JFFS2 kernel support

[Altera_Forum]

Hello all 

I'm trying to add jffs2 support to a kernel (3c120 dev board) and I'm facing an strange problem. If I checked in jffs2 support in menuconfig, _after_ compiling the kernel core and  _while compiling_ the apps , the compile process barfs   || ( touch mtd-utils/.sgbuilt_user && make -C mtd-utils ) || exit $? make: se ingresa al directorio `/home/eugenio/uCLinux-MMU/nios2-linux/uClinux-dist/user/mtd-utils' unset CC CFLAGS CPPFLAGS CROSS LDFLAGS; make -C 606f38a2221648ca5c5fa292c9f71d2ddd59fa66/ WITHOUT_XATTR=1 SUBDIRS= BUILDDIR=$PWD/build-606f38a2221648ca5c5fa292c9f71d2ddd59fa66-host/ TARGETS=" mkfs.jffs2" make: se ingresa al directorio `/home/eugenio/uCLinux-MMU/nios2-linux/uClinux-dist/user/mtd-utils/606f38a2221648ca5c5fa292c9f71d2ddd59fa66' mkdir -p /home/eugenio/uCLinux-MMU/nios2-linux/uClinux-dist/user/mtd-utils/build-606f38a2221648ca5c5fa292c9f71d2ddd59fa66-host/ gcc -I./include -DWITHOUT_XATTR -D_FILE_OFFSET_BITS=64 -O2 -g -Wall -Wextra -Wwrite-strings -Wno-sign-compare -c -o /home/eugenio/uCLinux-MMU/nios2-linux/uClinux-dist/user/mtd-utils/build-606f38a2221648ca5c5fa292c9f71d2ddd59fa66-host/compr_lzo.o compr_lzo.c -g -Wp,-MD,/home/eugenio/uCLinux-MMU/nios2-linux/uClinux-dist/user/mtd-utils/build-606f38a2221648ca5c5fa292c9f71d2ddd59fa66-host/.compr_lzo.c.dep compr_lzo.c:29:23: error: lzo/lzo1x.h: No existe el fichero o el directorio compr_lzo.c: In function ‘jffs2_lzo_cmpr’: compr_lzo.c:51: error: ‘lzo_uint’ undeclared (first use in this function) compr_lzo.c:51: error: (Each undeclared identifier is reported only once compr_lzo.c:51: error: for each function it appears in.) compr_lzo.c:51: error: expected ‘;’ before ‘compress_size’ compr_lzo.c:54: warning: implicit declaration of function ‘lzo1x_999_compress’ compr_lzo.c:54: error: ‘compress_size’ undeclared (first use in this function) compr_lzo.c:56: error: ‘LZO_E_OK’ undeclared (first use in this function) The strange thing is that it tries to compile mkfs.jffs2 using my x86 gcc compiler :confused: If I try to disable mtd-utils, it doesn't mind; same error while compiling mkfs.jffs2 in mtd-utils which I have previously disabled.... Adding kernel support for MTD and user apps. support for mtd-utils works fine.  No errors. It only happens when adding jffs2 kernel support and while compiling mkfs.jffs2 (mtd-utils enabled or not) Any hints? TIA

--- Quote Start ---  If both CPUs try to start Linux, things are going very wrong. This can't work as the NIOS Linux is not SMP enabled and will not be in forseeable future, as the NIOS CPU lacks many features necessary for SMP support.   There might be some threads on multiple CPUs here, you might want to read them.   And for questions you should start a thread with an appropriate subject line.  -Michael  --- Quote End ---     hi thank you   my system with 2 cpus is running very well  one running uclinux and another c   thanks
