Hi, I'm having trouble subscribing to [EMAIL PROTECTED] I've sent a half dozen subscribe emails, and haven't been added yet. (over several days) I've also sent emails to [EMAIL PROTECTED], and have received no response. Could someone please add me to this mailing list?
I've successfully cross compiled apr on cygwin to mingw. I've already had one patch go upstream to autoconf, which fixes a problem AC_CHECK_SIZEOF. I have two very small other problems, that need to be sent upstream, and then trunk should work out of the box. First, and oddly enough, the buildconf script fails for me because build/buildcheck.sh doesn't recognize my libtool --version. I don't know sed well enough, and thought someone here would quickly be able to spot the problem. If not, I'll have to look deeper. $ libtool --version 2>/dev/null ltmain.sh (GNU libtool) 1.5.23a (1.1220.2.412 2006/10/13 14:13:30) Copyright (C) 2006 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. This command is failing by giving me no output. $ libtool --version 2>/dev/null|sed -e 's/([^)]*)//g;s/^[^0-9]*//;s/[- ].*//g;q' So, I changed it to $ libtool --version 2>/dev/null|sed -e 's/([^)]*)//g;s/^[^0-9]*//;' and it worked, but I don't think that is the correct fix. Any ideas? Secondly, the APR_CHECK_SIZEOF_EXTENDED isn't working for me because the default for the cross compiled size is 8. However, ssize_t for me is 4. So, the configure fails. I made this change: -APR_CHECK_SIZEOF_EXTENDED([#include <sys/types.h>], ssize_t, 8) +AC_CHECK_SIZEOF([ssize_t], [#include <stdio.h> +#include <sys/types.h>]) and things work nicely. Would a patch like this be acceptable? There are 5 changes I made just like this. Finally, the macro APR_CHECK_SIZEOF_EXTENDED could probably be removed. So, after patching autoconf, and making these two patches to apr, I was able to cross compile on cygwin with this command, ./configure apr_cv_tcp_nodelay_with_cork=no ac_cv_func_setpgrp_void=yes ac_cv_file__dev_zero=no --build=i686-pc-cygwin --host=i686-pc-mingw32 CC='gcc -mno-cygwin' CXX='g++ -mno-cygwin' I was able to take a sample program, and run it on a machine that did not have cygwin installed, and it ran fine. It was simply a hello world type program with apr stuff in it. I would really appreciate if these thoughts could be considered, so I could create a patch to send upstream. Thanks, Bob Rossi
