output of clang --version

Ubuntu clang version 14.0.0-1ubuntu1
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin

I noticed that /usr/lib/libstdc .so was missing, so manually created a symlink sudo ln -s /usr/lib/x86_64-linux-gnu/libstdc .so.6 /usr/lib/libstdc .so.

Then I ended up in this error on flutter run

CodePudding user response：

Turns out, upgrading to clang-14 caused the problem. This is how I fixed it:

• downgrade to clang-13
• create a symlink, if /usr/lib/libstdc .so doesnt exists. sudo ln -s /usr/lib/x86_64-linux-gnu/libstdc .so.6 /usr/lib/libstdc .so
• if you are getting fatal error: 'type_traits' file not found on flutter run, export clang include path export CPLUS_INCLUDE_PATH="${CPLUS_INCLUDE_PATH: ${CPLUS_INCLUDE_PATH}:}/usr/lib/llvm-13/include/c /v1/"
