include - Where does autoconf's AC_CHECK_HEADERS verify the header files? -

-

i having trouble compiling 1 of open source libraries (libopekele openid lib).

the problem don't have sudo access on system need compile this.

ran configure. complained of missing htmltidy lib. installed htmltidy @ non-standard path /home/geekgod (as dont have access /usr , /usr/local)

now problem how make configure script of libopekele pick the headers /home/geekgod/include.

poking configure.ac script of libopkele,

it using ac_check_headers search tidy.h or tidy/tidy.h pretty sure looking these @ standard location (/usr/include) how add /home/geekgod standard include dir

try this:

./configure cppflags=-i/home/geekgod/include --prefix=... --etc
