[aarch64-port-dev ] failed to build JDK9

[Tangwei (Euler)]

Hi All,
  I cloned the latest openJDK9 for aarch64 on Ubuntu and failed to configure with following error message.
Anyone knows how to solve this issue? From the message, it suggested to install libfreetype6-dev,
but the library has already been installed.

configure: Could not compile and link with freetype. This might be a 32/64-bit mismatch.
configure: Using FREETYPE_CFLAGS=-I/usr/include/freetype2   and FREETYPE_LIBS=-lfreetype
configure: error: Can not continue without freetype. You might be able to fix this by running 'sudo apt-get install libfreetype6-dev'.
configure exiting with result code 1


Regards!
