Hello,
Here:http://www.mail-archive.com/[email protected]/msg06933.html
I found that rdynamic is used by linux and -Wl,--export-dynamic by Sun Solaris.
You need to adapt your sripts or makefile.
But when I replace LDFLAGS = -rdynamic
by
LDFLAGS = -Wl,--export-dynamic
in the file Makefile.config
(I use :
ld: Software Generation Utilities - Solaris Link Editors: 5.8-1.284
on Sun Solaris 8 Sparc)
I have this error:

Can you adapt your scripts or Makefile to use it on Sun Solaris 8 system ?
Thanks in advance.

I think you can ignore this error message. An elinks executable
was still generated, wasn't it? Make didn't say that the
compiler returned an error.
Pasky added the -rdynamic option to LDFLAGS in commit
450ac0056a84d75a54675a98e7eb898599b9389a:
| Use -rdynamic when available. It makes backtrace work right and
| it will be a must when dynamic .so modules will be introduced
| (not that it would be anytime soon). Looks like zero or only very
| minimal overhead.
If I understand correctly, "dynamic .so modules" refers to
dynamic loading of ELinks-specific plugins that could then call
functions defined in the elinks executable. This has apparently
not been implemented; at least I cannot find any dlsym() calls.
And if the backtrace doesn't work right, that isn't fatal.
Two things could be done:
1. Fix the check in the configure scrip t, so that it detects if
the compiler does not support -rdynamic, even if the compiler
does not return an error. There is a FIXME about this.
2. On systems that do not support -rdynamic, make the scrip t
choose some other option that has a similar effect.
Which linker are you using on Solaris 8?
Does it support any such option?
How can the scrip t detect which option should be used?
