Compilation issue on ppa:ondrej/php

[MichaelNino]

Hi,

I'm very excited about the possibilities for this extension!!! :-)

Describe the bug

Should I build against staging branch? When I built against master it didn't complete.

Steps to reproduce

Followed installation instructions in README for staging branch

Expected behavior

php examples/simple.php didn't run

Actual behavior

/home/michael/php/php-ext-wasm# php examples/simple.php

Hello,

Did you run composer install before?
Also, it seems the extension isn't properly installed, or basically not enabled. Try with php -d extension=wasm examples/simple.php maybe.

[Hywan]

Also, you should use the master branch, not staging. This one is for testing purposes.

[MichaelNino]

When I built "staging" branch, I did run composer install. I don't get that far with "master" branch. Please note the following:

just v0.5.1
rustc 1.39.0
php 7.2.24-0ubuntu0.18.04.1
composer 1.9.0

So I did what you recommended. I checked out "master" and the provided following output is from just build. The error is Makefile:194: recipe for target 'wasm.lo' failed.

> git clone https://github.com/wasmerio/php-ext-wasm.git
> cd php-ext-wasm

[Hywan]

I think libtool is failing because of -DPIC. Can you run the command without it?

In general, can you try the following commands:

export PATH="$HOME/.cargo/bin:$PATH"
export CXX="gcc"
EXTENSION="$HOME/project/src"
cd $EXTENSION
PHP_PREFIX=$(php-config --prefix)
PHP_PREFIX_BIN=$PHP_PREFIX/bin

Does it work?

[crevillo]

hello. i'm more or less in same situation. executing the commands you suggest, i still get same error as @MichaelNino . let me know if i can help with more info.

edit: maybe the problem is different for me. this is the output i get

[MichaelNino]

The reason why both @crevillo and myself are both failing at: #include "php.h" is because the include path in your shell script @Hywan isn't finding the PHP source code our location that your source code is located. I'm running Ubuntu 18.04 and my source is installed at: /usr/include/php/20170718 because my repository is at: ppa:ondrej/php.

I'm not a C/C++ programmer but it would be helpful if you could update your shell script so that it is more configurable. I could probably wade through it and figure it out but I'm having surgery in a couple of days and didn't want this ticket to get stale.

Thanks for your assistance @Hywan!

[Hywan]

If you see php-config and if php-config --prefix returns a valid path for you, I don't see why you should have a compilation problem with the commands above. Can you check that please?

[crevillo]

still no luck. i have a sh script right now with this content

Hey @Hywan php-config --prefix returns "/usr". However php.h is located in "/usr/include/php/20170718/main/php.h". This is why the shell script variable PHP_PREFIX and EXTENSION cannot be used to find "php.h" isn't not located underneath "php-ext-wasm" source tree. Make sense?

[crevillo]

hello. it is working for now after following this other issue #93

the line recommended by @Hywan there does the trick. i thought it was merged in the master branch, but it isn't, right?

[Hywan]

@crevillo I was about to point #93 to you. Wasmer 0.11 has been released and it contains the bug fix. I'll update the master branch of php-ext-wasm today to include the new version of Wasmer.

[Hywan]

@crevillo Done, see #98.

[Hywan]

@MichaelNino I'm not sure #98 will be able to fix your issue, but can you retry with the last shell commands I provided in #97 (comment), and tell me the exact output please.

Normally, php-config --prefix returns the root that has an acces to all PHP directories, such as include/php/20170718/.

[MichaelNino]

@Hywan I used Ubuntu on Windows Subsystem to verify that php-ext-wasm installs properly. I used the Ubuntu repository to install php7.2 however the Digital Ocean server that is experiencing the issue uses the ppa:ondrej/php repository I indicated earlier. For now, I will use the Ubuntu repository however the ppa:ondrej/php repository as you may already know is very popular and used quite often for a variety of reasons including but not limited to concurrent versions of PHP.

Thanks for your assistance. I will be evaluating the extension. There so many opportunities for inter-op and integration! Thanks again! :-)

[Hywan]

I'll try to run a test on ppa:ondrej/php. Thanks for your support!
