php-alpineコンテナにxdebugをインストールする時にハマったメモ

Last updated at Posted at 2019-04-15

xdebugをインストールする時に何回もコケたので、その時のエラーも含めて残します。

TL;DR

# apk add autoconf build-base
# pecl install xdebug
# docker-php-ext-enable xdebug

実際のdockerファイルはこちら https://github.com/ucan-lab/docker-laravel5/blob/master/docker/php/Dockerfile

環境

php バージョン

# php -v
PHP 7.3.4 (cli) (built: Apr 10 2019 00:12:43) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.3.4, Copyright (c) 1998-2018 Zend Technologies

xdebug をインストールの実行

xdebug をインストールを試みると Cannot find autoconf エラーが発生しました。

# pecl install xdebug
downloading xdebug-2.7.1.tgz ...
Starting to download xdebug-2.7.1.tgz (230,653 bytes)

Cannot find autoconf. Please check your autoconf installation and the
$PHP_AUTOCONF environment variable. Then, rerun this script.

ERROR: `phpize' failed

autoconf パッケージが見つからないエラーです。

解決策

autoconf をインストールする。

# apk add autoconf
(1/4) Installing m4 (1.4.18-r1)
(2/4) Installing libbz2 (1.0.6-r6)
(3/4) Installing perl (5.26.3-r0)
(4/4) Installing autoconf (2.69-r2)
Executing busybox-1.29.3-r10.trigger
OK: 108 MiB in 48 packages

autoconf をインストールできたので再実行を試みます...。

xdebug インストールの再実行

xdebug をインストールを再度試みると no acceptable C compiler found エラーが発生しました。

ビルドするために必要な gcc g++ make パッケージが足りないエラーです。

解決策1

build-base ビルドのためのグループパッケージが用意されているので、これをインストールします。

# apk add build-base

(2/16) Installing libmagic (5.35-r0)
(3/16) Installing file (5.35-r0)

解決策2

個別にインストールしてもok。インストールするパッケージが少ない分、個別にした方が速い。

# apk add gcc g++ make
(1/4) Installing m4 (1.4.18-r1)
(2/4) Installing libbz2 (1.0.6-r6)
(3/4) Installing perl (5.26.3-r0)
(4/4) Installing autoconf (2.69-r2)
Executing busybox-1.29.3-r10.trigger
OK: 108 MiB in 48 packages

xdebug インストールの再々実行

# pecl install xdebug
downloading xdebug-2.7.1.tgz ...
Starting to download xdebug-2.7.1.tgz (230,653 bytes)

building in /tmp/pear/temp/pear-build-defaultusergcLNNb/xdebug-2.7.1

... 省略 ...

You should add "zend_extension=/usr/local/lib/php/extensions/no-debug-non-zts-20180731/xdebug.so" to php.ini

xdebug のインストールが成功しました😊
