Link Error in Elektron-SDK-1.4

epfeuffer

All of these appear to be internal to the Elektron-SDK. Not sure why this would ship when it doesn't compile out of the box. Anyone have any idea before i start debugging Elektron code?

These errors appear to be related to the Googletest macros not getting recognized by the linker. Is this build using the default version of Googletest? ESDK is not built with C++11, and Googletest has some weird interactions that has prompted them to create a non-backwards compatible version that supports only C++11 on.

In addition, if you don't need the unit test tools, they can be removed from the build by setting the option -DBUILD_UNIT_TESTS=OFF when generating the build files with cmake.
