macos java.lang.UnsatisfiedLinkError image not found

[jeff6times7]

Sorry, I didn't find any existing topic in this JCEF forum for my problem. I also didn't find any "inclusion" instructions in the source tree. Can you review my topic and let me know what you think? I must be doing something wrong because the test app is working fine. I just can figure out why my attempt to incorporate the jcef app's files into mine is failing.

I cloned the repo and my wc is at 1fda5d8f948670d08ef86bc4e8637b8581995ce9, which Marshall committed 2018-07-24.

Using the macos instructions, I successfully created the Release and Debug products for the project. Both product's app opens just fine. When I run the JavaAppLauncher from the command line I can see debug output.

So far, so good.

Then I reviewed the content of jcef_app.app and saw how that app is built by src/build.xml. Since I make my app with ant, I figured I hit gold. I made a simple edit to build.xml to remove the unused component in the java.library.path (which is $APP_ROOT/Contents/Frameworks/Chromium Embedded Framework.framework/Libraries). Then I built again and saw change reflected in the app's Info.plist. The app still opens.

Very, very good, so far.

I ran the following commands to copy the "support" files from jcef app to my app. Let $mytop be the path to my app's Contents folder and let $jceftop be the path to jcef_app.app/Contents folder for the Debug product. I get a similar error when I use the Release product but with the Release product I don't see as much error detail.

rm -fr "$mytop/Frameworks"
cp -pr "$jceftop/Frameworks" "$mytop"
cp -pr "$jceftop/Resources"/* "$mytop/Resources"
cp -pr "$jceftop/Java"/* "$mytop/Java"

Then I execute the abbreviated java command for my app so I can see the logging output on the console:

cd $mytop
java -Djava.library.path="$mytop/Java" -jar "$mytop/Java/my.jar"

Even if I reinstitute the precise java.library.path specified in the original Info.plist, I get the same error:

java -Djava.library.path="$mytop/Java/:$mytop/Frameworks/Chromium Embedded Framework.framework/Libraries" -jar "$mytop/Java/my.jar"

When I execute the AbstractAction that tries to create the objects I need (I got the code from MainFrame.java in the details tests), I see this error on the console output.

I thought it would be easy such that I just didn't have to file that was needed by ld.

If you're not running via JavaAppLauncher (or similar exe inside the app bundle) then it's probably confused about the meaning of @rpath. See https://bitbucket.org/chromiumembedded/ ... t-35461901

[jeff6times7]

You are correct. When I open the app or execute JavaAppLauncher (which I believe is nearly the same thing), then the browserUI displays. I'll read the page you cite and I'm sure things will go well. Much obliged.
