I'm porting some existing functional Keil code over to the GNU compiler, and I'm running into some odd linker errors. The code compiles fine, but I get the linker errors listed below. They look like they refer to library functions, so I suspect I may not have all the "#include" files I need. Any ideas? Thanks, Randall Aiken Linker error output: Linking: moat.elf arm-elf-gcc -mcpu=arm7tdmi -I. -gdwarf-2 -DROM_RUN -Os -Wall -Wcast-align -Wcast-qual -Wimplicit -Wpointer-arith -Wswitch -Wredundant-decls -Wreturn-type -Wshadow -Wunused -Wa,-adhlns=crt0.lst -MD -MP -MF .dep/moat.elf.d crt0.o main.o CLI.o I2C.o ISR.o Serial.o SPI.o --output moat.elf -nostartfiles -Wl,-Map=moat.map,--cref -lc -lm -lc -lgcc -TLPC2124-ROM.ld c:/winarm/bin/../lib/gcc/arm-elf/4.1.0/../../../../arm-elf/lib\libc.a(fr eer.o): In function `_malloc_trim_r':mallocr.c:(.text+0x48): undefined reference to `_sbrk_r' :mallocr.c:(.text+0x64): undefined reference to `_sbrk_r' :mallocr.c:(.text+0x84): undefined reference to `_sbrk_r' c:/winarm/bin/../lib/gcc/arm-elf/4.1.0/../../../../arm-elf/lib\libc.a(ma kebuf.o): In function `__smakebuf':makebuf.c:(.text+0x3c): undefined reference to `_fstat_r' :makebuf.c:(.text+0x110): undefined reference to `isatty' c:/winarm/bin/../lib/gcc/arm-elf/4.1.0/../../../../arm-elf/lib\libc.a(ma llocr.o): In function `_malloc_r':mallocr.c:(.text+0x424): undefined reference to `_sbrk_r' :mallocr.c:(.text+0x4cc): undefined reference to `_sbrk_r' c:/winarm/bin/../lib/gcc/arm-elf/4.1.0/../../../../arm-elf/lib\libc.a(st dio.o): In function `__sclose':stdio.c:(.text+0xc): undefined reference to `_close_r' c:/winarm/bin/../lib/gcc/arm-elf/4.1.0/../../../../arm-elf/lib\libc.a(st dio.o): In function `__sseek':stdio.c:(.text+0x30): undefined reference to `_lseek_r' c:/winarm/bin/../lib/gcc/arm-elf/4.1.0/../../../../arm-elf/lib\libc.a(st dio.o): In function `__swrite':stdio.c:(.text+0x84): undefined reference to `_lseek_r' :stdio.c:(.text+0xac): undefined reference to `_write_r' c:/winarm/bin/../lib/gcc/arm-elf/4.1.0/../../../../arm-elf/lib\libc.a(st dio.o): In function `__sread':stdio.c:(.text+0xd0): undefined reference to `_read_r' collect2: ld returned 1 exit status Make: *** [moat.elf] Error 1
