[gentoo-user-es] modulo cloop en gentoo

[Jose Zamora]

saludos:

Estoy tratando de compilar el módulo de cloop, hasta ahora he realizado 
lo siguiente.

cloop-0.68 # emerge cloop

Calculating dependencies ...done!
 >>> emerge (1 of 1) sys-apps/cloop-0.68 to /
 >>> md5 src_uri ;-) cloop_0.68-3.tar.gz
 >>> Unpacking source...
 >>> Unpacking cloop_0.68-3.tar.gz to /var/tmp/portage/cloop-0.68/work
 >>> Source unpacked.
 * /usr/src/linux is a symbolic link
 * Determining the real directory of the Linux kernel source code
 * Building for Linux 2.4.22-gentoo-r7 found in /usr/src/linux
 * You have not enabled the zlib compression and/or decompression options
 * in your Linux kernel.
 *
 * You must configure both options to be compiled into your kernel; cloop
 * will not compile if the zlib options are compiled as modules

!!! ERROR: sys-apps/cloop-0.68 failed.
!!! Function badconfig, Line 39, Exitcode 0
!!! (no error message)

Al parecer me falta compilar el módulo zlib dentro del kernel lo que me 
extraña es que tengo soporte
CONFIG_ZLIB_INFLATE=y
CONFIG_ZLIB_DEFLATE=m

Tambien estoy usando el kernel 2.6 el cual dice que no puede ser usado 
con este módulo. Pero según la documentación de knoppix si se podria. 
http://www.knoppix.net/docs/index.php/cloop

En base a esta documentación he decidido compilar el módulo a mano.

#cp /usr/portage/distfiles/cloop_0.68-3.tar.gz /usr/src/
#cd /usr/src/
#tar -xvzf cloop_0.68-3.tar.gz

Alguno de ustedes a podido dar soporte cloop al  su kernel?.

Gracias por cualquier ayuda..
