undefined reference to MemStream::MemStream....

[mzs555557]

when I use libfuzzer in libafl to fuzz xpdf4.04. there are some issues:( , how can i solve it?
the build command is

./target/release/libafl_cxx ./fuzz_JBIG2.cc ./xpdf-4.04/build/*/*.a -I ./xpdf-4.04/xpdf/ -I xpdf-4.04/goo -I xpdf-4.04/fofi/ -I xpdf-4.04/splash/ -I xpdf-4.04/ -I xpdf-4.04/build/ -o fuzzer_pdfload -lm -ldl -lpthread -lstdc++ -lgcc -lutil -lrt

the issue report is :

try this (note the reordering of arguments so includes are first, and static libs follow the .cc)

./target/release/libafl_cxx -I ./xpdf-4.04/xpdf/ -I xpdf-4.04/goo -I xpdf-4.04/fofi/ -I xpdf-4.04/splash/ -I xpdf-4.04/ -I xpdf-4.04/build/ -o fuzzer_pdfload ./fuzz_JBIG2.cc ./xpdf-4.04/build/*/*.a -lm -ldl -lpthread -lstdc++ -lgcc -lutil -lrt
