Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
When testing libtool-2.5.0, I got one test failure in test 170
(bug_62343.at for -no-canonical-prefixes):

170. bug_62343.at:26: 170. Use -no-canonical-prefixes flag (bug_62343.at:26): FAILED (bug_62343.at:38)
Any idea how to further probe what's going on? I'm not sure why it's
even trying to use a linker plugin.
If I run manually, I do get the same error at least:
$ g++ -o libx.la -no-canonical-prefixes x.lo
g++: fatal error: ‘-fuse-linker-plugin’, but liblto_plugin.so not found
compilation terminated.
I'm also confused as I *do* have the plugin at
/usr/libexec/gcc/x86_64-pc-linux-gnu/15/liblto_plugin.so and it works
normally in other cases.
If I drop -no-canonical-prefixes, it works fine. (Caveat: I've not
looked up what the flag actually does.)
thanks,
sam
