actual config log
oops, operator paste error...
looks like the problem is with your use of LTO flags rather than being aarch64 specific. from the log: configure:5332: checking for dlsym configure:5369: aarch64-unknown-linux-gnu-gcc -o conftest -march=armv8-a -mtune=cortex-a53 -O2 -flto -ftree-vectorize -ftree-loop-distribution -fvect-cost-model=cheap -O2 -flto -fuse-linker-plugin conftest.c >&5 configure:5372: $? = 0 configure:5375: test -s conftest configure:5378: $? = 0 configure:5388: result: yes configure:5470: checking whether able to link to dl*() functions configure:5491: aarch64-unknown-linux-gnu-gcc -o conftest -march=armv8-a -mtune=cortex-a53 -O2 -flto -ftree-vectorize -ftree-loop-distribution -fvect-cost-model=cheap -O2 -flto -fuse-linker-plugin conftest.c >&5 /var/tmp/portage/sys-libs/ncurses-6.0-r1/temp/ccaRaPzO.ltrans0.ltrans.o:<artificial>:function main: error: undefined reference to 'dlopen' /var/tmp/portage/sys-libs/ncurses-6.0-r1/temp/ccaRaPzO.ltrans0.ltrans.o:<artificial>:function main: error: undefined reference to 'dlsym' /var/tmp/portage/sys-libs/ncurses-6.0-r1/temp/ccaRaPzO.ltrans0.ltrans.o:<artificial>:function main: error: undefined reference to 'dlclose' collect2: error: ld returned 1 exit status configure:5494: $? = 1 so it first tried to see if you could use dlsym w/out -ldl, and that passed, but then it tried to use more libdl funcs w/out -ldl, and that failed. try scaling back your compiler settings to something basic and see if ncurses passes. It's not LTO, rather gold linker is less sloppy (or more strict) than bfd is. You can strip out the LTO flags to nothing and gold linker still fails the configure test. So either falling all the way back to no-gold and no-lto works, or adding the linker args with all the above flags enabled works; it has to be one or the other. I love it when configure has so many different errors to choose from...

config log using bfd linker
i can't reproduce this either with aarch64 or x86_64, gold or bfd. the libdl tests only run when building w/gpm support. you could always disable that since gpm only matters on a console. not related to arm64, but to lto. duping to a newer bug as it has more details. *** This bug has been marked as a duplicate of bug 606142 *** |
