hope this fix your issue Define log as a global variable, and declare it as external symbol by extern FILE *log; in other places that you use it.

Hope that helps I'd share the Properties files as well, it generally being a good idea to share and version all files that are needed to compile the project regardless of the IDE. Since it's an IDE tool that generates those files, I'd consider it bad form to leave them out, in case you want to set up a Continuous Integration server or something of that sort.
The *.suo files are Solution User Options, which kind of implies that they're per-user, not per-project. Same goes for the *.user files.

fixed the issue. Will look into that further You're breaking your abstraction by needing to know the definition of struct foo_struct outside of foo.c. The whole point of making a struct definition "private" to a particular source file is so that other source files aren't aware of and cannot manipulate the members of struct foo_struct directly.
You either need to move bar into foo.c, or you need to put the struct definition in foo.h (making it public), or you need to define an interface that allows other translation units to allocate, set, read, and deallocate items of type foo_s without exposing the details of its type, similar to how the routines in stdio.h manipulate objects of type FILE, something like
code :
foo_s *create_foo(int a, int b);
void set_foo(foo_s *f, char *property, int value);
int get_foo(foo_s *f, char *property);
void destroy_foo(foo_s **f);  // sets f to NULL after deallocation.
void blah(void)
{
  foo_s *f = create_foo(0,0);
  if (f)
  {
    set_foo(f, "a", 1);
    set_foo(f, "b", 2);

    printf("a = %d, b = %d\n", get_foo(f, "a"), get_foo(f, "b");
    destroy_foo(&f);
    assert(f == NULL);
  }
}

fixed the issue. Will look into that further Use Source Control System's File Sharing Feature
Pro: Fast and easy to set up, if the SCM system supports it. Pro/Con: Each consumer project can independently affect compile-time. Con: There is no official location, in the local working copy of sources. This can lead to confusion. Con: Source changes are not reflected in other locations until checkin and re-retrieve. To properly verify other projects, before checkin, is possible but a royal pain in the butt. Con: Not all SCM systems support shared files. Subversion’s closest feature is folder-level svn:externals.

Hope that helps Using extern is only of relevance when the program you're building consists of multiple source files linked together, where some of the variables defined, for example, in source file file1.c need to be referenced in other source files, such as file2.c.
It is important to understand the difference between defining a variable and declaring a variable:

wish of those help The new solution for code sharing is Git, there are some different services for that.
There is GitHub, where you can post source code for free, but it's open to public. If you wish to make it private, you must pay.
