[ptxdist] System libraries in target-sysroot

[ptxdist] System libraries in target-sysroot

[Alan Martinovic]

Hi there,

as I understood, there are two sysroots involved in the build system
process.

sysroot-target: in the BSP project directory
sysroot-arm-v5te-linux-gnueabi: in the compiler directory structure
(changes depending on the compiler)

How do the system libraries and headers (example. stdio.h) find there
way from sysroot-arm-v5te-linux-gnueabi to the actual target device
sysroot (not sysroot-target on the host machine)?

I couldn't locate them neither in sysroot-target or root.

Is that a technical issue on having them in sysroot-target?
Somehow I would conceptually expect to find them there, but feel free to
correct/comment on this opinion.

Be Well :)
Alan

They are found via standard include paths the compiler and the linker are using 
(since the compiler, assembler, linker and the runtime C library form 
the 'toolchain').

'sysroot-target' contains all BSP related parts which must be built in 
addition.

Jürgen
