Recently I had a problem while compiling php and apache to a cpanel server and while looking at the easyapache log I saw the following:
ext/iconv/iconv.c:1128: undefined reference to `libiconv’

The reason could either be glibc-common and glibc-devel packages. So I have force fully reinstalled the packages and put the proper iconv binary back on the system and the proper iconv headers.
root@server [~]# rpm -Uvh –nodeps –force glibc-common.rpm
root@server [~]# rpm -Uvh –nodeps –force glibc-devel.rpm
You should now be able to recompile the php without any issues.
undefined reference to `libiconv_open`
