devcontainer: add x86_64 OpenSSL dev libs for cross-compilation#3095
Conversation
The Solana SDK 2.3.x upgrade introduced a dependency on solana-secp256r1-program which requires openssl-sys. This breaks goreleaser cross-compilation on arm64 devcontainers targeting x86_64. Add libssl-dev:amd64 and set PKG_CONFIG_ALLOW_CROSS=1 so the openssl-sys build script can find the x86_64 OpenSSL headers.
