Compilation Issues with STM32 HAL Libraries in Strict ANSI-C Mode
Good day everyone, I'm in a bit of a hit and miss on something guys.
I have an embedded project that starts as a blank project with an empty
The HAL documentation states that it is written in Strict ANSI-C:
"The source code of drivers is developed in Strict ANSI-C, which makes it independent of the development tools. It is checked with the CodeSonarTM static analysis tool, fully documented, and MISRA-C 2004 compliant."
I understand Strict ANSI-C to mean C89, so I added the following GCC flags to my Makefile:
However, when I compile with these flags, I receive numerous errors and warnings. Without these flags, the code compiles without issues.
I'm very confused about this. Am I missing something, or is there a mistake in their documentation?
Here are some of the GCC compiler errors with the flags enabled, which appear repeatedly across many STM32 HAL files:
