No Apple Silicon bottles available: pdftk-java, pandoc

What you were trying to do (and why)

Trying to install formulae pdftk-java and pandoc.
Other formulae were installed without any problem.

What happened (include screenshots)

Error message "no bottle available!" appeared.

Log:

% brew install pdftk-java
Error: pdftk-java: no bottle available!
You can try to install from source with:
brew install --build-from-source pdftk-java

What you expected to happen

Proper installation.

Bottles seem to be available for macOS Big Sur (= macOS 11) for Intel only, not for Apple Silicon which I have:

• https://formulae.brew.sh/formula/pdftk-java
• https://formulae.brew.sh/formula/pandoc

For example, this formula provides bottle (binary package) installation support for Apple Silicon Big Sur and is installed without any problem:

• https://formulae.brew.sh/formula/rsync

If there is no bottle it means the software doesn't build on ARM.

I have reported this to the software packages:

• pandoc doesn't build for macOS Big Sur (= macOS 11) with the Apple M1 chip jgm/pandoc#7294
• https://gitlab.com/pdftk-java/pdftk/-/issues/92

As a workaround for pdftk, this package may work:

As a preliminary solution, I was successful in installing the Intel version of homebrew in /usr/local (in parallel to the M1 version in /opt/homebrew) using Apple's Rosetta 2 layer. The Intel packages (homebrew formulae) seem to work without any problem on the Apple M1 architecture. Both pdftk and pandoc work even without prefixing 'arch -x86_64' (e.g., the command 'pandoc sample.md -o sample.html' as in the example linked below).

Commands:

arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
alias ibrew='arch -x86_64 /usr/local/bin/brew'
ibrew analytics off
ibrew install pdftk-java
ibrew install pandoc
