[SOLVED] Use of precompiled library

[blue-man]

I want to ask if it is possible to use an precompiled library?

Here is an example for it: download/file.php?id=176&sid=bd03c2e776 ... cc98b0a32d

What i have found is the description here: https://arduino.github.io/arduino-cli/l ... ification/ with

precompiled - (available from Arduino IDE 1.8.6/arduino-builder 1.4.0) (optional) set to true to allow the use of .a (archive) and .so (shared object) files. The .a/.so file must be located at src/{build.mcu} where {build.mcu} is the architecture name of the target the file was compiled for. Ex: cortex-m3 for the Arduino DUE. The static library should be linked as an ldflag.

So i added in .../arduino15/packages/STM32/hardware/stm32/1.8.0/libraries/SrcWrapper/library.properties

Code: Select all

precompiled=true

and .../arduino15/packages/STM32/hardware/stm32/1.8.0/libraries/SrcWrapper/src/sc_math.a

But it still errors out with

Code: Select all

APM-Test.ino.cpp:(.text.loop+0xbc): undefined reference to `sc_math_sin(float)'

Any ideas?

As explained in the library specification, you have to put it in the src/{build.mcu} not in src/ where {build.mcu} is the architecture name of the target the file was compiled for.

Not that the core will not support the APM32 as only STM32 is supported.
Instead of modifying the core you should create your own library with the lib and a dedicated include.

What will be the path "src/{build.mcu}" ?
Is it the tmp path for compilation?

Of course this is not an STM32 - this is just an experiment, to proof if there is really an FPU that can be used.

The manufacturer tries to hide his "secrets" in a precompiled library.
This is part of an SDK.

It's the same result with .../arduino15/packages/STM32/hardware/stm32/1.8.0/libraries/SrcWrapper/src/stm32/sc_math.a

[fpiSTM]

stm32 is not the {build.mcu}... cortex-m3 is

So:

Code: Select all

src/cortex-m3/sc_math.a

[blue-man]

stm32 is not the {build.mcu}... cortex-m3 is

So:

Code: Select all

src/cortex-m3/sc_math.a

Yes - Thanks a lot!

Now the compiled library is used.

But it seems to lead to much incompatibility problems.

Code: Select all

You should create a dedicated library because I guess the pre compiled lib replace all other objects of the SrcWrapper library

[blue-man]

Of course.

But now this is not interesting any more. viewtopic.php?p=2710#p2710
