Compiling PHP Intl extension on Mac Book Pro (El Capitan 10.11.4)

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:

  1. Installed PEAR to run on Mac

  2. Compiled and installed the ICU library (version 51.2) into /usr/local/lib

  3. 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:

  1. 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.

  2. 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.

Solution

  • I fixed this problem,here is my environment:

    OS : El Capitan 10.11.4
    PHP : php-7.0.5
    icu : 55.1

    the key point is reinstall ICU using --enable-rpath:

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

    If you want to know why,please run as root

    otool -L $YOUR_ICU_PREFIX/lib/libicudata.dylib

    to check if the first library is absolute path.
