[Xapian-discuss] java bindings 1.0.0 - jni.h not found

[Martin Kuen]

hi,

thanks for telling me about config.log.
Yes the "jni.h" file is found but not picked up.
from "configure.log":
- configure:15431: checking for jni.h in /usr/lib/jvm/java-
1.5.0-sun-1.5.0.11/include
- configure:15442: g++ -c -g -O2
-I/usr/lib/jvm/java-1.5.0-sun-1.5.0.11/include
conftest.cpp >&5
- In file included from conftest.cpp:1:
- /usr/lib/jvm/java-1.5.0-sun-1.5.0.11/include/jni.h:27:20: error: jni_md.h:
No such file or directory

I found the problem and the java-binding compiles now with "make check" and
passes the test.

The problem is that the header-file "jni.h" includes another file called
"jni_md.h" (#include "jni_md.h"). This file is in a system-specific
subdirectory of "path-to-jvm/include", that is called sth. like solaris,
linux or windows.
read: http://java.sun.com/products/jdk/faq/jni-j2sdk-faq.html#jni_md
The the configure script has to add this subdirectory to the buildpath as
well.

To make it work for me I simply copied the "jni_md.h" file into the parent
directory ("path-to-jvm/include").
Configuring works and the "make check" is fine as well.

Thanks to all of you for all the quick replies.


Cheers,

Martin
