Building helloworld.elf #249
Description
Hey! I was trying to build an EbbRT dependent application, so I followed the instructions given in https://github.com/SESA/EbbRT/wiki/Build-Tutorial-Notes. While building the helloworld application, I got this error:
-- The C compiler identification is unknown
-- The CXX compiler identification is unknown
System is unknown to cmake, create:
Platform/EbbRT to use this system, please send your config file to cmake@www.cmake.org so it can be added to cmake
Your CMakeCache.txt file was copied to CopyOfCMakeCache.txt. Please send that file to cmake@www.cmake.org.
CMake Error at CMakeLists.txt:2 (project):
The CMAKE_C_COMPILER:
/home/user/ebbrt-sysroot/ebbrt/usr/bin/x86_64-pc-ebbrt-gcc
is not a full path to an existing compiler tool.
Tell CMake where to find the compiler by setting either the environment
variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
the compiler, or to the compiler name if it is in the PATH.
CMake Error at CMakeLists.txt:2 (project):
The CMAKE_CXX_COMPILER:
/home/user/ebbrt-sysroot/ebbrt/usr/bin/x86_64-pc-ebbrt-g++
is not a full path to an existing compiler tool.
Tell CMake where to find the compiler by setting either the environment
variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path
to the compiler, or to the compiler name if it is in the PATH.
-- Configuring incomplete, errors occurred!
If I understood it correctly this means that cmake is trying to find a cross compiler binary "x86_64-pc-ebbrt-gxx" as specified by ebbrt.cmake. However, during the build, no such file was created.
Any pointers on how to solve this would be highly appreciated.
