I think this is for scheme... I have gcc 3.4.1, and I have -Wall Cflag.. Reproducible: Always Steps to Reproduce: 1. 2. 3. Actual Results: Some deprecated features have been used. Set the environment variable GUILE_WARN_DEPRECATED to "detailed" and rerun the program to get more information. Set it to "no" to suppress this message. if /bin/sh ../libtool --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I.. -O2 -Wall -Wno-uninitialized -Werror -g -I ../g-wrap -I/usr/include/glib-1.2 -I/usr/lib/glib/include -I/usr/include/glib-1.2 -I/usr/lib/glib/include -march=athlon-xp -pipe -fomit-frame-pointer -Wall -MT gw-test-glib.lo -MD -MP -MF ".deps/gw-test-glib.Tpo" \ -c -o gw-test-glib.lo `test -f 'gw-test-glib.c' || echo './'`gw-test-glib.c; \ then mv ".deps/gw-test-glib.Tpo" ".deps/gw-test-glib.Plo"; \ else rm -f ".deps/gw-test-glib.Tpo"; exit 1; \ fi mkdir .libs gcc -DHAVE_CONFIG_H -I. -I. -I.. -O2 -Wall -Wno-uninitialized -Werror -g -I ../g-wrap -I/usr/include/glib-1.2 -I/usr/lib/glib/include -I/usr/include/glib-1.2 -I/usr/lib/glib/include -march=athlon-xp -pipe -fomit-frame-pointer -Wall -MT gw-test-glib.lo -MD -MP -MF .deps/gw-test-glib.Tpo -c gw-test-glib.c -fPIC -DPIC -o .libs/gw-test-glib.lo gw-test-glib.c: In function `gw__tmp18_gw_test_gw_standard_echo_gchars_caller_owned_wrapper': gw-test-glib.c:159: warning: 'gw__c_arg0' might be used uninitialized in this function make[2]: *** [gw-test-glib.lo] Error 1 make[2]: Leaving directory `/var/tmp/portage/g-wrap-1.3.4-r1/work/g-wrap-1.3.4/test' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/var/tmp/portage/g-wrap-1.3.4-r1/work/g-wrap-1.3.4' make: *** [all] Error 2 !!!

still happening, I also use the -Wall cflag... to catch buggy code I think uninitialized use gets caught by that... upstream?
It compiled without the -Wall This ebuild needs to filter -Wall out... or.. better yet, upstream needs to fix it... ... or make sure the -Wno-uninitialized comes after the -Wall This is a bug, that is just being ignored / worked arround by the -Wno-uninitialized CFLAG I don't think that this is a gcc-porting problem, assign to whom? I looked for other assignies of deb-libs.. but I didn't see any obvious email to add to the cc-list
Don't put -Wall in your cflags.
reopen
