Cygwin
Cygwin is a UNIX environment for Windows. It's located at http://sources.redhat.com/cygwin/
When running the setup program, in the 'Select Packages' dialog box, choose to install gcc2, gcc-mingw, make and mingw-runtime under the 'Category' field.
Install JDK 1.3.1
Install JDK 1.3.1 under cygwin's '/usr/local'. For example, if cygwin is install at 'd:/cygwin', install JDK at 'd:/cygwin/usr/local/jdk1.3.1'. This will make cygwin find jdk more easily.
Edit cygwin's '/etc/profile'. Add the following
line:
PATH="/usr/local/jdk1.3.1/bin:$PATH"
chmod a+x /usr/local/jdk1.3.1/bin/*
Note: Doing this is for make to be able to determine
they are executables.
J2ME MIDP 2.0
MIDP is built on top of CLDC. Therefore, you need to download J2ME CLDC 1.0.4 first from Sun's website at http://java.sun.com/j2me/download.html
In cygwin, unzip j2me_cldc-1_0_4-fcs-src-b30-winunix-13_nov_2002.zip
mv j2me_cldc cldc1.0.4fcs
Download J2ME MIDP 2.0, Windows version
In cygwin, unzip midp-2_0-fcs-src-b45-windows-i686-12_nov_2002.zip
chmod -R u+w midp2.0fcs
Modify build/win32/kvm/makefiles/Defs-pre.gmk,
change 'gcc' to 'gcc-2'.
Note: This is because Cygwin's gcc (gcc 3.2) can't
handle -mno-cygwin correctly. Therefore, we need
to use gcc-2 (gcc 2.95.3) instead.
Modify build/win32/kvm/Platform.gmk:
KVM_DIR = $(BUILD_DIR)/../../../cldc1.0.4fcs
Build J2ME MIDP 2.0
cd midp2.0fcs/build/win32/kvm
make GCC=true ALT_BOOTDIR=/usr/local/jdk1.3.1
The built image is build/win32/kvm/bin/midp.exe
