Thanks for your bug report. The issue you report was already fixed in autoconf 2.69:
- AC_PROG_LN_S and AS_LN_S now fall back on 'cp -pR' (not 'cp -p') if 'ln -s' does not work. This works better for symlinks to directories. http://git.savannah.gnu.org/gitweb/?p=autoconf.git;a=commitdiff;h=17ea0df46f819a9b64c21151983a5c5b8561fefb cu Adrian On Sat, Sep 22, 2012 at 05:58:45PM +0200, daniel.f.sta...@freenet.de wrote: > Dear Sir or Madam, > > running autoconf (GNU Autoconf) 2.68 obtained from > http://sourceforge.net/projects/mingw/files/MinGW/Extension/autoconf/autoconf2.5/autoconf2.5-2.68-1/ > with the following configure.ac: > > AC_PREREQ(2.64) > AC_INIT > AC_PROG_LN_S > > leads to a wrongly created configure file that contains: > > if (echo >conf$$.file) 2>/dev/null; then > if ln -s conf$$.file conf$$ 2>/dev/null; then > as_ln_s='ln -s' > # ... but there are two gotchas: > # 1) On MSYS, both `ln -s file dir' and `ln file dir' fail. > # 2) DJGPP < 2.04 has no symlinks; `ln -s' . > # In both cases, we have to default to `cp -p'. > ln -s conf$$.file conf$$.dir 2>/dev/null && test ! -f conf$$.exe || > as_ln_s='cp -p' > elif ln conf$$.file conf$$ 2>/dev/null; then > as_ln_s=ln > else > as_ln_s='cp -p' > fi > else > as_ln_s='cp -p' > fi > > This is wrong as cp -p does not replace ln or ln -s on MSYS for directories. > A better replacement could be cp -pr. > Please consider this change in the upcoming releases. > > Best regards, > Daniel Starke
