Alpine linux build fails

[olimsaidov]

How can I build this repo in docker official alpine based postgres image. I am getting compile error:

gcc -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Wendif-labels -Wmissing-format-attribute -Wformat-security -fno-strict-aliasing -fwrapv -fexcess-precision=standard -O2 -fpic -I. -I./ -I/usr/local/include/postgresql/server -I/usr/local/include/postgresql/internal -D_GNU_SOURCE -I/usr/include/libxml2   -c -o src/librabbitmq/amqp_socket.o src/librabbitmq/amqp_socket.c

Hey,
This works for me.
Added include to types.h:

FROM postgres:12-alpine as builder

RUN apk update && apk add git make gcc linux-headers libc-dev libxml2-dev alpine-sdk musl-dev
RUN git clone https://github.com/omniti-labs/pg_amqp.git workdir

ARG AMQP_H=src/librabbitmq/amqp.h

RUN cd workdir \
        && head -n 2 ${AMQP_H} > ${AMQP_H}.temp \
        && echo "#include <sys/types.h>" >>  ${AMQP_H}.temp \
        && cat ${AMQP_H} | sed -e '1,3d' >> ${AMQP_H}.temp \
        && mv ${AMQP_H}.temp ${AMQP_H}

RUN cd workdir && make && make install


FROM postgres:12-alpine
COPY --from=builder /usr/local/lib/postgresql/pg_amqp.so /usr/local/lib/postgresql/pg_amqp.so
COPY --from=builder /usr/local/share/postgresql/extension /usr/local/share/postgresql/extension
COPY --from=builder /usr/local/share/doc/postgresql/extension /usr/local/share/doc/postgresql/extension
RUN chmod 755 /usr/local/lib/postgresql/pg_amqp.so \
        && chmod 644 /usr/local/share/postgresql/extension/amqp.control \
        && chmod 644 /usr/local/share/postgresql/extension/amqp--0.3.0--0.4.0.sql \
        && chmod 644 /usr/local/share/postgresql/extension/amqp--0.4.0--0.4.1.sql \
        && chmod 644 /usr/local/share/postgresql/extension/amqp--0.4.2.sql \
        && chmod 777 /usr/local/share/postgresql/extension/

I know that 777 is not recommended but it was for my local testing.
