+
+Hi,
+
+the code works only on Solaris based on OpenSolaris-ON from February 18 2010 or 
+later.
+
+Many people however still use Solaris 10.
+
+BTW: there is an official portable ELF way based on the AUX vector to do the same 
+but this was unfortunately not made a public libc interface, so it would need to 
+be incorporated into your code:
+
+https://sourceforge.net/p/schillix-on/schillix-on/ci/default/tree/usr/src/lib/libc/port/gen/getauxv.c
+
+___getauxptr(AT_PHDR)	returns the address of &phdr[0]
+___getauxval(AT_PHENT)	returns sizeof(phdr[0])
+___getauxval(AT_PHNUM)	returns # phdr entries
+
+
+Here is a patch to disable the non-portable code getting the code to compile at 
+all:
