ARM GCC cross-compiler fedora 22

Question

I'm running fedora LXDE and I'm trying to cross-compile for ARM for my research. After looking through the internet I downloaded the packages:arm-linux-gnu-cpp and arm-linux-gnu-binutils and tried to use them to compile a hello world C program. I got the following:

[aejjeh@localhost ARMtests]$ arm-linux-gnu-gcc -v hello.c

Then, after some digging around on the internet I found that arm-linux-gnu-gcc can only build kernel applications and not user applications. I also found that there is a package called arm-none-eabi-gcc, so I installed it and tried to use it. This time I get the following verbose output:

and if I try to compile a C code that doesn't use any printfs I got the following:

[aejjeh@localhost ARMtests]$ arm-none-eabi-gcc hello.c
/usr/lib/gcc/arm-none-eabi/5.2.0/../../../../arm-none-eabi/bin/ld: cannot find crt0.o: No such file or directory
/usr/lib/gcc/arm-none-eabi/5.2.0/../../../../arm-none-eabi/bin/ld: cannot find -lc
collect2: error: ld returned 1 exit status

If anyone can point out what I'm doing wrong or if there is a different way I can get the cross-compiler working please let me know.

Answer 1

I recently needed to set up a fedora box for arm cross-compiling. I wanted to use the dnf packages instead of downloading linaro binaries like I have in the past. dnf search arm eventually led me to this package list:

$ sudo dnf install gcc-arm-linux-gnu binutils-arm-linux-gnu glibc-arm-linux-gnu

$ arm-linux-gnu-gcc hello.c 
$ file a.out
a.out: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 3.2.0, BuildID[sha1]=4fa9ce3405cf64f9019f0c39e82fc97d8f4e5190, with debug_info, not stripped

Edit: I noticed that sys/ include files aren't picked up by default. There may be a better way, but passing -I works in a pinch:

$ arm-linux-gnu-gcc -I /usr/arm-linux-gnu/include srcfile.c

Edit2: The need for passing -I is discussed in https://bugzilla.redhat.com/show_bug.cgi?id=1456209

Edit3: My original answer didn't install C++ or the cross-compiled libstdc++-devel package. The C++ cross compiler is easy:

$ sudo dnf install gcc-c++-arm-linux-gnu

But oddly, there doesn't seem to be a package for the C++ library readily available. My best guess is that you'd need to download the C++ library source and compile it with the cross compilers.
