The size of software builds can often be a concern for developers, particularly in embedded systems or other resource-constrained environments. Recently, a change was made to the wolfSSL library that has resulted in smaller build sizes when used with the popular cURL library.
The change in question was made in a pull request to the wolfSSL library on GitHub, specifically pull request #6320. Which removes the need for using:
–enable-opensslextra
and instead only requires:
–enable-opensslextra=x509small CPPFLAGS=-DHAVE_CURL
This compiles out a lot of compatibility layer functionality (used for ripping out and replacing OpenSSL) that is not needed by cURL. Mainly this change is to reduce the code footprint size of the wolfSSL library. This change can be especially beneficial in resource-constrained environments where smaller builds are crucial.
