After moving project folder into a different path, QT keeps looking for files to include into the old path.

mvreenv

@JonB I tried this and it doesn't find any matches. I tried running qmake on another repository (https://github.com/taiya/starlab-mcfskel) that adds to starlab and it gives the same error, at this point I think the problem probably lies inside qmake

mchinand

It looks like the .pro project files reference the .prf files relative to PWD variable which seems fine (see example below). All the references to .prf files don't use 'qmake -set ...' but for those that do, you can check what those variables get set to.

mvreenv

@mchinand I tried doing this

message($$PWD)
system(qmake -set STARLAB       $$PWD/starlab.prf)
message($$[STARLAB])

and I get this

Project MESSAGE: C:/builds/starlab/core
Project MESSAGE: C:/Users/marin/Documents/UNIPI/TESI/Workspace/starlab/core/starlab.prf

The PWD value goes back to the old path when there's "qmake -set"

mchinand

I've never used the -set option of qmake but looks like it makes the settings persist between calls. It seems like it should update the variables when you call it again. Run the following and see if your (old) paths are there.

qmake -query

I don't see a way to unset variables (I would have thought setting it again would overwrite it). The documentation says these values are stored in a QSettings but I'm not sure where exactly (probably somewhere in your AppData folder somewhere) What version of Qt are you using? Perhaps upgrade to a newer version. You may want to replace those qmake -set lines with just plain variable assignments but you may have it in additional files. Maybe moving all the qmake -set calls to your top-level .pro file will help.

mvreenv

@mchinand the -set option was used in the repository I cloned.

I tried running system(qmake -query) but it doesn't show anything in the output.

I looked into the <user>\AppData\Roaming\QtProject\ and there's a QtCreator.ini file but it only stores information for the configuration of Qt Creator.

So I tried adding this after all the system(qmake -set) calls:

for(var, $$list($$enumerate_vars())) {
    message($$var)
    message($$eval($$var))
}

and got the value of QMAKESPEC which is "A system variable that contains the full path of the qmake configuration that is used when generating Makefiles. The value of this variable is automatically computed." (https://doc.qt.io/qt-5/qmake-variable-reference.html#qmakespec). I then followed the path and opened the qmake.conf file found there but it doesn't store any of the set values with the system(qmake -set) calls.

With the listing of all the variables and their value I got this:

PWD = C:/builds/starlab/core
OUT_PWD =  C:/builds/starlab/core
_PRO_FILE_PWD_ = C:/builds/starlab/core

And when I try to search for "STARLAB" or "EIGENPATH" (which should've been set to something) in the output there are no results. I also tried searching for the old path but still no results.

I am using Qt 5.12.12, which I also uninstalled and reinstalled to try and solve this problem, with no success.

Since it's Windows, take a look at the registry.

mchinand

You can do it outside of your project file. Here's a test I did:

C:\Qt\5.14.2\msvc2017_64\bin> .\qmake -set ASDFTESTVARIABLE XYZ
C:\Qt\5.14.2\msvc2017_64\bin> .\qmake -query
ASDFTESTVARIABLE:XYZ
QT_SYSROOT:
QT_INSTALL_PREFIX:C:/Qt/5.14.2/msvc2017_64
QT_INSTALL_ARCHDATA:C:/Qt/5.14.2/msvc2017_64
QT_INSTALL_DATA:C:/Qt/5.14.2/msvc2017_64
QT_INSTALL_DOCS:C:/Qt/Docs/Qt-5.14.2
...

C:\Qt\5.14.2\msvc2017_64\bin> .\qmake -set ASDFTESTVARIABLE ABC
C:\Qt\5.14.2\msvc2017_64\bin> .\qmake -query
ASDFTESTVARIABLE:ABC
QT_SYSROOT:
QT_INSTALL_PREFIX:C:/Qt/5.14.2/msvc2017_64
QT_INSTALL_ARCHDATA:C:/Qt/5.14.2/msvc2017_64
QT_INSTALL_DATA:C:/Qt/5.14.2/msvc2017_64
QT_INSTALL_DOCS:C:/Qt/Docs/Qt-5.14.2
...

And there is a qmake -unset option

C:\Qt\5.14.2\msvc2017_64\bin> .\qmake -unset ASDFTESTVARIABLE
C:\Qt\5.14.2\msvc2017_64\bin> .\qmake -query
QT_SYSROOT:
QT_INSTALL_PREFIX:C:/Qt/5.14.2/msvc2017_64
QT_INSTALL_ARCHDATA:C:/Qt/5.14.2/msvc2017_64
QT_INSTALL_DATA:C:/Qt/5.14.2/msvc2017_64
QT_INSTALL_DOCS:C:/Qt/Docs/Qt-5.14.2

@SGaist the values that were set with qmake -set and had the old path were indeed in the windows registry, under Computer\HKEY_CURRENT_USER\SOFTWARE\QtProject\QMake.

I deleted them and it seems to have fixed the issue. Thank you all!

mchinand

I just edited my recent reply, there is an qmake -unset option that removes the variable. Removing it in the Registry certainly works though too.

mvreenv

@mchinand yeah I already had deleted them when I saw your reply, good to know about qmake -unset for the future, thank you!

mvreenv

And now I have another issue, after deleting the windows registry variables with regedit, it doesn't seem like qmake is able to initialise and assign them. After the qmake -set calls if I write this in the core.pro file

message($$PWD)
message($$[STARLAB])
message($$[NANOFLANN])

I get this output:

Project MESSAGE: C:/builds/starlab/core
Project MESSAGE: 
Project MESSAGE:

And even by running qmake.exe -query in C:\Qt\5.12.12\msvc2017_64\bin the variables don't show up.

mvreenv

I resolved the issue by manually setting the variables with qmake in commad line in the C:\Qt\5.12.12\msvc2017_64\bin folder and checking in the Windows Registry if they were correctly initialised.

@mvreenv hi Were you able to implement the 3D shape skeleton?
I also have problems in this field, I can ask you for help
