Hi there, we are currently running Zabbix server 5.2 on Solaris 10 Sparc with MySQL 5.5.27. We want to upgrade to Zabbix server 5.2 using PHP 7.4

I'm struggling currently to configure and build PHP 7.4, please see below:

/app/INSTALL_FILES/php-7.4.13

./configure --with-apxs2=/usr/apache2/bin/apxs --with-zlib --disable-ipv6 --with-pear --with-openssl --enable-bcmath --enable-ctype --enable-sockets --enable-mbstring --with-gettext --prefix=/usr/php

Configuring extensions
checking io.h usability... no
checking io.h presence... no
checking for io.h... no
checking for strtoll... yes
checking for atoll... yes
checking whether to build with LIBXML support... yes
checking for libxml-2.0 >= 2.7.6... no
configure: error: Package requirements (libxml-2.0 >= 2.7.6) were not met:

sh: gnome-config: not found
No package 'libxml-2.0' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables LIBXML_CFLAGS
and LIBXML_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

any help would be much appreciated, we have been using the PHP website with no success.
