I've checked the code again, and found out two things:
1. The error message is mangled because it contains a CR character at
the end (harmless bug).
2. The only situation that, I think, leads to this error is a badly
formatted, badly interpreted or mangled "data" command. That is,
the number of bytes declared do not match the actual content bytes.
Both of which make me suspicious about an automatic line-ending
conversion going on (LF to CRLF most likely). What I don't really know
is who to blame.
Here are some more tests you can do to help the diagnosis:
- Does the error happen quickly or it takes a while to show up?
- Try the conversion WITHOUT a pipeline. That is:
git fast-export --all >my_export
fossil import --git blah.fossil my_export
Note the absence of redirection in the second command.
- Take a look at the "my_export" file with a text editor or a pager
looking for the same string ("${CFLAGS} -fPIC -shared -o $@"), then
scroll back until you find a line that starts with "data " followed
by a number.
Then, extract the content from the "data" line until the end of the
content (i.e. the whole contents of that particular version of your
Makefile) and calculate its size in bytes. If I'm correct the size
of the Makefile content should approximately match:
content_size = reported_size + linecount_in_content
Once this behaviour is confirmed, the next step is to look out for
guilty parties ;-)
