How use other toolchain? (Read 2122 times)

	Hi, Somehow another avr-gcc toolchain is not used. I select my newer toolchain as always in AS7> Properties > Advanced, add the flags as always and notice when using new keywords that they are not known. In projects without vMicro plugin this works. With vMicro unfortunately not. Or does this have to be made known somewhere else? Is vMicro not interested in the AS7> Properties > Advanced setting? Thanks.

	Hi Because Visual Micro is Arduino compatible we use the same build system and configuration as the Arduino IDE. Toolchains and packages are installed via the Board Manager in Visual Micro or Arduino IDE. Visual Micro only uses the Atmel IDE for code edit, intellisense and hardware debug. The build system is unrelated therefore the atmel project properties have no effect. Please see Board Manager in our docs for some initial reading. The Board manager does provide a list of auto-discovered board packages (toolchains) but there are thousands more on the web. Any guide for the Arduino IDE works for Visual Micro. https://www.visualmicro.com/page/User-Guide.aspx?doc=index Does this help?

	Hi, I think we have misunderstood each other. I don't want to change the board but work with a current avr-gcc toolchain. And not only with the naked AS7 but also with vMicro. Does vMicro install files to C:\Users\Worker\AppData\Local\Arduino15 ? I do not have an installed Arduino IDE. Anyway, this made me think that vMicro could use this path and I put for the "Nano Every" in the folder C:\Users\...\AppData\Local\Arduino15\packages\arduino\hardware\megaavr\1.8.7\ added a customized platform.local.txt. This is now used by vMicro and I am back up to date. For standard Uno & Co this would be: C:\Users\...\AppData\Local\Arduino15\packages\arduino\hardware\avr\1.8.3. If you have a current avr-gcc toolchain write the following lines in a platform.local.txt for example Code compiler.path=C:\avrToolchain\avr-gcc-11.1.0_mingw32_binutils2.36.1/bin/ compiler.cpp.flags=-c -g -Os {compiler.warning_flags} -std=gnu++20 -fno-exceptions -fpermissive -ffunction-sections -fdata-sections -fno-threadsafe-statics -Wno-error=narrowing -MMD -flto -Wno-volatile compiler.cpp.extra_flags=-fno-sized-deallocation -Wall

	Okay I see thanks. Makes sense, you can also use a board.txt in the local project folder for testing this type of thing. It does similar to platform/board.local but overrides all. By default new board packages are installed into C:\Users\[name]\AppData\Local\Arduino15 but that can be changed if required. Am I right in believing that you have found the solution that you needed?
