Not sure to understand.
Do you mean that it exist object_ files that have both ELF32+64 signatures ?
And then only one file could be used in a multi-arch system ?
If so, I did not know that such object_ files exist.

Not sure of course.
I am only sure that I did install 2 days ago Linux ManJaro + enabled
multi-arch 64+32.
And running fpc32 on that 64 bit OS raise a error at linking because of
those 2 crti.o and crtn.o files.

Here also on Manjaro (Arch OS) the 32 bit crti.o and crtn.o are in
/usr/lib32 and do have a ELF signature of 32 bit.
And crti.o and crtn.o that are in /lib (smartlink to /usr/lib ) are clearly
64 bit (but maybe I miss something about ELF64+32)
Now only for the sport, I would like to understand why those
/usr/lib/crti.o+crtn.o (with 64 bit ELF sign) are used by fpc.
Take a look at fpc source t_linux.pas line 508 :
StartSection('INPUT(');
if linklibc and (libctype<>uclibc) then
begin
{ crti.o must come first }
if librarysearchpath.FindFile('crti.o',false,s) then // NOT GOOD,
WHY ?
AddFileName(s)
else
Message1(exec_w_init_file_not_found,'crti.o');
{ then the crtbegin* }
if cs_create_pic in current_settings.moduleswitches then
begin
if librarysearchpath.FindFile('crtbeginS.o',false,s) then //
HERE GOOD, LIKE ALL OTHERS
AddFileName(s)
else
Message1(exec_w_init_file_not_found,'crtbeginS.o');
end
else
....
Why librarysearchpath assign a ELF 64 to crti.o' (and ctri.o) but the good
ELF 32 to all others ?
Strange...
By the way, many thanks Seighard for your attention.
