I created a project with the command: anchor init solanasc and I receive this error when I run anchor build ERROR cargo_build_sbf] Failed to obtain package metadata: `cargo metadata` exited with an error: error: failed to load manifest for workspace member `\\?\C:\Users\user\Desktop\Projects\Rust_projects\solanasc\programs\*` Caused by: failed to read `\\?\C:\Users\user\Desktop\Projects\Rust_projects\solanasc\programs\*\Cargo.toml` Caused by: The filename, directory name, or volume label syntax is incorrect. (os error 123) I have tried the solutions here : `anchor build` fails with error, "failed to load manifest for workspace member" , to no avail. I am currently using Windows 10, and git bash. Here is my cargo.toml: [package] name = "solanasc" version = "0.1.0" description = "Created with Anchor" edition = "2021" [lib] crate-type = ["cdylib", "lib"] name = "solanasc" [features] no-entrypoint = [] no-idl = [] no-log-ix-name = [] cpi = ["no-entrypoint"] default = [] [dependencies] anchor-lang = "0.29.0"

I had the same problem, the error suggests that there is an invalid file path or character in the Cargo.toml file. I resolve it in changing: [workspace] members = [ "programs/*" ] [profile.release] overflow-checks = true to [workspace] members = [ "programs/my_program_name" ] [profile.release] overflow-checks = true t's not exactly the same configuration as your project, but if it helps.

Check your toml you might want [features] default = [] cpi = ["no-entrypoint"] no-entrypoint = [] no-idl = [] no-log-ix-name = [] idl-build = [ "anchor-lang/idl-build", "anchor-spl/idl-build", ] [dependencies] anchor-lang = {version = "0.31.0", features = ["init-if-needed"] } anchor-spl = { version = "0.31.0", features = ["metadata"] }
