ios - 为 ios 7 armv7s 编译 GMP

Question

我正在尝试在我的 Macbook 上为 armv7s 和 iphone 模拟器 (i386) 编译 gmp 6.0.0，但我无法让它工作。我阅读了一些相关问题( Build GMP for iOS ， Building a C library (GMP) for arm64 iOS )并将其配置为:

./configure \
CC="/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang++ -Wno-error -Wno-implicit-function-declaration" \
CPP="/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang++ -E" \
CPPFLAGS="-arch armv7s -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.1.sdk/ -miphoneos-version-min=7.0" \
--host=arm-apple-darwin --disable-assembly

配置工作正常，但是当我运行 make 时失败:

clang: warning: treating 'c' input as 'c++' when in C++ mode, this behavior is deprecated
div_qr_1n_pi1.c:218:3: error: expected ')'
  add_mssaaaa (u2, u1, u0, u0, up[n-2], p1, p0);

          ^
2 errors generated.
make[2]: *** [div_qr_1n_pi1.lo] Error 1
make[1]: *** [all-recursive] Error 1

我不知道下一步该做什么，如果有人能给我提示下一步该做什么就太好了。

我下载了最新的快照，将 -no-integrated-as 添加到 cppflags 并将 clang++ 更改为 clang。配置后仍然运行良好，我收到错误:

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang `test -f 'gen-fac.c' || echo './'`gen-fac.c -o gen-fac
gen-fac.c:31:10: fatal error: 'stdio.h' file not found
#include <stdio.h>

我终于成功了。我重新安装了 xcode 命令行工具并进行了如下配置:

./configure \
CC="/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang" \
CFLAGS="-isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.1.sdk/ -Wno-error -Wno-implicit-function-declaration -miphoneos-version-min=7.0  -no-integrated-as -arch armv7s \
--host=arm-apple-darwin --disable-assembly --enable-static --disable-shared"

模拟器(i386)也是如此，并使用 lipo 来合并它们。

这里有 3 个占位符:

• iPhoneOS7.1.sdk 可以是您当前的 SDK。
• 7.0 您尝试为其编译库的操作系统的最低版本。
• armv7s 也可以是 armv7、arm64、i386。
