The salient parts of my post if I may repeat them here are :- For a fix I I tried the following to no avail:- --A) Looked through the README.builds.html ( http://hg.openjdk.java.net/jdk7/build/raw-file/tip/README-builds.html ) and found no obvoious settings for forcing the build program to see /usr/lib/libiconv. --B) set the envronmental variable LDFLAGS="-L/usr/lib" --C) made a wild guess and set the environmental variable LIBS="liconv" --D) tried setting LD_LIBRARY_PATH=/usr/lib:${LD_LIBRARY_PATH} which resulted in complaints that it should be unset Please note the sequence I reported, I tried builds with and without LDFLAGS set (and with and without a guess variable called LIBS="-liconv" SO libiconv need NOT be called. therefore the presence of libiconv.so on the system need not be called for any linking if it NOT needed > options are needed, e.g. I have never had to use -liconv on the link line > for the npt library we create in the jdk.

This is blfs linux built by compiling sources from scratch. I use pue64-bit i.e. non-multilib builds. I think you will find the Redhat/Fedora builds are multilib. So far my experience of {C}BLFS thousands of source files have been compiled successfully using make, cmake, ant, jam, boost-jam, scons etc. here is a link to the building of icedTea for instance ( http://www.linuxfromscratch.org/blfs/view/svn/general/icedtea6.html ) Amd here is a link to the ageing cblfs build of openjdk http://cblfs.cross-lfs.org/index.php/OpenJDK I think iconv is part of glibc ( http://www.gnu.org/s/hello/manual/libc/glibc-iconv-Implementation.html ) but some programs seem to require the installation of separate installation of libiconv. > What I suspect is that someone has corralled the iconv*() functions into > it's own library and now you not only need to include iconv.h, but you > need to link with -liconv on this system.
