Compiling Error

Error: "/tmp/vx6V3T", line 124 (column 3): Warning: L6312W: Empty Execution region description for region RW_IRAM1 Error: Symbol user_perthread_libspace multiply defined (by /build/mbed-os.lib/rtos/TARGET_CORTEX/rtx5/RTX/Source/rtx_lib.K64F.o and /build/mbed-os.lib/rtos/TARGET_CORTEX/mbed_boot.K64F.o). Error: Not enough information to list the image map.

Hello, I am new in Mbed, I was trying some tutorial. So added a library, and compile it first before even editing the code in main.cpp. it gives me above error.

How would I fix that error and what is the reason behind this error?

Please let me know,

Hello there,

This has been an issue for programs using Mbed OS 5.9.2. There is a github issue that has been raised:


If you are using the online compiler:

Under the Compile button, navigate to Compile Macros and add _RTE_ in the text box. Then try recompiling.

I was able to successfully compile the program through these steps. Hope this helps!

Hi there,

I have tried this solution but it is not working. The error still persists, the link to Github just says to do the same thing.

Any other ideas? Thanks
