JNI - Cannot open include file: 'jni_md.h

[rav1]

I have been trying with no avail, to compile my c++ program with the path in visual express cmd, I have tried diff ways but still shows errors. I have searched diff forums but no help so far.

The following is the code that I am using

cl -I"c:\program files\java\jdk1.6.0_06\include" -I"c:\program files\java\jdk1.6.0_06\include\win32" -I"." -MT -LD HelloWorld.cpp -FeHelloDLL.dll


where my path is C:\Program Files\Java\jdk1.6.0_06\include

If anyone has had this before and solved it please let me know

Much appreciated

if you haven't got it then open up notepad, paste this lot into it and save it as a file called sdkvars.bat in whatever folder you wish to place your command line programs:

@Set Path=C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin;C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727;C:\Program Files\Microsoft Visual Studio 8\VC\bin;C:\Program Files\Microsoft Visual Studio 8\Common7\IDE;C:\Program Files\Microsoft Visual Studio 8\VC\vcpackages;%PATH%
@Set LIB=C:\Program Files\Microsoft Visual Studio 8\VC\lib;C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Lib;%LIB%
@Set INCLUDE=C:\Program Files\Microsoft Visual Studio 8\VC\include;C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\include;%INCLUDE%
@Set NetSamplePath=C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0
@Set VCBUILD_DEFAULT_CFG=Debug^|Win32
@Set VCBUILD_DEFAULT_OPTIONS=/useenv
@echo Setting environment to use Microsoft .NET Framework v2.0 SDK tools.
@echo For a list of SDK tools, see the 'StartTools.htm' file in the bin folder.
Now go into the folder and run the .bat file. Hopefully, you'll be able to run csc.exe after you've done this.

thanks for that, the thing is, I have got both the jni.h and jni_md.h files, so I dnt know what is the problem with my compiling method.

Have you tried adding %JAVA_HOME%\include and %JAVA_HOME%\include\win32 in INCLUDE environmental variable.
so that you can simply type on windows prompt

cl my.c -Fe my.dll

I have tried it but nothing, I changed the the jni.h to <jni.h> and it workedm but it cant find jni_md.h now

I had faced a similar issue with my system before when I was working on program. I found a solution at that time and hope this might can help you out. For that in Visual C++ you will need to click on Tools and then in that search for option. Now you have to go in Directories and then add the files in jdk\include AND jdk\include\win. You must add them to the list of directories.
