Bug #30591 is closed by the reason from http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30591#c6 . I would like to clone issue as cross build obj ecjx don't work in my case: The part of .../gcc/Makefile is: build=i486-pc-linux-gnu host=i486-pc-linux-gnu target=i486-pc-mingw32 The part of ../i486-mingw32/libjava/Makefile build_triplet = i486-pc-linux-gnu host_triplet = i486-pc-mingw32 target_triplet = i486-pc-mingw32 It seems to me ecjx can't be build as part of libjava build process: - build of ecjx.o ..../build/gcc-i486-mingw32/./gcc/xgcc .... -c -o ecjx.o ../../../src/gcc-4.4.0/libjava/ecjx.cc ... - build of executable : i486-pc-linux-gcj -o ecjx.exe .... ecjx.o make: i486-pc-linux-gcj: Command not found So far so good but may native compiler is : /usr/bin/gcj with symlink to /usr/bin/i486-slackware-linux-gcj So the first problem is why is not peeked correct compiler ? Note that C, C++, Fortran builds just fine. Next lets create a symlink to "missing" gcj compiler: # cd /usr/bin; ln -s gcj i486-pc-linux-gc $ make ecjx.exe i486-pc-linux-gcj -o ecjx.exe ... ecjx.o ecjx.o: file not recognized: File format not recognized collect2: ld returned 1 exit status And this is expected as : $ file ecjx.o ecjx.o: 80386 COFF executable not stripped - version 30821 -- Summary: Cross build fails because native gcj needed to build ecjx Product: gcc Version: 4.4.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: java AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: bugtrack at roumenpetrov dot info GCC build triplet: i486-pc-linux-gnu GCC host triplet: i486-pc-linux-gnu GCC target triplet: i486-pc-mingw32 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42311
