The problem is with OLD ubuntu releases (12.04 e.g.). With newer ubuntu releases the static linking can be safely dropped (at least for what concernes the building phase).
If that one was a workaround for older gcc version I think this is time to drop it. (even because it was working for really older gcc versions, stopped working for the middle gcc version and now works again) the log from the fail is this one make[2]: Entering directory `/build/buildd/boinc-7.2.0~nightly1~~git20130620+r19549/samples/sleeper' g++ -g -O2 -fPIE -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security -Werror=format-security -Wall -g -I../.. -I../../lib -I../../api -L../../api -L../../lib -L. -D_FORTIFY_SOURCE=2 -c -o sleeper.o sleeper.cpp In file included from ../../lib/miofile.h:27:0, from ../../lib/hostinfo.h:31, from ../../lib/app_ipc.h:27, from ../../api/boinc_api.h:26, from sleeper.cpp:23: ../../lib/mfile.h:43:9: note: the mangling of 'va_list' has changed in GCC 4.4 ln -s `g++ -print-file-name=libstdc++.a` g++ -g -O2 -fPIE -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security -Werror=format-security -Wall -g -I../.. -I../../lib -I../../api -L../../api -L../../lib -L. -D_FORTIFY_SOURCE=2 -Wl,-Bsymbolic-functions -fPIE -pie -Wl,-z,relro -Wl,-z,now -Wl,--no-add-needed -o sleeper sleeper.o libstdc++.a -pthread -lboinc_api -lboinc /usr/bin/ld: ./libstdc++.a(functexcept.o): relocation R_ARM_THM_MOVW_ABS_NC against `typeinfo for std::bad_exception' can not be used when making a shared object; recompile with -fPIC ./libstdc++.a: could not read symbols: Bad value collect2: ld returned 1 exit status make[2]: *** [sleeper] Error 1 make[2]: Leaving directory `/build/buildd/boinc-7.2.0~nightly1~~git20130620+r19549/samples/sleeper' make[1]: *** [override_dh_auto_build] Error 2 make[1]: Leaving directory `/build/buildd/boinc-7.2.0~nightly1~~git20130620+r19549' make: *** [build] Error 2 dpkg-buildpackage: error: debian/rules build gave error exit status 2 Gianfranco ----- Messaggio originale ----- > Da: David Anderson <[email protected]> > A: Gianfranco Costamagna <[email protected]> > Cc: Rom Walton <[email protected]>; "[email protected]" > <[email protected]> > Inviato: Domenica 7 Luglio 2013 22:39 > Oggetto: Re: boinc libstdc++ linking > > I believe we statically link the C++ library > because otherwise the executable won't run on systems with old .so > libraries. > What link problem are you seeing? > -- David > > On 06-Jul-2013 4:37 AM, Gianfranco Costamagna wrote: >> Hi David, Rom and all.
