Question

我正在尝试在iOS 4.2中构建libCURL，我在终端中执行了一些步骤。步骤是：

cd curl-7.21.2
export CC=/Developer\ 4.2/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-gcc-4.0.1
export CFLAGS="-isysroot /Developer\ 4.2/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk"
export LDFLAGS="-isysroot /Developer\ 4.2/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk -Wl,-syslibroot /Developer\ 4.2/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk"
export CPP=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/cpp
./configure --disable-shared --without-ssl --without-libssh2 --without-ca-bundle --without-ldap --disable-ldap --host=arm-apple-darwin10

但点击进入终端后显示这些警告和错误：

See `config.log' for more details

这是config.log：

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by curl configure -, which was
generated by GNU Autoconf 2.68.  Invocation command line was

  $ ./configure --disable-shared --without-ssl --without-libssh2 --without-ca-bundle --without-ldap --disable-ldap --host=arm-apple-darwin10

基于Bavarious评论，我在每一步都更改了所有命令，这些是更新：

export CC='\"/Developer 4.2/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-gcc-4.0.1\">
export CFLAGS="-isysroot \"/Developer 4.2/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk\""
export LDFLAGS="-isysroot \"/Developer 4.2/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk -Wl,-syslibroot \"/Developer 4.2/Platforms/icleaPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk"""
export CPP='\"/Developer 4.2/Platforms/iPhoneOS.platform/Developer/usr/bin/cpp">
./configure --disable-shared --without-ssl --without-libssh2 --without-ca-bundle --without-ldap --disable-ldap --host=arm-apple-darwin10

但它使终端没有执行命令。

我不明白它是什么，有人可以告诉我吗？

谢谢

Answer 1

如果您在Lion上，请尝试使用标记--with-gcc=clang

进行安装

正在运行rvm requirements更详细地解释了这一点：

Xcode 4.2:
 * is only supported by ruby 1.9.3+ using command line flag: --with-gcc=clang
 * it breaks gems with native extensions, especially DB drivers.

Xcode 4.2 users - please be warned - 
in case of any compilation issues 
 * downgrade to Xcode 4.1
 * or install osx-gcc-installer
and reinstall your rubies.

问题是路径名中的空格。更重要的是，除非将其删除，否则无法轻松修复。

麻烦在于日志文件 - 它只是出现在它的中间...

要获得包含空格的路径，您必须能够确保每当使用CC时，路径都用双引号括起来。您还必须伪造CFLAGS值，以便路径不会被拆分，但-isysroot与导致-isysroot的路径分开。

如果您想冒险，可以尝试使用：

export CC="\"/Developer 4.2/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-gcc-4.0.1\""
export CFLAGS="-isysroot \"/Developer 4.2/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk\""

它有可能发挥作用，但我不想依赖它。基本上，它在环境变量值的明智选择点添加双引号，希望shell能够将它们保存在正确的位置。我认为它不会起作用，但值得一试。

我建议在没有空格的情况下重命名安装软件的路径，可能是：

/Developer-4.2/Platforms/...

（我有一个简短的目录$HOME/External Source Repositories，其中包含git和svn以及hg（Mercurial）外部源存储库的副本区域，包括提到的VCS。 VCS可以使用名称中的空格，但下载的存储库（包括VCS自己的构建系统）的构建过程不是（git包含的，IIRC）。该目录现在称为$HOME/External-Source-Repositories 。）
