Question

I am trying to install the PHP Intl extension on my new Mac (El Capitan 10.11.4) using PECL, but there is a linking error during the make stage.

Here are the steps I took:

Installed PEAR to run on Mac
Compiled and installed the ICU library (version 51.2) into /usr/local/lib
Ran this command: sudo pecl install intl and there was an error (see below). I also tried compiling the extension directly from the PHP source code ("ext" folder) and received the same error message.

I am getting the following error:

ld: file not found: libicudata.51.dylib for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [intl.la] Error 1
ERROR: 'make' failed

It looks like:

The file is missing (even though it knows the correct ICU library version to look for). Maybe it truly can't find the file. The -L switch and related switches appear to point to the correct path /usr/local/lib path.
Then, there is also some sort of architecture mismatch. So, I ran file libicudata.51.dylib and it appears to be the right architecture.

Here is what file retuned:

$ file /usr/local/lib/libicudata.51.dylib
/usr/local/lib/libicudata.51.dylib: Mach-O 64-bit dynamically linked shared library x86_64

Has anyone run across this before? Or know how to compile PHP's Intl extension on the new Mac Book Pro (El Capitan 10.11.4)? I a hoping for some hints on where to look next, because I am a bit stumped here.

Answer 1

也许你可以试试这个：

brew install php56-intl

Answer 2

您可以考虑查看这些主题（https://github.com/Homebrew/homebrew-php/issues/1701）和（https://github.com/Homebrew/homebrew-php/issues/1710）。我试图重现你的错误，但我失败了。最可能的原因是没有链接的icu4c。

尝试使用brew link --force icu4c

我尝试使用php70和

sudo pecl install intl

失败。我尝试使用php56，一切顺利。

尝试运行php -v master，此类内容应显示

Answer 3

尝试运行：

brew install homebrew/php/php56-intl

Answer 4

我解决了这个问题，这是我的环境：

  操作系统：El Capitan 10.11.4
  PHP：php-7.0.5
  icu：55.1

关键点是使用--enable-rpath重新安装ICU：

./configure --prefix=/opt/oss/icu --enable-release --enable-shared --enable-rpath --enable-tools

如果您想知道原因，请以root身份运行

otool -L $YOUR_ICU_PREFIX/lib/libicudata.dylib
