This might be a problem with C++ name mangling ... try putting extern &quot;C&quot; {} around the include.

Most likely the compiler would have complained but thank you nevertheless for reading thoroughly ;-)<br />

Note the types were a guess only. I actually don't know the rules of name mangling and it differs between compilers.<br />

Hi,<br />
<br />
I am getting this error when I try to run my application.<br />
relocation error: test: symbol _Z17DBReadLicenseFilePKcP1<wbr />0a_db_parm<wbr />s, version dbsrv_r.so not defined in file dbsrv_r.so with link time reference<br />
<br />
What does this relocation error mean? How can I fix this?<br />
<br />
Thanks<br />

Hi,

I am getting this error when I try to run my application.
relocation error: test: symbol _Z17DBReadLicenseFilePKcP10a_db_parms, version dbsrv_r.so not defined in file dbsrv_r.so with link time reference

What does this relocation error mean? How can I fix this?

Thanks

What does relocation error with link time reference mean?

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
