配置：错误：C编译器无法在mac os终端中创建可执行文件

Question

我试图在iOS 4.2中构建libCURL，我在终端中执行一些步骤。 的步骤是：

1. cd curl-7.21.2
2. export CC=/Developer\ 4.2/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-gcc-4.0.1
3. export CFLAGS="-isysroot /Developer\ 4.2/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk"
4. 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"
5. export CPP=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/cpp
6. ./configure --disable-shared --without-ssl --without-libssh2 --without-ca-bundle --without-ldap --disable-ldap --host=arm-apple-darwin10

但自来水后进入终端告诉我这些警告和错误：

See `config.log' for more details 

这是的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

上Bavarious意见的基础上，我已经改变所有的命令中的每一步，这些是更新：

1. export CC='\"/Developer 4.2/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-gcc-4.0.1\">
2. export CFLAGS="-isysroot \"/Developer 4.2/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk\""
3. 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"""
4. export CPP='\"/Developer 4.2/Platforms/iPhoneOS.platform/Developer/usr/bin/cpp">
5. ./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

如果你是狮子尝试与标签安装：--with-gcc=clang

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.

的问题是在路径名的空间。更重要的是，除非你删除它们，否则不是一个简单的解决方法。

麻烦的是在日志文件 - 它只是显示它的中部附近...

为了获得与空间的路径工作，你必须要能够保证每当使用CC时，路径都用双引号括起来。您还需要限制CFLAGS值，以便路径不会分裂，但-isysroot与通向-isysroot的路径是分开的。

如果你想冒险，你可以尝试使用：

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\"" 

有一个外部的机会，它会工作，但我不想依赖它。基本上，它会在环境变量值的明智选择的点上添加双引号，希望shell能够设法将它们保留在正确的位置。我认为它不会起作用，但它可能值得一试。

我建议重新命名，你有没有空间安装软件的路径，也许是因为：

/Developer-4.2/Platforms/... 

（我有一个目录$HOME/External Source Repositories简单地说，与地区为git和svn和hg（水银）副本外部源代码库，包括所提到的VCS，虽然名称中包含空格，但VCS仍然可用，但下载的代码库（包括VCS自己的构建系统）的构建过程不是（包括git，IIRC）。改为$HOME/External-Source-Repositories）。
