Hi,
I managed to get a Hello World JNI app working, having both the Java and
C files in one project. The essential part was adding
-Djava.library.path . to the vm arguments, such that System.loadLibrary
found the lib file.
However, the preprocessor does not seem to understand the JNI variables
that are obligatory for the functions called by Java. They look like thi=
s:
JNIEXPORT jboolean JNICALL Java_function_name_in_Java_file
The first three words are marked as a warning:
Syntax error encountered in file: /home/hendrik/workspace/MSO/query.c at
offset: 282.
The offset is indeed the place of the first J in the file. Doesn=E2=80=99=
t the
preprocessor understand lines?
Any suggestions as to how to solve this? I added <java sdk>/include and
<java sdk>/include/linux to the include paths. The latter contains
jni_md.h, which contains
#define JNIEXPORT
#define JNIIMPORT
#define JNICALL
and is itself included from jni.h, which is included in query.h, which
is included in query.c.
Do I have to explicitly include jni_md.h?
TIA, H.
