But what compiler built it? > > Think about 3 years from now. There is a hard fault on a product. You need to debug it. But you have upgraded your compiler 3 times. How would you generate an elf to debug it to do postmortem debugging? If you list the compiler in the build you can. If you want these features, the same info already provide by the predefined macros: https://gcc.gnu.org/onlinedocs/cpp/Common-Predefined-Macros.html#Common-Predefined-Macros ``` __GNUC__ __GNUC_MINOR__ __GNUC_PATCHLEVEL__ __VERSION__ ``` It's simple to directly reference them here: https://github.com/apache/incubator-nuttx/blob/master/libs/libc/misc/lib_utsname.c#L113 ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
