--- Comment #2 from H.J. Lu <hjl.tools at gmail dot com> 2013-02-15 23:59:30 UTC --- The command line is /export/gnu/import/git/gcc-test-intel64/bld/gcc/xgcc -B/export/gnu/import/git/gcc-test-intel64/bld/gcc/ /export/gnu/import/git/gcc-test-intel64/src-trunk/libjava/testsuite/libjava.jni/invocation/PR16923.c -I. -I.. -I/export/gnu/import/git/gcc-test-intel64/src-trunk/libjava/testsuite/libjava.jni -I/export/gnu/import/git/gcc-test-intel64/src-trunk/libjava/testsuite/../include -I/export/gnu/import/git/gcc-test-intel64/src-trunk/libjava/testsuite/../classpath/include -fdollars-in-identifiers -L/export/gnu/import/git/gcc-test-intel64/bld/x86_64-unknown-linux-gnu/32/libjava/.libs -ljvm -lm -m32 -o PR16923 ld finds libgcj.so via -ljvm. It should reject it: /usr/local/bin/ld: /export/gnu/import/git/gcc-test-intel64/bld/gcc/crtbegin.o: undefined reference to symbol '_Jv_RegisterClasses' /usr/local/bin/ld: note: '_Jv_RegisterClasses' is defined in DSO /export/gnu/import/git/gcc-test-intel64/bld/x86_64-unknown-linux-gnu/libjava/.libs/libgcj.so.14 so try adding it to the linker command line /export/gnu/import/git/gcc-test-intel64/bld/x86_64-unknown-linux-gnu/libjava/.libs/libgcj.so.14: could not read symbols: Invalid operation
