Error Linking CXX executable ltp-file-transfer

[xzvf00]

I am building HDTN on a raspberry pi using the raspberry pi os terminal. I am currently in the HDTN/build directory and have executed cmake .. -DCMAKE_SYSTEM_PROCESSOR=arm After doing so, I executed make -j2 and it started building. However once it got to 41% it produced this error:

[ 40%] Building CXX object common/ltp/CMakeFiles/ltp-file-transfer.dir/apps/ltp_file_transfer/src/LtpFileTransferRunner.cpp.o
[ 41%] Linking CXX executable ltp-file-transfer
[ 41%] Built target ltp-file-transfer
make: *** [Makefile:149: all] Error 2

How can I resolve this issue? Thank you.
