Hello ! I am trying to make a build of GCC 4.2.2 with GCJ for MinGW. I first tried with : ../gcc-4.2.2/configure --enable-languages=c,c++,java -v --enable-optimize --prefix=/mingw --oldincludedir=/mingw/include --enable-threads --disable-nls --disable-win32-registry --disable-shared --without-x it compiled without any problem but when I try to launch gcj it complains about the lack of libgcj, and effectivly libgcj is not present. No problems with gcc or g++. so I tried to add --enable-libgcj and then I now have problems at the compilation time. the errors begin like that : make[4]: Entering directory `/D/SVN/compil/i686-pc-mingw32/libjava/classpath/tools' mkdir -p classes/gnu/classpath/tools/giop/grmic/templates mkdir -p classes/gnu/classpath/tools/rmi/rmic/templates mkdir -p classes/gnu/classpath/tools/appletviewer mkdir -p classes/gnu/classpath/tools/jarsigner mkdir -p classes/gnu/classpath/tools/keytool cp ../../../../../gcc-4.2.2/libjava/classpath/tools/gnu/classpath/tools/rmi/rmic/templates/*.jav classes/gnu/classpath/tools/rmi/rmic/templates cp ../../../../../gcc-4.2.2/libjava/classpath/tools/gnu/classpath/tools/giop/grmic/templates/*.jav classes/gnu/classpath/tools/giop/grmic/templates cp ../../../../../gcc-4.2.2/libjava/classpath/tools/gnu/classpath/tools/rmi/*.txt classes/gnu/classpath/tools/rmi/ cp ../../../../../gcc-4.2.2/libjava/classpath/tools/gnu/classpath/tools/giop/*.txt classes/gnu/classpath/tools/giop/ /D/SVN/compil/gcc/gcj -B/D/SVN/compil/i686-pc-mingw32/libjava/ -B/D/SVN/compil/gcc/ -encoding UTF-8 --bootclasspath '../lib':'../lib/glibj.zip' --classpath . -C -d classes ../../../../../gcc-4.2.2/libjava/classpath/tools/gnu/classpath/tools/*.java ../../../../../gcc-4.2.2/libjava/classpath/tools/gnu/classpath/tools/*/*.java ../../../../../gcc-4.2.2/libjava/classpath/tools/gnu/classpath/tools/*/*/*.java ../../../../../gcc-4.2.2/libjava/classpath/tools/gnu/classpath/tools/AbstractMethodGenerator.java:0: error: Can't find default package 'java.lang'.
