I see this error, too, when using cross-emerge. I did, in my first attempt at cross compilation: crossdev -t mipsel-linux-uclibc mipsel-linux-uclibc-fix-root mipsel-linux-uclibc Then, trying: mipsel-linux-uclibc-emerge -avuDN gcc I get: * ERROR: sys-libs/zlib-1.2.5-r2 failed (install phase): * unable to read SONAME from libz.so ``Azdo''s message in http://forums.gentoo.org/viewtopic-t-825260-start-0.html mentions that libz.so is created without soname; the creating command in my case is: mipsel-linux-uclibc-gcc -shared -Os -pipe -fomit-frame-pointer -I/usr/mipsel-linux-uclibc/usr/include/ -I/usr/mipsel-linux-uclibc/include/ -fPIC -D_LARGEFILE64_SOURCE=1 -o libz.so.1.2.5 adler32.lo compress.lo crc32.lo deflate.lo gzclose.lo gzlib.lo gzread.lo gzwrite.lo infback.lo inffast.lo inflate.lo inftrees.lo trees.lo uncompr.lo zutil.lo -lc -L/usr/mipsel-linux-uclibc/lib -L/usr/mipsel-linux-uclibc/usr/lib This is on x86_64 running 2.6.37-gentoo-r4.
Any updates on this bug? When doing cross build with i486 to i686 CHOST change with current zlib's configure script, getting soname failure export CHOST=i486-pc-linux-gnu echo "${CHOST}" | sed -e 's/^[^-]*-\([^-]*\)$/\1/' -e 's/^[^-]*-[^-]*-\([ ^-]*\)$/\1/' -e 's/^[^-]*-[^-]*-\([^-]*\)-.*$/\1/' linux looks correct but failure.
supposedly fixed with zlib-1.2.6 and above, at least i can do a cross-chost builds now
should be all set now in the tree; thanks for the report! Commit message: Extract host os field via config.sub http://sources.gentoo.org/sys-libs/zlib/zlib-1.2.7.ebuild?r1=1.3&r2=1.4
