为iOS构建静态Graphviz库 [英] Build static Graphviz libraries for iOS

问题描述

我正在尝试为Graphviz构建静态库，将它们包含在iOS应用程序中，但我无法让它工作。这是我到目前为止所做的，使用graphviz 2.28.0]，Xcode 4.1，OSX 10.7，我的目标是iOS模拟器。

I am trying build the static libraries for Graphviz to include them in in an iOS app, but I can't get it to work. Here's what I have done so far, using graphviz 2.28.0], Xcode 4.1, OSX 10.7 and I am targeting the iOS simulator.

我发现 Glen Low的配置说明，并通过一些明智的猜测将这些更新为：

I found Glen Low's configure instructions, and with some informed guesswork updated these to:

./configure --build=i486-apple-darwin --host=arm-apple-darwin9 --disable-dependency-tracking --enable-shared=no --enable-static=yes --enable-ltdl-install=no --enable-ltdl=no --enable-swig=no --enable-tcl=no --with-codegens=no --with-fontconfig=no --with-freetype2=no --with-ipsepcola=yes --with-libgd=no --with-quartz=yes --with-visio=yes --with-x=no --with-cgraph=no CC="/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2" CPP="/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2 -E" CXX="/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/g++-4.2" CXXCPP="/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/g++-4.2 -E" OBJC="/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2" LD="/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ld" CPPFLAGS="-arch armv6 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk -miphoneos-version-min=4.0" CXXCPPFLAGS="-arch armv6 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk -miphoneos-version-min=4.0"

这有效，但随后make会运行一段时间并出错：

This works, but then the "make" runs for a while and errors out with:

Making all in gvpr
  CCLD   mkdefs
ld: warning: ignoring file mkdefs.o, file was built for armv6 which is not the architecture being linked (i386)
ld: warning: ignoring file /usr/local/lib/libSystem.dylib, missing required architecture i386 in file

make[3]: *** [mkdefs] Error 1
make[2]: *** [all-recursive] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

我不太了解所有的架构规范，所以非常欢迎任何帮助让它工作。

I don't quite understand all the architecture specifications, so any help to get this to work is most welcome.

推荐答案

我得到了这工作。构建脚本在尝试生成可执行文件时最终失败，因为它是为i386而不是x86或x86_64编译的，但所有库都构建得很好。

I got this working. The build script fails at the end when it tried to make an executable since it's compiled for i386 instead of x86 or x86_64 but all the libraries build just fine.
