Cannot build apache image for latest version: COPY failed: stat usr/local/lib/php/extensions/no-debug-non-zts-20190902/pdlib.so: file does not exist

[E4est]

When I am trying to build the Dockerfile, I get COPY failed: stat usr/local/lib/php/extensions/no-debug-non-zts-20190902/pdlib.so: file does not exist

Looking further into the output, it looks like in STEP 7 another Zend Module Api Version is used than expected.

Step 7/29 : RUN cd;     wget -c -q https://github.com/matiasdelellis/pdlib/archive/$PDLIB_BRANCH.zip     && unzip $PDLIB_BRANCH     && mv pdlib-* pdlib     && cd pdlib     && phpize     && ./configure     && make     && make install

Changing line 58 COPY --from=builder /usr/local/lib/php/extensions/no-debug-non-zts-20190902/pdlib.so /usr/local/lib/php/extensions/no-debug-non-zts-20190902/ to COPY --from=builder /usr/local/lib/php/extensions/no-debug-non-zts-20200930/pdlib.so /usr/local/lib/php/extensions/no-debug-non-zts-20200930/ seems to resolve the issue for now.

The only problem I see is that it might break again in the future. Any ideas on how to permanently fix this for future versions?

Hi, please pull the files again. I've fixed it for the moment. I will work on a solution so that it is dynamic. Regards, Klaus

A dynamic configuration of the path seems to be tricky. Docker seems not to allow that because it could be security problem. Anybody who has an idea?

[guystreeter]

There might be a better way (I'm not that great with sed), but

php -i | grep ^extension_dir | sed -E 's/^[^ ]* => [^ ]* => (.*)$/\1/'

will give you the full directory path.

Closed, I will have to update the build file every time Dlib gets updated. By design dynamic paths are not allowed (docker security rule).
