Alpine Linux is a popular choice for building docker. Since v3.17, leveldb version is bumped from v1.22 to v1.23, where the new version disabled rtti, which caused many packages to break, including popular python module, plyvel. I encountered this problem when building electrumX docker image. Googling around I realize this is a popular problem and there are no easy and obvious solutions.
I decided to simply build apk files for leveldb v1.22 against the latest alpine linux, which is 3.20 today.
Steps:
- Mostly follow an excellent tutorial at fudex.org on setting up the docker build environment.
- Check out aports at alpine version v3.16, (host) git clone –depth=1 https://gitlab.alpinelinux.org/alpine/aports -b 3.16-stable aports-3.16
- Copy over leveldb APKBUILD file over to the latest 3.20 aports, (host) cp -a aports-3.16/main/leveldb aports/main/
- go back to alpine-dev container and build the package files
- (alpine-dev) cd ~/aports/main/leveldb
- (alpine-dev) abuild -r
The file APK files are located under ~/packages/main/x86_64. For convenience, I have include those two files below. Of course, you should strip the “.bin” suffix before using them. I had to add the suffix to work around wordpress restrictions. Please refer to this docker file to see how these files are used in a real case.
