Question

我需要在运行Mac OS X Yosemite的MacBook Pro上安装libmemcached。

我已经安装了memcached守护进程，但是为了使PHP memcached.so PECL扩展能够工作，我需要安装libmemcached。

我从 https://launchpad.net/libmemcached/+download 下载了tar.gz，查看了文件README.FIRST：

Hi!

If you are getting this code from http://launchpad.net/libmemcached then
continue reading. Otherwise these directions are not for you (well maybe...).

To obtain code from http://bazaar.launchpad.net/libmemcached you will need to
issue the following command:

bzr branch lp:libmemcached

Once the tree is cloned you will need to build the "configure" script. You
can do this by running the script:

./bootstrap.sh autoreconf

It will set up all of the files you need to build libmemcached. At that
point it is just the typical "./configure; make; make test; make install"

For a tarball release do a "make dist" and for an RPM type "make rpm".

For patches, we prefer you push a branch to launchpad and then submit that 
branch to be merged. For more information, see:

https://help.launchpad.net/Code/UploadingABranch
https://help.launchpad.net/Code/Review

Thanks and keep hacking!

所以我安装了Bazaar，然后输入以下命令：

bzr branch lp:libmemcached

但我得到的是：

    bzr: warning: unsupported locale setting
  bzr could not set the application locale.
  Although this should be no problem for bzr itself, it might
  cause problems with some plugins. To investigate the issue,
  look at the output of the locale(1p) tool.
Not checking SSL certificate for xmlrpc.launchpad.net.
You have not informed bzr of your Launchpad ID, and you must do this to
write to Launchpad or access private data.  See "bzr help launchpad-login".
bzr: ERROR: Target directory "libmemcached" already exists.

如果我尝试运行 ./ configure 然后 make ，我会收到很多警告：

./libmemcached/server.hpp:82:62: warning: implicit conversion loses integer precision: 'uint64_t'
  (aka 'unsigned long long') to 'uint32_t' (aka 'unsigned int') [-Wshorten-64-to-32]

libmemcached/csl/scanner.cc:2070:2: warning: 'register' storage class specifier is deprecated
      [-Wdeprecated-register]

libmemcached/byteorder.cc:75:10: error: use of undeclared identifier 'htonll'

还有2个错误：

2 errors generated.
make[1]: *** [libmemcached/libmemcached_libmemcached_la-byteorder.lo] Error 1
make: *** [all] Error 2

所以实际上我无法安装libmemcached。有什么选择我可以尝试，我该如何解决这个问题？为什么所有这些错误？

感谢您的关注！

希望得到一些帮助。

Answer 1

我通过更改配置脚本和其中一个源文件，设法通过libmemcached在OSX 10.10.3上编译和安装。

在configure我更改了行：

if ac_fn_cxx_try_compile "$LINENO"; then :
    ac_cv_have_htonll=yes
else
    ac_cv_have_htonll=no
fi

为：

ac_cv_have_htonll=no

然后在clients/memflush.cc我更改了2个实例：

if (opt_servers == false)

为：

if (opt_servers == NULL)

之后，通常configure，make，sudo make install工作正常（尽管有很多警告）。然后该库似乎工作正常，在我的情况下使用pylibmc。

我知道很久以前就问过这个问题，但问题出在我看来的其他地方，即缺少的问题。

这是我在（macOS High Sierra 10.13）修复问题的方法：

在bytesorder.cc中，我在byteorder.h之后添加了这3行：

#if defined HAVE_HTONLL && defined HAVE_SYS_TYPES_H
#include <sys/types.h>
#endif

如何在Mac OS X Yosemite 10.10上安装libmemcached以便在Mamp 3上安装memcached.so PHP扩展？
