win10 64bit native code throw Invalid sizeof type 4 exception

[ben0x007]

I am using eclipse and run msoffice demo in JDK1.7, but throw java.lang.IllegalArgumentException: Invalid sizeof type 4, and I saw the Native source code: BOOL_SIZE = sizeof(TYPE_BOOL)
can not calculate "bool" size in win10 64bit。

Please provide the version of JNA you are using and provide steps to reproduce and the full stack trace you are seeing. Thank you!

I just wasted about two hours just to find eclipse as unintuitive as I remembered. Please provide detailed steps to reproduce your problem starting from a clean git checkout and then each step that is needed.

From my perspective there is no problem:

• I used my git checkout, switched to tag 4.2.2
• failed to make the project workable with the existing eclipse project files
• restartet and only imported the msoffice sample project
• removed the project dependencies and replaced them with references to the jna.jar and jna-platform.jar in dist folder
• I successfully ran the MSOfficeWordDemo from eclipse

Dear Matthias, I apologize for the time you had to waste:( I can confirm now that clean checkout of release 4.4.2, indeed, works fine. Problems only occur when running from master and referencing both projects (jnalib and platform) and jars in the build path. I realize now it was a bad idea.
Thanks for your help - and sorry for your wasted time.

@elseiver no problem - if you want to work with master, just run

ant dist

from the jna base directory. Asuming ant and the JDK are correctly installed (you may have to adjust JAVA_HOME to point to the JDK), this will rebuild the dist files and create a 4.3.0-SNAPSHOT version of the dist files.

To give this some perspective we are running nightlies at work in production, as we need the newer COM bindings.
