The next library build is libjava. > > 1): Then it goes back after configuring classpath and _rebuilds_ zlib > again. After re-doing zlib it continues with the rest of libjava. > > It is too bad it can't build it satisfactory for libjava the first time. > > > 2): Another issue is I see this warning: > > # grep -B 2 -A 2 --color=always configure:\ WARNING: > /opt/gcc-4_3-build/make_9_log.txt > no > checking whether Solaris gcc optimization fix is necessary... no > configure: WARNING: "Must define GC_DEBUG and use debug alloc. in clients." > configure: WARNING: "Client must not use -fomit-frame-pointer." > updating cache ./config.cache > configure: creating ./config.status > > > Why take an action to trigger the warning, apparently we should define > GC_DEBUG > and not use -fomit-frame-pointer so lets refrain from creating the Makefile > that way. > > > # gcc/xgcc -v > Using built-in specs. > Target: i686-pc-linux-gnu > Configured with: /root/downloads/gcc-4_3-trunk/configure --verbose > --enable-languages=c,ada,c++,fortran,java,objc,obj-c++ --with-tune=athlon-xp > --prefix=/usr --enable-objc-gc --enable-concept-checks --disable-multilib > --with-gxx-include-dir=/usr/include/c++/4.3 --enable-libstdcxx-debug > --enable-static --enable-shared --enable-initfini-array > --enable-__cxa_atexit --enable-threads=posix > --enable-version-specific-runtime-libs --enable-libssp --enable-libmudflap > --enable-libgomp --disable-werror --enable-nls --with-included-gettext > --enable-decimal-float --with-long-double-128 --enable-debug > --enable-java-gc=boehm --with-x --x-includes=/usr/X11R6/include > --x-libraries=/usr/X11R6/lib --enable-java-awt=gtk,xlib --enable-gtk-cairo > --enable-qt-peer --enable-xmlj --enable-gconf-peer --enable-tool-wrappers > --enable-portable-native-sync --enable-examples --enable-libgcj-multifile > --with-stabs --enable-hash-synchronization --enable-gc-debug > --enable-interpreter --with-system-zlib --enable-libada --with-tls > --with-cpu=athlon-xp --with-arch=athlon-xp > --enable-stage1-checking=assert,gc,misc,rtl,rtlflag,runtime,tree > Thread model: posix > gcc version 4.3.0 20070601 (experimental) As far as 1 goes, libjava has been removed so that part is no longer relevant. For 2, which configure script prints that warning?
