Thanks for the feedback and suggestions.
You can't mount everywhere you might want to use a symlink.
I have a number of topic and src directories cross-linked for convenience.
I should be able to cd src and run cygport without issues.
[Cygwin directory symlinks have a quirk I don't remember working on any Unix I
tried: after cd src, I can operate on ../tgt where tgt may be a physical sibling
entry in the same directory as src, so is not limited to be an entry in the
logical directory ../ containing the symlink to src.]
My working kludge was:
/usr/share/cygport/lib/src_postinst.cygpart:1295ff:
origdlname=${dlname}
while [ $(readlink -f ${ltlibdir}/${dlname%/bin/*}) !=
$(readlink -f ${D}$(__host_prefix)) ]
do
dlname=../${dlname}
done
but it would have lower overhead as:
origdlname=${dlname}
# do full symlink resolution on both paths compared to avoid issues
local dest_prefix=$(readlink -f ${D}$(__host_prefix))
while [ $(readlink -f ${ltlibdir}/${dlname%/bin/*}) != $dest_prefix ]
do
dlname=../${dlname}
done
I now think curl would be the best template for this package, as it includes
exe, lib, devel, and doc subpackages.
