[jira] [Created] (SINGA-432) Update depdent lib versions in
conda-build config
wangwei created SINGA-432:
-----------------------------
Summary: Update depdent lib versions in conda-build config
Key: SINGA-432
URL: https://issues.apache.org/jira/browse/SINGA-432
Project: Singa
Issue Type: Improvement
Reporter: wangwei
We have been using gcc 4.8.5 to Singa.
The latest gcc is 8.2. Many dependent libs (e.g., protobuf) are built with newer versions of gcc which has a different ABI as 4.8.5.
This ticket is going to update these libs and gcc using [conda-build 3.0|[https://www.anaconda.com/package-better-conda-build-3/].]
# introduce the build, host and run sections in meta.yaml
# introduce the conda_build_config.yaml to configure the lib versions. note the gcc version [must be 5.4|https://docs.conda.io/projects/conda-build/en/latest/resources/variants.html] as cuda does not support gcc>=6.
# use the compiler selected by conda via c_complier() cxx_compiler()
# use the cudnn from anaconda.
# move docker for conda build into tool/conda. Now the dockerfile for conda build and the dockerfile for devel are different. The former one uses the libs from anaconda. The later one uses the latest libs from ubuntu.
