Hello, I am trying to build the source code from git repository but came across this error - ./configure: line 7227: syntax error near unexpected token `0.9.0' ./configure: line 7227: `PKG_PROG_PKG_CONFIG(0.9.0)' I did lookup for "syntax error near unexpected token" with "PKG_PROG_PKG_CONFIG" on web but did not find a definite or helpful solution. I tried reading output and found this (below) but mostly I don't know how to relate what is in the manual to the problem I am facing. autoreconf: Entering directory `.' autoreconf: running: true --force autoreconf: running: aclocal -I m4 --force m4/pkg.m4:4: warning: underquoted definition of PKG_CHECK_MODULES m4/pkg.m4:4: run info Automake 'Extending aclocal' m4/pkg.m4:4: or see http://www.gnu.org/software/automake/manual/automake.html#Extending-aclocal Can I receive some help? A pointer to solution or something like that that would transform dont-know the-problem to a large homework would also suffice. :) I have attached output of configure and bootstrap. Sincerely, Rishabh
