I can create java executables for Ubuntu. However, when I try to use MinGW I cannot get an exe created with gcj to correctly execute. The program seg fault. I reinstalled MinGW (using MinGW-5.1.4.exe), libiconv and gdb 30 minutes ago and re-ran the test java program: public class Test { public static void main(String args[]) { System.out.println("This is a test."); } } Here is the version information: >gcc -v Reading specs from f:/mingw/bin/../lib/gcc/mingw32/3.4.5/specs Configured with: ../gcc-3.4.5-20060117-3/configure --with-gcc --with-gnu-ld --wi th-gnu-as --host=mingw32 --target=mingw32 --prefix=/mingw --enable-threads --dis able-nls --enable-languages=c,c++,f77,ada,objc,java --disable-win32-registry --d isable-shared --enable-sjlj-exceptions --enable-libgcj --disable-java-awt --with out-x --enable-java-gc=boehm --disable-libgcj-debug --enable-interpreter --enabl e-hash-synchronization --enable-libstdcxx-debug Thread model: win32 gcc version 3.4.5 (mingw-vista special r3) >ld -v GNU ld (GNU Binutils) 2.19.1 I used make (after copying and renaming mingw32-make.exe as make.exe) and this makefile that I created and successfully used with the Ubuntu version of gcj: %: %.java gcj -Wall -O3 --main=$@ -o$@ $^ CheckerBoardViewer: CheckerBoardViewer.java CheckerBoardComponent.java gcj -Wall -O3 --main=$@ -o$@ $^ >gdb Test GNU gdb 5.2.1 Copyright 2002 Free Software Foundation, Inc.
