AWS / PHP / Python ちょいメモ

amazon web service , PHP, Python を使ったときのメモ。日本語でググってもわからなかった事を中心に。

Mac に pythonz 入れる時の OPTION 設定

以前書いた pythonz on Mac の手順が、通用しないようだったので修正方法を探ってみました。

結果としては、pythonz で install する時にオプション設定をすることで解決しました。

MacOS ver 10.11.6 (OS X El Capitan)
/usr/local/opt/openssl 1.0.2j (by homebrew)
pythonz 2.0.1
導入する python 3.5.2

変わってたところ : OpenSSL on brew

以前は --force 使って手順進めてましたが、現在のバージョンでは、こんなメッセージがでて link できません。
代わりにコンパイラにパスを渡せと。

$ brew link openssl --force
Warning: Refusing to link: openssl
Linking keg-only openssl means you may end up linking against the insecure,
deprecated system OpenSSL while using the headers from Homebrew's openssl.
Instead, pass the full include/library paths to your compiler e.g.:
-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib

pythonz にパスを渡すには

pythonz install の オプションに "-C CONFIGURE_OPTIONS, --configure=CONFIGURE_OPTIONS" がありましたので、こちらを利用します。後述するように 導入するPythonの configure オプションを確認して、次のように引数を設定しました。

$ pythonz install --configure='LDFLAGS="-L/usr/local/opt/openssl/lib" CFLAGS="-I/usr/local/opt/openssl/include"' 3.5.2

pythonz の install オプションのヘルプ

$ pythonz install -h

-h, --help show this help message and exit
-t TYPE, --type=TYPE Type of Python version: cpython, stackless, pypy,
pypy3 or jython.

Python 3.5.2 configure の ヘルプ

$ ./configure --help
`configure' configures python 3.5 to adapt to many kinds of systems.

Usage: ./configure [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
-h, --help display this help and exit
--help=short display options specific to this package
--help=recursive display the short help of all the included packages
-V, --version display version information and exit
-q, --quiet, --silent do not print `checking ...' messages
--cache-file=FILE cache test results in FILE [disabled]
-C, --config-cache alias for `--cache-file=config.cache'
-n, --no-create do not create output files
--srcdir=DIR find the sources in DIR [configure dir or `..']

Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[/usr/local]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]

By default, `make install' will install all the files in
`/usr/local/bin', `/usr/local/lib' etc. You can specify
an installation prefix other than `/usr/local' using `--prefix',
for instance `--prefix=$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--libdir=DIR object code libraries [EPREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--oldincludedir=DIR C header files for non-gcc [/usr/include]
--datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
--datadir=DIR read-only architecture-independent data [DATAROOTDIR]
--infodir=DIR info documentation [DATAROOTDIR/info]
--localedir=DIR locale-dependent data [DATAROOTDIR/locale]
--mandir=DIR man documentation [DATAROOTDIR/man]
--docdir=DIR documentation root [DATAROOTDIR/doc/python]
--htmldir=DIR html documentation [DOCDIR]
--dvidir=DIR dvi documentation [DOCDIR]
--pdfdir=DIR pdf documentation [DOCDIR]
--psdir=DIR ps documentation [DOCDIR]

System types:
--build=BUILD configure for building on BUILD [guessed]
--host=HOST cross-compile to build programs to run on HOST [BUILD]

Some influential environment variables:
MACHDEP name for machine-dependent library files
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L if you have libraries in a
nonstandard directory
LIBS libraries to pass to the linker, e.g. -l
CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I if
you have headers in a nonstandard directory
CPP C preprocessor
PKG_CONFIG path to pkg-config utility
PKG_CONFIG_PATH
directories to add to pkg-config's search path
PKG_CONFIG_LIBDIR
path overriding pkg-config's built-in search path

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

確認方法

導入したpythonがアクティブになってる際に which pip などとして動作する pip を確認します。導入した python と同じフォルダに同梱されてる pip が動いていればOK。

3.4以降は pip は標準のようですし、pythonz で導入したpython は、バージョンによらず pip , setuptools は導入するように作られてるようなので、もしOSオリジナルのpipが動作していれば、オカシイなぁと思って再installという流れでしょうか。

トラブルシュート

pythonz で入れた python の動作が何やら怪しい場合には、こちらをチェック。SSLが必要な設定がスキップされてるときには、次のように記録されていました。

~/.pythonz/log/build.log

if test "xupgrade" != "xno" ; then \
case upgrade in \
upgrade) ensurepip="--upgrade" ;; \
install|*) ensurepip="" ;; \
esac; \
./python.exe -E -m ensurepip \
$ensurepip --root=/ ; \
fi
Ignoring ensurepip failure: pip 8.1.1 requires SSL/TLS

ちなみに導入が成功した場合のログ。pip も setuptools も導入が成功しています。

if test "xupgrade" != "xno" ; then \
case upgrade in \
upgrade) ensurepip="--upgrade" ;; \
install|*) ensurepip="" ;; \
esac; \
./python.exe -E -m ensurepip \
$ensurepip --root=/ ; \
fi
