@dgarske I've added the Espressif updates to include.am to #5956 in 50820b6.

It seemed more relevant there and as this PR's append_wolfssl_git_version.sh is specifically not included in the the dist since there will be no git info to append.

I've converted this to a draft to consider other options.

Is this something that might be useful for the entire project not just Espressif?

I would definitely like to see version information everywhere. If it were up to me, I'd have date/version info in each source file.

Admittedly this PR modifying source code is a little wonky.

Thanks @douzzer for the makefile idea as implemented for Espressif in #6018

If everyone likes the idea, I'll create a new PR that includes runtime display in version.h

Can one of the admins verify this patch?

As #6018 was merged, I think it is a better idea to have a more soft version detection, something other than modification of source files.

See the LIBWOLFSSL_SAVE_INFO CMake function for examples of saving various interesting version attributes at compile time.

Here's an example of displaying those values at runtime in the Espressif embedded environment:

#if defined(LIBWOLFSSL_VERSION_GIT_HASH)
    ESP_LOGI(TAG, "LIBWOLFSSL_VERSION_GIT_HASH = %s", LIBWOLFSSL_VERSION_GIT_HASH);
#endif

#if defined(LIBWOLFSSL_VERSION_GIT_SHORT_HASH )
    ESP_LOGI(TAG, "LIBWOLFSSL_VERSION_GIT_SHORT_HASH = %s", LIBWOLFSSL_VERSION_GIT_SHORT_HASH);
#endif

#if defined(LIBWOLFSSL_VERSION_GIT_HASH_DATE)
    ESP_LOGI(TAG, "LIBWOLFSSL_VERSION_GIT_HASH_DATE = %s", LIBWOLFSSL_VERSION_GIT_HASH_DATE);
#endif
