Segmentation fault (core dumped)
> bt

(although I'm not sure the makefile compiles in debug symbols by default, so you might have to change that too.)

I have the same problem. Compiled on Ubuntu 12.04 and the program immediately crashes with a segmentation violation. Here is some info, as per the request above (I added the -g flag when compiling).

I'd love to get this working to do some hobby AI... ;-) Thanks in advance.
