SWIG致命错误C1083：无法打开包含文件

Question

I am trying to build python scripts from C++ code using SWIG and I am receiving the error in the title. If I change the interface and fully qualify the path to the external header file it works fine.

Couple of questions:

1. Can the path get included in the command call? I tried -IC:\\Code\\ExternalHeaders but that did not work.

2. Can this path be argument driven? Different developers will have different paths. This way they can make the path change in their project.scons file and everything would work.

We use SCONS for building all source code. The header file is located in C:\\Code\\Edwards\\EWCppLibrary\\EWBase . Here's the log:

Answer 1

You need to specify:

/IC:\Code\Edwards\EWCppLibrary\EWBase

For your compiler.
