Lots of build problems

[mattahorton]

Hey there, Chris.

I tried to build this, but ran into issues about it not being able to link Hapitrip.

Then I tried to shake up my qt environment and my local environment is now so hosed I can't even recreate the errors.

I know you hadn't intended to share this yet, but the instructions for building guiDemo weren't totally clear.

Reread this, and it's not totally helpful.

I think the place to start is that there were errors with the build finding Hapitrip's symbols. Almost like it was included improperly or not at all.

Am I supposed to cd guiDemo before the instructions in BUILD.TXT? Because I did.

hey @cchafe after our chat, I fixed my local issues. Running make twice didn't work :/

I'm pretty sure the build instructions only work on Linux/Ubuntu.

I think I'm able to get a build going through Docker but I have no way of testing it, I just see that the build succeeded. I did have to build each of the individual projects (guiDemo/libregulator, guiDemo/librtaudio, and guiDemo/libhapitrip) before doing the guiDemo build itself.

My Dockerfile:

FROM ubuntu:20.04

ENV DEBIAN_FRONTEND=noninteractive

RUN apt-get update \
    && apt-get install --no-install-recommends -y qt5-default qt5-qmake qttools5-dev git ca-certificates make cmake \
                                                  build-essential pkg-config libjack-jackd2-dev libasound-dev libpulse-dev

RUN echo "Building hacktrip" \
    && cd /root/ \
    && git clone --recurse-submodules https://github.com/cchafe/hacktrip.git \
    && cd hacktrip \
    && export GIT_SHA=`git rev-parse --short=12 HEAD` \
    && export ARCH=`dpkg --print-architecture` \
    && export LD_LIBRARY_PATH=/root/hacktrip/guiDemo/librtaudio:/root/hacktrip/guiDemo/libhapitrip \
    && echo $LD_LIBRARY_PATH \
    && ls -ltrah \
    && cd guiDemo \
    && echo "Building libregulator" \
    && cd libregulator \
    && qmake libregulator.pro \
    && make clean \
    && make \
    && cd .. \
    && echo "Building librtaudio" \
    && cd librtaudio \
    && qmake librtaudio.pro \
    && make clean \
    && make \
    && cd .. \
    && echo "Building libhapitrip" \
    && cd libhapitrip \
    && qmake libhapitrip.pro \
    && make clean \
    && make \
    && cd .. \
    && echo "Building guiDemo" \
    && qmake guiDemo.pro \
    && make clean \
    && make

Command to execute:

docker build --progress=plain -t hacktrip -f ./Dockerfile .
