IPlug and xcode

[cc_]

I spent a while getting IPlug/wdl compiled under XCode 3.1 (on OSX 10.5), mostly moving files around, finding missing files, making projects etc... if anyone's interested I zipped up the resulting files:

http://burbleland.com/tmp/iplug_xcode_20090316.zip

There are Xcode projects in lice , IPlug and IPlugExample - just add the 2 vstsdk files, build the projects and you should have a plugin. More details of what I had to change in the README.txt file. This is my first go with XCode, so I may have done something wrong, but the example plugins both seem to run (vst and au), so that's a good sign...

One thing I didn't figure out: when I was compiling IPlugVST.cpp it complained about the deprecated things not being in the AEffect structure, but when I preprocessed the file manually (still in XCode) they were there. Replacing IPlugVST.cpp with the manually generated preprocessed version got it to compile. Any ideas how to fix this?

hey,

thanks for your xcode projects. unfortunately i can't get them to build. But i am confused by your instructions and so i could have done something wrong. I am using the latest xcode on 10.5.6 on an intel mac

1 - open wdl/lice/lice.xcodeproj and build the target lice (this builds
build/Release/licelib-a

should I build the release or debug version? I built the release

2- open wdl/IPlug/IPlug.xcodeproj and build the target IPlug (this
builds build/Debug/libIPlug.a)

i get an error:

/Developer/Examples/CoreAudio/PublicUtility/CAStreamBasicDescription.h: At global scope:
/Developer/Examples/CoreAudio/PublicUtility/CAStreamBasicDescription.h:61: error: expected identifier before '(' token
/Developer/Examples/CoreAudio/PublicUtility/CAStreamBasicDescription.h:61: error: expected `}' before '(' token
/Developer/Examples/CoreAudio/PublicUtility/CAStreamBasicDescription.h:61: error: expected `)' before '|' token
/Developer/Examples/CoreAudio/PublicUtility/CAStreamBasicDescription.h:61: error: expected declaration before '}' token

it points to here

// define Leopard specific symbols for backward compatibility if applicable
#if COREAUDIOTYPES_VERSION < 1050
typedef Float32 AudioSampleType;
enum { kAudioFormatFlagsCanonical = kAudioFormatFlagIsFloat | kAudioFormatFlagsNativeEndian | kAudioFormatFlagIsPacked };
#endif

I can compile it if i comment out the above define but...

3 - open wdl/IPlugExample/IPlugExample.xcodeproj and build either IPlugExample (which
builds build/Debug/IPlugExample.vst) or IPlugExampleAU (which builds
build/Debug/IPlugExample.component)

doesn't build:

any ideas?

when I was compiling IPlugVST.cpp it complained about the deprecated things not being in the AEffect structure, but when I preprocessed the file manually (still in XCode) they were there.

I notice this in affect.h:

#if __ppc__
#ifndef VST_FORCE_DEPRECATED
#define VST_FORCE_DEPRECATED 0
#endif
#endif

I have no idea why they've done that, but my guess is that if you're compiling a universal binary, the ppc build is throwing the warnings/errors. You could try just commenting that out.

Not sure about the first few things (sounds like you worked around them though).

I did get these once though:

That was when the build target was set to 10.4 (instead of 10.5) in IPlug and/or IPlugExample.

Cheers, I'll give it a go later...

excellent both compiled now!

I finally got round to trying this, and it worked.
Thanks.
