-====== crossbuild-essential-armhf ======
-----
-`crossbuild-essential-armhf` is essentially a **convenience/meta-package that installs the appropriate cross-compilation components**.
-===== What is installed =====
-On Debian Bookworm, `crossbuild-essential-armhf` version 12.9 declares only these direct dependencies:
-<code>
-gcc-arm-linux-gnueabihf
-g++-arm-linux-gnueabihf
-dpkg-cross
-</code>
-The meta-package itself is tiny. Those direct dependencies pull in the actual compiler, linker, target C library, headers and C++ runtime. The significant transitive packages on a clean Bookworm installation include:
-<code>
-gcc-12-arm-linux-gnueabihf
-g++-12-arm-linux-gnueabihf
-cpp-arm-linux-gnueabihf
-cpp-12-arm-linux-gnueabihf
-binutils-arm-linux-gnueabihf
-libc6-armhf-cross
-libc6-dev-armhf-cross
-linux-libc-dev-armhf-cross
-libgcc-s1-armhf-cross
-libgcc-12-dev-armhf-cross
-libstdc++6-armhf-cross
-libstdc++-12-dev-armhf-cross
-libasan8-armhf-cross
-libatomic1-armhf-cross
-libgomp1-armhf-cross
-libubsan1-armhf-cross
-</code>
-`dpkg-cross` also brings in Debian packaging support, including `dpkg-dev`, Perl modules and `libdebian-dpkgcross-perl`. The exact complete transaction depends on which packages are already installed.
-Importantly, `crossbuild-essential-armhf` does **not** install arbitrary target development libraries such as:
-<code>
-libssl-dev:armhf
-libcurl4-openssl-dev:armhf
-libasound2-dev:armhf
-</code>
-Those must be installed separately through Debian multiarch or supplied by a target sysroot. Adding `armhf` as a foreign architecture is required for installing `:armhf` multiarch packages, but it is not required merely to install the cross-toolchain packages listed above.
-===== Check what would be installed =====
-To see exactly what APT would add on a particular Debian system without installing anything:
-<code>
-sudo apt update
-sudo apt install --simulate crossbuild-essential-armhf
-</code>
-To inspect the direct dependencies or recursively list dependencies:
-<code>
-apt-cache depends crossbuild-essential-armhf
-apt-cache depends \
-    --recurse \
-    --no-recommends \
-    --no-suggests \
-    crossbuild-essential-armhf
