Solution to this error is nowhere on Internet!!??

Hi folks,

I am trying to cross compile windows wallet for an altcoin, the altcoin is POS and uses the zercoin protocol. I was able to recitfy the small level errors during compilation, but then I got an error which is nowhere mentioned on internet on any forum or any support page. It dispalys:

Code:

i686-w64-mingw32-g++ -c -O3 -msse2 -w -Wall -Wextra -Wno-ignored-qualifiers -Wformat -Wformat-security -Wno-unused-parameter -frandom-seed=wwtccoin -D_MT -DWIN32 -D_WINDOWS -DBOOST_THREAD_USE_LIB -DBOOST_SPIRIT_THREADSAFE -DSTATICLIB -DUSE_UPNP=0 -I"/home/ubuntu/build/wwtccoin/src/leveldb/include" -I"/home/ubuntu/build/wwtccoin/src/leveldb/helpers" -DHAVE_BUILD_INFO -I"/home/ubuntu/build/wwtccoin/src" -I"/home/ubuntu/build/wwtccoin/src"/obj -I"/home/ubuntu/staging/include" -I"/home/ubuntu/staging" -o obj/zerocoin/Accumulator.o zerocoin/Accumulator.cpp

I even tried creating directory obj/zercoin before running the build script, but the error seems to be going nowhere!!!

One possible hinit I got from this website (https://sourceforge.net/p/mingw-w64/bugs/689/), but am not sure about this. Anyone who has any idea please guide me, any kind of help is highly appreciated.
