That is correct behavior in most - cases because the header files bundled with your toolchain (such as - stdio.h) are probably not correct for use with NuttX. Certain - header files, such as setjmp.h, may be needed from your toolchain. - In that case, one solution is to copy that file from your toolchain - into the NuttX include directory. If you prefer to use the stdint.h - and stdbool.h header files from your toolchain, those could be copied - too. Using most other header files from your toolchain would probably - cause errors. + Some toolchains are built with header files extracted from a C-library + distribution (such as newlib). For those toolchains, NuttX must be + compiled without using the standard header files that are distributed + with your toolchain. This prevents including conflicting, incompatible + header files (such as stdio.h). + + Certain header files, such as setjmp.h and varargs.h, may still be + needed from your toolchain, however.
