Hello,
Toolchain arm-gnu-toolchain-11.3.rel1-x86_64-arm-none-eabi, downloaded from developer.arm.com/.../arm-gnu-toolchain-downloads
The following include:
#include <stdlib.h>
causes the error:
token "@" is not valid in preprocessor expressions
The reason is include/_newlib_version.h file, the Newlib version strings are defined as follows:
/* The newlib version in string format. */ #define _NEWLIB_VERSION "@NEWLIB_VERSION@" /* The newlib major version number. */ #define __NEWLIB__ @NEWLIB_MAJOR_VERSION@ /* The newlib minor version number. */ #define __NEWLIB_MINOR__ @NEWLIB_MINOR_VERSION@ /* The newlib patch level. */ #define __NEWLIB_PATCHLEVEL__ @NEWLIB_PATCHLEVEL_VERSION@
For the record, gcc-arm-11.2-2022.02-x86_64-arm-none-eabi has the following defines:
#define _NEWLIB_VERSION "4.1.0" #define __NEWLIB__ 4 #define __NEWLIB_MINOR__ 1 #define __NEWLIB_PATCHLEVEL__ 0
Hope this will be fixed soon.
