Mergin projects, cant compile mocs_compilation

[Dariusz]

Hey

I'm at lost, spend 3h on it now and I can't get it moving.

I just merged a smaller project library in to larger app, just source copy/include. When I try to run it I get

app_autogen\mocs_compilation.cpp.obj] Error 2
Makefile2 [CMakeFiles\app.dir\all] Error 2
Makefile [all] Error 2

I have no idea what to do now, I was slowly adding classes 1 by 1 now, but I don't see any issue at all here.

Any idea how to troubleshoot it?

TIA

@Dariusz

Have you done a rerun qmake and a rebuild?

Ehem, are you really using Qmake?

Makefile2 [CMakeFiles\app.dir\all] Error 2

that rather sounds like CMake...

Yeah I'm using CMake...hmm I thought I placed tag in the topic for CMake here :- )

I'm going over CMakeFiles/app.dir /etc/etc now 1 by 1 trying to find some kind of cmake log that could tell me where it crashed....

Weird thing is, I managed to load half of the library-source, but when I try to say extend one of classes I get an error too... o_o

@aha_1980 Ok I think I found it... it was... WINDOWS PATH LIMIT! Yay....... How on earth do I fix it? O_O

Hi Wow. it must be a somewhat nested structure to hit the limit.
Anyway, if Windows 10, there is an opt-in option

section Maximum Path Length Limitation

I've set the group policy to be long paths, as I'm on w10Pro but still did not work. I ended up having to shorten my folder names :- (((( Apparently in order for long path to be used the application has to use it itself, its not default implementation or something like that :- (.

Hi,

Out of curiosity, how long are you paths ?

Weird, I just did check on one of longer ones, it was around 140 chars... + so this is even weirder... how did I hit path limit o.O

[SGaist]

Encrypted disk ?

[Dariusz]

Nope don't think so. I guess the build/debug/CMake.xxxx etc etc might add quite a few more chars, so the files in src are fine but the generated cmake path is too long due to all of them adding up somehow?

[SGaist]

Did you try to build your project directly from a command prompt ?

[Dariusz]

Hey

Nope not yet. Will try it, just need to learn it :- )
