Building PHP From Source

Good afternoon all I am trying to build PHP from source (Git) as I would like to try and help the project out. I downloaded the latest source (master) from github. I ran ./buildconf and then ./configure with the following options ./configure \ --enable-debug \ --enable-zts \ --srcdir=. \ --config-cache \ --prefix=/home/jonny/myphp \ --sbindir=/home/jonny/myphp/bin \ --sysconfdir=/home/jonny/myphp/etc/myphp8 \ --localstatedir=/var \ --with-layout=GNU \ --with-config-file-path=/home/jonny/myphp/etc/myphp8 \ --with-config-file-scan-dir=/home/jonny/myphp/etc/myphp8/conf.d \ --disable-rpath \ --mandir=/home/jonny/myphp/man \ --libdir=/home/jonny/myphp/usr/lib/myphp8 \ --datarootdir=/home/jonny/myphp/usr/share/myphp8 \ --datadir=/home/jonny/myphp/usr/share/myphp8 \ --program-suffix=8.2 \ --includedir=/home/jonny/myphp/usr/include/myphp8 \ --host= \ --enable-cgi \ --enable-fpm \ --with-fpm-user=http \ --with-fpm-group=http \ --enable-embed=shared \ --enable-bcmath=shared \ --enable-calendar=shared \ --enable-exif=shared \ --enable-ftp=shared \ --enable-intl=shared \ --enable-mbstring \ --enable-opcache \ --enable-pcntl \ --enable-phar=shared \ --enable-posix=shared \ --enable-shmop=shared \ --enable-soap=shared \ --enable-sockets=shared \ --enable-sysvmsg=shared \ --enable-sysvsem=shared \ --enable-sysvshm=shared \ --enable-mysqlnd \ --enable-gd=shared \ --with-external-gd \ --with-ffi=shared \ --with-bz2=shared,/usr/ \ --with-curl=shared \ --with-db4=/usr \ --with-enchant=shared,/usr \ --with-gdbm=/usr \ --with-gettext=shared \ --with-gmp=shared \ --with-iconv=shared \ --with-ldap=shared,/usr \ --with-ldap-sasl \ --with-sodium=shared \ --with-mhash \ --with-mysql-sock=/run/mysqld/mysqld.sock \ --with-mysqli=shared,mysqlnd \ --with-openssl=shared \ --with-external-pcre \ --with-pear=/home/jonny/myphp/usr/share/mypear \ --with-pdo-mysql=shared,mysqlnd \ --with-pdo-odbc=shared,unixODBC,/usr \ --with-pdo-pgsql=shared,/usr \ --with-pdo-sqlite=shared,/usr \ --with-pgsql=shared,/usr \ --with-readline=/usr \ --with-snmp=shared,/usr \ --with-sqlite3=shared,/usr \ --with-unixODBC=shared,/usr \ --with-xsl=shared,/usr \ --with-tidy=shared,/usr \ --with-zip=shared \ --with-zlib I get the following output configure: WARNING: you should use --build, --host, --target configure: WARNING: invalid host type: configure: loading cache config.cache checking for grep that handles long lines and -e... /bin/grep checking for egrep... /bin/grep -E checking for a sed that does not truncate output... /bin/sed checking build system type... config.sub: missing argument Try `config.sub --help' for more information. configure: error: /bin/sh ./build/config.sub failed What values should I use for --build, --host and --target? in the ./configure command? I am building on an Intel x86_64 bit platform running Void Linux. The output of uname -a is Linux jrlp02 6.1.18_1 #1 SMP PREEMPT_DYNAMIC Mon Mar 13 13:42:23 UTC 2023 x86_64 GNU/Linux Many thanks J
