ADIOS2 2.10.2 Installation Failed: ZFP Issue

by Alex Johnson 45 views

Introduction

This article addresses a common installation problem encountered when trying to install ADIOS2 version 2.10.2 with ZFP compression using Spack, a package manager. Specifically, the issue arises due to CMake's inability to locate the ZFP package configuration files. This comprehensive guide will delve into the error, its causes, and potential solutions, ensuring a smooth installation process for ADIOS2 with ZFP support. Understanding and resolving this issue is crucial for researchers and developers who rely on ADIOS2 for high-performance data I/O and ZFP for efficient data compression.

Understanding the Issue

When attempting to install ADIOS2 2.10.2 with ZFP, the build process fails during the CMake configuration step. The error message indicates that CMake cannot find the necessary package configuration files for ZFP, namely ZFPConfig.cmake or zfp-config.cmake. This typically occurs when ZFP is not correctly installed or when its installation directory is not included in CMake's search paths. The error message, as shown in the provided log, clearly states:

CMake Error at cmake/DetectOptions.cmake:121 (find_package):
  Could not find a package configuration file provided by "ZFP" (requested
  version 0.5.3) with any of the following names:

    ZFPConfig.cmake
    zfp-config.cmake

This error halts the ADIOS2 installation, preventing users from leveraging ZFP's compression capabilities within their ADIOS2 workflows. To effectively troubleshoot this issue, it's essential to understand the role of CMake in the build process and how it locates external libraries and dependencies like ZFP. CMake uses find_package commands to locate these dependencies, relying on configuration files provided by the libraries themselves.

Prerequisites

Before diving into the solutions, ensure that the following prerequisites are met:

  1. Spack Package Manager: Spack should be correctly installed and configured on your system. Spack simplifies the process of building and installing scientific software, managing dependencies, and ensuring reproducibility. Visit the Spack documentation for installation instructions.
  2. ZFP Library: Verify that the ZFP library is installed on your system. If not, install it using Spack or your system's package manager. The version of ZFP should be compatible with the ADIOS2 version you are trying to install.
  3. CMake: CMake is a cross-platform build system generator. Ensure that CMake is installed and accessible in your system's PATH. Spack typically manages CMake as a dependency, so it should be available if you are using Spack.
  4. Compiler: A compatible C++ compiler (e.g., GCC, Intel Compiler) is required. Spack can manage compiler installations as well, ensuring that the correct compiler version is used for building ADIOS2 and its dependencies.

Steps to Reproduce the Issue

The issue can be reproduced by following these steps:

  1. Create a Spack Specification: Use the spack spec command to generate a specification for ADIOS2 version 2.10.2 with ZFP support. This command helps visualize the dependency tree and configuration options.

    $ spack spec -I adios2@2.10.2
    
  2. Install ADIOS2: Attempt to install ADIOS2 using the spack install command with the generated specification. This command triggers the build process, which includes the CMake configuration step.

    $ spack install adios2@2.10.2
    
  3. Observe the Error: During the CMake phase, the build process will likely fail with the error message indicating that the ZFP package configuration file cannot be found.

Potential Causes and Solutions

1. ZFP Not Installed or Not in CMake Path

Cause: The most common cause is that ZFP is either not installed on the system or, if installed, its installation directory is not in CMake's search path. CMake relies on the CMAKE_PREFIX_PATH variable to locate package configuration files.

Solution:

  1. Install ZFP using Spack: If ZFP is not installed, use Spack to install it. This ensures that ZFP and its dependencies are correctly managed.

    $ spack install zfp
    
  2. Verify ZFP Installation Path: Check the installation path of ZFP. Spack typically installs packages under its opt directory. For example:

    $ spack find zfp
    

    This command will show the installation path, which might look like /path/to/spack/opt/spack/linux-x86_64/zfp-0.5.5. Make sure to replace /path/to/spack with your Spack installation path.

  3. Set CMAKE_PREFIX_PATH: Ensure that the ZFP installation path is included in the CMAKE_PREFIX_PATH environment variable. You can set this variable before running the spack install command.

    $ export CMAKE_PREFIX_PATH=/path/to/spack/opt/spack/linux-x86_64/zfp-0.5.5:$CMAKE_PREFIX_PATH
    $ spack install adios2@2.10.2
    

    This command adds the ZFP installation path to CMAKE_PREFIX_PATH. If CMAKE_PREFIX_PATH is already set, the ZFP path is prepended to the existing value. This ensures that CMake searches the ZFP installation directory when looking for configuration files.

2. Incorrect ZFP Version

Cause: Another potential issue is using an incompatible version of ZFP. The ADIOS2 build system might require a specific version of ZFP, and if the installed version does not match, CMake may fail to find the configuration files.

Solution:

  1. Check ADIOS2 Requirements: Review the ADIOS2 build configuration to determine the required ZFP version. The error message often indicates the expected version (e.g.,
