Compilation Errors

A quick, unsorted list of compilation errors on SGI IRIX 6.5, along with fixes.

error: `sighandler_t’ undeclared (first use this function)

sighandler_t comes from Linux. It is defined as typedef void (*sighandler_t)(int); so you can copy this definition.

invalid conversion from unsigned int*' to socklen_t*'

E.g. happening during initializing argument 5 of int getsockopt(int, int, int, void*, socklen_t*).

Cast to proper type, (socklen_t*).

error: `textdomain’ undeclared (first use this function)

textdomain() is actually named libintl_textdomain(), and for that you need to include libintl.h and link with -lintl.

Also, *domain functions are supposedly NO-OPs so, alternatively, you can comment them from source.

A value of type “void *” cannot be used to initialize an entity of type “buffer_proc_t”.

No solution on record.

The expression must be a pointer to a complete object type.

This error may occur on lines such as data->data.ptr += length;.

Use this syntax:

-      data->data.ptr += length;
+      {
+        char* p = (char*)(data->data.ptr) + length;
+        data->data.ptr = p;
+      }

The source file “obstack.h” is unavailable.

That error may occur on lines such as #include <obstack.h>.

Find the header file location and provide it directly, using double quotes:

-#include <obstack.h>
+#include "getopt/obstack.h"

An entity with internal linkage cannot be referenced within an inline function with external linkage

You probably have the function declared as inline. You need to remove the inline.

Unresolved text symbol “strnlen” – 1st referenced by …

That error may happen in object files such as ../lib/libdpkg.a(tarfn.o).

Define strnlen directly in program source, like this:

size_t
strnlen(const char *s, size_t len)  {
  size_t l = 0;
  while(s[l] && l < len) l++;
  return l;
}

For MIPSPro Compiler >= 7.3
