Hello, Encounter a strange behaviour with autoconf. I do not understand why all the compiled *.o files are prefixed with target-xxx.o. Below an example ... have no progname yet for my executable hence let's call it main for now ... bin_PROGRAMS = main main_SOURCES = obj1.cc obj2.cc Executable is OK but have no clue why I have something like this at the end ? ... src/main-obj1.o src/main-obj2.o Thanks for your help ... -V
