[Ecls-list] fatal: relocation errors on Solaris x86 and OpenSolaris 64-bit.

[Dr. David Kirkby]

Hi,
Several months ago I discovered that Maxima would not build in Sage on 64-bit 
OpenSolaris. ECL built, but Maxima would not.

The error was:

make[3]: Entering directory 
`/export/home/drkirkby/sage-4.4.2/spkg/build/maxima-5.20.1.p0/src/src'
test -d binary-ecl || mkdir binary-ecl
ecl -norc -eval '(progn (load "../lisp-utils/defsystem.lisp") (funcall (intern 
(symbol-name :operate-on-system) :mk) "maxima" :compile :verbose t) 
(build-maxima-lib))' -eval '(ext:quit)'
ld.so.1: ecl: fatal: relocation error: R_AMD64_PC32: file

At the time, I did not have a clue whether this was a Maxima, ECL or Sage issue, 
but now I believe it is an ECL issue, as the link-editor thinks the shared 
object contains text relocations.

There's a command given on this Sun blog, which will show libraries with this 
problem

After downloading the latest from your git repository about an hour ago, and 
building ECL, with


export CC="gcc -m64"
./configure
make

I see:

drkirkby at hawk:/tmp/ecl$ elfdump -d ./build/libecl.so |  fgrep TEXTREL
       [23]  TEXTREL           0
       [31]  FLAGS             0x4                 [ TEXTREL ]


which indicates a problem.

One obvious reason for this is if the code is not compiled as position 
independent code. Anohter is if the code contains assembly code which is not 
position indepedant, but I think I've disabled that when I tried again with

$ ./configure --with-dffi=no

I also tried setting

CC="gcc -m64 -fPIC"

but that did not help either.

Have you any clue how I might resolve this?
