Instead of using `target_link_modules`, which does magic that we no
longer need, because we only have 1 library we install, and all binaries
we build link statically because they need access to internal symbols.
It doesn't work at all, because we're missing something in the net code
to do with endian conversions. I haven't investigated, yet, but at least
now we have a failing test that can be investigated.
Also moved to cmake 3.5 at minimum. CMake will stop supporting lower
versions than that, soon.
Also moved to C11 from C99 to get `static_assert`.
Also made a network ERROR into a WARNING. It triggers on FreeBSD.
* `crypto_memcmp` was replaced by more specific functions. We never want
to compare arbitrary amounts of data this way. We use these functions
to compare key material.
* apidsl has been bothering people, so now we un-bother them. You're
welcome.
* Added the memlock/unlock functions from the New Group Chats branch.
* Remove some system dependencies in crypto_core_mem.c.
* Renamed UPPERCASE_NAMES to Snake_Camel_Case names.
* Don't overwrite the CMAKE_MODULE_PATH
* Allow linking libsodium statically with MSVC
* Allow finding libsodium the normal way on MSVC
* Allow using pthreads4w for pthreads on MSVC
* Fall back to find_package if pkg_find_module fails
* Don't pass incompatible compile flags to MSVC
* Also try to find Opus and libvpx using their canonical names
* Support building using conan
* Allow pkg_use_module to take a list of libraries to look for
* Build for Windows on Appveyor using conan
* Use fully static build for the bootstrap daemon.
* Store a sha256sum of the binary in the repo.
* Updated documentation for it.
* Add support for fully static build in cmake.
* Enable the docker build on every PR, so we catch changes to the
checksum. I realise this is adding toil, but having the checksum is
valuable for security of released binaries.
Also, added some #defines to make symbols visible that are in BSD but not
in UNIX. Solaris needs these, since it's fairly strict with its symbol
visibility in system headers.
This caused us to build everything 2-4 times, now we only build it 1-2
times (depending on selection of static/shared builds). The disadvantage
is that now it's more up to the reviewer to ensure modularity (we still
catch it in the bazel build, though).
Instead of hard-erroring when we don't find dependencies, we just don't
build the things requested and print a warning. This is less annoying to
users because we enable a bunch of things by default. This way, we can at
least build something with the default "cmake" invocation.
This way, developers compile toxcore, toxav, and toxencryptsave as C++ at
least once at home, reducing the likelyhood of running into travis
failures where we compile as C++ in the windows build.
This library contains all the code for the old libtoxcore, libtoxav,
libtoxdns, and libtoxencryptsave. The build for toxav is still optional,
and disabling it causes libtoxcore to simply not contain those symbols
and the pkg-config file to not include opus and vpx as dependencies.
Tests are not actually ran on appveyor for now, since they all fault for
some reason. For now, we just build them. Also, some tests are disabled
on msvc entirely, because they don't even compile. We'll need to look
into those, later. They are disabled using `MSVC_DONT_BUILD`.
Also a little bit of refactoring:
- Moved add_cflag and friends from CMakeLists.txt to a separate
AddCompilerFlag module.
- Build the spectest SUT if msgpack is found, even if spectest itself is
not found, so once it exists, users can run it themselves or
reconfigure cmake.
this updates the version-sync script to generate proper SO versions
which will be used by cmake and libtool to create version symlinks
on the system when a library is installed as well as setting the SO
version in the binary.
To see what this does, you have to configure tox with a prefix:
./configure --prefix=/tmp/tox-with-libtool
mkdir cbuild && cd cbuild && cmake -DCMAKE_INSTALL_PREFIX=/tmp/tox-with-cmake ..
Then run `make && make install`.
in both instances you should see the following installed in `lib/`:
libtoxcore.so -> libtoxcore.so.1.4.0
libtoxcore.so.1 -> libtoxcore.so.1.4.0
libtoxcore.so.1.4.0
inside the binary the soname should be the one with .1 and it should not
contain the full version:
$ objdump -p libtoxcore.so.1.4.0 | grep SONAME
SONAME libtoxcore.so.1
We disable the ones that fire, so we can use -Werror. We can then
investigate each warning individually and see whether to fix it or to
keep silencing it.
Compiling as C++ changes nothing semantically, but ensures that we don't
break C++ compatibility while also retaining C compatibility.
C++ compatibility is useful for tooling and additional diagnostics and
analyses.
