License Headers: Set copyright to "Blender Authors", add AUTHORS Listing the "Blender Foundation" as copyright holder implied the Blender Foundation holds copyright to files which may include work from many developers. While keeping copyright on headers makes sense for isolated libraries, Blender's own code may be refactored or moved between files in a way that makes the per file copyright holders less meaningful. Copyright references to the "Blender Foundation" have been replaced with "Blender Authors", with the exception of `./extern/` since these this contains libraries which are more isolated, any changed to license headers there can be handled on a case-by-case basis. Some directories in `./intern/` have also been excluded: - `./intern/cycles/` it's own `AUTHORS` file is planned. - `./intern/opensubdiv/`. An "AUTHORS" file has been added, using the chromium projects authors file as a template.

File headers: SPDX License migration Use a shorter/simpler license convention, stops the header taking so much space. Follow the SPDX license specification: https://spdx.org/licenses - C/C++/objc/objc++ - Python - Shell Scripts - CMake, GNUmakefile While most of the source tree has been included - `./extern/` was left out. - `./intern/cycles` & `./intern/atomic` are also excluded because they use different header conventions. doc/license/SPDX-license-identifiers.txt has been added to list SPDX all used identifiers.

Build: add compatibility between precompiled libraries and new glibc On Linux, precompiled libraries may be made with a glibc version that is incompatible with the system libraries that Blender is built on. To solve this we add a few -ffast-math symbols that can be missing. Differential Revision: https://developer.blender.org/D6930 2020-02-25 13:05:09 +01:00

Build: change libc compatibility code to only be used for new glibc This way we can still use fast math functions. 2020-02-27 12:46:37 +01:00			`add_c_flag(-ffast-math)`

Fix compilation on Linux, glibc 2.34, and CentOS libraries A continuation of previous fix for malloc hooks which got removed from the new glibc library. The pre-compiled jemalloc has definitions which interpose hooks in glibc leading to linking errors with multiple hook definitions. A simple fix is to skip doing the workaround when using jemalloc from pre-compiled libraries. This will likely be revisited in the future, but for now it is important to fix compilation errors for developers. 2022-09-13 10:34:41 +02:00
