When walking through the directions
for setting up the kernel so it can be patched by the FreeS/WAN build,
it mentions that with RedHat, you can pull the configuration used for the
defaul kernels out of the config directory. What it doesn't explicitly
mention is that you must still run menuconfig to load that config and
create a few miscellaneous support files. Otherwise, when you run the
make dep, it will die with this error message:
*** No rule to make target '/usr/src/linux/include/linux/autoconf.h' needed by 'usr/src/linux/include/modules/signal.ver'. Stop
I found this answer on the
FreeS/WAN list. Just copy the config file, run make
menuconfig, select exit, then save the configuration. Also, make
sure that you do the make mrproper before you copy
the redhat configuration into place, otherwise it will be deleted, since
that is one of the files that mrproper removes.
