下载安装

wget https://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.17.tar.gz

tar -xzvf libiconv-1.17.tar.gz

cd libiconv-1.17

./configure --prefix=/usr/local/libiconv

1.cli模式下安装php8.0

cd /www/server/php/80/src

./configure --with-iconv=/usr/local/bin/

make && make install

php -v

提示安装成功

2.宝塔面板安装

--with-iconv=/usr/local/bin/

#Build complete.

#Don't forget to run 'make test'.

#Installing shared extensions: /www/server/php/80/lib/php/extensions/#no-debug-non-zts-20200930/

提示成功

提示：宝塔安装需要打补丁，否则安装不成功

总结：宝塔php8以上的包里面iconv包出现问题，php8以下版本不影响，以上测试仅支持宝塔面板，如果是第三方集成环境或者php8官方包则不会出现此类问题。
