How to fix an error when building OpenWRT under MIPS?

Question

C++ / C#

Good day.
I'm trying to build OpenWRT under MIPS and I'm running into an error. I make a Black Swift microcomputer according to the instructions ( link ).
I enter make V=99 and after 20 minutes I get this error:

make[3] -C package/system/fstools compile
 make[3] -C package/boot/uboot-envtools compile
 make[3] -C package/libs/libreadline compile
 make[3] -C package/devel/gdb compile
 make[3] -C package/libs/gettext compile
 make[3] -C package/libs/libiconv compile
 make[3] -C package/libs/libtool compile
 make[3] -C package/libs/cyassl compile
make -r world: build failed. Please re-run make with V=s to see what's going on
/home/aleksey/openwrt/include/toplevel.mk:171: ошибка выполнения рецепта для цели «world»
make: *** [world] Ошибка 1

This is what toplevel.mk:171 contains

@+$(PREP_MK) $(NO_TRACE_MAKE) -r -s prereq
  @( \
    cp .config tmp/.config; \
    ./scripts/config/conf --defconfig=tmp/.config -w tmp/.config Config.in > /dev/null 2>&1; \
    if ./scripts/kconfig.pl '>' .config tmp/.config | grep -q CONFIG; then \
      printf "$(_R)WARNING: your configuration is out of sync. Please run make menuconfig, oldconfig or defconfig!$(_N)\n" >&2; \
    fi \
  )
  @+$(ULIMIT_FIX) $(SUBMAKE) -r [email protected]

endif

I'm using Ubuntu 15.04 myself.
Unfortunately, I'm not selenium in like this, so I'm asking for help.
Thank you for attention.
Sincerely, Alex.

The solution to the problem is very simple. If during assembly it tries to download any library and does not find it, you just need to find this particular version (I copied the name) and look for it yourself. Then just put it in /openwrt/dl/ and run make V=99 again.

Answer 1

Read what they themselves wrote: "Please run make menuconfig, oldconfig or defconfig!" - tried?

Answer 2

so a 404 error does not bother? that he can not download the source? Either tell him where to get cyassl-3.2.0.zip or, when configuring, specify the assembly without this lib
