Hello!
I was struggling a bit to make it work, but if you're interested in make it work directly into pure data in m1 thank to chat gtp I could make it work compiling it directly with the terminal:

here is the code

`gen.name = gen_exported

change this to match the name of the external you would like to generate

(do not add a ~ suffix to the name here)

lib.name = OSCsimone

Don't forget to edit gen_buffer.h if your gen~ object references buffers in max.

genext.version = 0.7.0

$(lib.name)~.class.sources = gen_ext.cpp _ext.cpp ./gen/gen_dsp/genlib.cpp
cflags = -I ./gen -I./gen/gen_dsp -DGEN_EXT_VERSION=$(genext.version) -DPD_EXT_NAME=$(lib.name) -DGEN_EXPORTED_NAME=$(gen.name) -DGEN_EXPORTED_HEADER="$(gen.name).h" -DGEN_EXPORTED_CPP="$(gen.name).cpp"
suppress-wunused = yes

define forDarwin
ARCHFLAGS = -arch arm64 -arch x86_64
cflags += $(ARCHFLAGS) -DMSP_ON_CLANG -DGENLIB_USE_FLOAT32 -mmacosx-version-min=10.9
endef

define forLinux
$(lib.name)~.class.sources += ./gen/gen_dsp/json.c ./gen/gen_dsp/json_builder.c
endef

datafiles =

datafiles and datadirs:

All extra files you want to include in binary distributions of the

library: abstractions and help patches, example patches, meta patch, readme

and license texts, manuals, sound files, etcetera. Use 'datafiles' for all

files that should go into your lib rootdir and 'datadirs' for complete

directories you want to copy from source to distribution.

include ./pd-lib-builder/Makefile.pdlibbuilder`
