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 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
