Install can't see libunistring

I'm trying to install guile 2.0 on a remote provider, i.e., a "home"
install. I did install the latest libunistring in my ~/opt , but guile
./configure --prefix=/my/home/opt/guile always complains

configure: error: GNU libunistring is required, please install it.

The ~/opt ~/opt/lib ~/opt/share ~/opt/include is on the PATH. Any ideas
what I'm doing wrong?

If you installed all the goodies under ~/opt why not install guile with —prefix=/my/home/opt ?

Like I said, it's not working. No combination works. Here's my PATH

> echo $PATH
/meta/b/borgauf/perl5/bin:/bin:/usr/bin:/usr/pkg/bin:/usr/local/bin:/meta/b/borgauf/opt:/meta/b/borgauf/opt/lib:/meta/b/borgauf/opt/include:/meta/b/borgauf/opt/share:/meta/b/borgauf/opt/emacs/bin

I've unpacked guile in ~/Downloads/guile-2.0.11/

I run

> ./configure --prefix=/meta/b/borgauf/opt

and get

configure: error: GNU libunistring is required, please install it.

The contents of ~/opt/lib are

libunistring.a  libunistring.la  libunistring.so  libunistring.so.2
 libunistring.so.2.0.0

The configure script is simply not seeing this -- or it needs something
else?

Can I simply do a home install on another machine and copy it over?

Since libunistring is not installed in one of the standard places, you
need to help 'configure' find it.

PATH is only used to find programs, not libraries or include files, so
it makes sense to add "$HOME/opt/bin" to PATH, but not the others.  Also
note that the character "~" is expanded by the shell only when found
unquoted at the beginning of a word, so it has no special meaning in
environment variables like PATH.  Such variables must contain absolute
directory names like "/home/borgauf/opt/bin".

Many libraries install *.pc files in <PREFIX>/lib/pkgconfig.  If you
have 'pkg-config', then the best approach to help 'configure' find those
libraries is to include <PREFIX>/lib/pkgconfig in PKG_CONFIG_PATH.

Unfortunately, libunistring does not install a *.pc file, so another
approach is needed there.  If you run "./configure --help", one of the
options is:

  --with-libunistring-prefix[=DIR]  search for libunistring in DIR/include and DIR/lib

There are similar options for libiconv, libltdl, libintl, and
libreadline, as well as environment variables to indicate the location
of libffi and bdw-gc.  I would use these options only in cases where the
'pkg-config' approach fails.

Please let us know how it goes!

    Regards,
      Mark

‘config.log’ has more details on what makes ‘configure’ think that
libunistring is unavailable.

HTH,
