我們生活周遭存在太多太多的 embedded system ,過去 embedded system 有專屬的 OS,現在 linux 也可以應用在嵌入式環境,不過本版將廣泛討論所有嵌入式系統不只 linux 喔,歡迎有這方面經驗或有興趣的朋友一同進來討論。

Q: I get the following error message:
qc-driver.c:51: linux/version.h: No such file or directory
qc-driver.c:52: parse error
or
.../include/linux/config.h:4: linux/autoconf.h: No such file or directory
or
sed: can't read /usr/src/linux/Makefile: No such file or directory
or
Makefile:26: /usr/src/linux/.config: No such file or directory
A: You must install Linux kernel source code corresponding
to the kernel you will be running with the camera driver.
The source must be configured and depencies must have been
created. Typically you can just install the kernel source
package that comes with your distribution. If you're instead using
virgin kernel in /usr/src/linux-x.y.zz, you must first copy
kernel configuration file to /usr/src/linux-x.y.zz/.config,
then go to the directory and run "make oldconfig" and "make dep".
This should create the missing linux/version.h file.
Some more help for Redhat/Mandrake users:
If you get a lot of errors on mandrake or red hat when
you do a make, it may be because you didn't install a
full development version, meaning your kernel sources
are not there.
This worked for me
urpmi kernel-source
urpmi kernel-headers
urpmi kernel-doc
urpmi is your friend, it will find the CD that it needs
to get this. Some rpms may be installed already, big
deal, do this then do a make, it worked on mandrake 8.2!
------------------------------------------------------------
Q: And finally, I look for /dev/video* (to set the videodev on
gnomemeeting) and I haven't any videodevice.
A:
mknod /dev/video0 c 81 0
chmod a+r /dev/video0
ln -s /dev/video0 /dev/video
------------------------------------------------------------
Q: quickcam.c:2099: too few arguments to function `remap_page_range_R2baf18f2'
Damian Ivereigh posted a patch to be able to compile
the driver for RedHat 9.0 but I don't know how to do
A: Due to qc-usb 0.5.1, this should be now fixed. If you
still encounter this problem, and
if you're using qc-usb, just compile it with command
USER_OPT=-DHAVE_VMA=1 make all
Otherwise (if you're using older qce-ga):
1. Download qce-ga-0.40d.tar.gz package and save
the patch
wget http://www.ee.oulu.fi/~tuukkat/quickcam/qce-gq-rh9.patch
wget http://www.ee.oulu.fi/~tuukkat/quickcam/qce-ga-0.40d.tar.gz
2. Extract the package:
tar xvfz qce-ga-0.40d.tar.gz
3. Enter the source directory
cd qce-ga-0.40d
4. Apply the patch:
patch -s -p1 < ../qce-gq-rh9.patch
5. patch complains that the patch is reversed. Answer yes:
Reversed (or previously applied) patch detected! Assume -R? [n] y
6. Then compile and install the driver normally
make
./quickcam.sh
------------------------------------------------------------
Q: I don't have permissions for /dev/video?
A: Easiest way to add permissions is to do
chmod a+rw /dev/video?
as root. Altenatively, especially on Debian, users belonging
to the "video" group can access video devices. In this case,
you might instead prefer issuing
addgroup <yourlogin> video
as root and then login as normal user. Check in which groups
your are in with
id -a
------------------------------------------------------------
Q: My log files keep filling up (but the driver works fine)!
A: use "qcset debug=0" to disable all possible messages.
If it doesn't help, send e-mail to mailing lists showing
the exact error message that fills your logs.
(especially "frame lost" message is uninteresting, it is
known to happen with some programs and will be fixed later.
------------------------------------------------------------
Q: quickcam.o: kernel-module version mismatch
quickcam.o was compiled for kernel version 2.4.18
while this kernel is version 2.4.18-686-smp.
A: Then edit "Makefile" in the kernel source directory and change the line 4
from
EXTRAVERSION =
to
EXTRAVERSION = -686-smp
--or if this doesn't help--
Go to /usr/src/linux-2.4/include/linux/version.h and change the
UTS_RELEASE to match the output of "uname -r" on the command line
(should be 2.4.18-686-smp). Then recompile the module and then the
insmod will work perfectly :) [from Mark]
------------------------------------------------------------
Q: I want to reverse engineer an USB camera. How?
A: Run *ugh* Windoze *cough* drivers with a USB stream
capture program, like http://sourceforge.net/projects/usbsnoop/
Then send the same commands to the camera from Linux.
------------------------------------------------------------
Q: I added IEEE1394 card and now Quickcam doesn't work?
A: The card driver overwrites /dev/video0..2, use
insmod ./quickcam.o video_nr=3
and then /dev/video3 with Quickcam.
Create /dev/video3 with mknod if necessary.

>Choose a configuration file in extras/Config/ and then run

A: The solution to this seems obvious. I "cp ./vendors/Lineo/uCdimm/config.uClibc
./vendors/Lineo/uCsimm" and make again with the same settings as above. The
library compile bombs out a little further along...

A
recent posting suggests a solution. Rather than copy individual missing files,
I untared an older uClibc-snapshot into "./uClibc" and then overcopied with the
uClibc-0.9.10 tree. The make goes further still and stops with...
use the uClib of uClinux-dist-20050311.tar.gz replace it,because I can make it in that.

Now I'm lost. I made a wild guess which is probably wrong and created a
directory called ./uClibc/lib and recompiled...

My host system is RH7.2 and I've installed m68k-elf-tools-20020218.tar.gz under
"/" and uClinux-dist-20020306.tar.gz under "/opt".

/bin/sh: ucfront-gcc: command not found
A
/*intrenet A
I think you have'nt installed the toolchain properly.
Simply type arm-linux-gcc in one linux console.
if still gives the error "command not found",reinstall
the toolchain.
If it still doesn't work, you may have to modify the
PATH environmental varaiable to include the
toolchain's path to it.*/
