> #### ⚠️ EOL NOTICE
>
> From April 2022, we don't support the C SDK capability. For more details, see our [Support Forum post](https://support.newrelic.com/s/hubtopic/aAX8W0000008d0r/q1-bulk-eol-announcement-fy23).

New Relic's C SDK provides a generic library you can customize to communicate with New Relic. Before you install New Relic's C SDK, make sure your system meets these requirements. Also refer to the [C SDK licenses documentation](https://docs.newrelic.com/docs/c-sdk-licenses).

Want to try out our C SDK? [Create a New Relic account](https://newrelic.com/signup) for free! No credit card required.

## Language versions [#language-release]

The C SDK allows you to instrument any application on Linux, provided:

-   You must have access to the source code.
-   The target language must be able to import C libraries.

You can use the C SDK to create instrumentation for applications written in C and C++. You can also use it in languages like Perl, which are implemented in C or C++, and in any language that has a foreign function interface with C.

## Operating environments [#operating-systems]

The C SDK works in 64-bit Linux operating systems with:

-   gcc 4.8 or higher
-   glibc 2.17 or higher
-   Kernel version 2.6.26 or higher
-   libpcre 8.20 or higher
-   libpthread
-   cmake 2.8 or higher

Compiling the New Relic daemon requires Go 1.7 or higher.

## License key [#license]

You will need a New Relic license key for the account you want to report data to.

## Processor type [#processor]

-   Intel (and compatible) platforms only
-   Support for SSE2 instructions is required

## Security requirements [#security]

As a standard [security measure for data collection](https://docs.newrelic.com/docs/accounts-partnerships/new-relic-security/security/data-security), your app server must support SHA-2 (256-bit). SHA-1 is not supported.

## Database and instance-level performance [#datastores]

You can collect [instance details for a variety of databases and database drivers](https://docs.newrelic.com/docs/apm/applications-menu/features/analyze-database-instance-level-performance-issues). You can also view slow query trace details for the following SQL-based database platforms:

-   Firebird
-   Informix
-   Microsoft SQL Server
-   MySQL
-   Oracle
-   Postgres
-   SQLite
-   Sybase
