如何将VAMP插件编译为iOS ARMV7

伦敦皇后大学玛丽大学的 VAMP插件是一个惊人的BSD许可软件集合.所有这些插件都是 Sonic Visualizer软件的基础
A plug Sdk也可以使用构建插件.

您可以为OSX / Linux / Win32目标构建插件.

Queen Mart大学很好地解释了here插件架构以及如何为上面指定的不同平台构建.

Java版本,jVamp也可用.一个Python包装器也.

但是,如何为iOS平台构建？

所以,我尝试将Makefile移植到iOS.

首先我改变了文件

build/osx/Makefile.osx

通过这种方式：

CFLAGS := -O3 -ftree-vectorize -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -arch x86_64 -I../vamp-plugin-sdk -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/System/Library/Frameworks/Accelerate.framework/Frameworks/vecLib.framework/Headers/ -DUSE_PTHREADS

CXXFLAGS  := $(CFLAGS)

LDFLAGS   := -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -arch x86_64 -lqm-dsp ../vamp-plugin-sdk/libvamp-sdk.a -framework Accelerate -lpthread -exported_symbols_list=vamp-plugin.list -install_name qm-vamp-plugins.a

PLUGIN_EXT   := .a

include build/general/Makefile.inc

然后建立

macbookproloreto:qm-vamp-plugins loreto$make -f build/osx/Makefile.osx
cc -O3 -ftree-vectorize -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -arch x86_64 -I../vamp-plugin-sdk -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/System/Library/Frameworks/Accelerate.framework/Frameworks/vecLib.framework/Headers/ -DUSE_PTHREADS -I. -I../qm-dsp   -c -o g2cstubs.o g2cstubs.c
c++ -O3 -ftree-vectorize -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -arch x86_64 -I../vamp-plugin-sdk -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/System/Library/Frameworks/Accelerate.framework/Frameworks/vecLib.framework/Headers/ -DUSE_PTHREADS -I. -I../qm-dsp   -c -o plugins/AdaptiveSpectrogram.o plugins/AdaptiveSpectrogram.cpp

      architecture
#error Unsupported architecture
 ^**

这里的第一个问题是有一个不受支持的架构.

所以插件取决于我必须首先构建那个的SDK：

cd /Users/loreto/Projects/AUdio/VAMP/vamp-plugin-sdk
make -f build/Makefile.osx

由于我没有OGG/VORBIS库而没有LOGG库,因此发生了不同的错误.所以我稍微修改了Makefile.osx,删除了HOST_LIB标志中的这些依赖项.不过我还是要保留libsndfile：

HOST_LIBS       = ./libvamp-hostsdk.a -L../10.8/inst/lib -lsndfile -ldl

所以我能够在这里构建静态库：

macbookproloreto:vamp-plugin-sdk loreto$ls -l *.a
-rw-r--r--  1 loreto  staff  709840 17 Ott 23:56 libvamp-hostsdk.a
-rw-r--r--  1 loreto  staff  183720 17 Ott 23:56 libvamp-sdk.a

当然这些静态库的目标是arch x86_64,所以我需要添加armv7 arch：

ARCHFLAGS = -mmacosx-version-min=$(MINVERSION) -arch x86_64 -arch armv7

然后再清理并再次编译

macbookproloreto:vamp-plugin-sdk loreto$make -f build/Makefile.osx clean
macbookproloreto:vamp-plugin-sdk loreto$make -f build/Makefile.osx
c++ -mmacosx-version-min=10.8 -arch x86_64 -arch armv7 -O2 -Wall -I. -I../10.8/inst/include -fPIC   -c -o src/vamp-sdk/PluginAdapter.o src/vamp-sdk/PluginAdapter.cpp
In file included from src/vamp-sdk/PluginAdapter.cpp:37:

#include "arm/_types.h"
         ^
1 error generated.
make: *** [src/vamp-sdk/PluginAdapter.o] Error 1

未找到arm的类型定义！这里的问题是正确的道路是

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/include/arm/_types.h

好的,让我们再次在Makefile.osx中解决这个问题：

ARCHFLAGS = -mmacosx-version-min=$(MINVERSION) -arch armv7
CFLAGS          = $(ARCHFLAGS) -fPIC --sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -isystem /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/include/
CXXFLAGS        = $(ARCHFLAGS) -O2 -Wall -I. -fPIC
CPPFLAGS        ="-pipe -no-cpp-precomp -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/include/" -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk

