Linux linking errors

[pierricgimmig]

On Linux, I get:

git/sentry-native/src/backends/sentry_backend_crashpad.cpp:55: undefined reference to operator delete(void*, unsigned long)'`

What fixed it for me was to link with stdc++:

CMakeLists.txt

-       set(_SENTRY_PLATFORM_LIBS "dl" "rt")
+       set(_SENTRY_PLATFORM_LIBS "dl" "rt" "stdc++")

Thanks for the report! We're building the Native SDK on many Linux setups and haven't had a situation where we need to specify a particular stdlib implementation (except if someone is required to use a specific implementation over an environmental default).

This is typically defined via your toolchain, and we'd love to keep the toolchain-preferred stdlib (as we do now) instead of enforcing libstdc++ for everyone (since that can lead to non-obvious behavior in toolchains that have other default stdlibs like libc++).

Can you provide more context on which setup (Linux distribution, toolchain packages, CMake config-phase output) you had to specify a C++ standard library? I know that some "embedded" toolchains require further specification (in which case, I recommend preparing a simple CMake toolchain file that includes everything you need).
