Re: strnlen on Mingw [Was Re: Stable 20090129 compiled to windows]

[John Darrington]

Try editing configure to put some diagnostics in.  Find out which
branch it's taking and what the valud of $cross_compiling is.

     nothing either. I'm starting to think that its maybe a bug on
     configure because of this:
     on configure.log I get:
     
     configure:34377: result: no
     configure:34395: checking whether strnlen is declared
     configure:34424: i686-mingw32-gcc -std=gnu99 -c -g -O2
     -Wdeclaration-after-statement -fgnu89-inline  conftest.c >&5
     conftest.c: In function 'main':
     conftest.c:163: error: 'strnlen' undeclared (first use in this function)
     conftest.c:163: error: (Each undeclared identifier is reported only once
     conftest.c:163: error: for each function it appears in.)
     configure:34431: $? = 1
     
     and then this:
     
     configure:58374: checking for working strnlen
     configure:58449: result: yes
     
     and on the very bottom, this:
     
     ac_cv_func_strnlen_working=yes
     
     
     So configure can't find strnlen, and then tells that it works. If you
     look at configure script there is:
     
       { $as_echo "$as_me:$LINENO: checking for working strnlen" >&5
     $as_echo_n "checking for working strnlen... " >&6; }
     if test "${ac_cv_func_strnlen_working+set}" = set; then
       $as_echo_n "(cached) " >&6
     else
       if test "$cross_compiling" = yes; then
       ac_cv_func_strnlen_working=no
     else
     
     as far as I understand this, ac_cv_func_strnlen_working from the first
     if should be the return of the compile of the strnlen test, and
     because its 1 (configure:34431: $? = 1) the first if should return
     false, and how we are doing cross_compiling the
     ac_func_strnlen_working should be set to 'no', but it is set to yes.
     
     Am I interpreting it wrong?
