I am trying to build the watchman from source and it is successful with below files.

However, whenever I try to build a deb package, it fails on the below step during the /lib directory deletion.

# This is an implicit assertion that the `lib` directory is empty.
# We statically link dependencies for packaging purposes.
rmdir "$BUILT/lib"

As per the comments, it is expected to not have any files inside the lib/ directory but the ./autogen.sh command is generating three lib files as mentioned above. I am not very good at building the packages and want to understand what will fix this. FYI, I tried sudo apt-get install libgoogle-glog-dev libunwind-dev liblzma-dev and it didn't help.

Instead of rmdir "$BUILT/lib", adding these below lines helped to fix the build and create a deb file successfully.

cp "$BUILT/lib/libglog.so.0" "$PREFIX/lib/"
cp "$BUILT/lib/liblzma.so.5" "$PREFIX/lib/"
cp "$BUILT/lib/libunwind.so.8" "$PREFIX/lib/"
