WordPressのinstallにはPHP-7.4が必要らしい。
https://seesaawiki.jp/lifewithslackarmzaurus_15_0/d/WordPress

PHP-7.4.11：
先に古いVerが入っていない事を確認した。
$ ll /var/log/packages/*php*
ls: cannot access ‘/var/log/packages/*php*’: No such file or directory
何故か、slackbuilds.orgにphp-x.yがない。https://slackbuilds.org/slackbuilds/14.2/network/
currentを参考にする。
(http://ftp.kddilabs.jp/Linux/distributions/Slackware/slackware-current/source/n/php/php.SlackBuild を参考に、)

\# If the variable PRINT_PACKAGE_NAME is set, then this script will report what

\# could be useful to other scripts.
\$ if [ ! -z “${PRINT_PACKAGE_NAME}” ]; then
\ echo “$PKGNAM-$VERSION-$ARCH-$BUILD.txz”
\ exit 0
\fi
(PRINT_PACKAGE_NAMEて何だ。Slack特有らしい。どうやら依存するpkgのnameやverを取ってくる
\ためだけにあるらしい。今回は無効。例、aaa_terminfo.SlackBuild -> ncurses.SlackBuild：
\VERSION=${VERSION:-$(PRINT_PACKAGE_NAME=yes ./ncurses.SlackBuild | cut -f 2 -d -)}
\よく忘れるVERSION:-とはVERSIONに値がsetされていなければsetするという意味)
$ NUMJOBS=${NUMJOBS:-” -j$(expr $(nproc) + 1) “}
(となっているが、-1の間違いではないか? あと、以下でも行けた)
$ NUMJOBS=${NUMJOBS:-” -j$(echo “$(nproc) + 1” | bc) “} ; echo $NUMJOBS

\# Look for Kerberos on the machine and in any precompiled c-client.a:
$ ls -l {,/usr}/lib/libkrb*
(無い。kerberosを先に入れた https://seesaawiki.jp/lifewithslackarmzaurus_15_0/d/krb5%a4%f2%c6%fe%a4%ec%a4%eb )
\# Remove the c-client library if it doesn’t contain Kerberos support:
\if ! grep -q krb5_ /usr/local/lib/c-client/lib/c-client.a 2> /dev/null ; then
\ rm -rf /usr/local/lib/c-client
\fi
(/usr/local/lib/c-clientは最初から無い。ls -d /usr/lib/*/ にも無い)
\# we need to compile alpine to get c-client.a for IMAP support:
$ ls -l /usr/local/lib/c-client/lib/c-client.a
ls: cannot access ‘/usr/local/lib/c-client/lib/c-client.a’: No such file or directory
(alpine.SlackBuildを実行する代わりに、alpine.tgzを展開してコピーする。currentではなく
\14.2にもあるのでそっちを使う。と思ったが、alpine kerberos、でググろうとすると、alpine
\ linux kerberos client が補完されたりする。kerberosのヘッダーをincludeしてるのか?
\念のためにmakeするか)
そっちを先にmakeする。
$ ( cd ~/alpine-2.25/imap/c-client
\ sudo strip -g c-client.a
\ sudo mkdir -p /usr/local/lib/c-client/lib
\ sudo cp c-client.a /usr/local/lib/c-client/lib/
\ sudo mkdir -p /usr/local/lib/c-client/include
\ sudo cp *.h /usr/local/lib/c-client/include
\)
\# Set Kerberos build option:
\if /bin/ls /lib/libkrb5.so.? 1> /dev/null 2> /dev/null ; then
\ KRB5_OPTION=”–with-kerberos”
\else
\ unset KRB5_OPTION
\fi
(kerberosは既に入っているのでconfig_optionに –with-kerberos を追加する)
