Installation Error on OS X 10.11.6

[WalkerPnD]

Hi, @deuill . I'm making a portable server to help my graphic designers friends on FrontEnd development with golang/echo framework. https://github.com/walker-walks/quick_serv
They said it would be useful if the server executes php files. so I was trying to call and execute php from go in a way I don't have License problem..

So I'm trying to use go-php library but
I'm having the same issue with some people when I'm doing go get.

engine/context.go:11:11: error: 'main/php.h' file not found with <angled> include; use "quotes" instead
 #include <main/php.h>
          ^~~~~~~~~~~~
          "main/php.h

I don't know if it's correct but, I downloaded the php source file and put the php-7/main into go-php/engine/main and passed this part and them appeared another error which is.

In file included from engine/context.go:11:
./main/php.h:35:10: fatal error: 'zend.h' file not found
#include "zend.h"
         ^

I moved all the files were in php-7/Zend to go-php/engine/main. and Now I have the issue below that I can't understand.

In file included from engine/context.go:11:
In file included from ./main/php.h:35:
In file included from ./main/zend.h:31:
In file included from ./main/zend_types.h:27:
./main/zend_portability.h:48:11: fatal error: 'zend_config.h' file not found
# include <zend_config.h>

I wold be very happy if you could give me any suggestions.
thanks.

Hi @walker-walks, in order to get this compiled, you need to have php installed as a library.

To do this on MacOS, you need to get Homebrew installed, if you haven't yet, then install PHP:

brew install -v homebrew/php/php70 --enable-embed=shared

However, I haven't tested this on MacOS so YMMV. You will most likely need to add the full path to the include/php7 directory that Brew uses into the php7.go file, or wait for a branch for adding MacOS support.

[WalkerPnD]

I installed php shared library and added the full path.
now the error appears like this.

Did you build with -tags php7?

i.e.:

go build -tags php7

Unfortunately, you'll have to pass that in any build command that includes go-php, even things that just include it as a dependency. PHP 7.x has been out for a while now, though, so I may just change the default and have PHP 5.x require a tag instead.

[WalkerPnD]

I was not using build tags.
With -tags php7
appears like below.

github.com/deuill/go-php/engine
# github.com/deuill/go-php/engine
In file included from engine/context.go:12:
include/context.h:17:10: fatal error: '_context.h' file not found
#include "_context.h"
         ^
1 error generated.

[deuill]

I believe you may have accidentally removed the following:

#cgo CFLAGS: -Iinclude/php7 -Isrc/php7

Which defines the include paths for the local PHP 7.x headers.

[WalkerPnD]

I did the whole process from downloading the "go-php" library and I've got the same error message.

In file included from engine/context.go:12:
include/context.h:17:10: fatal error: '_context.h' file not found
#include "_context.h"
         ^
1 error generated.

I'm thinking that OS X version of php is very strange because instead of installing in include/php7 dir it's installed in /usr/local/Cellar/php70/7.0.7/include dir (maybe cos the rootless problem?).
And I couldn't find _context.h file in any version of php installed.

[deuill]

The _context.h file is a local include here, and does not belong to PHP itself, hence why you need those relative paths I commented on above, in addition to the absolute paths to /usr/local/Cellar/php70/7.0.7/include etc.

I'll see if I can find a MacOS machine to test support on.

[WalkerPnD]

I think I got that part.. Now I have another message.
Let me organize what I've done until now.

At first when I just finished to download and do go build -tags php7 I get this message.

# github.com/deuill/go-php/engine
engine/context.go:11:11: fatal error: 'main/php.h' file not found
 #include <main/php.h>
          ^
1 error generated.

so I change engine/context.go file's import with full path

// #cgo CFLAGS: -I/usr/local/Cellar/php70/7.0.7/include/php -I/usr/local/Cellar/php70/7.0.7/include/php/main -I/usr/local/Cellar/php70/7.0.7/include/php/TSRM
// #cgo CFLAGS: -I/usr/local/Cellar/php70/7.0.7/include/php/Zend -Iinclude

The new part is here. this is the new message I've got.

github.com/deuill/go-php/engine

[deuill]

You're getting there! Final piece (hopefully) would require that you go into php7.go and change that line to this (or similar):

// #cgo LDFLAGS: -L/usr/local/Cellar/php70/7.0.7/lib -lphp7

I assume that's where Homebrew installs the PHP libraries.

