`make` command fails

[Miraj98]

According the README I was able to execute these commands successfully

git clone git://github.com/Ebiroll/qemu-xtensa-esp32
mkdir qemu_esp32
cd qemu_esp32
../qemu-xtensa-esp32/configure --disable-werror --prefix=`pwd`/root --target-list=xtensa-softmmu,xtensaeb-softmmu

But on trying to run make it fails the following error trace

22 warnings generated.

Not sure what's the issue. Any help is appreciated

[Ebiroll]

Try to add #include <stddef.h> in the file that has problem compiling

[Miraj98]

Not sure what file that would be. I added #include <stddef.h> in qemu-xtensa-esp32/hw/xtensa/MemoryMapped.cpp but still didn't seem to work

[jpitkanen18]

You need to install Device Tree Compiler (DTC) on macOS with homebrew installed run brew install dct

[hughlv]

I am facing the exactly same issues when trying 'make' on macOS Big Sur.

Basically following errors:

1. error: expected unqualified-id -- from MappedMemory.cpp
2. /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/v1/iterator:562:13: error: unknown type name 'ptrdiff_t'
3. /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/v1/iterator:989:54: error: template parameter missing a default argument class _Traits = char_traits<_CharT>, class _Distance = ptrdiff_t>

All looked like lib compatibility issues. I've followed the suggestion from @Ebiroll and added 'include <stddef.h>' as the first line of MappedMemory.cpp but got no luck. Still the same errors.

Any clues to solve these issues? Thanks.

@jpitkanen18 Tried this but did not work. Getting the same error. Also there is a typo. If I am not wrong it should be dtc and not dct

[fanzhiri]

I encountered this error and I solved it . rename the file : qemu-xtensa-esp32/version @Miraj98 for you : mv /Users/miraj/qemu-xtensa-esp32/version /Users/miraj/qemu-xtensa-esp32/py_version

[mbbender]

I had the same issue and @fanzhiri workaround helped me make the project. On mac. Did not install DTC.

I installed the compiler (dtc indeed) but ALSO renamed the version file to version.txt and forgot about it. My bad haha
