Hello Brian,

it seems like the header linux/ext2_fs.h is missing on your build system:

fdmount.c:25:10: fatal error: linux/ext2_fs.h: No such file or directory

You can check if it is there with:

ls -l /usr/include/linux/ext2_fs.h

If it isn't, installing this package should solve the problem:

sudo apt-get install e2fslibs-dev

It might be necessary to re-run ./configure afterwards, if it depends on the existence of this package.

Hello, all:

??? I went to put together my first run of fdutils. I entered
"./configure", all went well. Using "make" went through several stages,
then bombed out with a fatal error message, posted at the end of this
message.

??? I am using an Ubuntu Studio 18.04 host system, all is up to date
with it. I followed the trail, installing (via apt-get) bison, flex, and
fdutils. I am not certain how to get a version level on "mtools".

??? At this point, there is only a broken make sequence, and it will go
no further until I find out what is causing it. Header files not
included? Environment variables not set? I am not certain.

??? The message:

fdmount.c:25:10: fatal error: linux/ext2_fs.h: No such file or directory
?#include <linux/ext2_fs.h>

=========================

(additional efforts to track down internal functions, e.g., fdmount, and
compile separately resulted in):

Ideas, anyone?
