Yes thank you for this workaround but ld didn't like it: /usr/bin/ld: unrecognized option '-L/usr/lib/gcc-lib/i586-mandrake-linux-gnu/2.96/../../..' /usr/bin/ld: use the --help option for usage information collect2: ld returned 1 exit status Without quote, expression links good so ... 1/ I think there isn't any options in automake / libtool for do what I want. 2/ -whole-archive flag is os dependant, and already defined in libtool, I must use it 3/ I must do an automake / libtool patch that: a/ In automake, define something in automake template, something like mybinaries_WHOLE_LIB = myfirstlib.la mysecondlib.la This variable isn't in use without --disable-shared flag b/ If --disable-shared option of configure is in use, automake must remove libs that is two times on link command and keep only this with whole-archive flag. c/ Add a -whole-archive options in libtool that use os specific option for link a library into a binarie What you think of this ? -- Alain BARBET
