I was packaging chromium-59.0.3053.3 . I worked around the problem described here, but I'd like to find the right long term solution.
I was hitting the following compile error: ../../ui/gfx/linux/client_native_pixmap_dmabuf.cc:39:27: fatal error: linux/dma-buf.h: No such file or directory #include <linux/dma-buf.h> Despite having sys-kernel/linux-headers-4.10 installed, I do not have that header. Interestingly, it is present in the tarball (gentoo-headers-base-4.10.tar.xz), but doesn't seem to get installed. This is the workaround I applied: <https://gitweb.gentoo.org/repo/gentoo.git/tree/www-client/chromium/files/chromium-dma-buf-r1.patch?id=f3d721fbb4127f17e836a1842cfdd2bf76f0d398> This is part of the chromium code in question: <https://cs.chromium.org/chromium/src/ui/gfx/linux/client_native_pixmap_dmabuf.cc?q=dma-buf.h+package:%5Echromium$&l=39&dr=C> #if LINUX_VERSION_CODE < KERNEL_VERSION(4, 6, 0) #include <linux/types.h> struct local_dma_buf_sync { __u64 flags; }; #define LOCAL_DMA_BUF_SYNC_READ (1 << 0) #define LOCAL_DMA_BUF_SYNC_WRITE (2 << 0) #define LOCAL_DMA_BUF_SYNC_RW \ (LOCAL_DMA_BUF_SYNC_READ | LOCAL_DMA_BUF_SYNC_WRITE) #define LOCAL_DMA_BUF_SYNC_START (0 << 2) #define LOCAL_DMA_BUF_SYNC_END (1 << 2) #define LOCAL_DMA_BUF_BASE 'b' #define LOCAL_DMA_BUF_IOCTL_SYNC \ _IOW(LOCAL_DMA_BUF_BASE, 0, struct local_dma_buf_sync) #else #include <linux/dma-buf.h> #endif Paweł
