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

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:

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.

What happens when you try to compile a C stub program (int main(){return 0;}) with cc -licudata -o test test.c? – Substantialize

I tried as you suggested, and the stub test.c program compiles without any error messages. – Trin

Do you need to use PECL? You may want to consider using homebrew as it works very efficiently. brew.sh – Bryner

Well, good question. I got a new Mac, and after reading about the SIP constraints, I was thinking it might be best to simply install the applications and libraries individually. It might also be good if I want to learn more about the various switches and options, at least for the software I use more frequently. To your point, I could see that being overkill, too; the bad old days for the average user. – Trin

Where would I look to see any notes in how the package in Homebrew was prepared? Someone must have ran into similar types of errors, when preparing packages for Homebrew. So, is there a place to look that up? – Trin

I couldn't reproduce this error, what php version are you using. – Secrecy

See this github.com/Homebrew/homebrew-php/issues/1710. I use brew too and maybe "brew update && brew reinstall php56 && brew reintsasll icu4c" would work – Secrecy

The Mac Book Pro laptop came installed with php v5.5.31. – Trin

What is your icu4c version? – Secrecy

The icu4c version I downloaded was 51.2 because of the PECL binary dependency, but now I am reading it again, I think I should be looking at the PHP docs to find out what version to use. I tried 51.2, 52.1, and the latest 57.1, which all seemed to yield the same error. – Trin

Let us continue this discussion in chat. – Trin

Isn't intl included with PHP for a long time now? Have you set DYLD_LIBRARY_PATH before running pecl? – Moke

Answer 1

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.

I just went with using brew, so I won't be able to check, but thank you for your help! – Trin

Answer 2

Maybe you can try just this:

brew install php56-intl

Forta

Answer 3

You might consider looking at these threads (https://github.com/Homebrew/homebrew-php/issues/1701) and (https://github.com/Homebrew/homebrew-php/issues/1710). I tried to reproduce your error but I failed. The most probable reason would be an icu4c that is not linked.

Try using brew link --force icu4c

I tried using php70 and

sudo pecl install intl

failed. I tried using php56, everything ran smoothly.

Try running php -v master, something like this should show up

I am using php 5.5, it was built Feb 20, 2016 – Trin

I can try building php 5.6, and see if building that extension works. – Trin

@BiagioArobba you can brew install php56 and brew unlink php55 – Secrecy

Wait right you compiled it, right go ahead and compile php56 – Secrecy

Ok, I tried upgrading things. So, I compiled the latest ICU 57.1 and PHP 5.6.20, and got the same error message ld: file not found: ... for architecture x86_64 – Trin

Just a note. I am trying to stay away from using Homebrew. – Trin

Answer 4

Try run:

brew install homebrew/php/php56-intl
