visual studio cant work with more than 260 character-length variables

[kasra]

Hello every one,

I’m trying to build SOFA from source code, but the visual studio is throwing this error:

Parvin, [27.03.21 20:05]
Severity  Code  Description  Project  Project Rank  Path  File  Line  Column  Category  Source  Suppression State  Tool
Error  MSB3491  Could not write lines to file "x64\Release\SofaGeneralObjectInteraction_SofaGeneralObjectInteraction_relocatable_install\SofaGene.E29F4CB7.tlog\SofaGeneralObjectInteraction_SofaGeneralObjectInteraction_relocatable_install.lastbuildstate". The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters.  SofaGeneralObjectInteraction_SofaGeneralObjectInteraction_relocatable_install  16  C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\VC\VCTargets  C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\VC\VCTargets\Microsoft.CppBuild.targets  321  5    Build    WriteLinesToFile

Here is a screenshot of the visual studio output.

also, I’m using v20.12.00 because v20.12.01 was throwing a syntax error 🙁

the first line of the error:
Parvin, [27.03.21 20:05]

is extra 🙂

Hi kasra,

check out this doc page: https://docs.microsoft.com/fr-fr/windows/win32/fileio/maximum-file-path-limitation

Does it solve your problem?

Meanwhile, can you describe the context of the issue? Does it happen when you try to install Sofa or compile it? Can you check that the runSofa.exe binary is created despite your errors?

Thank you

Thank you for your kind response,

I have checked that link(I have set that reg and rebooted), but it wasn’t helpful 🙁

I’m trying to compile the source code using this
> I cant use precompiled binaries because I need to use SofaPython3.

Also, there was no runSofa.exe file.

Thank you for your help. It’s about two weeks, walking on my nerves 🙂

Hello, I got the same error few months ago:

and I set up an issue for a short explanation: Issue1716

The registry thing did solve the issue on my setup. (Win10 20H2)

If it really does not help, a commit has been implemented starting from v20.12.01 to shorten paths.
Could you tell us what is your syntax error when you try to compile v20.12.01 ?
