1MODIFYING OPENSSL SOURCE 2======================== 3 4This document describes the way to add custom modifications to OpenSSL sources. 5 6 If you are adding new public functions to the custom library build, you need to 7 either add a prototype in one of the existing OpenSSL header files; 8 or provide a new header file and edit 9 [Configurations/unix-Makefile.tmpl](Configurations/unix-Makefile.tmpl) 10 to pick up that file. 11 12 After that perform the following steps: 13 14 ./Configure -Werror --strict-warnings [your-options] 15 make update 16 make 17 make test 18 19 `make update` ensures that your functions declarations are added to 20 `util/libcrypto.num` or `util/libssl.num`. 21 If you plan to submit the changes you made to OpenSSL 22 (see [CONTRIBUTING.md](CONTRIBUTING.md)), it's worth running: 23 24 make doc-nits 25 26 after running `make update` to ensure that documentation has correct format. 27 28 `make update` also generates files related to OIDs (in the `crypto/objects/` 29 folder) and errors. 30 If a merge error occurs in one of these generated files then the 31 generated files need to be removed and regenerated using `make update`. 32 To aid in this process the generated files can be committed separately 33 so they can be removed easily. 34
