I want to do some work with 4K blocksize devices (real and virtual).
I found
examples/create_disk.c
then found it didn't contain the blocksize option. I have Ubuntu 20.04
guestfish version 1.40.2. I investigated and found a recent checkin 1.45.2 that
adds this option.
Do you mean this one?

lib: add support for disks with 4096 bytes sector size
I then rebuilt libguestfs from scratch using tag V1.45.2.
I noted the warning not to "make install" it and stopped.
I don't see how to build create_disk.c against a libguesfs.a version 1.45.2.
The faq/etc talk about running a self-compiled program using ./run but not how
to make such a program with a different version.
You can just do something like:
gcc create_disk.c -L lib/.libs -lguestfs -o create_disk
./run ./create_disk
