Please provide instruction on how to compile compatible packages about aggregate HOT 9 CLOSED

It's a lot simpler here. Just use conda-build 3. Since the compiler packages that it uses are all self-contained with their own sysroots, it's just a matter of letting the compiler packages work their magic.

The only real trick to this is that you should issue build commands from the root of the aggregate folder, where conda_build_config.yaml lives, or manually specify an alternate conda_build_config.yaml file that conda-build should use. That's the -m flag to conda-build.

we'll try to write up some docs soon, too.

This is not working for me. For example take this recipe:

{% set version = "1.0.0.1832.f7e6fca" %}

package:
  name: libblitz
  version: {{ version }}

source:
  git_url: https://github.com/wperkins/blitz.git
  git_rev: f7e6fca9ad683db7c0a41c250db346ccae6732c3

build:
  number: 0
  run_exports:
    - {{ pin_subpackage('libblitz') }}

requirements:
  build:
    - python 2
    - autoconf
    - automake
    - libtool
    - {{ compiler('c') }}
    - {{ compiler('cxx') }}

test:
  commands:
    - test -d $PREFIX/include/blitz        # [unix]
    - test -e $PREFIX/lib/libblitz.a       # [unix]
    - test -e $PREFIX/lib/libblitz.so      # [linux]
    - test -e $PREFIX/lib/libblitz.dylib   # [osx]

with this build.sh:

#!/bin/bash

if [[ $ARCH == 64 ]];
then
	export ARCH_CMD="--enable-64bit"
else
	export ARCH_CMD="--enable-simd-width=8"
fi

autoreconf -vif

./configure \
  --prefix="${PREFIX}" \
  --enable-static \
  --enable-shared \
  --enable-optimize \
  --enable-threadsafe \
  --enable-serialization \
  ${ARCH_CMD} \
  CPPFLAGS="-I${PREFIX}/include -pthread" \
  CFLAGS="-I${PREFIX}/include -pthread -DBZHAVE_STD" \
  CXXFLAGS="-I${PREFIX}/include -pthread -DBZHAVE_STD" \
  LDFLAGS="-L${PREFIX}/lib"
make
make check
make install

This recipe compiles fine on the conda-concourse-ci docker image but on my laptop which has Arch Linux it fails with the following error:

Here is the full log.

Without looking at source (on my phone on a bus), that appears to come from a preprocessor definition that is getting triggered differently in either build environment. You may need to change the preprocessor condition to be compiler-specific rather than platform-specific?

from aggregate.

I think this error is related to boost. I did not know blitz needs boost for compilation! In my log I see a warning like configure: WARNING: BOOST_CPPFLAGS -I/usr/include which seems to be the problem. Unfortunately a new boost package with the new C++ ABI is not released yet so I cannot fully test this with the new compilers.

from aggregate.

sorry about that. We'll try to build out more packages very soon.

from aggregate.

@183amir, boost packages with the new C++ ABI are released now. Please close if everything is OK.

Hi @mingwandroid I will test this again and report back. It would best however to update the readme to mention that conda build 3 needs to be used.

from aggregate.

I don't think that's necessary. Using the latest features in recipes is always going to require the latest conda-build and updating conda-build is always a good idea anyway.

from aggregate.

The recipe of libblitz (posted above) fails for me on both archlinux and the continuumio/conda-concourse-ci docker image now with boost 1.65.1 from the main channel. But I am not getting the old error anymore which means something got fixed at least using the new boost.
Since the blitz++ issue may not be related to the issue here, I will close this issue.
Here is the build log and the configure script if you are interested.

Thank you for your work on conda-build-3 and the compiler packages.
