在 Mac OS X 10.7.2 上构建 libjingle 时出错，例如“error: string.h: No such file or directory”

Question

我未能在 Mac OS X 10.7.2 上构建 libjingle。当我根据 libjingle 的 README 运行 $path_to_swtoolkit/hammer.sh 时，输出如下。

MBP17:talk rei25$ ~/Desktop/swtoolkit/hammer.sh

我确定我的 Mac 中存在 string.h、assert.h 等。 我也试过cd到目录expat-2.0.1并运行./configure和make，成功了。 我已经在网上搜索过这个问题，但对我来说似乎没什么用。所以，如果你知道为什么，谢谢你告诉我！

P.S 我的问题好像是这样的：http://groups.google.com/group/googletestframework/browse_thread/thread/e8ed5a3f410b7ec7/a8ba72e727801fc8?show_docid=a8ba72e727801fc8

Answer 1

我对狮子也有同样的问题。正如wayon 指出的那样，开发人员似乎对特定的 SDK 版本“/Developer/SDKs/MacOSX10.5.sdk”进行了硬编码。截至发帖时，最新版本是 Xcode 4 附带的 10.7。在修复了构建中存在的其他几个问题后，我不确定它们是否与 OS X 或只是一个损坏的构建脚本有关对于 lib 叮当声。

这是修复我发现的其他问题的补丁，libjingle patch。 此外，您可能必须通过stackoverflow swtoolkit fix 修复 swtoolkit。

我没有检查单元测试是否通过，但至少现在可以编译了。

Answer 2

我遇到了同样的问题。

在我的情况下，问题是由目录“talk”（源代码树的顶层）中 main.scons 文件中的错误 CCFLAGS 引起的。 '-isysroot' 参数的路径错误：

CCFLAGS = [ '-arch'，'i386'， '-isysroot', '/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.0.sdk',

'-fasm-blocks', ],

我的 mac 上没有 iPhoneSimulator4.0.sdk，只有 iPhoneSimulator4.3.sdk 和 iPhoneSimulator5.0.sdk。

所以，我只是将 4.0 替换为 5.0 并得到以下内容：

CCFLAGS = [ '-arch'，'i386'， '-isysroot', '/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.0.sdk', '-fasm-blocks', ],

这对我有帮助。

要解决此问题，请尝试以下操作：

1. 检查 /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/ 文件夹中的 sdk 版本
2. 在源代码树顶部的 main.scons 文件中为 -isysroot 参数设置适当的路径（在我的例子中是 ilibjingle/gtalk/libjingle-0.5/talk）：

然后尝试再次运行 $path_to_swtoolkit/hammer.sh。

希望对你有帮助。

Answer 3

尝试将以下包含添加到您的 main.scons 文件中：

main.scons：

... // more than 300 lines and the you will find the mac_env section

mac_env.Append(
  CPPDEFINES = [
    'OSX',
  ],
  CCFLAGS = [
    '-m32',
    '-arch', 'i386',
    '-isysroot', '/Developer/SDKs/MacOSX10.5.sdk',
    '-fasm-blocks',
    '-I/usr/include', <--- Add this line and this will tell to scons where is your includes
...
