nRF5 SDK Example build error

Question

I've installed the Segger Embedded Studio and Nordic SDK (C:\Nordic
RF5_SDK_15.1.0) following the tutorial video on the nRF5 webpage. 
 Right out of the box, trying to Build/Run the example: C:\Nordic
RF5_SDK_15.1.0\examples\ble_peripheral\ble_app_hrs\pca10040\s132\ses\ble_app_hrs_pca10040_s132.emProject 
 I get the following error: Linking ble_app_hrs_pca10040_s132.elf 1 Error: 
 cannot find ../../../../../../external/micro-ecc/nrf52hf_armgcc/armgcc/micro_ecc_lib_nrf52.a: No such file or directory 
 I'm suspecting that I've missed configuring something, but retracing my steps I don't see what. 
 Any thoughts? 
 Jim

Hi Jared, 
 I found the problem... first, I got rid of the MinGW GCC and installed gcc-arm-none-eabi-7-2018-q2-update. I had already renamed mingw32-make.exe to be "make.exe" and all paths were "correct"... Except for the fact that in the ..toolchain\gcc\makefile.windows file, I had done a cut/paste of 
 GNU_INSTALL_ROOT := C:/Program Files (x86)/GNU Tools Arm Embedded/7 2018-q2-update/bin/ GNU_VERSION := 7.3.1 GNU_PREFIX := arm-none-eabi 
 which put "\" characters in the path, rather than "/"!!!!!!!!! Unbelievable we're still stuck with tools that don't conform to the conventions of the OS that they are running on! 
 Anyway, I'm now able to build/flash/run examples on the nRF52-DK board. 
 Thanks for your generous and responsive help! 
 Jim
