Missing dependency on GNU/Linux?

Hi, I am trying to compile the developer edition, but I am having the following error:

And equivalent to that repeated times. My configure is:

cmake .. \
-DCMAKE_BUILD_TYPE=Release                                      \
-DCMAKE_C_COMPILER=/usr/bin/gcc-5                           \
-DCMAKE_CXX_COMPILER=/usr/bin/g++-5                 \

-DENABLE_EIGEN=OFF                                              \
-DEIGEN_INCLUDE_DIR="~/src/eigen"                               \

#decomment this to have it verbose
# make VERBOSE=1 -j4
make -j4
# sudo make install

I am using GCC-5 (If I am able to compile the basic I will try with CUDA)

Many thanks in advance

Hi, I'm afraid that this is a weakness of extra C++11 operator support in ViennaCL: rsqrt(), exp10(), and sign() (possibly also trunc()) are incorrectly used. I'll delete the respective operators in a day or two (I'm currently on travel).

A workaround is to compile only with C++03 with the flag -std=c++03.

Thanks a lot, I will close this. Regards

I just pushed a fix for the compilation issues in C++11 mode. Thanks for bringing this to my attention!
