Eclipse setup for local build

Getting Started
1

I have been following along with the documentation for setting up a local build environment with debugging and everything has been going pretty smoothly so far. I can compile and load via DFU, I even have my J-Link working with SWD. The issue I have is when removing the C compilers -Os switch as the documents state. I am only compiling a very small blinky.cpp program to blink an LED but it seems that even so removing this option causes an error that appears to be related to the size of the compiled program not fitting in APP_FLASH.

Specifically, when i remove -Os from CFLAGS in firmware/build/arm-tools.mk i get this error:

You wonā€™t be able to build modular system parts with optimization disabled.

You should only disable optimization for a monolithic debug build (MODULAR=N DEBUG=Y). Thereā€™s really no reason to disable optimizations unless you are using the source debugger, anyway. With a MODULAR=N build thereā€™s only one gigantic part so thereā€™s room with optimizations disabled.

I guess that is the actual issue that I should have realized. I thought I was building for a monolithic build but I guess that error reporting a size for the ā€œAPP_FLASHā€ wouldnā€™t make sense then.

When I go to properties/C++Build/Environment I do have MAKEOPTS set to :
MODULAR=n DEBUG_BUILD=y USE_SWD_JTAG=y program-dfu

So I guess then the question becomes what i need to do to set this to make a monolithic project. I do want to be able to set breakpoints in my code.

I canā€™t see your make command and where you run it from, but if you donā€™t want a modular build you should not build from the modules directory but from main

Thank you both! I feel sheepish but I believe this solves this particular issue. looking through it more apparently clean project is setup to compile in the module directory and not main. I had been using clean project because build project was telling me that ā€œNothing to be done for ā€˜allā€™.ā€ Iā€™ll have to go hunt down why that is.
