/tmp/instance-0/output-1/host/bin/mips64el-linux-g++ -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64  -Os       -Wall -Wextra -Wno-missing-field-initializers -Wno-unused-parameter -g -DSHA="not available" -o edid-decode edid-decode.cpp parse-base-block.cpp parse-cta-block.cpp parse-displayid-block.cpp parse-ls-ext-block.cpp parse-di-ext-block.cpp parse-vtb-ext-block.cpp -lm
edid-decode.cpp: In member function 'std::__cxx11::string edid_state::dtd_type()':
