Dear All,
I attempted to build the TexGen open-source code on an Ubuntu Linux machine. Before building the source code, I needed to install the following dependencies: CMake, SWIG, and VTK. While I successfully installed CMake and SWIG, I encountered issues while compiling VTK6.3.
/usr/include/c++/13/bits/stl_tree.h:772:15: error: static assertion failed: comparison object must be invocable as const 772 | is_invocable_v, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I believe this error is due to a compatibility issue with the C++ compiler version, which may not be compatible with VTK 6.30 for building its source code.
By default, my machine uses GCC 7.5.0 as the C++ compiler. To address the compatibility issues, I installed newer versions of GCC, specifically GCC 13.0 and 14.0. However, despite installing these updated C++ compilers, my machine continues to use the older GCC version (7.5.0) when building the VTK source code, which in turn affects both VTK6.3 and TexGen source build.
Could anyone advise on how to resolve this issue and ensure that my machine uses the updated GCC compiler for building VTK and TexGen? . Thanks in advance Pandi P
Peter Breuer : Thank you for the prompt response and may I know the way to move the gcc++ backwards from the Texgen source code. I had posted some my comments in the GitHUb but there is no response yet from Texgen developer.
Thanks
Peter Breuer : Thank you for the detailed response. My machine has the following version of the compiler:
- g++ (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0
- gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0
To compile the TexGen source code without any issues, I was advised by the TexGen developers to use VTK 6.3, which would be compatible. However, even with this version of VTK and the specified compiler versions on my machine, I still encounter the above error.
Also in the past, I was also tried to compile the VTK6.3 using g++ and gcc both with 7.0.5 version, but I encountered again the same problem.
Thanks Peter Breuer
Peter Breuer Now I get the following error:
