[Rd] problems with iconv

[RogerP]

For some reason when I click on reply and sign-in  - the message I'm replying
to is not carried forward.  As you requested that include your message I
copied and pasted it from my email.

The location isn't mentioned in Appendix A, which you cite a portion 
of above, but it is mentioned in Solaris section of Appendix C, which 
you cite below.

This seems to indicate GNU libiconv should be installed in /usr/local, 
which is the location specified in the libiconv installation 
instructions: 

As usual for GNU packages: 
$ ./configure --prefix=/usr/local 
$ make 
$ make install 

Did you try the suggestion two paragraphs above this in Appendix C? 
"Some people have reported that the Solaris libintl needs to be 
avoided, for example by using --disable-nls or --with-included-gettext 
or using libintl from OpenCSW." 

As it turns out I put iconv and libiconv.so and libiconv.so.2.5.1 in
/usr/local/bin and /usr/local/lib.  Just for grins I copied these files to
/usr/local and tried again with the same results.  

This is my configure statement:

./configure --with-blas=-library=sunperf --with-lapack --with-readline=no
--x-includes=/usr/X11/include --x-libraries=/usr/X11/lib --prefix=/usr/local
--disable-nls  --with-included-gettext 

So, yes, I did try the suggestions mentioned in Appendix C.

Did you take the steps required to resolve the circular dependency 
between libiconv and gettext? 

I used the --disable-nls  and --with-included-gettext options.  I also
downloaded the more up-to-date cairo package.  

BTW, is there a program I can run to test my iconv binary?  I think that
would rule out any problem with the compilation.

Thanks for you suggestions and for any future help.  This is frustrating
because I have compiled R, just not with a workable iconv, which prevents me
from updating and adding packages.

Roger
