在Mac OS X上编译apache模块mod_转换的未定义符号

我试图在MacOSX10.6上编译mod_转换，但在运行make时出现了一个ld错误。多亏了diciu，我添加了一些CFLAG，解决了大多数链接问题，但我仍然无法使apreq2链接正常工作

$ CFLAGS="-lxml2 -lxslt -L/opt/local/lib -lapreq2" ./configure --with-apr=/opt/local/bin/apr-1-config --with-apr-util=/opt/local/bin/apu-1-config --with-apxs=/opt/local/apache2/bin/apxs --with-apreq2=/opt/local/bin/apreq2-config $CFLAGS=“-lxml2-lxslt-L/opt/local/lib-lapreq2”。/configure--with-apr=/opt/local/bin/apr-1-config--with-apr-util=/opt/local/bin/apu-1-config--with-apxs=/opt/local/apache2/bin/apxs--with-apreq2=/opt local/bin/apreq2-config …剪断

这是来自的mod_变换

看起来您的配置运行无法检测到对libxml2的依赖：

nm -arch x86_64 /usr/lib/libxml2.dylib | grep _xmlXPathNewFloat
    0000000000054896 T _xmlXPathNewFloat

要修复编译，您可以在gcc中添加“-lxml2”，即：

/usr/bin/gcc-4.2 -o .libs/http.so -bundle .libs/http_la-http.o ... -lxml2

但这通常由配置创建的Makefile处理。 请尝试通过configure.log查找libxml2设置不正确的原因
