Client7z was unable to unpack a long header file

[kanejons]

Tell me, I'm faced with the fact that I get an error in this place. I guess it's because of the number of characters, but I'm not sure. It is in the archive itself that folders and files with a long name are located. That's what I think is wrong, but I'm not sure. Here is the archive folder inside: C:\Users\ssssssssss.s\Desktop\test\hkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkj.

 CMyComPtr<ISequentialOutStream> outStreamLoc(_outFileStreamSpec);
    if (!_outFileStreamSpec->Open(fullProcessedPath, CREATE_ALWAYS))
    {
      PrintError("Cannot open output file", fullProcessedPath);
      return E_ABORT;
    }

Tell me what could be the matter?if required, I can attach the archive itself

-DZ7_LONG_PATH is requred for long paths:

CFLAGS = $(CFLAGS) -DZ7_LONG_PATH

also it's better to enable unicode, if it was not enabled in another places:

CFLAGS = $(CFLAGS) -DUNICODE -D_UNICODE

Okay, where do I turn it on?

[Igor Pavlov]

for command line you can edit makefile.
if you use VS gui program, you can have Unicode option and you can define -DZ7_LONG_PATH in some project options.

[kanejons]

I have unicode installed. I use qt and cmake to run. And I can't figure out where to write this parameter -DZ7_LONG_PATH

[Igor Pavlov]

what C++ compiler do you use?
unicode is defined via -D switch.
All C++ compilers support -D switch to define macro for C++/C files.

Look some makefiles for different projects, and probably you will see -D examples there.

[kanejons]

I am using the MSVC2019 compiler. -D found it in another place.

Good afternoon, how else can I insert a long path? Is it only through the makefile or is there another way in the code?

[Igor Pavlov]

-DZ7_LONG_PATH must solve problem with long paths.
Use latest source code: 7-Zip 23.01
And compile all C++ files of project with -DZ7_LONG_PATH.
