I managed to fully build this for Apple Silicon - Works like a charm

[dmitridb]

Hello;

I'm noticing the binaries last released in 2023 were just X64, so I went and took the time to port it to apple silicon - I'll make a pull request if I can get a confirmation that this isn't already in the pipeline or something, any guidance on the process to do that?

Admittedly I just let claude do this lol. Here's the BUILD-LOG.md it generated in case anyone else wants to get this done and would like a starting point in the meantime

PortAudio was successfully installed.

On some systems (e.g. Linux) you should run 'ldconfig' now
to make the shared object available. You may also need to
modify your LD_LIBRARY_PATH environment variable to include
the directory /usr/local/lib

/Applications/Xcode.app/Contents/Developer/usr/bin/make install-recursive
if test -n "" ; then for dir in ""; do /Applications/Xcode.app/Contents/Developer/usr/bin/make -C $dir install; done ; fi

[3] CDP build OK Sun 28 Jun 2026 18:44:20 CST: make exit=0, 0 errors, native arm64, no source patches.

  /usr/local/lib/libportaudio.a
  /usr/local/lib/pkgconfig/portaudio-2.0.pc
  /usr/local/include/portaudio.h
• CDP8 source+build: ~/cdp-build/CDP8 (build/, NewRelease/)
• CDP binaries (arm64, 220): ~/cdp/_cdprogs
• Renoise tool installed: ~/Library/Preferences/Renoise/V3.5.4/Scripts/Tools/com.afta8.CdpInterface.xrnx
• Patched installer kept: ~/cdp-build/com.afta8.CdpInterface.xrnx

CONFIG FLAGS:

• portaudio: ./configure --enable-shared=no --enable-mac-universal=no (per dev/externals/paprogs/pamacbuild.txt)
• CDP cmake: cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_POLICY_VERSION_MINIMUM=3.5

PATCHES:

1. portaudio Makefile: removed all -Werror (clang 21 -Wimplicit-const-int-float-conversion in
   src/common/pa_converters.c, *src * 0x7FFFFFFF). Backup: paprogs/portaudio/Makefile.orig
2. CDP8 source: NONE (clean on clang 21; repo Sept-2025 revision).
3. Tool manifest.xml: ApiVersion 5 -> 6. Backup: CdpInterface_patched/manifest.xml.orig

TOOL PATH CONFIGURED: CDP dir -> ~/cdp/_cdprogs (tool first-run file selector)
VERIFICATION [9]: sample processed through CDP inside Renoise returned transformed audio. CONFIRMED.

ROLLBACK (in this order):

1. Remove tool: rm -rf ~/Library/Preferences/Renoise/V3.5.4/Scripts/Tools/com.afta8.CdpInterface.xrnx
2. Uninstall portaudio (needs build dir, so BEFORE step 4):
   cd ~/cdp-build/CDP8/dev/externals/paprogs/portaudio && sudo make uninstall
   (or: sudo rm -f /usr/local/lib/libportaudio.a /usr/local/lib/pkgconfig/portaudio-2.0.pc /usr/local/include/portaudio.h)
3. Remove binaries: rm -rf ~/cdp
4. Remove build tree: rm -rf ~/cdp-build
