Hi all,

I have noticed an issue with absolute paths in exported targets: Background:

1. During Secure build some header file paths are added to include directories of tfm_config (and some other targets) – for example TARGET_CONFIG_HEADER_FILE, PROJECT_CONFIG_HEADER_FILE 2. Then tfm_config is exported to install directory and is used in Non-Secure build

There are several issues here:

1. In Non-Secure build exported tfm_config uses absolute paths that ware defined during secure build. This is an issue as NS-interface (api_ns folder) may be built on another machine. 2. Also looking into api_ns folder – I don’t see those files being exported (for example TARGET_CONFIG_HEADER_FILE, PROJECT_CONFIG_HEADER_FILE are not exported to api_ns) * Looking into a code I was able to identify at least these defines that are effected (but list may be longer):

i. TARGET_CONFIG_HEADER_FILE

ii. PROJECT_CONFIG_HEADER_FILE

iii. MBEDTLS_PSA_CRYPTO_CONFIG_FILE

iv. MBEDTLS_CONFIG_FILE

Is there a plan to somehow solve this issue? If so, then what is the schedule on it?
