Hi,
As part of my evaluation of Directory Opus (which looks sooooo promising) I am getting started on understanding plugins and what they could do for me.
I thought to start I would just compile the 'rar_sample_vfs_plugin'. Well always try the lucky, easy, way first; looks like I am out of luck today
Could you please advise what development platform is good to use? And any fancy settings needed.
The rar.rc file says it was generated by 'Microsoft Visual C++' so I thought to throw it at that products sucessor 'Visual Studio' and my installed version is 2022
With only the 'Desktop Development with C++' workload.
Well, 190 errors and 31 warning later it not going to work Out-Of-The-Box
As there is no project or solution file in the downloaded reasouces I suspect you are not using VS
The errors are mostly
"cannot convert from 'LPWSTR' to 'LPSTR' "
"argument of type "LPWSTR" (aka "wchar_t *") is incompatible with parameter of type "LPSTR" (aka "char *")
but one "'DWL_USER': undeclared identifier " suggests a missing component of some type.
Use Visual Studio, and make sure the project is set to Use Unicode Character Set under Properties / Configuration Properties / Advanced for the DLL file.
Leo,
Thanks for this input - sorry for the delayed response but I guess you know how 'other-things' can get in the road of a project.
Anyway I also needed to add "C++ MFC for latest v143 build Tools (x86 & x64)"
Now it is complaining Error LNK2028 unresolved token (0A000151) "extern "C" wchar_t * __cdecl PathFindNextComponentW(wchar_t const *)"
then ditto for PathAppendW, PathRemoveFileSpecW and PathFindFileNameW
followed by the same set but error "Error LNK2019 unresolved external symbol"
I am sorry but I haven't touched C++ for over 25 years and have recently been using .NET which seems to have a very different 'framework' structure.
In short I am having trouble turning my head around to what this might be missing.
Also I see the 'Rar plugin' code is over 15 years old; so anything I install/import today could easily be incompatible with the past.
Could you please 'hum-a-few-bars' of the environment this great app is developed in, with what base library sets etc, so maybe I can stop bothering you at every step.
Jon,
I am aware of what the error means.
My point is that I am trying to compile the sample code in opus_sdk.zip from Download Resources - Directory Opus Self-Service Support
This is completely untouched by me - just OOB this does not compile.
My question is what environment is needed to get it compile. What libraries are you assuming are installed?
JC
