c10t does not compile (anymore)

[Tmkrth]

Hello everyone.

Since two weeks or so i cannot compile c10t anymore. cmake tells

CMake Error at /usr/share/cmake/Modules/FindBoost.cmake:1197 (message):
  Unable to find the requested Boost libraries.

  Boost version: 1.46.1

  Boost include path: /usr/include

  The following Boost libraries could not be found:

          boost_thread
          boost_filesystem
          boost_system

  No Boost libraries were found.  You may need to set BOOST_LIBRARYDIR to the
  directory containing Boost libraries or BOOST_ROOT to the location of
  Boost.
Call Stack (most recent call first):
  CMakeLists.txt:30 (find_package)

and

CMake Warning (dev) at CMakeLists.txt:56 (add_subdirectory):
  The source directory

    /home/tmk/c10t/libs/unc

  does not contain a CMakeLists.txt file.

  CMake does not support this case but it used to work accidentally and is
  being allowed for compatibility.

Running cmake with smth like --BOOST_LIBRARYDIR=/usr/lib64 or --BOOST_LIBRARYDIR=/usr/include/boost , where on my system boost libs are present, does not change anything. Maybe my syntax is wrong, does anyone has a command example for running cmake with arguments?

Setting "set(Boost_USE_STATIC_LIBS TRUE)" to FALSE in the CMakeLists.txt and running cmake with "-Wno-dev" finds the boost libraries and does not complain about the missing CMakeLists.txt, although this file exists in c10t/

There is a directory called "unc" in c10t/libs/ but no unc.hpp

I tried this on Suse 12.1, Suse 11.4 and Lubuntu 11.10, all x86_64, whereas on Lubuntu it found the boost libs without the need of editing the CMakeLists.txt file.

Does anyone else experience this? What could I do?

See README, there is a submodule you need to initialize.

[FabianN]

I just updated and having similar issues

I tried to re-do it from scratch, followed the steps in the readme closely, including the submodules part. This is a copy of my last attempt:

I get the same error as FabianN, trying to build on an ubuntu system.

[udoprog]

Which version of boost are you using?

The requested position is a boost compatibility hack, if you check it out there is an #if macro with two alternatives, it chooses the wrong functionality for your version.

This is due to a upgrade from filesystem v2 to v3 somewhere around boost 1.45

[cal]

cal@pumpkin:~$ apt-cache show libboost-all-dev | grep Version
Version: 1.42.0.1ubuntu1

Looks like I have 1.42~ish

cal@pumpkin:~$ cat /etc/lsb-release 
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=10.10
DISTRIB_CODENAME=maverick
DISTRIB_DESCRIPTION="Ubuntu 10.10"

Also I guess I haven't upgraded my 'buntu in a bit, looks like the more recent release(s) have 1.46+

Anyway, this is how i made it compile:

cal@pumpkin:/var/minecraft/c10t$ git diff
diff --git a/src/fileutils.hpp b/src/fileutils.hpp

+#define BOOST_FSv2 ((BOOST_VERSION / 100) <= 1041)

 namespace fs = boost::filesystem;

It compiles just fine, but still throws a few warnings ...

[cal]

Doesn't render though, looks like the same problem as #231.

I also updated to the latest ubuntu (boost 1.46), it compiles without the code change, I get the same warnings, and the resulting binary doesn't render.

[uap-universe]

@Tmkrth is your issue resolved? Does the submodule thing work for you now?

I would like to close this then and continue the discussion about libboost or other reasons why c10t does not compile or work in the respective issue reports.

[Tmkrth]

No, the submodule thing is not working. Still I can't compile anything newer than 1bed5b0dae9fd1a1b2d1e2fc0c30d8e65d75bf2e

[uap-universe]

And what have you already tried out to get it working?

What error messages appear when you type "git submodule init" or "git submodule update"? I need some information to localize a possible error. To be honest, I still believe you haven't loaded the submodule yet with the respective git commands ;)

[Tmkrth]

Well you are right, somehow I missed that there are two git submodule commands to be executed, which I ask pardon for. It pulls, compiles and renders as nice as c10t just does :-)

[chum]

Are the boost and the unc problems related? I did not see any boost problem, but am having the missing unc.hpp problem, vis:

This is the first time I've ever tried to build c10t, so I can't comment on differences from earlier builds. I'm also not fluent with make & friends -- I've used them before, but typically build via an IDE, so have been shielded from the low level stuff for several years (decades!)

I'm following the steps on this page:

https://github.com/udoprog/c10t/wiki/Building-on-Mac-OS-X

and everything went well up until this very last bit. (Several warnings, but this was the only error.) I'm running on Mac-OS-X Lion (latest.)

Any help would be appreciated.

Thanks!

[chum]

P.S. All downloads -- c10t, boost, cmake, etc. -- were today & yesterday, so freshly installed.

[chum]

Bah! Sorry for the spamming -- a friend walked me through it. I was missing the steps where you

git submodule init
git submodule update

to get unc. I updated the building for OS-X wiki page. Hope that helps future Mac users.
