Hull users,
I am  configuring  pango cairo with fontconfig using the command
root at gatewya:/usr/local/src/pango-1.29.4#  ./configure
--prefix=$INSTALL_DIR CFLAGS="-O3 -fPIC" --with-x
Error:
hecking for IceConnectionNumber in -lICE... yes
./configure: line 18798: syntax error near unexpected token `FONTCONFIG,'
./configure: line 18798: `PKG_CHECK_MODULES(FONTCONFIG, fontconfig >=
2.5.0, have_fontconfig=true, { $as_echo "$as_me:${as_lineno-$LINENO}:
result: no" >&5'

When i use
#./autgen.sh
