Conditional compiling depending on platform type?

04 Nov 2014


is there a solution for conditional compiling, depending on the chosen platform type?

I'm developing for LPC1114, but for easier testing I'm using normal mbed device. So I have to change platform type and many defines to match the appropriate processor type.

Sure I can use #define in combination with #ifdef / #else / #ifndef, but I'm asking if there might already be a directive to have the compiler decide which part of code has to be taken automatically (like MBED_BUILD_TIMESTAMP for example)?

You should be able to use


These are basically the directory names for target specific code in the mbed SDK for example the code specific to LPC11XX lives in libraries/mbed/targets/cmsis/TARGET_NXP/TARGET_LPC11XX_11CXX/TARGET_LPC11XX.

All of the capitalised directories in that path are passed to the compiler as defines, so you could have #ifdefs for


Which you could choose depending on how specific your code is.

Hello Stephen,

thanks for the fast reply - I'll test this at once, that's exactly what I was looking for!

Best regards,
