2010年09月05日 setting of vim to edit utf-8

_ setting of vim to edit utf-8

基本的にcharctersetは未だにeucでやっている。

$ echo $LANG
ja_JP.eucJP

でも、utf-8のファイルを編集したいこともたまに出て来るようになった。

~/.exrc-utf8を作って

$ cat .exrc-utf8
let &termencoding = &encoding
set encoding=utf-8
set fileencodings=utf-8,euc-jp,cp932,default,latin

viutf8というaliasを定義している。

$ alias viutf8
alias viutf8='/usr/bin/vim -u ~/.exrc-utf8'

2021年09月05日 Building ClamAV-0.104.0 on Slackware-14.2

_ Slackware-14.2でClamAV-0.104.0をビルドする

Slackware-14.2でClamAV-0.103.3からClamAV-0.104.0にバージョンアップしたのだけれど、新しめなcmakeやら新たなライブラリやらが必要になっていた。

cmake-3.19.6を/optにインストール

オリジナルのcmake-3.5.2では古すぎて、ClamAV-0.104.0はビルド出来ない。

tar xvf cmake-202x.tar.gz
mv cmake-3.19.6.tar.gz cmake-202x/
cd cmake-202x
sudo sh cmake-202x.SlackBuild
sudo installpkg /tmp/cmake-202x-3.19.6-i586-1_SBo.tgz

これで、/opt/cmake-202x/以下にインストールされる。

check-0.15.2のインストール

ClamAV-0.104.0のビルドには、libcheckとやらが必要とのこと...

tar xvf check.tar.gz
mv check-0.15.2.tar.gz check/
cd check
sudo sh check.SlackBuild
sudo installpkg /tmp/check-0.15.2-i586-1_SBo.tgz

python-3.7.2のインストール

Python3も必要...

tar xvf python3.tar.gz
mv Python-3.7.2.tar.xz python3/
cd python3
sudo sh python3.SlackBuild
sudo installpkg /tmp/python3-3.7.2-i586-1_SBo.tgz

ようやくClamAV-0.104.0のビルド

tar xvf clamav-0.104.0.tar.gz
cd clamav-0.104.0
mkdir build
cd build
PATH=/opt/cmake-202x/bin:${PATH} cmake ..
make
sudo make install
