Hi,

I've been trying to compile using the STM32duino boards but the compile times are very long. It seems to re-compile bits that don't need re-compiling every time i try to build the program, here is the full build log attached:

Please follow the guide above and switch on both options, switch off high speed build then submit the output so that we have a clean simple picture.

I doubt the high speed build is causing the issue but when off we get a simpler build output. The issue will either be library or code related.

I think that yesterday I mentioned your builds are slow due to virus checker and recommended some tests but you haven't given feedback about that.

I have emailed 3 build logs, 1 build is the first initial build and the next 2 after afterwards with the antivirius enabled and disabled

Yep those builds were with high speed build switched off, and i will email through a release build.

Ok i have just emailed you a release build log, i'm compiling it with arduino ide now. it looks like it takes around 2-3 minutes to compile

I see same warnings in both your Arduino and VMicro outputs. Which warning are you referring too?

Yep that is in the vMicro output.

Because the compile works and it is also slow in the arduino ide I think that proves we are doing the right things. Therefore I suggest your questions be directed either at the stm tool chain provider or the library provider if a library is causing the issue.

I can say that the stm does produce dynamic files at the start of the build which requires many files to be compiled. However it's probably 10 or 15 seconds on our pc's and on my laptop. Therefore I think you also have a slow disk or something else interering. If not virus checker what about anti-malware software. I suggest looking at task manager to see if you can see the cause.

I suggest you post output from the arduino ide when posting build outputs on those sites. It will keep the conversation simpler. If you must post vm output then switch off debugging so the build properties are simpler/cleaner for other people to comment on.

Visual Micro has cached your code, the issue seems to be related to your pc. 

Here are some simple stats. Empty new project.

1st compile

Program Testme3 size: 5,132 bytes (used 31% of a 16,384 byte maximum) (76.86 secs)
Minimum Memory Usage: 428 bytes (10% of a 4096 byte maximum)
 
2nd compile (or after clicking build>clean solution)

Program Testme3 size: 5,132 bytes (used 31% of a 16,384 byte maximum) (4.68 secs)
Minimum Memory Usage: 428 bytes (10% of a 4096 byte maximum)

Weirdly it's not placing the object files anywhere when compiling the core?

g++ stuff -I"" -I"" aries\SrcWrapper\src\HAL\stm32yyxx_hal_dma.c" -o "nul"

It just has "nul"
