Dear libtool-patches,
On Linux on 'aarch64' using the 'armflang' compiler I got the following
error:
FCLD src/libqmckl.la
clang-13: error: unknown argument: '-soname'
clang-13: error: no such file or directory: 'libqmckl.so.0'
make[2]: *** [Makefile:1203: src/libqmckl.la] Error 1
make[2]: Leaving directory '/users/m23005/scemama/qmckl'
make[1]: *** [Makefile:1520: all-recursive] Error 1
make[1]: Leaving directory '/users/m23005/scemama/qmckl'
make: *** [Makefile:1046: all] Error 2
John C. Linford <john.linf...@arm.com> from ARM suggested the following
workaround for end users:
$ ./configure ...
$ sed -i -e 's#wl=""#wl="-Wl,"#g' libtool
$ sed -i -e 's#pic_flag=""#pic_flag=" -fPIC -DPIC"#g' libtool
$ make
This works, so I patched the 'libtool.m4' file to include the correct
flags for the 'armflang' compiler:
$ git format-patch --stdout origin/master

This works as well and the end user does no longer have to use the
proposed workaround.
I remain at your disposal for more inforation if needed.
With kind regards,
