valuateData undefined

[ynscw]

Following up on my previous message, after resolving the earlier CMake configuration issues (thanks to your kind help!), I encountered one additional linking error during compilation:

CMakeFiles/solarzip.dir/solarzip.cpp.o: in function 'processCompression(...)':
solarzip.cpp:(.text+0x266d): undefined reference to 'valuateData(char const*, char const*, long*, compResult*)'

It appears that the function valuateData is called in solarzip.cpp, but its definition or declaration seems to be missing from the current codebase. I’ve searched through the repository and dependencies but couldn’t locate it. Would you be so kind as to advise where this function should be defined, or whether it might have been accidentally omitted?

Thank you for pointing out the issue. We have uploaded the missing file and hope this resolves the problem. Please feel free to reach out if you encounter any further issues.

[ynscw]

Thank you so much for your previous help — thanks to your guidance, I was able to successfully compile the codebase! I’m truly grateful for your time and support. However, I’ve encountered one issue during the make install step:
CMake Error at tools/sz3/include/qcat/cmake_install.cmake:92 (file):
file INSTALL cannot find "SolarZip/build/tools/sz3/include/qcat/QcatConfig.cmake": No such file or directory.
I’ve checked the build directory and source tree thoroughly but couldn’t locate QcatConfig.cmake. It seems this file is expected to be generated or provided for installation, but it’s currently missing. Would you be so kind as to advise: Whether this file should be auto-generated (and if so, under what conditions?), or Whether it was inadvertently omitted from the repository?

[Zedong-Liu]

OK! Please pull the latest version again — I hope this resolves the issue.

First and foremost, please allow me to express my deepest gratitude for your incredible patience and generous guidance throughout my setup process. Thanks to your kind help, I have successfully compiled and installed the SolarZip system — something I could not have achieved without your support. However, as a humble beginner in this field, I’ve encountered one final hurdle when trying to run a test compression command: build/bin/solarzip 3 REL 1e-3 SolarZip/data. The program outputs:
Error opening directory: No such file or directory
Segmentation fault (core dumped)
I suspect this may be due to either: The SolarZip/data directory not existing or being empty (I did check, but perhaps I misunderstood where sample data should be placed?), or A path issue in how I’m invoking the command. I sincerely apologize for troubling you yet again. My build directory is shown in the picture.

[Zedong-Liu]

SolarZip/data/example.fits is the provided sample data. Please use the absolute path to SolarZip/data/ as the input parameter — this should help avoid the error.

[ynscw]

I have already used the absolute path, but it still shows the same problem.

[Zedong-Liu]

Maybe you can check if there is a data directory under the SolarZip project directory. If it exists, use its actual absolute path as a parameter and replace the original SolarZip/data.

[ynscw]

Thank you very much for your reminder. I have tried as shown in the above picture, but the same error still occurred.

[Zedong-Liu]

Your error comes from the spaces in the folder name Image Compressed Demo. The program interprets this as multiple arguments, I suggest renaming it with underscores (e.g., Image_Compressed_Demo).

In addition, I recommend pulling and reinstalling the project, since I just updated some of the files.

[ynscw]

Following your earlier kind advice, I completely re-cloned and reinstalled the SolarZip repository from scratch. The build and installation now complete without errors, for which I’m deeply grateful. However, when I attempt to run a compression command, the program immediately exits with: Module not found Segmentation fault (core dumped) I’ve double-checked the input path, ensured the directory exists and contains valid data files, and even tried running with absolute paths — yet the issue persists.

[Zedong-Liu]

Sorry for the inconvenience caused. We’ve updated the code and fixed the issue with the missing Python module. It should work fine now, but feel free to let us know if you run into any other issues.

Thanks for your patience!

[ynscw]

Thanks to your generous help, I’ve now successfully run compression experiments with SolarZip — everything is working beautifully! As a beginner, I truly appreciate the time and care you took to support me through each step. Your work is not only technically impressive but also deeply inspiring, and your willingness to help others learn means more than I can express. Thank you again for your generosity, expertise, and encouragement. I’m truly grateful!
