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.
