Native gcj: --resource does not work

[Jens Fransson]

Hello everyone!

Currently I am trying to get a native, statically linked executable to
run under Windows. I encounter trouble when referencing resources
(properties files, that is) that are supposed to be statically linked
into the executable.


The environment I am using is MinGW with GCC 3.4.2 (mingw special).
More precise the result of "gcj -v":

Reading specs from C:/program/mingw/bin/../lib/gcc/mingw32/3.4.2/specs
Reading specs from C:/program/mingw/bin/../lib/gcc/mingw32/3.4.2/../../../libgcj.spec
rename spec lib to liborig
Configured with: ../gcc/configure --with-gcc --with-gnu-ld --with-gnu-as --host=mingw32 --target=mingw32 --prefix=/mingw
 --enable-threads --disable-nls --enable-languages=c,c++,f77,ada,objc,java --disable-win32-registry --disable-shared --e
nable-sjlj-exceptions --enable-libgcj --disable-java-awt --without-x --enable-java-gc=boehm --disable-libgcj-debug --ena
ble-interpreter --enable-hash-synchronization --enable-libstdcxx-debug
Thread model: win32
gcc version 3.4.2 (mingw-special)


I am building the application by the following commands:

gcj -v --resource com.fransson.app.myprog.localization.Language_de.properties -o Language_de.o -c com/fransson/app/myprog/localization/Language_de.properties
gcj -v --resource com.fransson.app.myprog.localization.Language_en.properties -o Language_en.o -c com/fransson/app/myprog/localization/Language_en.properties
gcj -v --resource com.fransson.app.myprog.localization.Language.properties -o Language.o -c com/fransson/app/myprog/localization/Language.properties

gcj @java-files.txt Language_de.o Language_en.o Language.o -v -mwin32 -Dfransson.debug=true -o MyProg.exe --main=com.fransson.app.myprog.MyProgLauncher


Compiling seems fine, but when trying to load a properties file via ResourceBundle.getBundle()
I get the following error:

C:\temp>MyProg.exe
Launching MyProg.

C:\temp>

This error does not occur when the properties files are available
externally in the classpath. It seems that gcj cannot find its
properties files within the executable, although they are linked in:

C:\temp>nm MyProg.exe | grep properties
00430440 t __GLOBAL__I_com_fransson_app_myprog_localization_Language.properties_00000000_912

Is this a bug in gcj? Am I missing anything?
Any help would be greatly appreciated!

Cheers,
Jens
