Can't find dependent libraries #17

Closed JellevanAbbema closed 3 years ago

JellevanAbbema commented 3 years ago

So this is most likely a problem on my side but right now I'm at a loss and hope someone here can help me out.

When calling loadLibraries() I get an 'UnsatisfiedLinkError' with the following message: "C:\Users\ME\AppData\Local\Temp\devolay-natives18438449399369710411.dll: Can't find dependent libraries"

I had everything working with this library about half a year ago (with version 1.2.0), I had a small break and I recently started everything up again and updated all dependencies (and moving to version 2.0.0 of this library) but right now it's not working. I also changed my main drive and reinstalled most programs. I think it might be either my new C: drive or the new library version that caused this but I'm not sure.

Some more details: Windows 10 64bit NDI Runtime 4.5.1 installed JDK 14.0.2 (but also tested with OpenJDK 11.0.9)

This is a happy coincidence, because I just was having an identical issue. I reinstalled my OS, and I was also getting that "Can't find dependent libraries" message, and was working on a fix. It turns out that the builds generated by the Github CI have a somewhat hidden dependency on some MinGW dlls.

I am looking into a proper fix for this, but a temporary solution is to put these two dlls into your working directory, or onto your PATH. devloay_extra_dependencies.zip (These files are "/usr/lib/gcc/x86_64-w64-mingw32/9.3-win32/libgcc_s_seh-1.dll" and "/usr/lib/gcc/x86_64-w64-mingw32/9.3-win32/libstdc++-6.dll" from a MinGW linux install, in case you want to retrieve them yourself)

I'll leave this issue open to track a proper fix for this. It looks like G++ has an option to bundle these dlls with a single binary, but it doesn't seem to be working with the rest of my build configuration.

Thank you for the quick response! The files you provided do indeed fix the issue, thank you so much! Hope you find the propper fix.

A fix for this has been released in v2.0.1. Thanks for reporting!
