build2 Package for tinyexr

This project is a build2 package repository that provides access to tinyexr, a small, single-header-only C++ library to load and save OpenEXR (.exr) images.

Usage

Make sure to add the stable section of the cppget.org repository to your project's repositories.manifest to be able to fetch this package.

:
role: prerequisite
location: https://pkg.cppget.org/1/stable
# trust: ...

If the stable section of cppget.org is not an option then add this Git repository itself instead as a prerequisite.

:
role: prerequisite
location: https://github.com/build2-packaging/tinyexr.git

Add the respective dependency in your project's manifest file to make the package available for import.

depends: libtinyexr ^1.0.9

The library can be imported by the following declaration in a buildfile.

import tinyexr = libtinyexr%lib{tinyexr}

Configuration

There are no configuration options available.

Issues and Notes

• The test data in the libtinyexr-tests package is more than 240 MiB in size and, as a consequence, not publishable on cppget.org because it is too large. Thus, it is not declared as the mandatory external tests package of libtinyexr. It can and should still be used for local testing and for CI runs.
• By using the macros TINYEXR_USE_THREAD or TINYEXR_USE_OPENMP, tinyexr is able to support multithreading by either using C++11 threads or OpenMP. Please note that the package's build system is not automatically adding dependencies and flags for pthread or OpenMP.
• Currently, the configuration of dependencies for tinyexr is not handled by the package's build system. tinyexr uses miniz by default and it does not provide specific tests for other configurations. Furthermore, support for zlib and stb's implementation of zlib only seems to be useful when using tinyexr without a build system as drop-in header file. So, for now, please refrain from using the following macros.
  • TINYEXR_USE_MINIZ
  • TINYEXR_USE_STB_ZLIB
• tinyexr adds ZFP compression only as an experimental support on Linux and MacOS. Currently, it is not supported by the packgage's build system. Hence, please, refrain from using the following macro.
  • TINYEXR_USE_ZFP
• The compilation of the tests package libtinyexr-tests is not supported on target configurations windows*-clang** due to the wrong encoding of win32-filelist-utf16le.inc. Presumably, this will not be fixed as it is an upstream issue. Please note that the compilation and execution of the basic tests still works on these configurations. Thus, the library should work without flaws on those platforms.
• For Windows, the file '日本語.exr' and the test utf8filename had to be removed from distribution and execution, respectively. Please, see this issue for more information.
• Emscripten is not supported.
• The examples are not supported by the package's build system, yet.
• For now, the fuzzers are not compiled and run.
