Hi,
I am using buildroot 2017.08-rc3 to build a rootfs for minnowboard
max. What I did is:
$ make minnowboard_max_defconfig
$ make menuconfig
Select "Target packages" -> "File system and flash utilities" -> simicsfs
$ make
The error message is:
buildroot/output/build/simicsfs-1.18/./hostfs_file.c:67:43: error:
?struct file? has no member named ?f_dentry?; did you mean ?f_owner??
DPRINT1("hostfs: hostfs_read %ld\n", file->f_dentry->d_inode->i_ino);

pgoff_t index = pos >> PAGE_CACHE_SHIFT;
<snip>
Although the README in the simicsfs 1.18 package says: Linux kernel
2.6.12 and later only. I believe this package does not build for
latest kernel like v4.12.2.

Bin

Unfortunately, simicsfs is no longer available at http://download.simics.net/pub/simicsfs-1.18.tar.gz, where Buildroot currently downloads it. The build only succeeds because we have a backup of this tarball at http://sources.buildroot.net. In addition, when you look at http://www.cs.sfu.ca/~fedorova/Tech/simics-guides-3.0.26/simics-user-guide-unix/topic33.html, the https://www.simics.net/pub/simicsfs.tar.gz now redirects to Windriver. So it seems like Windriver has now taken over the development of this tool, which generally isn't a very good sign in terms of openness. So I guess that if you need simicsfs, compatible with Linux 4.12, you'll have to patch the source code yourself. Of course, such a patch would be welcome in Buildroot, so that other users could benefit from it.

To be honest, since the source code is no longer available online, I'm not sure it's really worth keeping this package in Buildroot. Let's see if Bin gets some feedback from Windriver about putting the tarball back online, publicly available. If there is no feedback, we'll drop the package I believe.

Here is the situation: The latest simicsfs kernel module (v1.22) supports latest kernel, and is available in the simics open source package. However they are moving away from the simicsfs kernel module, replacing it with the user mode Simics Agent (Matic). They've seen that the kernel module has required too much maintenance work. For this reason they don't want to encourage use of it. Regards, Bin ^ permalink raw reply [flat|nested] 10+ messages in thread
