    This issue might be a duplicate of existing issues. Please check:

    These issues also report similar GLIBC version compatibility errors on older Linux systems. The root cause appears to be that OpenCode (or its dependencies like bun-pty) is compiled against a newer version of GLIBC than what's available on your system.

    Feel free to ignore if your specific case involves the PTY library loading within the web interface, which may be a distinct issue.

    This is a GLIBC version mismatch in bun-pty. The library was built on Ubuntu 24.04 (GLIBC 2.39) but the system has an older version.

    Fix PR: sursaone/bun-pty#23

    This switches the build to ubuntu-20.04 (GLIBC 2.31) for broader compatibility.

    issue still exists, for desktop app as well

    probably related to opencode official docker image being an alpine image:
    __tls_get_addr: symbol not found
    getauxval: symbol not found
    gnu_get_libc_version: symbol not found

    We temporarily resolved the problem using the following steps:

    1. Install the glibc compatibility layer: Use sgerrand/alpine-pkg-glibc to import the glibc library files into Alpine.
    2. Force download of the glibc binary: Manually download opencode-linux-x64.tar.gz (the glibc compiled version) from GitHub Releases instead of using the official installation script (which will automatically detect and install the musl version).
    FROM ghcr.io/anomalyco/opencode:1.2.15

USER root

ENV GLIBC_RELEASE_VERSION=2.35-r1
ENV BUN_VERSION=1.3.9

RUN apk del libc6-compat gcompat || true \
    && apk add --no-cache curl libstdc++ unzip bash \
    && curl -L https://alpine-pkgs.sgerrand.com/sgerrand.rsa.pub -o /etc/apk/keys/sgerrand.rsa.pub \
    && curl -L https://github.com/sgerrand/alpine-pkg-glibc/releases/download/${GLIBC_RELEASE_VERSION}/glibc-${GLIBC_RELEASE_VERSION}.apk -o glibc.apk \
    && apk add --no-cache --force-overwrite glibc.apk \
    && rm glibc.apk

RUN curl -fsSL https://github.com/anomalyco/opencode/releases/download/v1.2.15/opencode-linux-x64.tar.gz -o opencode.tar.gz \
    && tar -xzf opencode.tar.gz -C /usr/local/bin \
    && rm opencode.tar.gz \
    && chmod +x /usr/local/bin/opencode \
    # Ensure glibc loader is in the standard path
    && mkdir -p /lib64 \
    && ln -sf /usr/glibc-compat/lib/ld-linux-x86-64.so.2 /lib64/ld-linux-x86-64.so.2

ENV LD_LIBRARY_PATH=/usr/glibc-compat/lib

    Hopefully this method can help others!
