[SOLVED] Problem with auto(re)conf under Windows 7 x64

When I used Windows XP Pro (32-bits), I never had a problem with compiling (ff)dcaenc thru MSYS+MinGW-w64,
but now that I've finally switched to Windows 7 (64-bits), this is what I get:

Code:
$ autoreconf -f -i -v
0 [main] perl 1616 fork_copy: linked dll data/bss pass 0 failed, 0x343000..0x343434, done 0, windows pid 1068, Win32 error 487
5044092 [main] perl 1616 fork_copy: linked dll data/bss pass 0 failed, 0x343000..0x343434, done 0, windows pid 672, Win32 error 487
12296473 [main] perl 1616 fork_copy: linked dll data/bss pass 0 failed, 0x343000..0x343434, done 0, windows pid 2204, Win32 error 487
autoreconf: Entering directory `.'
autoreconf: configure.ac: not using Gettext
autoreconf: running: aclocal --force -I m4
0 [main] perl 2816 fork_copy: linked dll data/bss pass 0 failed, 0x3C3000..0x3C3434, done 0, windows pid 2684, Win32 error 87
5275799 [main] perl 2816 fork_copy: linked dll data/bss pass 0 failed, 0x3C3000..0x3C3434, done 0, windows pid 2056, Win32 error 487
10311775 [main] perl 2816 fork_copy: linked dll data/bss pass 0 failed, 0x3C3000..0x3C3434, done 0, windows pid 2392, Win32 error 487

autoreconf: aclocal terminated by signal: 2

Looks like fork() is failing in your Cygwin/Mingw environment.

Emulating fork() on the Windows platform is a pretty complex and error-prone endeavor. It requires that all DLL's get loaded to the same memory-location in the new process as in the original process, which Windows doesn't guarantee.

Running the 'autorebase' script (rebaseall) might help in certain circumstances:

Thanks for chiming in, LoRd_MuldeR

The 'rebaseall' trick does not work for everyone, and did not work for me either :–/ For the time being at least, I've managed to setup an MSYS2 environment upon the MinGW toolchain from Nevcairiel's site plus fresh builds of the autotools suite. So far, so good
