./configure failing due to syntax error in configure file.

Wilfredo — Tue, 05 Jul 2016 00:30:25 -0000

Hi,

I haven't been able to compile squash-fs, the process fails during ./configure, with the following message:

./configure: line 13582: syntax error near unexpected token pkgconfig_XZ,liblzma,' ./configure: line 13582: PKG_CHECK_MODULES(pkgconfig_XZ,liblzma,'

I double-checked the PLATFORMS and README files, and I believe I installed all required packages.

Thanks,

Wilfredo

#4 mksquashfs -ef not excluding hidden directories

Nevermind, i realised that you have to create an "excludes" file and put your files / directory's inside of it.

mksquashfs -ef not excluding hidden directories

kidharb — Sat, 21 Mar 2015 10:41:51 -0000

Hi,

My directory structure contains a hidden folder namely ".git".
Is it possible to exclude hidden directory's with the "-ef" option?

I am using mksquash version 4.0

Compression options

Steve Kieu — Mon, 22 Jul 2013 04:11:09 -0000

Two points:

the lzo compress we use is very slow (test it, it even slower than the default gzip 9 in my machine) and it produce even bigger squashfs image compare with the faster lzo compression

Thus I suggest we can use: lzo1x_1_15_compress instead of lzo1x_999_compress. I tested myself, it is much faster to compress and the output file size is even smaller.

Add an option to allow gzip level rather than hard coded to 9. For example Gzip 4 which make it much less CPU time and produce just a bit bigger size but tehre is no way to set it now

(Well I did a quick hack by let mksquashfs read the environment GZIP_LEVEL and use it like this in gzip_wrapper.c

   char * gzlevel = getenv("GZIP_LEVEL");
    if (! gzlevel) gzlevel = "4";
    res = deflateInit(stream, atoi(gzlevel));

but it should be a permanent option. I had a quick look of how it should be implemented but find it hard to implement as it talk to a generic wrapper - and it handles it a bit complex to me)

Thanks

unsquashfs endianness

Yuji1 Saeki — Fri, 12 Oct 2012 08:06:44 -0000

I've compiled squashfs-tools and have a problem with endianness. If I specify -be BigEndian for any mksquashfs I can't unpack it with unsquashfs.

mkdir test
mksquashfs 'test' 'test.sq' -all-root -be
unsquashfs 'test.sq'

Reading a different endian SQUASHFS filesystem on test.sq
Can't find a SQUASHFS superblock on test.sq

empty inode entry in 2.2r2 causes filesystem failure

A_v — Wed, 14 Jun 2006 00:57:44 -0000

Hi,

I am trying to use the squashfs version 2.2r2 to
generate a compressed filesystem image, using the
following:

/PATH_TO_TOOLS/squashfs-tools/mksquashfs
/tmp/DIR_TO_SQUASH/* output.img -noappend -nopad -info
-le -all-root

The problem is that sometimes I see that sometimes that
there is an empty directory inode that is created:

"mksquashfs: directory inode 0x912"

Whenever this happens the filesystem image that is
created can't be read.

I was wondering if anyone else had seen this problem
and if they have, is there a workaround for it?

Thanks,
AV.
