            Bug ID: 27756
           Summary: BZ_NO_STDIO causes ERROR 1 bzip2.c:332:4: error:
                    unknown type name ‘BZFILE’
           Product: bzip2
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: bzip2

  Target Milestone: ---

Without touching anything bzip2 compiled and installed

Ubuntu 20.04 make 4.2.1 gcc 9.3.0

in the top of bzip2.c added #define BZ_NO_STDIO 1

kevin@Aorus:~/bzip2-1.0.8$ make

If compilation produces errors, or a large number of warnings,
please read README.COMPILATION.PROBLEMS -- you might be able to
adjust the flags in this Makefile to improve matters.

Also in README.COMPILATION.PROBLEMS are some hints that may help
if your build produces an executable which is unable to correctly
handle so-called 'large files' -- files of size 2GB or more.
