Hi,
I was pleased to learn about the support for the Renesas CCRX compiler since version 4.1 but I am still encountering difficulties setting it up.
My crosstoolchain file defines the compiler path and other stuff
...
SET(CMAKE_C_COMPILER "${CCRX_ROOT}/bin/ccrx.exe")
...
The configure step failed with the following error. The CCRX compiler does not seem to be detected. Why ? Should I need specific definition to hepl CMake to detect the compiler ?
[cmake] Not searching for unused variables given on the command line.

[cmake] It fails with the following output:
[cmake]

[cmake]
I tried forcing the compiler with :
...
SET(CMAKE_C_COMPILER "${CCRX_ROOT}/bin/ccrx.exe")
SET(CMAKE_C_COMPILER_ID CCRX)
SET(CMAKE_C_COMPILER_ID_RUN TRUE)
SET(CMAKE_C_COMPILER_FORCED TRUE)
...
But this implies adding in my crosstoolchain :
SET(CMAKE_C_COMPILE_OBJECT "${CMAKE_C_COMPILER} ${CMAKE_C_FLAGS} -output=obj=<OBJECT> <SOURCE>")
And in the CMakeLists.txt
set(CMAKE_INCLUDE_FLAG_C "-include=")
Could you tell me where I’m going wrong?
Any assistance is appreciated.
Regards,
Gildas
