[CMake] Compiling clang with cmake

[Nicolas Desprès]

Hi there,

Does someone have tried to compiled cmake master branch with clang?

I got this error:

Here my configuration option:

cmake ..
  -DCMAKE_INSTALL_PREFIX="$HOME/usr/stow/cmake"
  -DCTEST_TEST_CTEST=ON
  -DCTEST_TEST_CPACK=ON
  -DCPACK_BINARY_DEB=ON
  -DCPACK_BINARY_RPM=ON
  -DCPACK_BINARY_TBZ2=ON
  -DCPACK_SOURCE_ZIP=ON
  -DBUILD_DOCUMENTATION=ON
  -DBUILD_QtDialog=ON
  -DBUILD_CursesDialog=ON

I don't know if it is a cmake issues or a clang issues.

My version of clang:
clang version 2.8 (branches/release_28)
Target: i386-pc-linux-gnu
Thread model: posix

Installed with apt-get on an Ubuntu 10.10.

Cheers,
