UnsatisfiedLinkError in imageformats

[boggiz]

Hello,

I have tried to execute 0.3.3 release today but i have this exception error :

Yet the paths in windows and mcf2pdf.bat are good i not understand where is my error !
Could you help me ?
Thanks a lot

[albrechtf]

Could you please check if the file C:\Program Files\Photocite by CEWE\imageformats\qwebp.dll exists? If not, please check (and report) which version of the CEWE software you have installed. Thanks!

[albrechtf]

Oh, and please paste the output of the command java -version. It may be that you have a 32bit Java on a 64bit Windows (or the other way round)...

[boggiz]

Here is some snapshots:

1. The file exists :
   

2. CEWE version
   

3. Java Version
   

Thanks a lot for your intervention

[albrechtf]

I was able to reproduce this (biggest problem was to get a windows machine for testing ;-)). Please check with latest release (https://github.com/albrechtf/mcf2pdf/releases/latest), and close this issue if fixed. Thanks!

[boggiz]

Thank you very much for your speed. I will test this new release later this week.

Did you replace your libwebp.dll? I hope you backed it up :-) The libwebp.dll is expected to be directly in the installation directory of CEWE (and is NOT identical to qwebp.dll). Could you please paste your full error message from the first try? The full classpath listed there would give a hint where the DLL has been searched for. Thanks!

[rbodziony]

removed and reinstalled 6.25

Finally, CEWE seems to react to Mcf2Pdf :-) With 6.2.4, it should work - I installed it just two days ago on a Windows machine. I have no clue why they removed that library from 6.2.5...

As a workaround, you could manually download libwebp.dll and copy it to the installation directory of CEWE - it is a free open source library, you can e.g. download it here: http://www.kopf.com.br/kaplof/libwebp-dll-binaries-for-windows-download-missing/

I will check if the licenses are compatible and perhaps include binaries of this DLL for Windows and Linux in the Mcf2Pdf package.

[boggiz]

I am on Windows 7 (64b) and I encountered this dll problem this morning. I downloaded it and installed it in Windows \ System32.
I converted a file without problem with the CEWE 6.02.04 release which is the latest available in France.
Thanks again for your efficiency

[boggiz]

Here is the link for the dll : https://fr.dll-files.com/libwebp.dll.html

[albrechtf]

Libraries included for Windows x64 and Linux x64. For Mac OS X, you should install the libwebp package into the system (see Release Notes).

Feedback is appreciated; please close the issue if it is now fixed for you. Thanks!

[rbodziony]

hi
so good is is now starting working so you can close this issue
2nd is crashing during processing ( i ll open new issue)
Thx

[boggiz]

Hello,
I think you need to provide 2 dll for Windows one 32bits and the other in 64bits because with this version 0.3.4 I have a new error:

When I analyze the dependency hierarchy of your libwebp.dll an error pops up stating that the MSVCR110.DLL dll does not exist on my Windows 7 64-bit sp1 system:

The dll I mentioned in my previous post is a 64b as indicated in the snapshot below:

It is therefore necessary to put the 2 dll in the java file and choose the one to use during the execution ...
Thank's

[aschue]

I had the same issue on Windows 10 (64bit), using the 0.3.4 release.
The mcf software I am using is dm-Fotowelt 6.3.1 (x64), and Java version 1.8.0_161.

I could fix it by downloading the library from the website that @boggiz posted earlier

Here is the link for the dll : https://fr.dll-files.com/libwebp.dll.html

, and copying it into the installation directory of the mcf software. I had to use the 32 bit version for it to work, though.

[bertramakers]

For Mac OS X, you should install the libwebp package into the system (see Release Notes).

Ran into the same issue on macOS. Installed webp using Homebrew and now have cwebp and dwebp available as commands in the Terminal.

Also have a libqwebp.dylib file in the imageformats directory.

Still getting the following error:

[rbodziony]

Can you check this https://github.com/rbodziony/mcf2pdf/releases/tag/0.3.6 version with enabled debug and provide it ?

[bertramakers]

Do I have to build it myself to enable debugging or is it enabled by default in the provided binaries?
I tried running the Linux binary from the link you provided but had to convert the line endings in the script first, following the steps provided here: https://stackoverflow.com/a/23097540
Got the script running but still got the same error though. No extra debugging output printed.

If I have to build it myself, can you provide some instructions? I'm not familiar with building Java applications.

[rbodziony]

Hmm can you show how you run it ?
To enable debug log use -d switch

[rbodziony]

Also pls show output how you installed webp and version cwebp and dwebp
