cross-compiling problems

[Schleicher Ralph (LLI)]

ltmain.sh (GNU libtool) 1.4.2 (1.922.2.53 2001/09/11 03:18:52)
automake (GNU automake) 1.6.1
autoconf (GNU Autoconf) 2.53

Hi,

I encountered a few problems with Libtool while cross-compiling from
hppa2.0-hp-hpux10.20 to i386-pc-mingw32msvc.


* Libtool does not recognize AC_LIBTOOL_WIN32_DLL.  After all, I was
able to cross-compile Windows DLLs with the following workaround in
configure.ac:

dnl Process this file with autoconf to produce a configure script.

AC_INIT([hello], [1.0])
AM_INIT_AUTOMAKE([foreign no-define no-dependencies])
AC_CONFIG_SRCDIR([hello.c])
AC_CONFIG_FILES([Makefile])

AC_PROG_CC
AC_PROG_LN_S
AC_PROG_INSTALL
AC_PROG_MAKE_SET
AC_LIBTOOL_WIN32_DLL
# Work around an Autoconf/Libtool bug.
ifdef([AC_PROVIDE_AC_LIBTOOL_WIN32_DLL],,
define([AC_PROVIDE_AC_LIBTOOL_WIN32_DLL]))
AM_PROG_LIBTOOL

AC_OUTPUT


* Libtool compiles impgen for the host machines, which can't be run
on the build machine.  Here is an example (`\\' are line continuation
marks):

/bin/sh ../../libtool --mode=link i386-pc-mingw32msvc-gcc -O2 \\
-L/home/raid/cea_adm/i386-pc-mingw32msvc/lib -o libdf.la -rpath \\

      ends here \*\// { s/^# //;s/^# *$//; p; }" -e d < ../../libtool > \\
      .libs/impgen.c
      test -f .libs/impgen.exe || (cd .libs && \\
      if test "x" != "x" ; then  -o impgen impgen.c ; \\
      else i386-pc-mingw32msvc-gcc -o impgen impgen.c ; fi) 
      .libs/impgen \\
      /home/raid/cea_adm/i386-pc-mingw32msvc/lib/libjpeg-62.dll > \\
      .libs/libjpeg-62.dll-def
../../libtool: .libs/impgen: Execute permission denied.
make[4]: *** [libdf.la] Error 126

Looks as if the line

      if test "x" != "x" ; then  -o impgen impgen.c ; \\
      else i386-pc-mingw32msvc-gcc -o impgen impgen.c ; fi)

causes the error.
