The actual (compiler or linker error) should be printed somewhere above this.
here is the full log…
im not sure what the problem is
4.4.x cannot be compiled with the newest (clang 3.5.0-based) toolchain. You need to use the toolchain that it was released against, which is clang 3.3-based. Here’s the link to it for your convenience: http://cdn.unrealengine.com/qfe/v3_clang-3.3_ld-2.24_glibc-2.12.2.zip
thanks it works ! 
Cool! Have fun.
