I have downloaded lzo-2.00 package and have installed it linux kernel 2.6 version. Now I want to include the lzo library in the source code of linux.
According to the instructions given in the package, I have copied the files (minilzo.c,minilzo.h,lzoconf.h,lzodefs.h)in the source directory(/mm),added minilzo.o to my Makefile and have included(#include minilzo.h) from my program.

But when I compile the kernel,I am getting errors.
Errors:
->limits.h:No such file or directory
->assert.h:No such file or directory

Plz kindly help me in this problem!!!!
Its very urgent....

Welcome to LQ.

""According to the instructions given in the package..""
Which instructions ? ?
Where did you read about copying files to linux-2.6.xx/mm/ ? ?

Reading this http://www.oberhumer.com/opensource/lzo/ , it seems
that lzo-2.0x is a user space library. The files you mention from
minilzo-2.0: also meant for user space applications, not kernel ?

http://www.oberhumer.com/opensource/lzo/download/
http://www.oberhumer.com/opensource/...zo-2.03.tar.gz
>>> lzo-2.03.tar.gz

http://free-electrons.com/blog/lzo-kernel-compression/ :
"" .. features in Linux 2.6.30 :
new compression options have been recently added to the kernel.""

Example 2.6.32, the files using the lzo algorithm looks like ..
find linux-2.6.32.6/ -name *lzo*
linux-2.6.32.6/fs/jffs2/compr_lzo.c
linux-2.6.32.6/lib/lzo/lzo1x_compress.c ←
linux-2.6.32.6/lib/lzo/lzodefs.h
linux-2.6.32.6/lib/lzo/lzo1x_decompress.c ←
linux-2.6.32.6/crypto/lzo.c
linux-2.6.32.6/include/linux/lzo.h

The headers, you are missing : limits.h, assert.h ..
Please tell, which Linux, you are using. And version please.
http://www.linuxquestions.org/linux/...Ask_a_Question
And also tell which kernel, this is about. Full version please.

I am using Fedora_Core7 and linux kernel version-2.6.21.

The instructions you asked were given in the 'Readme' file of the minilzo package under the lzo package. I am sending you some of the instructions given in the file. Hope this would help you in understanding my problem.

I've created miniLZO for projects where it is inconvenient to
include (or require) the full LZO source code just because you
want to add a little bit of data compression to your application.

miniLZO implements the LZO1X-1 compressor and both the standard and
safe LZO1X decompressor. Apart from fast compression it also useful
for situations where you want to use pre-compressed data files (which
must have been compressed with LZO1X-999).

miniLZO consists of one C source file and three header files:
minilzo.c
minilzo.h, lzoconf.h, lzodefs.h

To use miniLZO just copy these files into your source directory, add
minilzo.c to your Makefile and #include minilzo.h from your program.
Note: you also must distribute this file (`README.LZO') with your project.
