I tried brandelfing, but that didn't work. There's some weird symbols in there: 00000000 DF *UND* 00000023 GLIBC_2.0 fprintf 00000000 DF *UND* 000000f8 GLIBC_2.0 fflush 00000000 DF *UND* 000001b4 GLIBC_2.0 malloc 00000000 DF *UND* 00000058 GLIBC_2.0 memmove 00000000 DO *UND* 00000004 GLIBC_2.0 stderr 00000000 DF *UND* 0000020d GLIBC_2.0 abort 00000000 DF *UND* 00000027 GLIBC_2.0 memcpy 00000000 w DF *UND* 000000ac GLIBC_2.1.3 __cxa_finalize 00000000 DF *UND* 00000043 GLIBC_2.0 memset So it looks like I'm close... objcopy -R kept the GLIBC_* references in place, alas, so that didn't work, as suggested elsewhere in this thread. The above list is small, but has hree bad entries: fprintf, fflush and stderr. So that may present a problem for me if these functions are ever called. Warner
