Question

I’m totally new to compiling drivers for linux and I got some problems !

I’m trying to compile a driver for a usb device.

Result:

[thayoz@lacalpc13 linux]$ make
for i in driver lib qrng ; do cd $i && (make all || exit ) && cd ..; done
make[1]: Entering directory /home/thayoz/Desktop/untitled folder/Quantis-USB/src/linux/driver'
make -C /usr/src/kernels/ M=/home/thayoz/Desktop/untitled folder/Quantis-USB/src/linux/driver V=1 modules
make[2]: Entering directory/usr/src/kernels'
make[2]: * No rule to make target folder/Quantis-USB/src/linux/driver'.  Stop.
make[2]: Leaving directory/usr/src/kernels'
make[1]: * [all] Error 2
make[1]: Leaving directory `/home/thayoz/Desktop/untitled folder/Quantis-USB/src/linux/driver'
/bin/sh: line 0: cd: lib: No such file or directory
/bin/sh: line 0: cd: qrng: No such file or directory
make: *** [all] Error 1

I don't know what's wrong ???

Answer 1

Typically something like:

make -C <directory to kernel source> M=<directory to module/driver source> modules
make -C <directory to kernel source> M=<directory to module/driver source> modules_install

is sufficient.

Did your driver come with a makefile? Are you compiling against the proper kernel sources, the right version, for instance?
