Question

I am using RHEL 6 and trying to compile some code using SWIG.

The SWIG file is named mySwig.i and looks like

   %module base_module
   %{
     #include "base.h"
   %}
   %include "base.h"

The mySwig.i file is kept in a folder named foo. The folder foo also has other .h, .c and .cxx files.

The command I use is

    gcc -fpic -c foo/*

The output is:

    foo/mySwig.i:1 error: expected identifier or '(' before '%' token
    foo/mySwig.i:3 error: stray '#' in program
    foo/mySwig.i:5 error: expected identifier or '(' before '%' token

Does anyone have any ideas how to resolve these errors?

Answer 1

gcc -fpic -c foo/* will match all files in the directory foo/. You only want to match C files most likely. You can do what with gcc -fpic -c foo/*.c if you really want.

Personally I’d recommend using something like CMake or Autotools, or even just a Makefile to build your project rather than calling cc directly.
