【中文标题】在 Mac M1 上从 erlang 调用加载 Snowflake ODBC 驱动程序时出错：odbc.connect

【英文标题】：Error loading Snowflake ODBC Driver on Mac M1 from erlang call :odbc.connect

【问题描述】：

我在 arm64 Mac m1 上的 elixir 应用程序中加载雪花驱动程序时遇到问题（在 x86 上它工作顺利）。 已安装：

unixodbc 带有 odbc 支持的 erlang 24.1.2 雪花驱动程序 iODBC ODBC 管理器和 iODBC 管理器

下面是我的odbc安装配置

    ➜  sandbox odbcinst -j

2: SQLDriverConnect = [iODBC][Driver Manager]Specified driver could not be loaded (0) SQLSTATE=IM003

我可以通过 isql 连接，iodbctest 失败，我的简单测试用例失败：

defmodule Sandbox.OdbcTest do
use Sandbox.OdbcCase


test "test odbc" do
    conn_str = 'dsn=SnowflakeDSII'
    IO.inspect :odbc.connect(conn_str, [])
end
end

我尝试连接字符串为： conn_str = 'driver=/opt/snowflake/snowflakeodbc/lib/universal/libSnowflake.dylib;server=<SERVER>;uid=<USERNAME>;pwd=<PASSWORD>;role=<ROLE>;warehouse=TEST_WH;'

➜  sandbox mix test test/odbc_test.exs

恐怕来自 iodbstest 的消息解释了一切，但我希望有解决方案。 我关注了这些文章： https://docs.snowflake.com/en/user-guide/odbc-mac.html

https://community.snowflake.com/s/article/How-to-create-Snowflake-ODBC-DSN-On-MacOS

How do I install the ODBC driver for Snowflake successfully on an M1 Apple Silicon Mac?

【参考方案1】：

Snowflake 提供的 ODBC 驱动程序尚不支持 M1 的 ARM 处理器。

【讨论】：

谢谢，你知道我在哪里可以查看未来支持它的计划吗？

我也想知道是否/何时支持 arm64 @Srinath-menon
