app-mobilephone/obexftp-0.21 fails when compiling with --as-needed LDFLAG on. When not using --as-needed, compiles and works fine. obexftp-0.19-r1 has same problems. While I'am not a dev, I'll try to investigate it deeper according to Gentoo --as-needed introduction and fixing guide. emerge -pvt obexftp [ebuild R ] app-mobilephone/obexftp-0.21 USE="bluetooth nls perl python -debug -swig -tcl" 0 kB make[2]: Entering directory `/var/tmp/portage/app-mobilephone/obexftp-0.21/work/obexftp-0.21/apps' if i686-pc-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I. -I.. -I.. -I../includes -O2 -march=pentium3 -pipe -fomit-frame-pointer -fno-strict-aliasing -W -Wundef -Wmissing-declarations -Wmissing-prototypes -Wall -MT obexftp.o -MD -MP -MF ".deps/obexftp.Tpo" -c -o obexftp.o obexftp.c; \ then mv -f ".deps/obexftp.Tpo" ".deps/obexftp.Po"; else rm -f ".deps/obexftp.Tpo"; exit 1; fi obexftp.c:134: warning: pointer targets in initialization differ in signedness obexftp.c:135: warning: pointer targets in initialization differ in signedness obexftp.c:136: warning: pointer targets in initialization differ in signedness obexftp.c:184: warning: pointer targets in initialization differ in signedness obexftp.c: In function ‘cli_connect_uuid’: obexftp.c:214: warning: pointer targets in passing argument 4 of ‘obexftp_connect_uuid’ differ in signedness obexftp.c: In function ‘probe_device’: obexftp.c:327: warning: pointer targets in passing argument 1 of ‘probe_device_uuid’ differ in signedness obexftp.c:330: warning: pointer targets in passing argument 1 of ‘probe_device_uuid’ differ in signedness if i686-pc-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I. -I.. -I.. -I../includes -O2 -march=pentium3 -pipe -fomit-frame-pointer -fno-strict-aliasing -W -Wundef -Wmissing-declarations -Wmissing-prototypes -Wall -MT bt_discovery.o -MD -MP -MF ".deps/bt_discovery.Tpo" -c -o bt_discovery.o bt_discovery.c; \ then mv -f ".deps/bt_discovery.Tpo" ".deps/bt_discovery.Po"; else rm -f ".deps/bt_discovery.Tpo"; exit 1; fi /bin/sh ../libtool --tag=CC --mode=link i686-pc-linux-gnu-gcc -O2 -march=pentium3 -pipe -fomit-frame-pointer -fno-strict-aliasing -W -Wundef -Wmissing-declarations -Wmissing-prototypes -Wall -Wl,-O1 -Wl,--as-needed -o obexftp obexftp.o bt_discovery.o ../obexftp/libobexftp.la ../multicobex/libmulticobex.la ../bfb/libbfb.la -lopenobex -lbluetooth -lusb mkdir .libs i686-pc-linux-gnu-gcc -O2 -march=pentium3 -pipe -fomit-frame-pointer -fno-strict-aliasing -W -Wundef -Wmissing-declarations -Wmissing-prototypes -Wall -Wl,-O1 -Wl,--as-needed -o .libs/obexftp obexftp.o bt_discovery.o ../obexftp/.libs/libobexftp.so ../multicobex/.libs/libmulticobex.so ../bfb/.libs/libbfb.so /usr/lib/libopenobex.so /usr/lib/libbluetooth.so /usr/lib/libusb.so ../obexftp/.libs/libobexftp.so: undefined reference to `cobex_ctrans' collect2: ld returned 1 exit status make[2]: *** [obexftp] Error 1 make[2]: Leaving directory `/var/tmp/portage/app-mobilephone/obexftp-0.21/work/obexftp-0.21/apps' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/var/tmp/portage/app-mobilephone/obexftp-0.21/work/obexftp-0.21' make: *** [all] Error 2 !!!

