Hi,
I'm looking for guidance about how to use the S32K toolchain.
Context
I'm trying to use the S32K Linux (Ubuntu 16) arm-none-eabi build tools to compile my project.
I'm using CMake and Make to do so.
Currently, the build system fails at the "check for working C compiler" step. The exact error message is:
cc1: fatal error: lib_c99.prefix: No such file or directory
Of course, this file exists in my build_tools directory:
$ find /usr/local/build_tools/arm32_ewl2 | grep lib_c99
/usr/local/build_tools/arm32_ewl2/EWL_C/include/lib_c99.prefix
While the CMake toolchain file could be the cause of this problem, my compiler flags seem identical to the one used when compiling the project with the S32 DS IDE:
usr/local/build_tools/gcc-6.3-arm32-eabi/bin/arm-none-eabi-gcc -c -fmessage-length=0 -ffunction-sections -fdata-sections -mcpu=cortex-m4 -mthumb -specs=ewl_c9x_noio.specs --sysroot="/usr/local/build_tools/arm32_ewl2" -mfloat-abi=hard -mfpu=fpv4-sp-d16 -fdata-sections -ffunction-sections -o CMakeFiles/cmTC_ee422.dir/testCCompiler.c.obj -c /root/nBMSMv2_Tools/myproject/build/CMakeFiles/CMakeTmp/testCCompiler.c
I think the problem might reside in my environment setup.
Here's my build_tools tree:
/usr/local/build_tools/
|-- arm32_ewl2 # <-------- SYSROOT
| |-- Build_Tag.txt
| |-- Doxyfile
| |-- EWL_C
| |-- EWL_C++
| |-- EWL_ReleaseNotes
| |-- EWL_Runtime
| |-- lib
| `-- makefile
`-- gcc-6.3-arm32-eabi
|-- arm-none-eabi
|-- bin
|-- include
|-- lib
|-- libexec
|-- linux_support
|-- patches_applied
`-- share
Question
Why can't arm-none-eabi-gcc find the lib_c99.prefix file?
If all the compilation flags are identical to the one used by the IDE, what did I miss? Is this a question of environment variables?
Thanks.
