Python 3.13 support: Missing pre-built wheels for Linux ARM64

[drater05]

Summary

Python 3.13 has no pre-built wheels, and user dictionary compilation fails even with system MeCab.

Environment

• Python: 3.13.2
• Platform: Linux ARM64 (Docker)
• python-mecab-ko: 1.3.7

Issues

1. No Python 3.13 Wheels

RuntimeError: mecab-config not found

Latest release (July 2024) predates Python 3.13 (October 2024).

2. User Dictionary Compilation Fails

Even with apt-get install libmecab-dev, basic parsing works but dict-index fails:

dictionary.cpp(355) Context ID files may be broken

Comparison:

• Python 3.12 (wheel): ✅ Works perfectly
• Python 3.13 + apt mecab: ✅ Basic parsing, ❌ User dict
• Python 3.13 + source mecab-ko: ✅ Everything works

Workaround

Build MeCab-ko 0.996-ko-0.9.2 from source before installing python-mecab-ko:

FROM python:3.13-slim

RUN apt-get update && apt-get install -y build-essential curl && rm -rf /var/lib/apt/lists/*

# Build MeCab-ko from source (same version as wheel build)
RUN cd /tmp && \
    curl -fsSL https://bitbucket.org/eunjeon/mecab-ko/downloads/mecab-0.996-ko-0.9.2.tar.gz | tar xz && \
    cd mecab-0.996-ko-0.9.2 && \
    # Update config for ARM64 support
    curl -fsSL "http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess;hb=HEAD" -o config.guess && \
    curl -fsSL "http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD" -o config.sub && \
    chmod +x config.* && \
    ./configure --enable-utf8-only && make -j$(nproc) && make install && ldconfig && \
    cd /tmp && rm -rf mecab*

RUN pip install python-mecab-ko python-mecab-ko-dic

Request

Please publish Python 3.13 wheels in the next release.

한국어 요약

문제:

1. Python 3.13용 wheel이 없어서 설치 실패
2. 시스템 MeCab으로는 기본 파싱은 되지만 사용자 사전 컴파일 실패

원인:

• 최신 릴리스(2024년 7월)가 Python 3.13 출시(2024년 10월) 이전
• 시스템 MeCab에 dictionary.cpp 버그 존재
• Python 3.12 wheel에는 수정된 버전 포함

해결:

• MeCab-ko 0.996-ko-0.9.2를 소스에서 직접 빌드
• --enable-utf8-only 플래그 사용
• ARM64 지원을 위해 config.guess/config.sub 업데이트 필요
