Problems building sample Mac VST


Hi all,

Hoping someone can help me. I’m trying to build the latest build of Juce ( 1.38 ) as well as the latest Audio plugin framework ( 1.11 ) demo. I’ll confess that I’m a Mac nube. My configuration is:

Xcode 2.4
Intel Core Duo
OSX 10.4.8
PPMulator.vst (demo)
Cubase 4.0 (UB)
Tracktion 2 (demo)

I am able to build Juce in both debug and release mode by modifying the juce.xcconfig to:

ARCHS = ppc i386
SDKROOT = /Developer/SDKs/MacOSX10.4u.sdk
GCC_VERSION_ppc = 3.3
OTHER_LD_FLAGS_ppc = /Developer/SDKs/MacOSX10.3.9.sdk/usr/lib/gcc/darwin/3.3/libstdc++.a
SDKROOT_ppc = /Developer/SDKs/MacOSX10.3.9.sdk

as the 10.2 stuff is not on my machine.

I am also able to produce a release build of JuceVST.vst but not the debug build. I get the following error:

Linking /Users/JP/Library/Audio/Plug-Ins/VST/

ld: …/…/…/…/juce/bin/libjucedebug.a(juce_String.o) illegal reference for -dynamic code (section difference reference from section (__TEXT,__eh_frame) relocation entry (46) to symbol: ___isfinite defined in dylib: /Developer/SDKs/MacOSX10.3.9.sdk/usr/lib/libSystem.dylib)

In all cases, I place a copy of the release build of JuceVST in the /Library/Audio/Plug-ins/VST folder but am unable to get the plugin to load.

In Cubase, I am able to load the plugins which come with the VST SDK (which I build separately), but not able to load JuceVST or PPMulator. There is nothing of use in the console log.

In Tracktion, I am not able to load JuceVST or any of the VST SDK plugins. I am able to load PPMulator. In the console log it says:

searching in /Library/Audio/Plug-Ins/VST

ignoring plugin: again.vst

ignoring plugin: JuceVST.vst

VST: mda Ambience
VST: mda AutoPan
VST: mda Bandisto
VST: mda BeatBox

Sorry for the long post, but wanted to provide as much info as possible. If anyone can provide any assistance or ideas I’d appreciate it!



see if this thread helps…


Adding your fix to the juce_MathsFunctions corrected the debug build problem, but I’m still unable to load the plug in Cubase 4 or Tracktion 2 demo.

Any thoughts?


Could be a ppc/intel mismatch of some kind, I guess…


What are the conditions under which Tracktion ignores plugins (in the logs)?

Are you able to build the demo and get it to run on intel?


A PPC-only application won’t be able to use an intel-only plugin, and vice-versa. Not sure if a ppc app can use a UB plugin, though I’d have thought it’d be ok.
