Error during the build when using php:fpm-alpine as the base image

[EvgenyOrekhov]

If I replace FROM alpine:latest with FROM php:fpm-alpine in alpine/Dockerfile, I get the following error during the build:

DYNLINK   libluajit.so
/usr/lib/gcc/x86_64-alpine-linux-musl/5.3.0/../../../../x86_64-alpine-linux-musl/bin/ld: lj_err_dyn.o: relocation R_X86_64_TPOFF32 against `static_uex' can not be used when making a shared object; recompile with -fPIC

ERROR: failed to run command: make -j1 TARGET_STRIP=@: CCDEBUG=-g XCFLAGS='-DLUAJIT_ENABLE_LUA52COMPAT' CC=cc PREFIX=/usr/local/openresty/luajit

Could you help me figure out how to fix it, please?

P. S. I understand that this issue should not be in this repo, because there is nothing wrong with your Dockerfile, I just wanted to get help from the experts.

It looks like php:fpm-alpine is using ENV instead of ARG in their Dockerfile. Thus they are polluting CFLAGS, CPPFLAGS, and LDFLAGS. The openresty build is picking those up and is not happy about it (notably wants fPIC instead of fPIE) . They should switch to ARG -- perhaps submit an issue with them.

You can modify the docker-openresty Dockerfile and put this right above the RUN command:

ENV CFLAGS ""
ENV CPPFLAGS ""
ENV LDFLAGS ""

I just tested it and it builds alpine.

@neomantra Thank you! You saved my day! I will submit an issue to the PHP guys.