I always verify my ebuilds with --as-needed. I can't reproduce it, even if I set your USE flags.
Created attachment 117579 [details, diff] my patch that worked for me I've found out that libobexftp.so should be linked against another 2 libs from this package and possibly against openobex. (in order to build with --as-needed) Patch rationale: The LDADD in patched Makefile.am is ingnored in generated Makefile.in and Makefile. I just took the 3 libs and added them into libobexftp_la_LIBADD, as automake info page suggests. One weird thing is that you cannont reproduce. I'll try to attract more people to test it. (it could be my misconfiguration, but i can't think of any possible cause)
Created attachment 117583 [details, diff] obexftp-0.21-as-needed.patch @OPENOBEX_LIBS@ is not needed, checked. Other 2 are, or linking of obexftp binary fails with unresolved symbols. Fix patch name.

According to the failing linking command, parameter ../obexftp/.libs/libobexftp.so (the lib that requires cobex_ctrans symbol) is before ../multicobex/.libs/libmulticobex.so (the lib that defines cobex_ctrans). Since libmulticobex.so shouldn't be discarded by --as-needed because one obj/lib file passed before it require one of its symbols. Please check that cobex_ctrans is really defined in libmulticobex.so by running the following command: mrness@alin /var/tmp/portage/app-mobilephone/obexftp-0.21/work/obexftp-0.21/multicobex/.libs $ objdump --dynamic-syms libmulticobex.so | grep cobex_ctrans 0000000000000d90 g DF .text 0000000000000085 Base cobex_ctrans

I tried to reproduce it witout -Wl,-O1, but it failed with the same error. > Please check that cobex_ctrans is really defined in libmulticobex.so by running > the following command: > mrness@alin > /var/tmp/portage/app-mobilephone/obexftp-0.21/work/obexftp-0.21/multicobex/.libs > $ objdump --dynamic-syms libmulticobex.so | grep cobex_ctrans > 0000000000000d90 g DF .text 0000000000000085 Base cobex_ctrans > nb-matej /var/tmp/portage/app-mobilephone/obexftp-0.21/work/obexftp-0.21 # objdump --dynamic-syms multicobex/.libs/libmulticobex.so | grep cobex_ctrans 000009d0 g DF .text 0000009d Base cobex_ctrans nb-matej /var/tmp/portage/app-mobilephone/obexftp-0.21/work/obexftp-0.21 # objdump --dynamic-syms obexftp/.libs/libobexftp.so | grep cobex_ctrans 00000000 D *UND* 00000000 cobex_ctrans Which looks correct to me. Looks to me that you are on amd64. Maybe x86-specific bug?

Now I don't understand why I cannot reproduce. It must be another symbol from libmulticobex.so that keep it from being discarded (at least for me). Your patch has been added to obexftp-0.21 (no revision bump). Thanks!
Thank you for your great work!
Ah, reopening, sorry. The patch I posted only solved build of obexftp, not all dynamic lib dependencies. It is reproducible (whith the current patch in portage): LDFLAGS="-Wl,--as-needed" emerge obexftp obexfs obexfs executable could not be linked, due to unresolved symbols in libobexftp.so, and due to unresolved symbols in libmulticobex.so Following patch will fix this once for all.
Created attachment 117733 [details, diff] obexftp-0.21-as-needed.patch This patch pulls all dependencies to libobexftp.so and libmulticobex.so. These dependencies were somehow mentioned in original Makefile.am's, but not used in build. (only @USB_LIBS@ is discarded by this patch, because it is no longer used) Please trash my old patch and replace it witch this one. Sorry for this inconvenience.
Upstream went the same way, so it should not be a problem, and will be fixed in next version. http://dev.zuckschwerdt.org/obexftp/changeset?new=trunk%2Fobexftp%2FMakefile.am%40114&old=trunk%2Fobexftp%2FMakefile.am%40112
done. thanks!