然后制作静态目标：

make -f build/Makefile.osx sdkstatic

哇有效！我有一个适用于iOS的鞋面主机sdk .a！ (我想让我们说)

macbookproloreto:vamp-plugin-sdk loreto$ls -l *.a
-rw-r--r--  1 loreto  staff  301176 18 Ott 00:35 libvamp-hostsdk.a
-rw-r--r--  1 loreto  staff   76024 18 Ott 00:35 libvamp-sdk.a

好的,但是让我们检查otool,因为你永远不会知道：

macbookproloreto:vamp-plugin-sdk loreto$otool -hv libvamp-sdk.a
Archive : libvamp-sdk.a
libvamp-sdk.a(PluginAdapter.o):
Mach header
      magic cputype cpusubtype  caps    filetype ncmds sizeofcmds      flags
   MH_MAGIC     ARM         V7  0x00      OBJECT     4       1128 SUBSECTIONS_VIA_SYMBOLS
libvamp-sdk.a(RealTime.o):

      magic cputype cpusubtype  caps    filetype ncmds sizeofcmds      flags
   MH_MAGIC     ARM         V7  0x00      OBJECT     4       1060 SUBSECTIONS_VIA_SYMBOLS
libvamp-sdk.a(FFT.o):
Mach header
      magic cputype cpusubtype  caps    filetype ncmds sizeofcmds      flags
   MH_MAGIC     ARM         V7  0x00      OBJECT     4        584 SUBSECTIONS_VIA_SYMBOLS
libvamp-sdk.a(acsymbols.o):
Mach header
      magic cputype cpusubtype  caps    filetype ncmds sizeofcmds      flags
   MH_MAGIC     ARM         V7  0x00      OBJECT     3        500 SUBSECTIONS_VIA_SYMBOLS

好的,这就是armv7架构.

现在,再次回到插件sdk并更改

build/osx/Makefile.osx

如下：

CFLAGS := -arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/include/ -DUSE_PTHREADS

CXXFLAGS  := $(CFLAGS)

include build/general/Makefile.inc

好的,再回来做：

macbookproloreto:dsp loreto$make -f build/osx/Makefile.osx

繁荣！另一个问题：

/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/include/ -DUSE_PTHREADS -I.   -c -o dsp/wavelet/Wavelet.o dsp/wavelet/Wavelet.cpp
cc -arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/include/ -DUSE_PTHREADS -I.   -c -o hmm/hmm.o hmm/hmm.c
hmm/hmm.c:21:10: Fatal error: 'clapack.h' file not found
#include <clapack.h>            /* LAPACK for matrix inversion */
         ^
1 error generated.
make: *** [hmm/hmm.o] Error 1
macbookproloreto:dsp loreto$vi build/osx/Makefile.osx

找不到LAPACK.

但至于Apple Docs here,Apple自iOS4.0起就在Accelerate.frameworks中引入了LAPACK！

实际上clapack.h在这里：
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/System/Library/Frameworks/Accelerate.framework/Frameworks/vecLib.framework/Headers/clapack.h

所以让我们在../dsp/build/Makefile.osx中添加它

CFLAGS := -arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/include/ -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/System/Library/Frameworks/Accelerate.framework/Frameworks/vecLib.framework/Headers/ -DUSE_PTHREADS

现在让我们再来一次,但让我检查一下拱门：

macbookproloreto:dsp loreto$otool -hv libqm-dsp.a 
Archive : libqm-dsp.a
libqm-dsp.a(Pitch.o):
Mach header
      magic cputype cpusubtype  caps    filetype ncmds sizeofcmds      flags
   MH_MAGIC     ARM         V7  0x00      OBJECT     4        516 SUBSECTIONS_VIA_SYMBOLS
libqm-dsp.a(Chromagram.o):
Mach header

听起来不错！现在又回到了plugins文件夹中的一个级别

In file included from plugins/AdaptiveSpectrogram.cpp:15:
plugins/AdaptiveSpectrogram.h:22:10: Fatal error: 'dsp/transforms/FFT.h' file not found
#include <dsp/transforms/FFT.h>
         ^
1 error generated.

