How can I build pdfium on arm64 platform?(Debian glibc 2.28)

[MyChuan]

step 1, I'm run the sh by command "./build.sh -b chromium/5670 linux arm64". step 2, the error is "E: 软件包 libc6-i386 没有可安装候选 E: 无法定位软件包 gcc-9-multilib E: 无法定位软件包 g++-9-aarch64-linux-gnu E: 无法按照正则表达式 g++-9-aarch64-linux-gnu 找到任何软件包 E: 软件包 gcc-9-aarch64-linux-gnu:i386 没有可安装候选", then i comment it out. step 3, the error is "fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree." when it reaches gclient sync -r origin/chromium/5670 --no-history --shallow, but i can get the codes from gclient, then i copy it in this place. step 4, the error is "gn gen /root/zbc/projects/pdfium-binaries/pdfium-binaries/pdfium/out Traceback (most recent call last): File "/root/zbc/projects/pdfium-binaries/pdfium-binaries/depot_tools/gn.py", line 14, in import gclient_paths File "/root/zbc/projects/pdfium-binaries/pdfium-binaries/depot_tools/gclient_paths.py", line 24, in def FindGclientRoot(from_dir, filename='.gclient'): File "/usr/lib/python3.7/functools.py", line 477, in lru_cache raise TypeError('Expected maxsize to be an integer or None') TypeError: Expected maxsize to be an integer or None " How can i resolve the problems? Looking forward to your help.

Hi @MyChuan,

I had the same error today with the Windows build. I assumed it was because the Python version was too old, so I updated the runner. Guess what? It worked!

Try to upgrade to Python >= 3.9

Hi @MyChuan,

I don't know. The build works on Ubuntu, and it's all that matters to me. As I said in #90:

The goal of the project is to provide PDFium binaries, nothing more. The build scripts in this repository are just a side-product of this process. Those scripts only need to run on GitHub-hosted runners, and I have no intention of making them portable.

To build PDFium on unsupported Linux distributions, please follow the official instructions.

Thank you for your understanding.

Best regards, Benoit
