----------------------------------------------------------------------
Libraries have been installed in:
/usr/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,--rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

who know what this means?thks

Fontconfig expects FreeType to provide FT_Select_Size and your FreeTtype isn't. It means the version of FreeType you have installed is either too old or too new for FontConfig-2.5.93 or your FreeType is broken.

BTW, if you're going to string commands use && instead of ;. The && prevents the next command from executing if the previous command exits with other than a 0 exit code. In this case you've installed an incomplete fontconfig by using ;. Of course you're also configuring and compiling as root which is unnecessary.

ok,thanks
just the problem

This thread helped me too

me too. In my case freetype update was required. Just downloaded source, compiled and done.
