This section lists categories of code changes necessary to build Slicer with VTK 9.0. Each category has a short description, an example error message, a suggested upgrade path, and references to relevant commits.
Add missing std::
To fix warning message similar to:
/usr/include/c++/5/iosfwd:162:34: note: ‘std::ifstream’ /tmp/SPHARM-PDM/Modules/CLI/MetaMeshTools/MeshMath.cxx:4082:5: error: ‘ofstream’ was not declared in this scope ofstream output; ^
/usr/include/c++/5/iosfwd:162:34: note: ‘std::ifstream’ /tmp/SPHARM-PDM/Modules/CLI/MetaMeshTools/MeshMath.cxx:4117:5: error: ‘ofstream’ was not declared in this scope ofstream output; ^
Replace code like this:
ifstream input; ofstream output;
By this:
std::ifstream input; std::ofstream output;
