Re: armflang: error: unknown argument: '-soname'
While libtool has a new maintainer (Alex Ameen), essentially nothing happens, which is quite unfortunate... 1) libtool 2.4.7 was released in March 2022 (I don't know if Alex did it), which isn't so terribly long ago. Sure, maintainers should at least confirm bug reports and patches, even if releases don't happen quickly (pace my own efforts with automake), but ... 2) When a package appears to be unmaintained, the first thing to do is simply write the maintainer to see what the story is. If there is no response, the next step is to write maintain...@gnu.org. It's their responsibility to make continued efforts to contact the maintainer, up to and including sending paper mail. And look for a new maintainer if need be. 3) If that also fails, the final fallback is to write gnu-advis...@gnu.org and/or r...@gnu.org. Best, Karl

Re: armflang: error: unknown argument: '-soname'
I confirm that the patch still works against today's git version: $ libtool --version libtool (GNU libtool) 2.4.7.4-1ec8f I just added "flang*" in addition to "armflang*": https://savannah.gnu.org/support/index.php?110947 I'm also asking in libt...@gnu.org why 2.4.6 is still the latest stable relase, if the dev branch is already at 2.4.7.4.

Re: armflang: error: unknown argument: '-soname'
Dear Anton, here is a patch for libtool that Francois Coppens and I submitted to libtool in February. I think we did something went wrong in the PR process because it has still not been included... Maybe you can submit it again to the libtool team, it is not a big change and it is quite important for us too to have this patch included. best, Anthony $ git diff 1ec8fa28dcb29500d485c136db28315671ec4c3b diff --git a/m4/libtool.m4 b/m4/libtool.m4 index 79a2451e..df1a7860 100644 --- a/m4/libtool.m4 +++ b/m4/libtool.m4 @@ -4719,6 +4719,12 @@ m4_if([$1], [CXX], [ _LT_TAGVAR(lt_prog_compiler_pic, $1)='-fPIC' _LT_TAGVAR(lt_prog_compiler_static, $1)='-static' ;; + # ARM flang + armflang*) +_LT_TAGVAR(lt_prog_compiler_wl, $1)='-Wl,' +_LT_TAGVAR(lt_prog_compiler_pic, $1)='-fPIC' +_LT_TAGVAR(lt_prog_compiler_static, $1)='-static' +;; # Lahey Fortran 8.1. lf95*) _LT_TAGVAR(lt_prog_compiler_wl, $1)='-Wl,' On Fri, 2023-10-20 at 10:47 +, Shterenlikht, Anton wrote: > This seems like an automake issue, not libtool. > > The libtool produced by running configure has: > > 11661 # ### BEGIN LIBTOOL TAG CONFIG: FC > 11662 > 11663 # The linker used to build libraries. > 11664 LD="/arm-compiler-for-linux_23.10_AmazonLinux-2/gcc- > 12.2.0_AmazonLinux-2/aarch64-linux-gnu/bin/ld" > 11665 > 11666 # How to create reloadable object files. > 11667 reload_flag=" -r" > 11668 reload_cmds="\$LD\$reload_flag -o \$output\$reload_objs" > 11669 > 11670 # Commands used to build an old-style archive. > 11671 old_archive_cmds="\$AR \$AR_FLAGS \$oldlib\$oldobjs~\$RANLIB > \$tool_oldlib" > 11672 > 11673 # A language specific compiler. > 11674 CC="armflang" > 11675 > 11676 # Is the compiler the GNU compiler? > 11677 with_gcc=no > 11678 > 11679 # Compiler flag to turn off builtin functions. > 11680 no_builtin_flag="" > 11681 > 11682 # Additional compiler flags for building library objects. > 11683 pic_flag="" > 11684 > 11685 # How to pass a linker flag through the compiler. > 11686 wl="" > > Note that wl= is emtpy. > > Compare with the portion of this file for C compiler: > > 317 # A language specific compiler. > 318 CC="mpicc" > 319 > 320 # Is the compiler the GNU compiler? > 321 with_gcc=yes > 322 > 323 # Compiler flag to turn off builtin functions. > 324 no_builtin_flag=" -fno-builtin -fno-rtti -fno-exceptions" > 325 > 326 # Additional compiler flags for building library objects. > 327 pic_flag=" -fPIC -DPIC" > 328 > 329 # How to pass a linker flag through the compiler. > 330 wl="-Wl," > > > This simple patch works: > > sed -i 's|wl=""|wl="-Wl,"|' libtool > > and gives: > > libtool: link: armflang -shared -g -fopenmp > -mcpu=neoverse-512tvb -march=armv8.4-a+sve -fopenmp -Wl,-soname > -Wl,libp2.so.0 -o .libs/libp2.so.0.0.0 > > However, this crude hack will not work with "make distcheck", > because it will generate a new libtool. > > Still, I'm trying to understand if this is a bug in autotools, > and if there is a workaround via edits in configure.ac and/or > Makefile.am. > > Thank you > > Anton > > > On 20 Oct 2023, at 08:40, Shterenlikht, Anton < > > shterenli...@par-tec.com> wrote: > > > > [also posted in libt...@gnu.org] > > > > Please help me understand how to deal correctly with this error: > > > > libtool: link: armflang -shared-g -soname > > libp2.so.0 -o .libs/libp2.so.0.0.0 > > armflang: error: unknown argument: '-soname' > > > > > > I see this issue mentioned in multiple places, e.g: > > > > https://github.com/HDFGroup/hdf5/issues/366 > > > > with the solution that "-Wl," must be prepended somehow to "- > > soname". > > > > But I'm not sure what changes I need to do > > to my configure.ac and/or Makefile.am > > to fix this correctly. > > > > For comparison, here's how the same line looks like when > > I use gfortran: > > > > libtool: link: gfortran -shared -fPIC -g > > -O2 -Wl,-soname -Wl,libp2.so.0 -o .libs/libp2.so.0.0.0 > > > > > > Thank you > > > > Anton > >

Re: armflang: error: unknown argument: '-soname'
Hi Anton - thanks for the report. https://github.com/HDFGroup/hdf5/issues/366 with the solution that "-Wl," must be prepended somehow to "-soname". Why do you think this is not a libtool issue? Isn't it libtool's job to figure out the arguments that need to be passed? The fact that the -Wl is provided for gfortran and not for armflang makes me think even more that it is libtool. At first glance, the string "soname" does not appear in the Automake sources. But I'm not sure what changes I need to do to my configure.ac and/or Makefile.am to fix this correctly. I wish I had a workaround for you, but I just don't know the answer. Someone else here probably knows better, else I suggest posting to bug-libt...@gnu.org, ideally with a reproducible case. Happy linking, Karl
armflang: error: unknown argument: '-soname'
[also posted in libt...@gnu.org] Please help me understand how to deal correctly with this error: libtool: link: armflang -shared-g -soname libp2.so.0 -o .libs/libp2.so.0.0.0 armflang: error: unknown argument: '-soname' I see this issue mentioned in multiple places, e.g: https://github.com/HDFGroup/hdf5/issues/366 with the solution that "-Wl," must be prepended somehow to "-soname". But I'm not sure what changes I need to do to my configure.ac and/or Makefile.am to fix this correctly. For comparison, here's how the same line looks like when I use gfortran: libtool: link: gfortran -shared -fPIC -g -O2 -Wl,-soname -Wl,libp2.so.0 -o .libs/libp2.so.0.0.0 Thank you Anton smime.p7s Description: S/MIME cryptographic signature
Re: armflang: error: unknown argument: '-soname'
This seems like an automake issue, not libtool. The libtool produced by running configure has: 11661 # ### BEGIN LIBTOOL TAG CONFIG: FC 11662 11663 # The linker used to build libraries. 11664 LD="/arm-compiler-for-linux_23.10_AmazonLinux-2/gcc-12.2.0_AmazonLinux-2/aarch64-linux-gnu/bin/ld" 11665 11666 # How to create reloadable object files. 11667 reload_flag=" -r" 11668 reload_cmds="\$LD\$reload_flag -o \$output\$reload_objs" 11669 11670 # Commands used to build an old-style archive. 11671 old_archive_cmds="\$AR \$AR_FLAGS \$oldlib\$oldobjs~\$RANLIB \$tool_oldlib" 11672 11673 # A language specific compiler. 11674 CC="armflang" 11675 11676 # Is the compiler the GNU compiler? 11677 with_gcc=no 11678 11679 # Compiler flag to turn off builtin functions. 11680 no_builtin_flag="" 11681 11682 # Additional compiler flags for building library objects. 11683 pic_flag="" 11684 11685 # How to pass a linker flag through the compiler. 11686 wl="" Note that wl= is emtpy.

Still, I'm trying to understand if this is a bug in autotools, and if there is a workaround via edits in configure.ac and/or Makefile.am.
