When building examples, the linker fails with multiple definition of entrypoint error because both spl-token and spl-token-2022 define the entrypoint() function by default.
Error:
error: ld returned 1 exit status
multiple definition of 'entrypoint'
spl_token-*.rlib: previous definition here
This SDK is an off-chain client library, not an on-chain program deployed to validators. The entrypoint() function is only needed for on-chain Solana programs. Client libraries only need the types and structs for parsing account data.
Fix: Add no-entrypoint feature to exclude the entrypoint symbol from compilation.
Before:
spl-token = "9.0.0"
spl-token-2022 = "10.0.0"
After:
spl-token = { version = "9.0.0", default-features = false, features = ["no-entrypoint"] }
spl-token-2022 = { version = "10.0.0", default-features = false, features = ["no-entrypoint"] }
