I want to access via ruby ​​in 64 bit on the sybase-db (os is windows). And get the following error:

"Could not load SQLAnywhere DBCAPI library".

What can be the reason for this? The path details should fit.

Thanks and Greetings Pascal

do you have the 32 or 64-bit installation of SA?

here is a small copy-paste from

For Windows, make sure that the 64-bit or 32-bit DLLs (dbcapi.dll, dblib17.dll, dbicu17.dll, dbicudt17.dll, dblgen17.dll, dbextenv17.dll, and dbrsa17.dll) can be located. Check that the database server bin32 or bin64 folder is in your PATH.

it is an 64 bit installation, but with all the 32 bit items. the bin32 and the bin64 path is in the path-variable. i also do that:

irb(main):001:0> require 'sqlanywhere'
=> true
irb(main):002:0> api =
=> #<sqlanywhere::sqlanywhereinterface:0x00000002dc90b8>
irb(main):003:0> SQLAnywhere::API.sqlany_initialize_interface( api )
=> 0
irb(main):004:0> api.sqlany_init()

Any Idea???

As Vlad has asked: Are the mentioned DLLs like dbcapi.dll in the according %SQLANY17%\bin64 subdirectory?

(15 Aug '17, 03:08) Volker Barth

yes, they are there...

(15 Aug '17, 03:15) pmichel29021980

You said ... the bin32 and the bin64 path is in the path-variable ... which makes me think that you have these folders listed in that order (32-bit first, then 64-bit). Try listing them in the reverse order or, better yet, if you are using 64-bit software don't include the 32-bit folder in PATH.

Is there a particular reason the question is downvoted (twice)?

(16 Aug '17, 03:39) Volker Barth

Thank you Mr. Barth, this question is justified ...

A small update. If I use Ruby in version 2.3.3 as 64 bit, then everything works fine.

Here I use the "old" DevKit to build / install the GEM, and this seems to work.

With Ruby 2.4.1 in 64 bit and the supplied MySYS2 Toolkit there are seemingly problems to build / install the GEM error-free.

Many greetings, Pascal
