This fails with lld, where the mingw/coff part of lld doesn't support linker script. It does support response files (which also GNU ld does) though, so by making libtool check for support for response files before linker script (which is assumed to be supported if with_gnu_ld is set), this issue can be avoided. The attached patch accomplishes this. Are there any drawbacks to this approach, other than being less tested than the current status quo? This patch has been carried in msys2's copy of libtool since late last year, with no reported issues to my knowledge. // Martin --8323329-1720310909-1565816304=:2829 Content-Type: text/x-diff;
