--000000000000df10a505c5bd3637 Content-Type: text/plain; charset="UTF-8" Hi, lang/ocaml port is marked as broken on aarch64 and I would like to contribute and have it fixed. The broken reason is incorrect as of now: BROKEN_aarch64= Does not build: sh: as: not found If I comment this line out, "as" is correctly found given the port dependency from binutils: BUILD_DEPENDS= as:devel/binutils The build process stops with: ld: error: can't create dynamic relocation R_AARCH64_LDST64_ABS_LO12_NC against symbol: camlUnix in readonly segment; recompile object files with -fPIC or pass '-Wl,-z,notext' to allow text relocations in the output >>> defined in unix.a(unix.o) >>> referenced by unix.ml:863 >>> unix.o:(camlUnix__waitpid_non_intr_1853) in archive unix.a ld: error: too many errors emitted, stopping now (use -error-limit=0 to see all errors) cc: error: linker command failed with exit code 1 (use -v to see invocation) File "caml_startup", line 1: Error: Error during linking gmake[4]: *** [../Makefile:74: unix.cmxs] Error 2 gmake[4]: Leaving directory '/wrkdirs/usr/ports/lang/ocaml/work/ocaml-4.05.0/otherlibs/unix' gmake[3]: *** [Makefile:1055: otherlibrariesopt] Error 2 gmake[3]: Leaving directory '/wrkdirs/usr/ports/lang/ocaml/work/ocaml-4.05.0' gmake[2]: *** [Makefile:465: opt.opt] Error 2 gmake[2]: Leaving directory '/wrkdirs/usr/ports/lang/ocaml/work/ocaml-4.05.0' gmake[1]: *** [Makefile:531: world.opt] Error 2 gmake[1]: Leaving directory '/wrkdirs/usr/ports/lang/ocaml/work/ocaml-4.05.0' *** Error code 1 Stop. make: stopped in /usr/ports/lang/ocaml Trying to fix this issue by adding -fPIC to CONFIGURE_ARGS does nothing, in the sense that the option actually adds -fPIC to ld args, but the error remains. So I went the other way and changed LDFLAGS as suggested by the error message: LDFLAGS_aarch64= -Wl,-z,notext In this case I hit an obscure error when making with make -j <numcpus>: boot/ocamlrun ./ocamlopt -g -nostdlib -I stdlib -I otherlibs/dynlink -strict-sequence -principal -absname -w +a-4-9-41-42-44-45-48 -warn-error A -bin-annot -safe-string -strict-formats -I utils -I parsing -I typing -I bytecomp -I middle_end -I middle_end/base_types -I asmcomp -I driver -I toplevel -c middle_end/simplify_boxed_integer_ops.ml File "/usr/ports/lang/ocaml/work/ocaml-4.05.0/_none_", line 1: Warning 58: no cmx file was found in path for module Compilenv, and its interface was not compiled with -opaque boot/ocamlrun ./ocamlopt -g -nostdlib -I stdlib -I otherlibs/dynlink -strict-sequence -principal -absname -w +a-4-9-41-42-44-45-48 -warn-error A -bin-annot -safe-string -strict-formats -I utils -I parsing -I typing -I bytecomp -I middle_end -I middle_end/base_types -I asmcomp -I driver -I toplevel -c middle_end/simplify_primitives.ml File "/usr/ports/lang/ocaml/work/ocaml-4.05.0/asmcomp/selection.ml", line 1: Error: Some fatal warnings were triggered (1 occurrences) gmake[4]: *** [Makefile:1270: asmcomp/selection.cmx] Error 2 gmake[4]: *** Waiting for unfinished jobs.... gmake[4]: Leaving directory '/usr/ports/lang/ocaml/work/ocaml-4.05.0' gmake[3]: *** [Makefile:464: opt.opt] Error 2 gmake[3]: Leaving directory '/usr/ports/lang/ocaml/work/ocaml-4.05.0' gmake[2]: *** [Makefile:531: world.opt] Error 2 gmake[2]: Leaving directory '/usr/ports/lang/ocaml/work/ocaml-4.05.0' *** [do-build] Error code 1 make[1]: stopped in /usr/ports/lang/ocaml 1 error make[1]: stopped in /usr/ports/lang/ocaml *** [stage] Error code 2 make: stopped in /usr/ports/lang/ocaml 1 error make: stopped in /usr/ports/lang/ocaml If I continue without -j, ld fails with a similar error: ld: error: relocation R_AARCH64_LDST64_ABS_LO12_NC cannot be used against symbol camlUnix; recompile with -fPIC Note: -fPIC is enabled. I am stuck, can someone suggest how to proceed? Thank you. BR, --000000000000df10a505c5bd3637--
