Compiling mkfs.jffs2

Hello All,

I am having a little problem compiling the source code for mkfs.jffs2 in the nios 2 ide. I downloaded the source from psyent.com and everytime I try to compile the source, the IDE complains that it cannot find the zlib.h file. I did a file search and found the zlib.h in the linux files directory. I manually added that directory to the include path and then it complains that the funcitions deflate, deflate_init, inflate, etc cannot are undefined in compr_zlib.c Is there something missing in the source or is is something I am doing wrong.

    Nothing is missing from the source, you're doing something wrong -- build it from the

    shell command line. Remember, you're not cross-compiling in this case.

    Hey Scott,

    Thanks for the reply. Why dont I have to cross compile. THis program does run on NIOS right, so doesnt that mean cross compiling?

    It _can_ run under uclinux -- but it's normally used on a development host to create

    the jffs2 file system image that gets programmed into flash.

    BTW: You should probably build the tool on a unix host (linux, solaris) -- under cygwin

    the file permissions (most notably the execute bits) don't get set.
