在Alpinelinux下编译PHP OCI8扩展

Question

我正在尝试编译PHP OCI8扩展并在Alpinelinux下运行它。但似乎扩展对musl libc中定义glibc但缺少的符号有一些依赖性。

我可以使用任何已编译的PHP OCI8扩展名吗？或者，是否有任何变通办法可以使oci8扩展和oracle Instant Client与alpinelinux一起使用。

提前致谢！

事实证明，我针对Alpine的解决方案很简单：使用Instant Client v11（11.2.0.4）代替v12（12.2.0.1）：

ENV LD_LIBRARY_PATH /usr/local/instantclient
ENV ORACLE_HOME /usr/local/instantclient

# Install Oracle Client and build OCI8 (Oracle Command Interface 8 - PHP extension)

RUN apk add php7-pear php7-dev gcc musl-dev libnsl libaio &&\
## Download and unarchive Instant Client v11
  curl -o /tmp/basic.zip https://raw.githubusercontent.com/bumpx/oracle-instantclient/master/instantclient-basic-linux.x64-11.2.0.4.0.zip && \
  curl -o /tmp/sdk.zip https://raw.githubusercontent.com/bumpx/oracle-instantclient/master/instantclient-sdk-linux.x64-11.2.0.4.0.zip && \
  curl -o /tmp/sqlplus.zip https://raw.githubusercontent.com/bumpx/oracle-instantclient/master/instantclient-sqlplus-linux.x64-11.2.0.4.0.zip && \
  unzip -d /usr/local/ /tmp/basic.zip && \
  unzip -d /usr/local/ /tmp/sdk.zip && \
  unzip -d /usr/local/ /tmp/sqlplus.zip && \
## Links are required for older SDKs
  ln -s /usr/local/instantclient_11_2 ${ORACLE_HOME} && \
  ln -s ${ORACLE_HOME}/libclntsh.so.* ${ORACLE_HOME}/libclntsh.so && \
  ln -s ${ORACLE_HOME}/libocci.so.* ${ORACLE_HOME}/libocci.so && \
  ln -s ${ORACLE_HOME}/lib* /usr/lib && \
  ln -s ${ORACLE_HOME}/sqlplus /usr/bin/sqlplus &&\
  ln -s /usr/lib/libnsl.so.2.0.0  /usr/lib/libnsl.so.1 &&\
## Build OCI8 with PECL
  echo "instantclient,${ORACLE_HOME}" | pecl install oci8 &&\
  echo 'extension=oci8.so' > /etc/php7/conf.d/30-oci8.ini &&\
#  Clean up
  apk del php7-pear php7-dev gcc musl-dev &&\
  rm -rf /tmp/*.zip /var/cache/apk/* /tmp/pear/
