For the daily build of V4L2 I've made a little script to test if the ABI changed. The scripts I use are part of this archive: https://hverkuil.home.xs4all.nl/logs/scripts.tar.bz2 Specifically stabs-parser.pl and build.sh. The build.sh script is the main shell script that builds media for all the various architectures. At line 499 it creates a little test.c source that is basically a union with all the various top-level data structs used by v4l2. It then compiles it using the -gstabs compiler option and feeds the test.s to the stabs-parser. The output looks like this: v4l2_bt_timings: struct(124) { width@0(4) height@4(4) interlaced@8(4) polarities@12(4) pixelclock@16(8) hfrontporch@24(4) hsync@28(4) hbackporch@32(4) vfrontporch@36(4) vsync@40(4) vbackporch@44(4) il_vfrontporch@48(4) il_vsync@52(4) il_vbackporch@56(4) standards@60(4) flags@64(4) picture_aspect@68(8) cea861_vic@76(1) hdmi_vic@77(1) reserved[]@78(46) } v4l2_bt_timings_cap: struct(104) { min_width@0(4) max_width@4(4) min_height@8(4) max_height@12(4) min_pixelclock@16(8) max_pixelclock@24(8) standards@32(4) capabilities@36(4) reserved[]@40(64) } v4l2_buf_type:T0=eV4L2_BUF_TYPE_VIDEO_CAPTURE:1,V4L2_BUF_TYPE_VIDEO_OUTPUT:2,V4L2_BUF_TYPE_VIDEO_OVERLAY:3,V4L2_BUF_TYPE_VBI_CAPTURE:4,V4L2_BUF_TYPE_VBI_OUTPUT:5,V4L2_BUF_TYPE_SLICED_VBI_CAPTURE:6,V4L2_BUF_TYPE_SLICED_VBI_OUTPUT:7,V4L2_BUF_TYPE_VIDEO_OUTPUT_OVERLAY:8,V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE:9,V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE:10,V4L2_BUF_TYPE_SDR_CAPTURE:11,V4L2_BUF_TYPE_SDR_OUTPUT:12,V4L2_BUF_TYPE_META_CAPTURE:13,V4L2_BUF_TYPE_PRIVATE:128,} v4l2_buffer: struct(68) { index@0(4) type@4(4) bytesused@8(4) flags@12(4) field@16(4) timestamp@20(8) timecode@28(16) sequence@44(4) memory@48(4) m union(4) { offset@0(4) userptr@0(4) planes*@0(4) fd@0(4) }@52(4) } length@56(4) reserved2@60(4) reserved@64(4) } v4l2_capability: struct(104) { driver[]@0(16) card[]@16(32) bus_info@48(32) version@80(4) capabilities@84(4) device_caps@88(4) reserved[]@92(12) } It shows the sizes and offsets of all the fields. In your case compiling this program for 32 bit and 64 bit and parsing the stabs info should result in the same layout. It's not elegant perhaps, but it works well. Regards, Hans
