| Basic cgo functionality |
| ======================= |
| |
| opts_test |
| --------- |
| |
| Checks that different sets of options are passed to C and C++ sources in a |
| ``go_library`` with ``cgo = True``. |
| |
| dylib_test |
| ---------- |
| |
| Checks that Go binaries can link against dynamic C libraries. Some libraries |
| (especially those provided with ``cc_import``) may only have dynamic versions, |
| and we should be able to link against them and find them at run-time. |
| |
| dylib_test |
| ---------- |
| |
| Checks that Go binaries can link against dynamic C libraries that are only |
| available as a versioned shared library, like ``libfoo.so.1``. |
| |
| cc_libs_test |
| ------------ |
| |
| Checks that Go binaries that include cgo code may or may not link against |
| libstdc++, depending on how they're linked. This tests several binaries: |
| |
| * ``pure_bin`` - built in ``"pure"`` mode, should not depend on libstdc++. |
| * ``c_srcs`` - has no C++ code in sources, should not depend on libstdc++. |
| * ``cc_srcs`` - has some C++ code in sources, should depend on libstdc++. |
| * ``cc_deps`` - depends on a ``cc_library``, should depend on libstdc++ |
| because we don't know what's in it. |
| |
| race_test |
| --------- |
| |
| Checks that cgo code in a binary with ``race = "on"`` is compiled in race mode. |
| Verifies #1592. |
| |
| tag_test |
| -------- |
| |
| Checks that sources with ``// +build cgo`` are built when cgo is enabled |
| (whether or not ``cgo = True`` is set), and sources with ``// +build !cgo`` |
| are only built in pure mode. |
| |
| cdeps_link_test |
| --------------- |
| |
| Checks that libraries in ``cdeps`` are linked into the generated ``_cgo_.o`` |
| executable used to produce ``_cgo_imports.go``. Verifies `#2067`_. |
| |
| split_import_test |
| ----------------- |
| |
| Checks that when a package with ``cdeps`` is recompiled due to a split test, |
| the input files from ``cdeps`` are included in the recompilation and are passed |
| to the linker. Verifies `#2622`_. |
