Python errors after building from master

Postby falviani » Wed Apr 14, 2021 9:45 pm

Hi all,

I cannot include the usual version info here since my build is broken. :(

I just built from the latest master (as of 1PM CDT 14Apr21) using the latest VS2019. I have Python 3.8.9 installed, but the CMake config shows that it's pointing to the versions in the libpack. The build was successful but when I try to launch the app I get the following errors (in order):

Can anybody suggest fixes for these?

Thanks in advance,
Frank

You don't need a separate Python installation. The LibPack provides everything you need.
build was successful but when I try to launch the app I get the following errors (in order):
Now you need to extend the PATH environment variable by the LibPack's bin directory. You don't need to do this system-wide but you can do this within VS. Therefore right-click on the FreeCADMain target in the Solution Explorer and go to Properties. There switch to Debugging and write this to the environment section:

Code: Select all

FREECAD_LIBPACK_BIN=Your_path_to_the_Libpack\bin
PATH=%FREECAD_LIBPACK_BIN%;%PATH%

I followed your instructions, I believe. The configuration in VS looks like this:

But at least I'm getting new errors (sigh):

But at least I'm getting new errors (sigh):
Instead of getting a failure that Qt dlls cannot be found you get that an entry point isn't found. This looks like a binary incompatible Qt version is loaded. If you press F5 inside VS you should get some hints (see VS's Output window) about where the Qt dlls are located.

Alternatively you can copy the content of the LibPack's bin directory to FreeCAD's bin directory. This way the Qt dlls are in the same directory as FreeCADBase.dll, ... and then the correct version is loaded.
I'm getting tired.
Don't give up!

Here's the output window from VS2019:

Code: Select all

This may cause incremental build to work incorrectly.

At the end of the build came this cheerful message:

So I copied the entire contents of the libpack bin directory into the FreeCAD output's bin directory (replacing files with the same names). So, attempting to launch Freecad.exe yields this:

I MUST have something truly weird about my machine/dev configuration. I can't believe the Master branch is in this state :(

This can be fixed by setting FREECAD_COPY_PLUGINS_BIN_TO_BUILD with CMake-gui and then configure and generate.
This should move the necessary files, no need to build in VS.

Here's the output window from VS2019:
That's not what I meant. If you press F5 to start debugging you should see the list of loaded dlls and their absolute paths. Then you should be able to see where are the incompatible dlls are located.

You have almost reached the goal. In the bin directory there must be a directory platforms with the qwindows.dll.

SRogan,

Unfortunately there are NO freecad copy options in CMake:

So I'm not sure how I would do that. Putting 'copy' into the search box shows nothing at all.

Thanks for the idea - the instructions on the site explicitly call to set all 3 copy options on, but they no longer seem to exist.

WMayer,

I did use F5 to start debugging. It gave the errors I showed in the VSOutput then stopped with an 'access denied' error.

If you run configure again does it show up?
