ARM toolchain giving error on option '-rdynamic'

mzimmers

Hi all -

I'm trying to use CMake for a small ARM project. When it tries to build a test program, it fails, because of this:

arm-none-eabi-gcc: error: unrecognized command-line option '-rdynamic'

From my reading, it appears that the dynamic option is quite old, and wasn't to be used in Linux anyway, but my question is, where is this option being specified?

CMakeLists.txt:

add_executable(fw_iQPump_dev-MPI_6_1_109 ${SOURCES} )

include_directory(.)
include_directory(/home/mzimmers/wiced/sdk/WICED-Studio-6.6/43xxx_Wi-Fi/include)
include_directory(/home/mzimmers/wiced/sdk/WICED-Studio-6.6/43xxx_Wi-Fi/libraries/daemons/HTTP_server)
include_directory(/home/mzimmers/wiced/sdk/WICED-Studio-6.6/43xxx_Wi-Fi/libraries/protocols/HTTP_client)
include_directory(/home/mzimmers/wiced/sdk/WICED-Studio-6.6/43xxx_Wi-Fi/libraries/daemons/DNS_redirect)

set(SOURCES config_mode_dct.c 
           digitaloutput.c 
           i2d_app.c 
           iob.c 
           ioexpander.c 
           iwdg.c 
           MCP7940.c 
           random.c 
           RC4enc.c 
           schedule.c 
           SI2C.c 
           zuart.c
           )

Thanks for any suggestions...

@JoeCFD I saw that page. My toolchain is not old; I just downloaded it a couple weeks ago.

I tried creating a new project from scratch; same error. I do have this warning visible:

I'm not sure what this really means, though.