嗯,好吧,dsp /错过了转换文件夹 – 天哪！

另一个错误：

clang: error: invalid argument '-install_name qm-vamp-plugins.a' only allowed with '-dynamiclib'
make: *** [qm-vamp-plugins.a] Error 1

让我们再次修复Makefile.osx：

CFLAGS := -O3 -ftree-vectorize -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -arch armv7 -I../vamp-plugin-sdk -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/System/Library/Frameworks/Accelerate.framework/Frameworks/vecLib.framework/Headers/ -DUSE_PTHREADS

CXXFLAGS  := $(CFLAGS)

LDFLAGS   := -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -arch armv7 -lqm-dsp ../vamp-plugin-sdk/libvamp-sdk.a -framework Accelerate -lpthread

好的,现在错误是架构未定义的符号错误：长期看看要点here
喜欢：

"std::cerr",referenced from:
  "typeinfo for std::istream",referenced from:
  "std::ostream::put(char)""
  std::ostream::operator<<(int)",

这让我想起了boost C库！

所以我需要得到提升,为iOS编译然后将它包含在Makefile中它应该工作,不是吗？这可能需要很长时间……

所以现在这样做

macbookproloreto:vamp-plugin-sdk loreto$echo $'\360\237\215\272'

从here开始,在iOS框架发布后获得提升并添加

-I /用户/洛雷托/项目/ AUdio / LIBS /升压 – IOS /距离/ boost.framework /接头/

我有同样的错误…呃我想我在这里错过了标准的C库！

macbookproloreto:Headers loreto$locate libc++.dylib | grep iPhoneOS7.0
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/lib/libc++.dylib

答对了！

所以

-I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/lib/libc++.dylib

再次出错(doh)！

试图没有成功

-I/usr/lib/libstdc++.dylib
   -lstdc++

坚持一个非常简单的链接问题.

再次.

macbookproloreto:vamp-plugin-sdk loreto$echo $'\360\237\215\272'

错误中最有趣的部分是第一个正在编译的静态库：

make -f build/osx/Makefile.osx

c++ -o qm-vamp-plugins.a g2cstubs.o plugins/AdaptiveSpectrogram.o plugins/BarBeatTrack.o plugins/BeatTrack.o plugins/DWT.o plugins/OnsetDetect.o plugins/ChromagramPlugin.o plugins/ConstantQSpectrogram.o plugins/KeyDetect.o plugins/MFCCPlugin.o plugins/SegmenterPlugin.o plugins/SimilarityPlugin.o plugins/TonalChangeDetect.o plugins/Transcription.o libmain.o -L../qm-dsp -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -arch armv7 -lqm-dsp ../vamp-plugin-sdk/libvamp-sdk.a -framework Accelerate -lpthread
Undefined symbols for architecture armv7:
  "std::basic_stringbuf<char,std::char_traits<char>,std::allocator<char> >::str() const",referenced from:
      _VampPlugin::Vamp::RealTime::toString() const in libvamp-sdk.a(RealTime.o)
      _VampPlugin::Vamp::RealTime::toText(bool) const in libvamp-sdk.a(RealTime.o)
  "std::basic_ios<char,std::char_traits<char> >::widen(char) const",referenced from:
      _VampPlugin::Vamp::PluginAdapterBase::Impl::getDescriptor() in libvamp-sdk.a(PluginAdapter.o)

在这里我们可以看到编译的静态库之一不包含正确的体系结构.

我这里有两个静态库：

lqm-dsp ../vamp-plugin-sdk/libvamp-sdk.a

如果我运行otool,我可以看到两者的cpu时间都是ARM7：

macbookproloreto:qm-vamp-plugins loreto$otool -hv ../vamp-plugin-sdk/libvamp-sdk.a
Archive : ../vamp-plugin-sdk/libvamp-sdk.a
../vamp-plugin-sdk/libvamp-sdk.a(PluginAdapter.o):
Mach header
      magic cputype cpusubtype  caps    filetype ncmds sizeofcmds      flags
   MH_MAGIC     ARM         V7  0x00      OBJECT     4       1128 SUBSECTIONS_VIA_SYMBOLS

那么Developer / SDKs / iPhoneOS7.0.sdk /usr/lib / libc .dylib有什么问题呢？
