Dear all: I use Ubuntu 9.10 with kernel 2.6.31.19 and I try to build drivers/media/video in 2.6.31.12 with kernel header 2.6.31.19 that I apt-get intall from web. ( I successfully build drivers/media/video in 2.6.31.12 source code. But I find the insmod told me the version is wrong. So I rebuild it with kernel header 2.6.31.19) My questions are: 1. I got the error message below when compiling: CC [M] /media/sdb1/software/linux/linux-2.6.31.12/drivers/media/video/tuner-core.o /media/sdb1/software/linux/linux-2.6.31.12/drivers/media/video/tuner-core.c:24:20: error: mt20xx.h: No such file or directory the problem comes from in 2.6.31.19/drivers/media/common, there is header files as mt20xx.h that tuner-core.c need. But these header files really exist under source code. Does that mean all the generic headers I apt-get from web will not include these headers I need? if so, what I should do next? (get complete source code of 2.6.31.19 from kernel.org? But I cannot see this version there. Could I use git to get this specific version?) thanks your help in advance, vichy -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
