Question

尝试构建Unix QuickFIX引擎时，在./bootstrap

之后出现以下错误

warning:macro 'AM_PATH_XML2' not found in library

据我所知，libxml2已经附带了XCode OS X Mountain Lion。我发现一个答案建议下载libxml2-dev，虽然我找不到使用HomeBrew的软件包我对OS X和Xcode的编程以及移植Unix应用程序都比较陌生，所以我不确定我到底有什么。

Answer 1

我做了

brew install libxml2

然后我四处寻找AM_PATH_XML2中的宏/usr/local/Cellar/libxml2/2.8.0/share/aclocal/libxml.m4。这是所有开发包的内容，然后我与我在本地的Ubuntu / Vagrant虚拟对比，工作正常并记得：

brew link --force libxml2

将符号链接放在/usr/local/share/aclocal。

中

现在我正在建设，但我也需要汽车制造商，所以回顾一下

brew install automake autoconf libtool libxml2                                                            
brew link libxml2

Answer 2

该警告来自Autoconf，并抱怨configure.in文件引用宏AM_PATH_XML2，但未定义。它应该在quickfix源文件aclocal.m4中定义，所以看起来你的autoconf版本没有找到它。您可以尝试修改bootstrap以运行autoconf -I .

Answer 3

我只是在尝试在Mac上构建oath-toolkit时遇到此问题。使用libxml.m4安装后，我可以通过为brew install libxml2创建符号链接来克服此错误。

ln -s /usr/local/opt/libxml2/share/aclocal/libxml.m4 /usr/local/share/aclocal/libxml.m4

我知道这个问题被问了7年多了，但是花了我一段时间才整理出这个解决方案。希望对您有所帮助。我能够在运行aclocal时重现该问题。 configure.ac:38: warning: macro 'AM_PATH_XML2' not found in library错误。然后，我运行aclocal --print-ac-dir返回了/usr/local/Cellar/automake/1.16.1_1/share/aclocal。该目录包含一个dirlist文件。

cat /usr/local/Cellar/automake/1.16.1_1/share/aclocal/dirlist 
/usr/local/share/aclocal
/usr/share/aclocal

第一个目录包含所有其他符号链接。

ls -al /usr/local/share/aclocal

lrwxr-xr-x   1 cameron  admin   51 Aug 27 20:15 pkg.m4 -> ../../Cellar/pkg-config/0.29.2/share/aclocal/pkg.m4

按照这种模式，我可以做到：

ln -s /usr/local/Cellar/libxml2/2.9.9_2/share/aclocal/libxml.m4 /usr/local/share/aclocal/libxml.m4

但是我选择使用此符号链接，以便此答案适用于各种版本。

ls -al /usr/local/opt/libxml2
lrwxr-xr-x  1 cameron  admin  25 Sep 20 09:35 /usr/local/opt/libxml2 -> ../Cellar/libxml2/2.9.9_2

OSX上的libxml2和libxml2-dev
