install driver for ricoh r5u870 webcam

Question

I'm trying to install the driver for the webcam for my Sony laptop. I got the driver from here, and I followed the installation guide. But I got the following error when I type in make:

~/Downloads/r5u870 $ make
make -C /lib/modules/3.13.0-24-generic/build M=/home/xxx/Downloads/r5u870 V=0 modules
make[1]: Entering directory `/usr/src/linux-headers-3.13.0-24-generic'

make[1]: Leaving directory `/usr/src/linux-headers-3.13.0-24-generic'

I neglected it and continued through the following steps, but the system still couldn't find the webcam, so I guess it didn't install. What should I do?

Answer 1

the r5u870 project have been updated. you could go to the project home page and get the new url. the project is hosted on github now.

the x86 version works. you can download it by clicking "download zip" in the right area of the github page, and other steps are just same as before.

if you are using the x64 version of linux, you may try the master branch on github, but it may not work, since the author said he doesn't have a x64 machine to develop and test.
