I am trying to build Canon printer driver on my repo for this issue but stuck with missing header.
data_process.c:28:10: fatal error: libxml/parser.h: No such file or directory
#include <libxml/parser.h>
^~~~~~~~~~~~~~~~~
I found the missing header in libxml2.dev (using nix-build '<nixpkgs>' -A libxml2.dev and inspect the result-dev directory)
but when I try to use it in the expression capt.nix at line #62 it failed with
/nix/store/7r0yjzdjc2lymjszcxcv220z7hkvzw70-stdenv-linux/setup: line 1338: -I/nix/store/im853gaq498i1pha0lhvzjlylh2sjbwq-libxml2-2.9.9-dev/include/libxml2: No such file or directory
