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:]':

Though, it looks like it is compiling NSJavaVirtualMAchine fine:
gcc NSJavaVirtualMachine.m -c \

from NSJavaVirtualMachine.m:25:
C:/GNUstep/GNUstep/Local/Library/Headers/Foundation/Foundation.h:47:34:
warning:

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,
Tim
