# Build DUNE-DAQ release for CentOS Stream 8.

###### tags: `DAQ` `protoDUNE` `DUNE` `Software Management`

## Current UPS products for CentOS 7

## Build external products

* Use `np04-srv-019` to build the external products and the DAQ release.

[pding@np04-srv-019 ~]$ cat /etc/redhat-release
CentOS Stream release 8

* Set up local build area for UPS products

mkdir -p /scratch/dunedaq_cs8

# set up http proxy for public internet access
source ~np04daq/bin/web_proxy.sh

# clone daq-release repo 
git clone https://github.com/DUNE-DAQ/daq-release

# create new UPS products area
./daq-release/scripts/create-ups-products-area.sh -t /scratch/dunedaq_cs8/products

source /scratch/dunedaq_cs8/products/setup

* Build `gcc v8.2.0`, `boost v1.73.0` and various versions of `cmake` for CS8

cd /scratch/dunedaq_cs8/products
curl https://scisoft.fnal.gov/scisoft/packages/gcc/v8_2_0/gcc-8.2.0-source.tar.bz2|tar xj

cd gcc/v8_2_0
./build_gcc.sh /scratch/dunedaq_cs8/products tar

* Build `cmake v3_10_1`, this is used by `cetpkgsupport`

* Obtain `catch`, `cetpkgsupport` and `cetbuildtools` from [SciSoft](https://scisoft.fnal.gov/scisoft/packages/).

* Build `cppunit v1_15_1a` and `tbb v2020_2a`.

* Build `sqlite v3_32_03_00`

* Build `hep_concurrency`, `cetlib_except` and `cetlib` for CS8
These three packages have their repositories hosted on `cdcvs.fnal.gov`, which are only accessible from onsite@Fermilab. Cloning those on a DUNE GPVM node with:

for i in hep_concurrency cetlib cetlib_except; \ 
do \
git clone http://cdcvs.fnal.gov/projects/$i; \
done

Then check out the versions used by the latest DUNE DAQ release (refer to the `release_manifest.sh` in `daq-release` for the latest frozen release.)

* Build `hdf5 v1_12_0a`, `gdb` and `clang`.

* Build `ninja`, `python`
Install `libffi-dev`, `libnsl2-devel`, `libtirpc-devel`, `openssl-devel`, `gdbm_devel` before building `python`, otherwise it will end with error building `_ctypes`, `_gdbm`, `_dbm`, and `_nis` module.

* Build `highfive`, `pistache`, `nlohmann_json`, `cpr` (with `ssibuildshimlibs`)
`cpr` build script has an error (`mkdir -l` instead of `mkdir -p`)

* Build ` double_conversion fmt glog googletest libevent folly zmq cppzmq msgpack_c pybind11 pugixml librdkafka yaml_cpp` using `cetbuildtools`

* Tripped over pistache... It does not have a tag, instead we were using the commit dated on 2020-10-07

* Build `protobuf` and new version of `highfive`; building `protobuf` requires system packages for `libtool` `autoconf` and `automake`.

## Build `dunedaq-v2.8.0` and `dunedaq-develop` release

* Had to install `ztsd`, `libzstd-devel`
