Description

Current bundled libyuv seems to have build issue on older gcc, e.g:

../../yuv/source/row_common.cc: In function ‘void libyuv::YuvPixel(uint8, uint8, uint8, uint8*, uint8*, uint8*, const libyuv::YuvConstants*)’:
../../yuv/source/row_common.cc:1256: error: invalid types ‘const signed char __vector__[int]’ for array subscript
../../yuv/source/row_common.cc:1257: error: invalid types ‘const signed char __vector__[int]’ for array subscript
../../yuv/source/row_common.cc:1258: error: invalid types ‘const signed char __vector__[int]’ for array subscript
../../yuv/source/row_common.cc:1259: error: invalid types ‘const signed char __vector__[int]’ for array subscript
../../yuv/source/row_common.cc:1260: error: invalid types ‘const short int __vector__[int]’ for array subscript

Also in the source code around the compile error location, there is this warning:

// Caveat GCC 4.2 to 4.7 have a known issue using vectors with const.

The issue seem to be fixed already, as described here. So let's update our libyuv version.

  • Status changed from new to closed
  • Resolution set to wontfix

It seems that this issue was fixed at some point but for some reason it was reverted back. So the changeset r5633 in this ticket just updates the libyuv version.
