How do I compile the latest PicoMite?

I have been compiling previous versions of the PicoMite software but with the current (B7) beta, I get all sorts of errors. How can I compile the latest beta?

Works for me. I can’t tell you what is wrong because I don’t know your build environment and you did not give examples of the error messages. I have a build script that I use under Raspberry Pi OS on a Pi5. The method is reasonably simple after installing the prerequisite products.

Unzip github archive in a directory
Move to the directory
Edit CMakeLists.txt to set variant (PICO,WEB,PICORP2350,WEBRP3250)
Delete build directory if it exists
Create a build directory
Change to build directory
Enter the command “cmake ..” or “cmake .. -DPICO_SDK_PATH=”
Then enter the command “make -j8”
If all goes well you will find “PicoMite.uf2” in the build directory.

    echo ==== PICO ====  
    sed -i 's/^set(COMPILE/#set(COMPILE/' CMakeLists.txt
    sed -i 's/#set(COMPILE .*)/set(COMPILE PICO)/' CMakeLists.txt
    BUILDDIR=build_picomite_pico1
    rm -rf $BUILDDIR
    mkdir $BUILDDIR; cd $BUILDDIR; cmake .. -DPICO_SDK_PATH=$SDK; make -j8;
    cp PicoMite.uf2 ../uf2/picomite_v${VER}${REV}\_pico1.uf2
    cd ..; #rm -rf $BUILDDIR

Here are the first errors:

Most likely you did not update CMakeLists.txt.
You must change

#set(COMPILE VGA)

to

set(COMPILE ????)

Where ??? is one of PICO, WEB, PICORP2350, WEBRP2350
Please note that “#” at the beginning of the line must also be removed.
