Missing `assert_isa` symbol #9

Closed rjbell4 closed 3 years ago

rjbell4 commented 3 years ago

When I try to compile and run in an Alpine Linux Docker image, I get the following error:

Can't load '/usr/src/app/local/lib/perl5/x86_64-linux-thread-multi/auto/JSON/JQ/JQ.so' for module JSON::JQ: Error relocating /usr/src/app/local/lib/perl5/x86_64-linux-thread-multi/auto/JSON/JQ/JQ.so: assert_isa: symbol not found at /usr/share/perl5/core_perl/XSLoader.pm line 93.
 at /usr/src/app/local/lib/perl5/x86_64-linux-thread-multi/JSON/JQ.pm line 23.
Compilation failed in require.
BEGIN failed--compilation aborted.

I've searched, but I cannot find where assert_isa should be defined. It's not in libperl.so:

# LD_PRELOAD=/usr/lib/perl5/core_perl/CORE/libperl.so ldd /usr/src/app/local/lib/perl5/x86_64-linux-thread-multi/auto/JSON/JQ/JQ.so
        /lib/ld-musl-x86_64.so.1 (0x7fe36870b000)

Error relocating /usr/src/app/local/lib/perl5/x86_64-linux-thread-multi/auto/JSON/JQ/JQ.so: assert_isa: symbol not found

And some Googling hasn't been helpful. I'm hoping you will be!

Hi, it is defined within the code https://github.com/dxma/perl5-json-jq/blob/master/lib/JSON/JQ.xs#L191 Kind of strange it compiled but raised this runtime error. Could you recompile it and show me the full output ?

rjbell4 commented 3 years ago

My exact environment is a little more complicated, so to try to make in simpler for you to reproduce, I boiled it down to this Dockerfile (so far), which reproduces the issue:

FROM alpine:3.13
RUN apk add bash wget unzip perl perl-dev perl-app-cpanminus build-base cmake openssl openssl-dev zlib-dev
RUN env PERL_MM_USE_DEFAULT=1 cpanm Carton
RUN cd /root && echo "requires 'JSON::JQ';" > cpanfile && carton install
RUN perl -I/root/local/lib/perl5 -MJSON::JQ -le 'print "It works"'

This isn't exactly my setup, but if you could see what's wrong with the above Dockerfile (put into an empty directory, run docker build ., look for an It works output, etc.), then I would be grateful, and would take it from there.

rjbell4 commented 3 years ago

FYI, I also tried using cpanm, rather than carton. Here's the build log in that case: https://gist.github.com/c7b2e6ddc58c933649af63ad5db6f54e

The output to screen ended as follow:

I looked at the code. I noticed that assert_isa() is declared as inline, but not static, like all the other functions around it. I have verified that if I add static (either in place of inline or in addition to it), then JQ.so loads successfully.
