Hi, Today I downloaded a fresh CVS (fresh checkout, no update) and tryied to build it under Linux, but failed at compiling dpp.c because it cannot find ecl/gmp.h (included from config.h). I configured it with: ./configure --prefix=/bla/bla/ecl --exec-prefix=/bla/bla/ecl/LINUX --with-tcp --without-system-gmp Michael.
