Hi, I have been trying to disable the -g flag that autoconf uses when compiling my GNU project. I have tried --enable-debug=no --disable-debug and none works. I have had a look at google and some questions but no response... Can you help me? my configure.ac is: AC_INIT AM_CONFIG_HEADER(config.h) AM_INIT_AUTOMAKE(Xmipp,0.9) AC_PROG_LIBTOOL AC_PROG_CC AC_PROG_CPP AC_PROG_CXX AC_PROG_MAKE_SET AC_PROG_INSTALL AC_LANG(C++) ... All the next just checks for external libraries. Cheers,