[WalkerPnD]

The lib path is that you wrote.
I'm tried adding the path but doesn't compile. so I tried changing the depth of the path like
<path from root>/lib, <path from root>/lib/php, <path from root>/lib/php/build but still getting the same message.

[deuill]

It may be that Homebrew installs the libraries as libphp.so and not libphp7.so. Check the relevant folders and see what the name of the .so libraries are. The convention is, a -lphp7 declaration corresponds to a file named libphp7.so, and so forth.

[WalkerPnD]

inside lib dir looks like this

/lib
└── php
    └── build
        ├── Makefile.global
        ├── acinclude.m4
        ├── config.guess
        ├── config.sub
        ├── libtool.m4
        ├── ltmain.sh
        ├── mkdep.awk
        ├── phpize.m4
        ├── run-tests.php
        ├── scan_makefile_in.awk
        └── shtool

next lib dir there is a libexec dir which contains apache2/libphp7.so
So I tried variations like

// #cgo LDFLAGS: -L/usr/local/Cellar/php70/7.0.7/libexec/ -lphp7
// #cgo LDFLAGS: -L/usr/local/Cellar/php70/7.0.7/libexec/apache2 -lphp7

but results the same.

[deuill]

Bah, how stupid. It appears that Homebrew does not support building PHP as a shared library. I assumed passing the --enable-embed=shared option, which works for the PHP source, would be passed in and the libraries installed correctly; it is not.

These are your choices:

• Fix the Homebrew recipe for php-embed.
• Build and install PHP from source with the above option, in which case you probably don't need the path hacks above. There's probably some tutorial out there to help out.
• Build and develop in a Linux container/VM.

[WalkerPnD]

yah, actually I couldn't notice that. brew didn't give me any feedback..
I don't understand properly about brew.
And I guess docker/VM will not help much. I heard cgo has cross compile difficulty.
I'm going to try compiling from source.

[WalkerPnD]

hi, I built php from source. Now I have embed lib files but still I have a similar message.
I'm thinking to give up and look for another away.

Hi guys, how did you succeed to build PHP from source on OS X with "--enable-embed=shared"? I constantly got bunch of errors like this:

clang: error: ext/date/php_date.o: No such file or directory

Tried different ways but still no luck.

[deuill]

I'm not sure if PHP can be built with Clang. If anything, there's probably documentation out there on how to build.

The real outcome of this is I should probably provide binary packages built against PHP statically, but I need to confirm with the PHP license before I can do that.

[aaxx]

I built with gcc-6 too, there are some problems with .o / .dyld file locations on OS X when building with "--enable-embed=shared" option. It is a known bug at PHP.net, but nobody cares. If you could, please release static binary, because "shared PHP" is quite hard to achieve on OS X.

Thanks a lot for the package though :)

[WalkerPnD]

Hi, I could build PHP on Mac but the problem was to link these files and build with go.
now I'm going to look for a way to link ".so" files. I'm not sure if it's possible but could be another way.
thanks for the help @deuill

[aaxx]

@walker-walks Could you tell how did you compile the PHP in shared mode on OS X, please?

[WalkerPnD]

Hi @aaxx . To be honest I don't remember exactly. I mixed up some tutorials to do that.
This is what I remember.

1. Download PHP source file from the official.

PHP Download

2. configure the make file with build options. like below.

./configure \
  --enable-mod-charset \
  --with-config-file-path=/etc \
  --with-apxs2=/usr/sbin/apxs \
  --disable-cgi \
  --with-libexpat-dir=/usr \
  --with-libxml-dir=/usr \
  --with-openssl \

these options are just an example, for detail you can check here.

PHP Build options

3. after configuring make file you do make, make test and make install.

I think it was something like this.
