FUSE support not detected during ./configure

[varbytes]

Hi, I am trying to build libewf-experimental-20240506 on Ubuntu 18.04 LTS. Installing ewf-tools package won't work as that package does not have support for large disks (8TB image).

I've install autoconf, automake, autopoint, fuse, libfuse-dev, and libfuse2. However when I run ./configure, it still shows FUSE support: no.

Both make and make install runs without error but ewfmount gives error No sub system to mount EWF format.

How can I get the configure and make scripts to detect and include fuse support?

Thank you.

Thanks Joachim. I was able to look into the config.log and noted the following errors relating to fuse:

configure:75607: checking whether to use search for libfuse in includedir and libdir or in the specified DIR, or no if not to use libfuse

I tried fuse_CFLAGS='-D_FILE_OFFSET_BITS=64' ./configure but that didn't seem to work.

Adding -D_FILE_OFFSET_BITS=64 directly to line 75807 of configure finally made it work: CPPFLAGS="$backup_CPPFLAGS -DFUSE_USE_VERSION=30 -D_FILE_OFFSET_BITS=64"

Not sure if I'm doing something wrong with the fuse_CFLAGS variable but you can close this ticket. Let me know if you need information for troubleshooting.

Thank you for maintaining the project!

if you can attach or send me the config log by mail that could be useful, I suspect that the configure script is not fully able to find the fuse configuration. This changes from time to time

Attached config log from executing default configure script. Thank you!

Made some changes for fuse in the most recent commit but might need some more tweaking
