I am always waiting for your answer.thanks

Make sure not to have libiconv installed via homebrew or MacPorts. If you have it, uninstall it, make distclean, configure, and make.

I user the command "port installed" in terminal.app. it showe me libiconv @1.14_0+universal (active).
when i use sudo port uninstall libiconv @1.14_0+universal in terminal.app. it warn me that


WARNING: Improper use of the sudo command could lead to data loss
or the deletion of important system files. Please double-check your
typing when using sudo. Type "man sudo" for more information.

why do i need to uninstall libiconv? is it will be ok?

The warning is quite clear. You need to know if its ok to uninstall libiconv (macports might warn that another package depends on the libiconv package, then you need to check if you actually need this package).

Maybe you can also proceed by not touching the macports installation, but instead clear your environment from macports entries. See the compilation instructions for that, which you already linked to.

As what you said,when i use the command "port uninstall libiconv@1.14_0+universal".
it showed me as follows:

Could you show me how to clear my environment from macports entries. I can not find the compilation instructions for that.Thank you very much.

Please see the instructions in the wiki: https://wiki.videolan.org/OSXCompile/#3 ... s_and_PATH

You need to execute these commands in terminal before _all_ other compilation steps.
