# problem
problem: the quote crate produces a 'can't find crate for `proc_macro2`' problem

# solution

the solution for the problem is to add the -L to the --crate-name quote crate:

[nixos@nixos:~/rphtml/test/quote-1.0.39]$ /nix/store/9bc93rjal0wmb7cc5j0c94k5dfl2axiz-rustc-wrapper-1.86.0/bin/rustc --crate-name quote --edition=2018 src/lib.rs --crate-type lib --emit=dep-info,metadata,link
-C embed-bitcode=no --cfg 'feature="default"' --cfg 'feature="proc-macro"' --check-cfg 'cfg(docsrs,test)' --check-cfg 'cfg(feature, values("default", "proc-macro"))' --cfg no_literal_byte_character --cfg no_li
teral_c_string -C metadata=9b8a9fdb179dc4b4 -C extra-filename=-6aacf6b034557052 --extern proc_macro2=../deps/libproc_macro2/libproc_macro2-a253d4ccb9225c80.rmeta -L ../deps/libunicode_ident/ --out-dir ../deps/
 --cap-lints allow
 
so in nix terms this probably needs `propagatedBuildInputs`
