General • Compiling TenserflowLite Micro library for Pico problems

Hello forum!

I am having problems with compiling the TenserflowLite Micro library for Pico. (github link: https://github.com/raspberrypi/pico-tflmicro)

I am on a windows 10 pc (using Visual Code Developer CMD prompt) and I have updated pico-sdk to latest. And I can compile pico-sdk, pico-examples, etc without problem and I have
been doing some development. Fun!

But when I try to compile the TenserflowLite Micro library for Pico I run into the following problems.

1) After the first step:
cmake -G "NMake Makefiles" ..
I get a warning about long paths, and I fixed that by adding set(CMAKE_OBJECT_PATH_MAX 500) to the cmake file.

2) On the second step: nmake I get the following error

Is there anyone here that managed to compile on windows? All help is appreciated.
Thanks in advance!
