Good morning autoconf community, I am a newbie to autoconf and while I have made some good progress I am hitting a road block. I am taking this project from someone else and trying to use autoconf to package it rather than the manual approach they had. I have created my makefiles and configure.ac... I have read in the tutorial that FCFLAG had to be set to -g (unless it is g77).. Well I need to create *.mod and *.o so I need another set of flags..... if I ran configure this way: ./configure FC=ifort FC_FLAGS="-c -O2 -convert big_endian -free -assume byterecl" it does print out: ========================================= compilation environment variables: FC: ifort FC_FLAGS: -c -O2 -convert big_endian -free -assume byterecl ========================================= but if I check the value of FCFLAG in the created Makefile it says -g only.... so when I run make it tries ifort -g -o Type_Kinds Type_Kinds.o while I want ifort -c -O2 -convert big_endian -free -assume byterecl Type_Kinds.f90 In my Makefile.am I have entries such as:(there are many more like that) bin_PROGRAMS = Type_Kinds Type_Kinds_SOURCES = Type_Kinds.f90 ... is that wrong for modules? I tried those macro too AC_PROG_FC_C_O AC_FC_MAIN in my configure.ac to try telling it it didn't have a main (I just want modules), but no luck.... (Please bear with me as I am new to Fortran too... ) Can anyone shed some light on the situation?
