Subject: [Caml-list] pic version of libasmrun not used
Date: Wed, 31 May 2017 10:12:18 +0200 [thread overview]
Message-ID: <20170531081218.GH26792@aepfle.de> (raw)

openSUSE Tumbleweed switched to gcc7, with the result that most ocaml
related packages fail to build. The reason is that libasmrun.a instead
of libasmrun_pic.a is used during linking:
[ 44s] + ocamlfind ocamlopt unix.cmxa -I /usr/lib64/ocaml/ocamlbuild /usr/lib64/ocaml/ocamlbuild/ocamlbuildlib.cmxa -linkpkg myocamlbuild.ml /usr/lib64/ocaml/ocamlbuild/ocamlbuild.cmx -o myocamlbuild
...
[ 44s] /usr/lib64/gcc/x86_64-suse-linux/7/../../../../x86_64-suse-linux/bin/ld: /usr/lib64/ocaml/libasmrun.a(startup_aux.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC
...
[ 44s] E: Failure("Command ''/usr/bin/ocamlbuild' src/oasis/oasis.cma src/oasis/oasis.cmxa src/oasis/oasis.a src/oasis/oasis.cmxs src/base/base.cma src/base/base.cmxa src/base/base.a src/base/base.cmxs src/builtin-plugins.cma src/builtin-plugins.cmxa src/builtin-plugins.a src/builtin-plugins.cmxs src/dynrun/dynrun.cma src/dynrun/dynrun.cmxa src/dynrun/dynrun.a src/dynrun/dynrun.cmxs src/ext/plugin-loader/src/plugin-loader.cma src/ext/plugin-loader/src/plugin-loader.cmxa src/ext/plugin-loader/src/plugin-loader.a src/ext/plugin-loader/src/plugin-loader.cmxs src/cli/cli.cma src/cli/Main.byte src/ext/userconf/src/userconf.cma src/ext/userconf/src/userconf.cmxa src/ext/userconf/src/userconf.a src/ext/userconf/src/userconf.cmxs -use-ocamlfind -tag debug' terminated with error code 10")
The workaround is to overwrite libasmrun.a in ocaml like this:
cp -av --remove-destination \
%{buildroot}%{_libdir}/ocaml/libasmrun_pic.a \
%{buildroot}%{_libdir}/ocaml/libasmrun.a
Is there a secret knob to let ocamlbuild select the pic version of libasmrun?
