MODIFYING OPENSSL SOURCE
|
|
========================
|
|
|
|
This document describes the way to add custom modifications to OpenSSL sources.
|
|
|
|
If you are adding new public functions to the custom library build, you need to
|
|
either add a prototype in one of the existing OpenSSL header files;
|
|
or provide a new header file and edit
|
|
[Configurations/unix-Makefile.tmpl](Configurations/unix-Makefile.tmpl)
|
|
to pick up that file.
|
|
|
|
After that perform the following steps:
|
|
|
|
./Configure -Werror --strict-warnings [your-options]
|
|
make update
|
|
make
|
|
make test
|
|
|
|
`make update` ensures that your functions declarations are added to
|
|
`util/libcrypto.num` or `util/libssl.num`.
|
|
If you plan to submit the changes you made to OpenSSL
|
|
(see [CONTRIBUTING.md](CONTRIBUTING.md)), it's worth running:
|
|
|
|
make doc-nits
|
|
|
|
after running `make update` to ensure that documentation has correct format.
|
|
|
|
`make update` also generates files related to OIDs (in the `crypto/objects/`
|
|
folder) and errors.
|
|
If a merge error occurs in one of these generated files then the
|
|
generated files need to be removed and regenerated using `make update`.
|
|
To aid in this process the generated files can be committed separately
|
|
so they can be removed easily.
