--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> --- Btw, it looks even wrong -- the host C++ compiler built some of the objects in the failing link (libcpp.a). So xg++ might end up linking the wrong standard library (try building with clang++ and libc++?) ../../xg++ -B../../ -B../../../x86_64-pc-linux-gnu/libstdc++-v3/src/.libs -B../../../x86_64-pc-linux-gnu/libstdc++-v3/libsupc++/.libs -L../../../x86_64-pc-linux-gnu/libstdc++-v3/src/.libs -L../../../x86_64-pc-linux-gnu/libstdc++-v3/libsupc++/.libs -static-libstdc++ -static-libgcc -I- -I../rts -I. -I/tmp/trunk2/gcc/ada -static-libstdc++ -static-libgcc -DIN_GCC -g -O2 -W -Wall -o ../../gnatmake b_gnatm.o a-except.o ali.o ali-util.o aspects.o s-casuti.o alloc.o atree.o binderr.o butil.o casing.o csets.o debug.o elists.o einfo.o errout.o erroutc.o errutil.o err_vars.o fmap.o fname.o fname-uf.o fname-sf.o gnatmake.o gnatvsn.o hostparm.o interfac.o i-c.o i-cstrin.o krunch.o lib.o make.o makeusg.o makeutl.o mlib.o mlib-fil.o mlib-prj.o mlib-tgt.o mlib-tgt-specific.o mlib-utl.o namet.o nlists.o opt.o osint.o osint-m.o output.o prj.o prj-attr.o prj-attr-pm.o prj-com.o prj-dect.o prj-env.o prj-conf.o prj-pp.o prj-err.o prj-ext.o prj-nmsc.o prj-pars.o prj-part.o prj-proc.o prj-strt.o prj-tree.o prj-util.o restrict.o rident.o s-exctab.o s-secsta.o s-stalib.o s-stoele.o scans.o scng.o sdefault.o sfn_scan.o s-purexc.o s-htable.o scil_ll.o sem_aux.o sinfo.o sinput.o sinput-c.o sinput-p.o snames.o stand.o stringt.o styleg.o stylesw.o system.o validsw.o switch.o switch-m.o table.o targparm.o tempdir.o tree_io.o types.o uintp.o uname.o urealp.o usage.o widechar.o ../link.o ../targext.o ../../ggc-none.o ../../libcommon-target.a ../../libcommon.a ../../../libcpp/libcpp.a ../rts/libgnat.a ../../../libbacktrace/.libs/libbacktrace.a ../../../libiberty/libiberty.a -ldl make[3]: ../../xg++: Command not found ../gcc-interface/Makefile:2647: recipe for target '../../gnatmake' failed make[3]: *** [../../gnatmake] Error 127
