I'm having a few issues with the PHP function iconv, which I've tracked down the the iconv implementation. As the manual states, "Note that the iconv function on some systems may not work as you expect. In such case, it'd be a good idea to install the GNU libiconv library." http://uk3.php.net/manual/en/intro.iconv.php
I've downloaded the libiconv library from http://www.gnu.org/software/libiconv/ and installed it without any problems using:
$ ./configure --prefix=/usr/local
$ make
$ make install
My problem now is how to link this installation to PHP? From what i've read I need to recompile PHP with --with-iconv-dir=/usr/local/
but how do I do this on CentOS? I installed php with yum install php.x86_64
I tried yum reinstall php but when I service httpd restart my phpinfo reads the same, glibc.
Is there a better way to install libiconv on CentOS? If not how do I get PHP using this installation without upsetting yum?
Many thanks in advance
compiled php from source seems to be the way
php -m > /tmp/php.modules to list of compiled module for php
backup your current php.ini
yum uninstall php
download the php
and base on your existing module + iconv - almost all steps has been detailed here : http://www.php.net/manual/en/install.unix.apache2.php#90478 (except never advise u to backup php.ini)
You should manually recompile the php iconv extension (in the php-x.y.z/ext/iconv/ subdirectory) after manual changing of the configure script to force it to select GNU libiconv instead of glibc's iconv. See my answer for the similar Stack question.

I followed the instructions outlined here:
Install PHP Internationalization extension (Intl) on XAMPP on Mac
Ran sudo pecl install intl
selected the correct files from the Cellar
then this error happened:
/private/tmp/pear/temp/intl/intl_error.h:24:10: fatal error:
'ext/standard/php_smart_str.h' file not found
include
^ 1 error generated. make: *** [php_intl.lo] Error 1 ERROR: `make' failed
No matter, did some research and found out that PHP 7.0.8 deprecated php.smart_str.h to php.smart_string.h
So given my scant knowledge of C++ I copied smart_string.h to smart_str.h and renamed all the headers from STRING to string.....
re-ran pecl -no luck....more errors......without knowing where the .c files are and remaking php (not really interested in going that far) since anyway I'm using XAMPP so that ended that option.
I have php 5.5 on my mac, deep in the usr/local/bin folder
so next step was to get pecl to use those files and generate an intl.so file....
Did that....I have the intl.so file so put it in the 'extensions' folder in XAMPP (for reference: /Applications/XAMPP/xamppfiles/lib/php/extensions/no-debug-non-zts-20151012)
Ran php and came up with this error:
Warning: PHP Startup: Unable to load dynamic library
'/Applications/XAMPP/xamppfiles/lib/php/extensions/no-debug-non-zts-20151012/intl.so'
- dlopen(/Applications/XAMPP/xamppfiles/lib/php/extensions/no-debug-non-zts-20151012/intl.so,

Expected in: flat namespace in
/Applications/XAMPP/xamppfiles/lib/php/extensions/no-debug-non-zts-20151012/intl.so
in Unknown on line 0
I imagine it has to do with different versions?
In any case I can't get pecl to install intl without a make error in PHP 7.0.8 on XAMPP. There is no documentation on this and you'd think that if you deprecate a header.h file you'd update all extensions?
Install intl.so in PHP 7 seems impossible?
After a lot of research I was finally able to resolve this. Detailed steps here:
before you begin, check which php path is set. it should be /Applications/XAMPP/xamppfiles/bin/php. If not you can change it by PATH="/Applications/XAMPP/xamppfiles/bin:${PATH}". more detail here
Overall idea is to build the intl-extension from PHP source code on your own. Before you begin make sure you have installed Xcode. Also, install the latest version of autoconf. this might help:
brew install autoconf
Next download the version of PHP you use in XAMPP from php.net. I am using 7.1.18. This version worked for me: php-7.1.31, I’m guessing if you follow the steps it might work for 7.0 or 7.2 as well. Do let me know if it does or doesnt, I’ll update this post. Do not use PHP 7.3 for Magento 2.3.0, it is not supported.
