Introduce a level of indirection and versioning in the config files
|
|
|
|
|
-------------------------------------------------------------------
|
|
|
|
|
|
|
|
|
|
`config.h` was split into `build_info.h` and `mbedtls_config.h`.
|
|
|
|
|
`build_info.h` is intended to be included from C code directly, while
|
2021-06-16 09:10:41 +02:00
|
|
|
`mbedtls_config.h` is intended to be edited by end users wishing to
|
2021-06-04 00:19:53 +02:00
|
|
|
change the build configuration, and should generally only be included from
|
|
|
|
|
`build_info.h`. This is because all the preprocessor logic has been moved
|
|
|
|
|
into `build_info.h`, including the handling of the `MBEDTLS_CONFIG_FILE`
|
|
|
|
|
macro.
|
|
|
|
|
|
|
|
|
|
Mandatory version symbols were introduced for `MBEDTLS_CONFIG_FILE` and
|
|
|
|
|
`MBEDTLS_USER_CONFIG_FILE`, `MBEDTLS_CONFIG_VERSION` and
|
|
|
|
|
`MBEDTLS_USER_CONFIG_VERSION` respectively. Both config files should include
|
|
|
|
|
a definiton of their respective version symbol, with a value of `1` to be
|
|
|
|
|
considered valid.
