Compiling the IXP1200_Apps, I get an error when arm-unknown-coff-ld tries to link objects to libraries: Linking main.o arm-unknown-coff-ld -o ipmm.coff /root/Vera/Runtime/ixp1200/sa/lib/crt0.o main.o ipmm.o /root/Vera/Libsck/lib/arm/libsck.a /root/Vera/Libesc/lib/arm/libesc.a /root/Vera/Runtime/ixp1200/sa/lib/libIXP1200.a /root/Vera/Libixprouter/sa/lib/libIXPRouter.a /root/Vera/Libcii/lib/arm/libcii.a -L/root/Vera/Libcii/lib/arm -L/root/Vera/Libesc/lib/arm -L/root/Vera/Libixprouter/sa/lib -L/root/Vera/Libsck/lib/arm -L/root/Vera/Runtime/ixp1200/sa/lib -L/usr/xcc/arm/lib/gcc-lib/arm-unknown-coff/2.95.2 -X -T /root/Vera/Runtime/ixp1200/sa/lib/coffarmIXP1200.x -lsck -lesc -lIXP1200 -lIXPRouter -lcii -lgcc /root/Vera/Libixprouter/sa/lib/libIXPRouter.a(control.o)(.text+0xb4):fake: undefined reference to `atoi' (..snip..) The control.c module of libIXPRouter archive use the atoi() function which seems not to be declared in any of those libraries. Do I need to rewrite the strtol() function from scratch and include the object into libIXPRouter.a or something is wrong with me? Thanks in advance. Bonelli Nicola
