Sorry for missing your earlier response. To set 'wl' for
flang, armflang, flang-new, and ftn, the following patch
should work:
--- a/m4/libtool.m4
+++ b/m4/libtool.m4
@@@ -4805,7 -4805,7 +4805,7 @@@ m4_if([$1], [CXX],
_LT_TAGVAR(lt_prog_compiler_pic, $1)='-KPIC'
_LT_TAGVAR(lt_prog_compiler_static, $1)='-static'
;;
-- *flang)
++ *flang* | ftn*)
# Flang compiler.
_LT_TAGVAR(lt_prog_compiler_wl, $1)='-Wl,'
_LT_TAGVAR(lt_prog_compiler_pic, $1)='-fPIC'
Could you test this again in your environment?
The libtool script generated for my project has: # A language specific compiler. CC="ftn" # Is the compiler the GNU compiler? with_gcc=no # Compiler flag to turn off builtin functions. no_builtin_flag="" # Additional compiler flags for building library objects. pic_flag="" # How to pass a linker flag through the compiler. wl="" I can fix this with sed -i -e 's/wl=""/wl="-Wl,"/g' libtool as I reported in https://savannah.gnu.org/patch/?9442 However, what is the right way to deal with this? Finally, will the patch from https://savannah.gnu.org/patch/?9442 be included in the upcoming libtool release?
The previous patch was applied in the latest alpha release of libtool 2.5.0, and you should see it in the upcoming beta and stable releases.
Thank you Anton
