I am trying to compile on CygWin 64 bits the (presumed) 32 bits wake on lan tool here created by Thomas Krennwallner, supposed to compile on Unix and Windows under CygWin.
After download I did:
tar -zxvf wol-0.7.1.tar.gz
and, in order to update its configure.guess script (the included one is a bit old: from 2004), I have downloaded it from here.
So, according to its README file, I do:
./configure
and I get:
Luis@Windu /cygdrive/h/Temporal/wol/wol-0.7.1
$ ./configure
checking build system type... x86_64-unknown-cygwin
checking host system type... x86_64-unknown-cygwin
checking for a BSD-compatible install... /usr/bin/install -c

checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking for style of include used by make... GNU
checking for gcc... gcc
checking for C compiler default output file name... configure: error: C compiler cannot create executables
See `config.log' for more details.
This is my config.log:
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.
It was created by configure, which was
generated by GNU Autoconf 2.59. Invocation command line was

That seems to be reporting the expected problem when compiling a 32 bits program on a 64 bits platform.
Is it possible to solve this?
I have read some info about using the flag "-m32" on the gcc compiler, or sending some variables (exporting) before the compiling, but the problem seems to come rather from the configuring part, not the compiling. The order seems to be:
- .configure
- make
- make check
- make install
- make clean
and the first step fails :-( .
Anyway, I tried:
export CFLAGS='-m32' export CXXFLAGS='-m32' export LDFLAGS='-m32'
But the ./configure script keeps failing.
And, by the way, I tried to ignore the error and continue (2nd step) compiling:
make
but it yields some error message reporting (sorry, my CygWin seems to be in spanish) something like No objective specified and no makefile found.
I think that solving this problem could help me to learn a way to compile 32 bits programs on CygWin 64.
I request some help, please.
P.S: I know this tool has a Win32 version available to download, as well as there are another programs for wake on LAN. But where is the learning on that way to solve things?
EDIT: I have installed the following package names on CygWin:
gcc-core
gdb
make
mingw-gcc-core
mingw-gcc-g++
mingw-w32api
EDIT-2: I have saved my day by uninstalling CygWin 64 bits and installing 32 bits version. This everything went smooth and fine.
Answer
Cygwin packages come in two versions, a 64-bit version and a 32-bit version. As the 64-bit library is newer than the 32-bit library, there are some missing libraries and programs.
You can have BOTH the 32-bit and the 64-bit Cygwin installed concurrently without any problems. Thus if you wanted to compile and go on using 32-bit mode, install the 32-bit cygwin and invoke its bash shell.
Cygwin 32-bit is usually installed in c:\cygwin and the 64-bit cygwin is installed in c:\cygwin64.
So in summary, if you need 32-bit capabilities install the 32-bit cygwin and all the necessary packages you need to complete your task.
NOTE: 32-bit programs WILL run on 64-bit windows platforms.
