just before i head off for coffee, might as well dump this to the list and see what someone has to say. i successfully built a small-endian SH3 toolchain and, as part of the build, here's the contents of the build-glibc/csu directory (you'll see shortly why i'm listing that particular directory): [csu]$ file *.o # what are file types? note "LSB" abi-note.o: ELF 32-bit LSB relocatable, Hitachi SH, version 1 MathCoPro/FPU/MAU Required (SYSV), not stripped check_fds.o: ELF 32-bit LSB relocatable, Hitachi SH, version 1 (SYSV), not stripped crt1.o: ELF 32-bit LSB relocatable, Hitachi SH, version 1

since this was a small-endian build, everything is LSB. start over, change sh3.dat to reflect big-endian ("-ml" -> "-mb"), start the build and eventually: ... big snip here ...

this build be MSB? sure looks like this is the problem -- that some compiles are still being done as little-endian. so ... what mind-numbingly obvious flag or option have i overlooked? or is this not the problem? rday ------ Want more information?
