Informative Report - Build error with librocksdb-sys 5.7.1 and rocksdb ^0.8.0 on various OS's #584

Closed heunglee closed 6 years ago

heunglee commented 6 years ago

Please note that this issue is not what grin needs to fix. It is more like informative report on building grin in AWS instances at the time of writing. There seems problem in linker to native library, librocksdb-sys. AMI has dev tools configured for amazon specifics and there seems some conflicts in clang part. EPEL was enabled and clang was installed to fix the build error. But the error was persistent.

Hardware: AWS EC2 m.large OS: AMI

Before upgrading to rocksdb 0.8.0+, compiling grin on the ec2 instance above was passed and grin was operational. After git pull and cargo build for update to rocksdb 0.8.0+ and librocksdb-sys 5.7.1, cargo build failed. It was not successful with cargo clean and cargo build either. The error log is in the link, https://pastebin.com/G9sGLmR5.
