Follow-up Comment #2, sr #110530 (project autoconf): 1. We currently don't support *any* use of -Werror or -Werror=whatever in configure scripts. There are lots and lots of places where autoconf's test programs trigger warnings, especially with newer compilers. We *want* to fix all of those eventually but we have *no* developers right now, so "eventually" might be a very long time.
The recommended way to use -Werror with autotools is with an AC_ARG_ENABLE construct that *optionally* adds -Werror to a dedicated AC_SUBST variable that is then added to AM_CFLAGS in Makefile.am (or equivalent if you're not using automake). 2. That said, HAVE_STRING_H should have been defined automatically. Could you please cut down dfu-programmer's configure.ac to the smallest thing you can manage that still reproduces the issue, and attach that file here? Please also make it self-contained -- inline any definitions from aclocal.m4 that are needed. _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/support/?110530> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
