compiling zsh 3.10 on Solaris 2.4 for dynamically loaded modules

[arif@xxxxxxxxxxxxxxxxx (Anthony Iano-Fletcher)]

Hi
	Im trying to compile zsh 3.1.0 with dynamically loaded binary
modules (a wonderful idea) for Solaris 2.4. Has anyone got this to work
and is it meant to work on Solaris yet?

I use

	./configure --enable-dynamic
 
and I get the following edited results...

	....
	checking for dlopen... yes
	checking for dlerror... yes
	checking for dlsym... yes
	checking for dlclose... yes
	....
	checking if your dlsym() needs a leading underscore... failed

This failure, I guess, turns off the dynamic option and I get a non-dynamic
zsh. When I try to lie and build a zsh with dynamic loading then it
will read the zle.so library but fail soon after.

Here is the output of truss......
 
open("/tmp/lib/zsh/3.1.0/zle", O_RDONLY)	= 3
fstat(3, 0xDFFFEF4C)				= 0
mmap(0x00000000, 4096, PROT_READ|PROT_EXEC, MAP_SHARED, 3, 0) = 0xDF7B0000

munmap(0xDF580000, 239338)			= 0
close(4)					= 0
munmap(0xDF7B0000, 4096)			= 0
zsh: failed to load module: zle
write(2, " z s h :   f a i l e d  ".., 32)	= 32
getuid()					= 11916 [11916]
argo% write(2, " a r g o %  ", 6)			= 6
read(0, 0xDF6C432C, 1024)			= 0
time()						= 854386460
getpid()					= 1133 [1132]
lseek(0, 0, SEEK_CUR)				= 768892
_exit(0)


Any suggestions? All this was done with a minimal environment in case it
made a difference but it didn't.

			thanks in advance,

				Anthony.
