Problem Solved..... For some reason, the video-buf.o module was exporting symbols prefaced with "gpl". The bttv.o module was looking for symbols without this prefix. So I editted the source video-buf.c and changed all of the "EXPORT_SYMBOL_GPL" statements to just "EXPORT_SYMBOL". I am sorry if I missed something somewhere.... But I found no mention anywhere on the video4linux list or on the net explaining this had to be done. In fact I find the lack of any installation documentation quite distressing --- Maybe I should write a howto? Note, I also had to patch the ksyms.c file in the kernel source as well in order to get rid of a get_user_pages unresolved symbol before this happened. Rett Walters ---- Previous message ---- Hello all: I have been trying for some time to upgrade a kernel to V4l2 (the older one, since my application hasn't been updated yet). I have installed a patch for 2.4.18 kernel, recompiled the kernel, and downloaded, and compiled sucessfully the bttv-0.8.46 drivers. Upon attempting to insmod them either manually or via the "update" script included with the source I get the following output: [root@regulus bttv-0.8.46]# ./update + grep videodev /proc/modules videodev 5984 0 (unused) + grep v4l2-common /proc/modules v4l2-common 4784 0 (unused) + grep i2c-core /proc/modules i2c-core 13312 0 [i2c-algo-bit] + grep i2c-algo-bit /proc/modules i2c-algo-bit 7168 0 i2c-core 13312 0 [i2c-algo-bit] + sudo /sbin/rmmod bttv rmmod: module bttv is not loaded + sudo /sbin/rmmod video-buf + sudo /sbin/insmod ./video-buf.o debug=1 + sudo /sbin/insmod ./bttv.o bttv_debug=0 vbi_debug=0 irq_debug=0 latency=64 fdsr=0 sloppy=1 chroma_agc=1 mmap=1 vbibufs=4 radio=0,1 ./bttv.o: unresolved symbol videobuf_read_stop ./bttv.o: unresolved symbol videobuf_streamon ./bttv.o: unresolved symbol videobuf_dma_pci_sync ./bttv.o: unresolved symbol videobuf_iolock ./bttv.o: unresolved symbol videobuf_querybuf ./bttv.o: unresolved symbol videobuf_dqbuf ./bttv.o: unresolved symbol videobuf_mmap_setup ./bttv.o: unresolved symbol videobuf_queue_init ./bttv.o: unresolved symbol videobuf_poll_stream ./bttv.o: unresolved symbol videobuf_waiton ./bttv.o: unresolved symbol videobuf_dma_pci_unmap ./bttv.o: unresolved symbol videobuf_reqbufs ./bttv.o: unresolved symbol videobuf_read_one ./bttv.o: unresolved symbol videobuf_dma_free ./bttv.o: unresolved symbol videobuf_mmap_mapper ./bttv.o: unresolved symbol videobuf_qbuf ./bttv.o: unresolved symbol videobuf_read_stream ./bttv.o: unresolved symbol videobuf_streamoff ./bttv.o: unresolved symbol videobuf_alloc [root@regulus bttv-0.8.46]# This has been quite perplexing, as I have been running into unresolved symbols alot while trying to get this upgraded. The video-buf.o module loads fine, which is where I assumed that these symbols are exported from, according to the source code. How do I resolve this issue? Any input would be greatly appreciated.