Extract the tar.gz file using (I extracted it inside ~/Downloads/ folder )
tar -xzvf php-7.1.31.tar.gz
cd into the extracted folder
cd php-7.1.31
change to subfolder ext/intl
cd ext/intl/
Run these commands to build the extension
/Applications/XAMPP/bin/phpize
./configure --enable-intl --with-php-config=/Applications/XAMPP/bin/php-config --with-icu-dir=/Applications/XAMPP/xamppfiles/
make
sudo make install
you can now delete all files you downloaded and also the extracted folders.
Open /Applications/XAMPP/xamppfiles/etc/php.ini , and add extension=intl.so
Restart your Apache using XAMPP GUI and it should work.
So far, it seems that extension intl.so for php is bundled with php
and should be compiled with php (intl --enabled). XAMPP does not support this (as of Oct 2016), MAMP does. I do not know about other distros. However, if you're willing to recompile PHP 7, it's worth it just to do that and enable it during compiling.
So....I ran with MAMP. Then I decided that I would simply install apache 2.4 and php 7 and Mysql without the stack and the junk that comes with MAMP or XAMPP and everything works like a charm... so if you need to use CakePHP or intl support etc... just drop XAMPP/MAMP and go with a standard install. I used homebrew (MacOS) and everything is working fine.
Update: As regards Windows, XAMPP does not default it, but you can add the module (dll) in php.ini and works like a charm
The error means that XAMPP doesn't have PHP compiled with intl. You may try:
pecl install intl
but probably it won't work as well.
See: PHP Bug #72879 Pecl install intl make error with PHP 7.0.8.
As for the workaround, try installing memcached extension instead of memcache, e.g.
pecl install memcached
Note: It also requires libmemcached package/library to be installed beforehand. For macOS, install via: brew install libmemcached.
If you wanna try without homebrew, with native apache and php, look at my aswer here: https://stackoverflow.com/a/55131868/3692846
Debian : 7.4
I have some difficulty to make ssh2 work with php5. i didn't find a solution on other topics and i search a LOT ! all has been well installed according to debian outputs but it still doesn't work.
This is what i'v done
Package installed :
- php5
- php5-dev
- libssh2-php
- libssh2-1-dev
I used PECL to install
pecl install -f ssh2
I just press enter for auto prefix.
And extension=ssh2.so to /etc/php5/apache2/php.ini
Restart more than one time apache2.
But the package ssh2 still not appear in output of php -m and says that ssh2_connect is undefined
I totally out of resources to make it works, so please can anybody helps me ?
Here some info provided by phpinfo() :
extension_dir /usr/local/lib/php/extensions/no-debug-non-zts-20100525/
extension version 0.12
libssh2 version 1.4.3
banner SSH-2.0-libssh2_1.4.3
If you need i can give more informations
I use phpseclib's libssh2-compatibility-layer to avoid having to install libssh2. You can use all the libssh2 functions without having it installed thanks to the use of phpseclib.
If you're writing your application from scratch maybe try just using phpseclib from the onset intsead of libssh2.
I'm trying to configure PHP 5.5 on MAMP, following this post:
Having problems while try to install OAUTH with PECL in MAMP on mac OS lion.
After I move the downloaded PHP folders into MAMP/bin/php (I also tried to create a directory of /php5.5.14/include/php as described in the post above) and ran ./configure.
I got an error:
checking for iconv support... yes
checking for iconv... no
checking for libiconv... no
configure: error: Please specify the install prefix of iconv with --with-iconv=< DIR >
Where can I "specify the install prefix" or how can I solve this problem?
Thanks!!
With Homebrew:
brew install libiconv
then
./configure --with-iconv=$(brew --prefix libiconv)
brew --prefix libiconv normally evaluates to /usr/local/opt/libiconv
Do exactly as the error says in your console. It's looking for iconv but it can't find it.
./configure --with-iconv=pathToIconv
I guess we should probably check to see if iconv is installed by running "iconv --help" if it's not installed you can install it with homebrew, or you could add the existing files to your PATH variable. I am not sure how mamp works in this scenario.. PHP should use iconv if it is installed on the machine. Due to the way mamp contains itself it may be full filling this dependency in a weird way. As I understand it best practice is to have iconv built into the php installation so you should put the effort into tracking down the path.To my understanding you can install it without iconv and as long as the dependency is being fulfilled it will run as expected.
