I am trying to link to a VISA library (VISA is used to control data acquisition instruments), visa32.lib compiled for Windows. The library is shipped with Tektronix software.

I'm surprised loading it works. That sounds like a static library.

Using `nm' I did find: 00000000 I __imp__viOpenDefaultRM@4 00000000 T _viOpenDefaultRM@4

This looks like the stdcall calling convention. (See "Name-decoration convention" in <http://msdn.microsoft.com/en-us/library/zxk0tw93(v=vs.71).aspx>.) Passing ":convention :stdcall" to DEFCFUN should work. Cheers, -- Luís Oliveira http://kerno.org/~luis/
