Yes -- I've gotten to the point where I've made a new kernel and used the
distributed romdisk (whose login password is different!) but when I went to
actually compile the romdisk files instead of using the binaries supplied, I
run into the problem.
Until this point I have not used buildenv.
After using buildenv I have the same problem. However I thought I'd give it
all another shot, so I rebuild the kernel from the supplied sources as well
as uC-libc and uC-libm. I am seeing the same problem building uC-libc,
which makes me wonder if it worked teh first time around and I had just not
The problem (doing a make in uC-libc:)
[quite a lot of compile info, and a LOT of "warning: xxx (eg __FD_ISSET)
redefined) warnings], then the failure:
clnt_tcp.c: In function `readtcp':
clnt_tcp.c:407: structure has no member named `__bits'
clnt_tcp.c:419: warning: passing arg 3 of `select' from incompatible pointer
clnt_tcp.c:419: warning: passing arg 4 of `select' from incompatible pointer
make: *** [clnt_tcp.o] Error 1

auth_none.o clnt_generic.o clnt_perror.o
make: Leaving directory `/opt/uClinux/uC-libc/rpc'
make: *** [rpc] Error 2
This is precisely the same error I get when trying to build the romdisk
Something I have noted is that all the redefinitons seem to come from
types.h in the include/gnu subdirectory conflicting with
include/linux/posix_types. Is this normal?

In a word, no. :-) While I know that Slack now has the RPM utility and
utils like alien exist, RPM is just plain nasty in my opinion. 'sides, I
have cross-compiled before (uClinux/Coldfire to be exact), I think I just
have forgotten something dumb here.
Thanks for the informative reply, I hadn't really taken a good look at
buildenv until now and it looks like it can simplify this greatly!
