# SQLiteCpp Troubleshooting ## Common compiler errors - MSVC: `error C2065` or `C2039` usually means a missing include or wrong symbol. - GCC/Clang: `use of undeclared identifier` or `no member named` indicates missing includes or API mismatch. ## Common linker errors - `LNK2019 unresolved external symbol "SQLite::Database::exec"`: - Missing SQLiteCpp library or missing source file in build. ## Missing sqlite3 on Linux - Errors like `undefined reference to sqlite3_xxx`: - Install `libsqlite3-dev`, or enable internal sqlite3. - CMake option: `-DSQLITECPP_INTERNAL_SQLITE=ON`. ## Column metadata error - `undefined reference to sqlite3_column_origin_name`: - Your sqlite3 library lacks `SQLITE_ENABLE_COLUMN_METADATA`. - Options: - Rebuild sqlite3 with that flag. - Disable `SQLITE_ENABLE_COLUMN_METADATA`. - Use internal sqlite3 (`SQLITECPP_INTERNAL_SQLITE=ON`). ## Destructors and assertions - Do not throw in destructors; use `SQLITECPP_ASSERT()` instead.
