I'm trying to set up a cross-compiler for ARM. I followed this tutorial and I'm at the point now where I can run the cross compiler and get:
arm-unknown-eabi-gcc (GCC) 4.8.4 Copyright (C) 2013 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
But when I try to ./configure Dropbear (the software I'm trying to compile) I get an error:
checking for gcc... /home/josh/opt/cross/bin/arm-unknown-eabi-gcc checking whether the C compiler works... no configure: error: in `/home/josh/src/dropbear-2016.74': configure: error: C compiler cannot create executables See `config.log' for more details
I believe this is because I don't yet have a standard library for the target system, because the tutorial I was following mentions:
Note how this compiler is not able to compile normal C programs. The cross-compiler will spit errors whenever you want to #include any of the standard headers (except for a select few that actually are platform-independent, and generated by the compiler itself). This is quite correct - you don't have a standard library for the target system yet!
How can I obtain/build a standard library for my target?
