Blink project for Generic STM32F1 Series wont compile without 'deep search' enabled

I am trying to compile a very simple 'blink' program with a STM32 target.  The program compiles OK in VS/VM with 'deep library search' enabled, but fails if it is not enabled.  The same program compiles fine in the Arduino IDE.

I have attached a zip file containing

200801_STM32_Compile_ArduinoIDE.txt - verbose compile in Arduino IDE
200801_STM32_Compile_vMicro_NoDeepLibrarySearch.txt - verbose in VS/VM w/o 'deep search' enabled
200801_STM32_Compile_vMicro_WithDeepLibrarySearch.txt - verbose in VS/VM with 'deep search' enabled

While the 'deep search' option does allow compiles to finish successfully, it takes MUCH longer - 10s of seconds with deep search enabled, vs 4-5 sec without.

Any thoughts?

TIA,

Frank

That is the way that core is designed

Tim,

Thanks for clearing that up for me!

So, does the Arduino IDE also always do a deep search?  Or did I have that option enabled and didn't know it?

Frank

Hi

Yes Arduino IDE always deep searches. 

The problem is that the STM32 uses a pre build rule to create a .cpp file with a list of all the libraries it needs. It relies on the fact that deep search will then scan the .cpp

That particicular core you are using is a single core for many different STM architectures and as such provides a lot of the differences via libraries. Therefore when you build it automatically includes all the libraries it needs.

An alternative if you are using only one architecture is to add to the .ino code an "#include" for one ".h" from each of the libraries that are automatically included when deep search is enbled. Then switch off deep search.
