I'm trying to get going with Eclipse/CDT and the STM32F4 Microprocessor libraries, and I've noticed a few funny things while setting up, but I'm guessing it's just due to a lack of understanding.
I have a project called "AbsMemAddress" setup, with a whole bunch of source files. It's basically just a test project.
main.c includes stm32f4xx.h which will include stm32f4xx_conf.h but only *IF* the USE_STDPERIPH_DRIVER symbol is defined.
Now, in Project -> Properties -> C/C++ Build -> Settings -> Cross GCC Compiler -> Symbols I placed this define in the Debug configuration section, but the software didn't seem to be picking up on this fact when I went to compile (the conf.h file definitions weren't being included. That was, until I thought "Maybe I was building for Release rather than Debug".
I checked and I wasn't, but I decided to place USE_STDPERIPH_DRIVER into the Release Symbols anyway.
After doing this, the build stopped throwing errors. I then deleted the define from the Release section, and it still worked. 
What's going on? Does the IDE only update the defined symbols on an irregular basis?
