How to add compiler flags in VSCode

tisch — Wed, 08 Apr 2026 11:43:17 GMT

Hi,

how can I add compiler flags to VSCode?

I started a example from the NXP SDK with the MCUXpressor for VSCode plugin, which works good, but I need to change some compiler settings.

For example I don't need warnings into errors or need to change the optimization for compilation.

How can I change these settings?

Thank you.

Thank you for your post

The compiler Flags at MCUXpresso extension for VSCode could be edited in the CMakeLists.txt file that is located in your Project Files

For examples if you are using armgcc you need to use

mcux_add_armgcc_configuration(

CC "-O0"

)

Let me know if this information helps
