Convert 32-bit compiled open source libraries to 64-bit compiled libraries

Question

In my project, I am having set of open source libraries that are 32-bit compiled . How to compile those libraries in a such a way that the libraries should be 64-bit compatible ? How to make 64-bit compilation for those open source libraries?

Answer 1

There is no direct way to convert library 32 bit to 64 bit.

Please do follow step to resolve this issue.

1. You can find your open source library compatible with 64 bit on Web.
2. If didn't find library on web then you can build your lib with valid architecture with 64 bit. For the same set Library Target -> Build Setting -> Architecture.
