user5610: I am in a nix-shell and attempting to build the code for week 1. After lots of promising output, it fails with this error.

Failed to build lzma-0.0.0.3. The failure occurred during the configure step.
Build log (
/Users/jwb/.cabal/logs/ghc-8.10.2.20201118/lzm-0.0.0.3-09eda932.log ):
Configuring library for lzma-0.0.0.3..
cabal: Missing dependency on a foreign library:
* Missing (or bad) header file: lzma.h
* Missing (or bad) C library: lzma
This problem can usually be solved by installing the system package that
provides this library (you may need the "-dev" version). If the library is
already installed but in a non-standard location then you can use the flags
--extra-include-dirs= and --extra-lib-dirs= to specify where it is.If the
library file does exist, it may contain errors that are caught by the C
compiler at the preprocessing stage. In this case you can re-run configure
with the verbosity flag -v3 to see the error messages.
If the header file does exist, it may contain errors that are caught by the C
compiler at the preprocessing stage. In this case you can re-run configure
with the verbosity flag -v3 to see the error messages.
cabal: Failed to build lzma-0.0.0.3 (which is required by
plutus-pioneer-program-week01-0.1.0.0). See the build log above for details.


I did cabal update beforehand, both outside and inside nix-shell. Any suggestions?

user5926: You probably need to install the development package:
apt install liblzma-dev
