Even after copying the missing header to /usr/include/linux/ on my
system, I’m getting build failures:
../../ui/gfx/linux/client_native_pixmap_dmabuf.cc: In function ‘void
gfx::{anonymous}::PrimeSyncStart(int)’:
../../ui/gfx/linux/client_native_pixmap_dmabuf.cc:47:29: error: variable
‘gfx::{anonymous}::PrimeSyncStart(int)::local_dma_buf_sync sync_start’ has
initializer but incomplete type
struct local_dma_buf_sync sync_start = {0};
^~~~~~~~~~
../../ui/gfx/linux/client_native_pixmap_dmabuf.cc:49:22: error:
‘LOCAL_DMA_BUF_SYNC_START’ was not declared in this scope
sync_start.flags = LOCAL_DMA_BUF_SYNC_START | LOCAL_DMA_BUF_SYNC_RW;
^~~~~~~~~~~~~~~~~~~~~~~~
It appears LOCAL_DMA_BUF_SYNC_* are not defined in that header.
I’m temporarily working around the issue with the following patch to
chromium:
