Problems building JIGS on msys/mingw

[Tim Kack]

Hi all,

I was thinking of building JIGS on my Windows 7 machine, but I have run into issues.

I am using yesterdays SVN of everything (monthly rebuild of my windows gnustep installation).

I have not yet updated to get rid of "GNUstep/Local/Library/Headers/Foundation/Foundation.h:47:34: warning:

 Foundation/NSCalendar.h: No such file or directory" - but I do not think that matters in this case.

Problems:

1. () characters in PATH and CLASSPATH - really nothing that is GNUstep specific but rather msys issue. I document them here if someone is searching the ML for some reason:

On Windows 7 some applications are installed in /c/Program Files (x86)/. The () will break the bash scripts.

Solution: Remove these path segments from PATH and CLASSPATH.

2. Compilation generates some warnings - can these be ignored?

JIGSProxyIMP.m:355: warning: implicit declaration of function 'alloca'

3. It fails to link due to undefined references:

Creating library file: ./obj/libgnustep-java.dll.a

obj/libgnustep-java.obj/NSJavaVirtualMachine.m.o: In function `+[NSJavaVirtualMa

chine startVirtualMachineWithClassPath:libraryPath:]':

ndefined reference to `_imp__JNI_CreateJavaVM@12'

Though, it looks like it is compiling NSJavaVirtualMAchine fine:

gcc NSJavaVirtualMachine.m -c \

              -MMD -MP -DGNUSTEP -DGNUSTEP_BASE_LIBRARY=1 -DGNU_GUI_LIBRARY=1 -D

                 from NSJavaVirtualMachine.m:25:

C:/GNUstep/GNUstep/Local/Library/Headers/Foundation/Foundation.h:47:34: warning:

 Foundation/NSCalendar.h: No such file or directory

I checked jni.h and the function is exported properly:

_JNI_IMPORT_OR_EXPORT_ jint JNICALL

JNI_CreateJavaVM(JavaVM **pvm, void **penv, void *args);

_JNI_IMPORT_OR_EXPORT_ jint JNICALL

JNI_GetCreatedJavaVMs(JavaVM **, jsize, jsize *);

What am I missing? Any help regarding this would be most appreciated.

Cheers,
