arm-linux-gnu-gcc fatal error: stdio.h: No such file or directory

Question

These are the files in /usr/bin

[root@xilinx bin]# ls -ld arm*
-rwxr-xr-x. 1 root root  691752 Feb  5  2013 arm-linux-gnu-addr2line
-rwxr-xr-x. 1 root root          


        

Answer 1

The problem here, it seems, is that you installed the compiler toolchain for the target, but didn't install a standard library for the target. You need a standard C library compiled specifically for your target platform. Either find a pre-compiled from the same place you found the compiler toolchain, or download one and cross-compile using the target toolchain.

When you have a standard C library for the target, use the flag -I (that's uppercase i) to tell the compiler where to find the header files, and the -L flag to tell the linker where to find the libraries, and e.g. -lc (that's the lower-case L) to tell the linker to link with the library. Something like

$ arm-linux-gnu-gcc -I/usr/local/target/include myinit.c -L/usr/local/target/lib -lc

Answer 2

This got fixed for me by installing "arm-none-eabi-newlib"

$ sudo yum install arm-none-eabi-newlib

It contained the required files in the right path.

Answer 3

The most likely issue here is that the sysroot path wasn't set when this cross compiler was generated. The toolchain developers have their own reasons for doing so. You can confirm by doing

$ arm-linux-gnu-gcc -print-sysroot
 /not/exist

The toolchain developers expect us to use the standard environment variables such as ${CXX} ${CC} to cross compile. They would usually have a script provided for this purpose that among other things does the following.

$ export SDKTARGETSYSROOT=/path/to/sysroots/armv7at2hf-neon-fslc-linux-gnueabi

$ export CC="arm-linux-gnu-gcc -march=armv7-a -mthumb -mfpu=neon -mfloat-abi=hard --sysroot=$SDKTARGETSYSROOT"

So, for compiling your *.c program, in this case, myinit.c, you would do.

$ ${CC} myinit.c

Or if you like me are old school would do

$ arm-linux-gnu-gcc -march=armv7-a -mthumb -mfpu=neon -mfloat-abi=hard --sysroot=$SDKTARGETSYSROOT myinit.c
