Link error: Symbol __user_perthread_libspace multiply defined

[toyowata]

Description

I got link error below when I build mbed-os-example-blinky project for any target.

Error: Symbol __user_perthread_libspace multiply defined (by /build/mbed-os.lib/rtos/TARGET_CORTEX/rtx5/RTX/Source/rtx_lib.GR_LYCHEE.o and /build/mbed-os.lib/rtos/TARGET_CORTEX/mbed_boot.GR_LYCHEE.o).
Error: Not enough information to list the image map.
Info: Unable to download. Fix the reported errors...

[Steps to reproduce]

• Import mbed-os-example-blinky program
• Set target to Mbed OS 5 support platform (e.g. Renesas GR-LYCHEE, NXP K64F etc)
• Compile the program

[Other notes]

• This link error cannot be shown in command line build by Mbed-CLI

I got same issue for L476RG....
Error: Symbol __user_perthread_libspace multiply defined (by /build/mbed-os.lib/rtos/TARGET_CORTEX/rtx5/RTX/Source/rtx_lib.NUCLEO_L476RG.o and /build/mbed-os.lib/rtos/TARGET_CORTEX/mbed_boot.NUCLEO_L476RG.o).

I confirmed the error with NUCLEO_F746ZG and only ARM toolchain with 5.9.2 label.

[DEBUG] Errors: Error: L6200E: Symbol __user_perthread_libspace multiply defined (by BUILD/tests/NUCLEO_F746ZG/ARM/rtos/TARGET_CORTEX/rtx5/RTX/Source/rtx_lib.o and BUILD/tests/NUCLEO_F746ZG/ARM/rtos/TARGET_CORTEX/mbed_boot.o).

Hi again
I have compared my local profile with the one in tools/profiles,
and it seems that -D_RTE_ was missing.
I can't explain what it is, but it solves my compilation issue...

Thanks @jeromecoutant I'll look into it.

[0xc0170]

@jeromecoutant RTE is defined for 5.9.2 . is that causing a problem?

cc @ARMmbed/mbed-os-core

[0xc0170]

I suspect this is the one that is causing a problem #6973. I'll check why rtx lib does not see the no multithreaded macro and why this was not seen in our CI previously

[0xc0170]

@theotherjimmy I referenced 7447 but that one is about own profile. This issue is in the online compiler. Can you check that profiles were updated there? RTE symbol defined? (until 5.9.3 contains proper fix for this)

[theotherjimmy]

See #7449

[theotherjimmy]

We need to backport that patch into 5.9.2 to fix the problem in the online compiler.
