I have a solution. I posted a fix to be able to compile dietlibc in my host system, to the above Puppy Forum link. Quoting: ------------------------ Fixed it! Have to export these environment variables, so gcc knows where the system headers are, so that "-nostdinc" knows what to ignore! I thought that gcc would already know that, given that it is compiled by ubuntu as multilib. Code: # export C_INCLUDE_PATH=/usr/include/arm-linux-gnueabihf # export CPLUS_INCLUDE_PATH=/usr/include/arm-linux-gnueabihf # # /usr/lib/arm-linux-gnueabihf/diet/bin/diet -v gcc -nostdinc helloworld.c -o helloworld gcc -nostdlib -static -L/usr/lib/arm-linux-gnueabihf/diet/lib-arm -L/usr/lib/diet/lib /usr/lib/arm-linux-gnueabihf/diet/lib-arm/start.o -nostdinc helloworld.c -o helloworld -isystem /usr/lib/arm-linux-gnueabihf/diet/include -D__dietlibc__ /usr/lib/arm-linux-gnueabihf/diet/lib-arm/libc.a -lgcc /usr/lib/arm-linux-gnueabihf/diet/lib-arm/libc.a helloworld.c:4:1: warning: return type defaults to ‘int’ [-Wimplicit-int] main() ^ /usr/lib/arm-linux-gnueabihf/diet/lib-arm/libc.a(vprintf.o): In function `vprintf': (.text+0x2c): warning: warning: the printf functions add several kilobytes of bloat. # ------------------------ Now back onto T2. Compiling dietlibc, Stage-1, gcc is looking at those same headers in the host system. So, it looks like I need to export those same environment variables in dietlibc.conf. I'm not sure how to do that though.
