freecad / freecad-libpack Goto Github PK

1.When debugging, fmt has an error. After checking, it is found that the debug configuration file is missing under the folder “LibPack-0.21-V2.10\lib\cmake\fmt”
2.Unable to perform Python/Native Debugging in VS，because .pdb files are missing in the following location，：
LibPack-0.21-V2.10\bin
LibPack-0.21-V2.10\DLLs
LibPack-0.21-V2.10\bin\Lib\vebv\scripts\nt

Could you improve these two problems ? Thank you!

My English is not good, please forgive me！

Hello
I am building Freecad with fmt last version , however MSVC is complaining from linking problem with 2017. Tried clean build but could not solve.

@WandererFan , I have no write permissions in https://github.com/FreeCAD /
FreeCAD-LibPack

Can you please give them to me so that I can create releases and upload there files?

Hi, dear FreeCAD Libpack maintainer, thanks for creating Libpacks for our convenience first! I have run into this error with the new FreeCAD Libpack for 020, the error occurs when I try to import a geometry or open a project file containing geometries, the screenshot of the error message please see below.

• I am working on a windows 10 machine building FreeCAD in debug mode, I have tested different compilers, MSVC++ 14.2x and MSVC++ 14.3x, and they result in the same error
• I have tested the Libpack 12.5.4 from https://github.com/apeltauer/FreeCAD/releases here, I did not run into the same issue while importing geometries.
  

Hello @scottmudge and @apeltauer and @wwmayer , FreeCAD 0.20 is stalled because of a lacking LibPack. I put Scotts' and apeltauer's latest LibPack here to work on it jointly.

apeltauer's LibPack (https://github.com/FreeCAD/FreeCAD-LibPack/releases/tag/1.0) is what we used fro FreeCAD 0.19. What needs to be done is
https://github.com/FreeCAD/FreeCAD-LibPack/blob/master/Requirements.txt

Scott, can you contribute the OCC part? Apeltauer failed because Netgen does not compile for him. Realthunder told me that with your LibPack (https://github.com/FreeCAD/FreeCAD-LibPack/releases/tag/2.0) Netgen compiles but is actually not fully usable. So we need to check Netgen in every case.
I remember that Netgen is always tricky. For FC 0.19 we fixed a version of Netgen and @wwmayer had a look what needs to be changed in FC to make the NetgenPlugin compiling. Then we never touched Netgen for the whole FC 019 series. I would do for 0.20 the same. @wwmayer , what do you think?

Concerning Qt, I will have a look at the weekend.

I work on Microsoft's C++ Standard Library implementation, and we regularly build popular open-source projects, including FreeCAD, with development builds of MSVC in order to find and fix regressions before they ship and cause problems for you. This also allows us to provide advance notice of breaking changes, which is the case here.

I recently merged microsoft/STL#4606, which is expected to ship in VS 2022 17.11 Preview 2. This PR removed non-Standard machinery that had been deprecated (with compiler warnings). Old versions of Boost used this machinery, but we worked with them to get Boost fixed, and this happened over 5 years ago.

However, FreeCAD-LibPack is still using a very old version of Boost that predates their fix. I observe that your latest release 2.11 contains Boost 1.67.0, which shipped on 2018-04-14 according to Boost Version History.

Can you update your copy of Boost, which will not only fix this specific issue, but also pick up years of correctness and performance improvements? The first fixed version was Boost 1.69.0 which shipped on 2018-12-12, but it would be best to upgrade to the latest release, Boost 1.85.0 shipped on 2024-04-15.

With the latest LibPacks the debug and release dlls of OCC have the same file names. This makes it very difficult to make a debug build of FreeCAD to use the debug build of OCC.

OCC's CMake build scripts used to have an option where for the debug build the suffix "d" was added to the dlls.

Is there any possible to support clang in windows platform? The obstacle is that boost requires a name like xxx-cl-xxx.dll.
Otherwise is there any build recipe or way to contribute?
