Can you help me identify why libdxf.a fails to find strcasecmp or more interestingly strlen, as shown below. It's been over ten years since I've done any work with "C" so I'm pretty rusty.
gcc -I./src -g -O2 -DPACKAGE_NAME=\"\" -DPACKAGE_TARNAME=\"\" -DPACKAGE_VERSION=\"\" -DPACKAGE_STRING=\"\" -DPACKAGE_BUGREPORT=\"\" -DLINUX=1 -DSTDC_HEADERS=1 -DHAVE_SYS_TYPES_H=1 -DHAVE_SYS_STAT_H=1 -DHAVE_STDLIB_H=1 -DHAVE_STRING_H=1 -DHAVE_MEMORY_H=1 -DHAVE_STRINGS_H=1 -DHAVE_INTTYPES_H=1 -DHAVE_STDINT_H=1 -DHAVE_UNISTD_H=1 -DHAVE_LIMITS_H=1 -c src/dl_writer_ascii.cpp -o src/dl_writer_ascii.o

All comments are appreciated.
