Arch Linux User Repository

I couldn't find a way to realy get it working... the compilation seems to fail again, but because of missing kernel parts.

Here is a manual walkthrough to compile it manually:

# cd/mkdir to compile directory (e.g. ~/src/archlinux-svn/)
# svn checkout --depth=empty svn://svn.archlinux.org/packages
# cd packages
# svn update linux
# cd linux/repos/core-x86_64
# makepkg -o
# cd src/linux-?.??/
# sed -i -- 's/# CONFIG_NCP_FS is not set/CONFIG_NCP_FS=m\nCONFIG_NCPFS_PACKET_SIGNING=y\n# CONFIG_NCPFS_IOCTL_LOCKING is not set\nCONFIG_NCPFS_STRONG=y\nCONFIG_NCPFS_NFS_NS=y\nCONFIG_NCPFS_OS2_NS=y\nCONFIG_NCPFS_SMALLDOS=y\nCONFIG_NCPFS_NLS=y\nCONFIG_NCPFS_EXTRAS=y/g' .config
# cp /usr/lib/modules/`uname -r`/build/Module.symvers .
# make scripts
# make fs/ncpfs/
# make modules SUBDIRS=fs/ncpfs
# sudo make modules_install SUBDIRS=fs/ncpfs
# sudo insmod fs/ncpfs/ncpfs.ko
# sudo depmod
# sudo modprobe ncpfs

After 4.16 the path changed a bit as ncpfs was moved to staging.

# cd/mkdir to compile directory (e.g. ~/src/archlinux-svn/)
# svn checkout --depth=empty svn://svn.archlinux.org/packages
# cd packages
# svn update linux
# cd linux/repos/core-x86_64
# makepkg -o
# cd src/linux-?.??/
# sed -i -- 's/# CONFIG_NCP_FS is not set/CONFIG_NCP_FS=m\nCONFIG_NCPFS_PACKET_SIGNING=y\n# CONFIG_NCPFS_IOCTL_LOCKING is not set\nCONFIG_NCPFS_STRONG=y\nCONFIG_NCPFS_NFS_NS=y\nCONFIG_NCPFS_OS2_NS=y\nCONFIG_NCPFS_SMALLDOS=y\nCONFIG_NCPFS_NLS=y\nCONFIG_NCPFS_EXTRAS=y/g' .config
# cp /usr/lib/modules/`uname -r`/build/Module.symvers .
# make scripts
# make drivers/staging/ncpfs/
# make modules SUBDIRS=drivers/staging/ncpfs
# sudo make modules_install SUBDIRS=drivers/staging/ncpfs
# sudo insmod drivers/staging/ncpfs/ncpfs.ko
# sudo depmod
# sudo modprobe ncpfs

good and bad news.

the ncpfs-module is compiling again.

BUT i seem to have forgot that i made changes to the source to fix the compilation with options. I'll have to look at this tomorrow. But that should be no big deal.

Hi,
thank you for the idea with the kernel! I switched to the lts version and now it is working again. I they don't ditch the these functions in the lts-kernel as well.

Hi,

almost forgot that i am at a course the next 2 days, so i'll investigate into it (hopefully) wednesday.

Regarding the vm: i couldn't find another way, besides using an old kernel or forcing your novell admin to enable samba or nfs support.

Sadly mine doesn't care...

Hi,
I highly appreciate your work here and really hope you will find a way to fix the present problem.

P.s. Are there any other alternatives than a VM?

Thank you. And yes, who uses ncpfs these days ... errr wait. It would be nice mounting the shares on my notebook at work. In the meantime I have to stick to my VM.

I got the same error some days ago on my notebook.

seems like the kernel ditched to functions "kill_pid" and "recalc_sigpending" some time ago. But that's only a quick guess, have to figure out if there is a patch anywhere for ncpfs. But i honestly doesn't have much hope, because ncpfs is abandoned.

Will repost back as soon as i've got time to investigate into it. Hopefully next week when i'm back at work.

Feel free to remind me then, i will surely forget it untill then ;)

Hi,
getting build errors. Do you have any advices?
