Sorry, "in front of" was a misleading expression. I meant placed *after* exeinvoke.o (reading from right to left the link command). So on Ubuntu 16.04 x64 this fails (taken from the original build, the order is like in your link command): /usr/lib/gcc/x86_64-linux-gnu/5/collect2 -plugin /usr/lib/gcc/x86_64-linux-gnu/5/liblto_plugin.so -plugin-opt=/usr/lib/gcc/x86_64-linux-gnu/5/lto-wrapper -plugin-opt=-fresolution=/tmp/cccQFwXy.res -plugin-opt=-pass-through=-lgcc -plugin-opt=-pass-through=-lgcc_s -plugin-opt=-pass-through=-lc -plugin-opt=-pass-through=-lgcc -plugin-opt=-pass-through=-lgcc_s --sysroot=/ --build-id --eh-frame-hdr -m elf_x86_64 --hash-style=gnu --as-needed -dynamic-linker /lib64/ld-linux-x86-64.so.2 -z relro -o /home/gromero/hg/jdk9/hs-comp/build/linux-x86_64-normal-server-release/support/test/hotspot/jtreg/native/bin/invoke /usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu/crt1.o /usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu/crti.o /usr/lib/gcc/x86_64-linux-gnu/5/crtbegin.o -L/home/gromero/hg/jdk9/hs-comp/build/linux-x86_64-normal-server-release/support/modules_libs/java.base/amd64 -L/home/gromero/hg/jdk9/hs-comp/build/linux-x86_64-normal-server-release/support/modules_libs/java.base/amd64/server -L/usr/lib/gcc/x86_64-linux-gnu/5 -L/usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu -L/usr/lib/gcc/x86_64-linux-gnu/5/../../../../lib -L/lib/x86_64-linux-gnu -L/lib/../lib -L/usr/lib/x86_64-linux-gnu -L/usr/lib/../lib -L/usr/lib/gcc/x86_64-linux-gnu/5/../../.. --hash-style=both -z defs -O1 --allow-shlib-undefined -ljvm -lpthread /home/gromero/hg/jdk9/hs-comp/build/linux-x86_64-normal-server-release/support/test/hotspot/jtreg/native/support/exeinvoke/exeinvoke.o -lgcc --as-needed -lgcc_s --no-as-needed -lc -lgcc --as-needed -lgcc_s --no-as-needed /usr/lib/gcc/x86_64-linux-gnu/5/crtend.o /usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu/crtn.o but this succeeds (where -ljvm is after exeinvoke.o): /usr/lib/gcc/x86_64-linux-gnu/5/collect2 -plugin /usr/lib/gcc/x86_64-linux-gnu/5/liblto_plugin.so -plugin-opt=/usr/lib/gcc/x86_64-linux-gnu/5/lto-wrapper -plugin-opt=-fresolution=/tmp/ccIRdp31.res -plugin-opt=-pass-through=-lgcc -plugin-opt=-pass-through=-lgcc_s -plugin-opt=-pass-through=-lpthread -plugin-opt=-pass-through=-lc -plugin-opt=-pass-through=-lgcc -plugin-opt=-pass-through=-lgcc_s --sysroot=/ --build-id --eh-frame-hdr -m elf_x86_64 --hash-style=gnu --as-needed -dynamic-linker /lib64/ld-linux-x86-64.so.2 -z relro -o /home/gromero/hg/jdk9/hs-comp/build/linux-x86_64-normal-server-release/support/test/hotspot/jtreg/native/bin/invoke /usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu/crt1.o /usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu/crti.o /usr/lib/gcc/x86_64-linux-gnu/5/crtbegin.o -L/home/gromero/hg/jdk9/hs-comp/build/linux-x86_64-normal-server-release/support/modules_libs/java.base/amd64 -L/home/gromero/hg/jdk9/hs-comp/build/linux-x86_64-normal-server-release/support/modules_libs/java.base/amd64/server -L/usr/lib/gcc/x86_64-linux-gnu/5 -L/usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu -L/usr/lib/gcc/x86_64-linux-gnu/5/../../../../lib -L/lib/x86_64-linux-gnu -L/lib/../lib -L/usr/lib/x86_64-linux-gnu -L/usr/lib/../lib -L/usr/lib/gcc/x86_64-linux-gnu/5/../../.. --hash-style=both -z defs -O1 /home/gromero/hg/jdk9/hs-comp/build/linux-x86_64-normal-server-release/support/test/hotspot/jtreg/native/support/exeinvoke/exeinvoke.o -ljvm -lgcc --as-needed -lgcc_s --no-as-needed -lpthread -lc -lgcc --as-needed -lgcc_s --no-as-needed /usr/lib/gcc/x86_64-linux-gnu/5/crtend.o /usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu/crtn.o Full log: https://paste.fedoraproject.org/409607/raw/ Regards, Gustavo