./configure --without-iconv
I had iconv installed with MacPorts so the executable was located at /opt/local/bin/iconv. Specifying ./configure --with-iconv=/opt/local did the trick.
I am using phpbrew to install iconv extension into php.
When i tried to install iconv with /usr/local/Cellar/libiconv/1.16
phpbrew ext install iconv -- --with-iconv=/usr/local/Cellar/libiconv/1.16
It returned error:
checking if awk is broken... no
checking for iconv support... yes, shared
checking for iconv... no
checking for libiconv... no
configure: error: Please specify the install prefix of iconv with --with-iconv=<DIR>
It solved using brew's iconv:
brew install homebrew/core/libiconv
phpbrew ext install iconv -- --with-iconv=$(brew --prefix libiconv)
Result:
===> Enabling extension iconv
[*] iconv extension is enabled.
Done.
I am trying to install pthreads for PHP, which is here.
In PHP manual of extention it says:
To enable pthreads support, configure PHP with --enable-maintainer-zts
and --enable-pthreads.
I have a CentOS server which has PHP installed but I cant figure out how to reconfigure it with these settings on, I checked my phpinfo() can see current ./configure options.
I will happy if someone can show me how to reconfigure my php. Do I need to uninstall current PHP first then install another or is there any way to run this ./configure command easily. I have SSH access to my server.
You could try install using PECL:
http://pecl.php.net/package/pthreads.
How to install PECL extensions:
http://php.net/manual/en/install.pecl.php
pecl install pthreads
I've written a tutorial about exactly this - Compile PHP with pthreads and ZTS enabled.
You must compile PHP as there are no prebuilt packages.
To reconfigure everything you'd use ./configure mainly.
if centos does not provide a thread safe version, you must compile php by own.
You have to build pthreads for your centos op system. After that you can use it as extension...
Use the following tutorials
http://blog.slowbro.org/2013/08/compiling-php-55-with-pthreads-on-centos/
http://eddmann.com/posts/compiling-php-5-5-with-zts-and-pthreads-support/
Or simply read the manual...
http://www.php.net/manual/en/pthreads.installation.php
I have installed MAMP and the PHP it came with wasn't compiled with ncurses. I've tried to use port to install ncurses and it seems that it already exists on my system so now I was wondering if there was a way to get PHP to use it without having to recompile PHP --with-ncurses.
In other words: Can PHP be configured to use ncurses without the recompilation?
I'm sorry for the late answer but this can actually be done quite easily with MAMP.
I have done this on my MacBook running OS X Snow Leopard.
Your MAMP directory contains the tar file of the php source code. MAMP version 1.8.4 ships with php-5.2.11.tar located here: /Applications/MAMP/bin/php5/
cd /Applications/MAMP/bin/php5/
tar -xvf php-5.2.11.tar
cd php-5.2.11/ext/ncurses
/Applications/MAMP/bin/php5/bin/phpize
./configure --with-php-config=/Applications/MAMP/bin/php5/bin/php-config
make
make install
Afterwards you just need to add the ncurses.so extension to the MAMP php.ini
echo "extension=ncurses.so" >> /Applications/MAMP/conf/php5/php.ini
php -i | grep ncurses
This gives me:
ncurses
ncurses support => enabled
ncurses library version => 5.7
You can also do this with the PCNTL extension ;) ;)
Cheers!
According to the manual, ncurses must be compiled in. Some extensions can be compiled as shared libraries (dll/so) and loaded dynamically, but some can't. Seems that ncurses can't.
I don't know a lot about how mac packages are structured, but isn't it a bsd/ports style installation? In that case, just find the package and configure + recompile it.
Edit: I see that mamp is a binary distribution. You're out of luck then. I would suggest that you install at least php from sources. It's very useful to be able to install new extensions etc. It's fairly straight forward to compile php, so even if you aren't completely confident with compiling stuff, you should be able to huddle through it.
