I am using Debian gnu/Linux on an Athlon-mp (dual-core, k7) and used Aptitude and Apt-get to upgrade my software recently. This e-mail address is listed on the Aptitude screen as the "Maintainer" for "gcc-4.1" (when pre-compiled and downloaded with Aptitude). The "gcc -v" is: Target: i486-linux-gnu Configured with: ../src/configure -v --enable-languages=c,c++,fortran,objc,obj-c++,treelang --prefix=/usr --enable-shared --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --enable-nls --program-suffix=-4.1 --enable-__cxa_atexit --enable-clocale=gnu --enable-libstdcxx-debug --enable-mpfr --with-tune=i686 --enable-checking=release i4 86-linux-gnu Thread model: posix gcc version 4.1.2 20061115 (prerelease) (Debian 4.1.1-21) I am one of the people compiling and checking gcc-4_2-branch - I have compiled it many times but only recently with gcc-4.1 (obtained from you). When I try to compile gcc-4_2-branch (20070427) I run into trouble that seems to involve the ABI of the system used to compiled the version of the GCC toolchain that you released. The above "gcc -v" makes no mention of multilibs or -m64 but when I compile gcc-4_2-branch using your toolchain I run into trouble with it thinking that I want 64bit code. If I _DO_ ./configure gcc-4_2-branch with the parameter --enable-multilib then ./configure sets this in the makefile: "CFLAGS=-O2 -g -O2 -m64" . If I do _NOT_ use --enable-multilib then -m64 _still_ appears in some (but not all) the Makefiles. After configuring (with no attempt to use a 64 bit ABI) and then typing "make" the compile gets as far as through all three stages and into the first library (zlib) but then fails when it goes on to the next library (libstdc++-v3). Anyways, here is the make error that turns up, eventually. make[6]: Entering directory `/opt/gcc-4_2-build/i686-pc-linux-gnu/64/libstdc++-v3' make "AR_FLAGS=rc" "CC_FOR_BUILD=/usr/bin/gcc-4.1" "CC_FOR_TARGET=/opt/gcc-4_2-build/./gcc/xgcc -B/opt/gcc-4_2-build/./gcc/ -B/usr//bin/ -B/usr//lib/ -isystem /usr//include -isystem /usr//sys-include" "CFLAGS=-O2 -g -O2 -m64" "CXXFLAGS=-g -O2 -D_GNU_SOURCE -m64" "CFLAGS_FOR_BUILD=-g -O2" "CFLAGS_FOR_TARGET=-O2 -g -O2 " "INSTALL=/usr/bin/install -c" "INSTALL_DATA=/usr/bin/install -c -m 644" "INSTALL_PROGRAM=/usr/bin/install -c" "INSTALL_SCRIPT=/usr/bin/install -c" "LDFLAGS=-m64" "LIBCFLAGS=-O2 -g -O2 -m64" "LIBCFLAGS_FOR_TARGET=-O2 -g -O2 " "MAKE=make" "MAKEINFO=makeinfo --split-size=5000000 --split-size=5000000 " "PICFLAG=" "PICFLAG_FOR_TARGET=" "SHELL=/bin/sh" "RUNTESTFLAGS=" "exec_prefix=/usr" "infodir=/usr/share/info" "libdir=/usr/lib" "includedir=/usr/include" "prefix=/usr" "tooldir=/usr/" "gxx_include_dir=/usr/include/c++/4.2" "AR=ar" "AS=/opt/gcc-4_2-build/./gcc/as" "LD=/opt/gcc-4_2-build/./gcc/collect-ld" "RANLIB=ranlib" "NM=/opt/gcc-4_2-build/./gcc/nm" "NM_FOR_BUILD=" "NM_FOR_TARGET=nm" "DESTDIR=" "WERROR=" all-recursive make[7]: Entering directory `/opt/gcc-4_2-build/i686-pc-linux-gnu/64/libstdc++-v3' Making all in include make[8]: Entering directory `/opt/gcc-4_2-build/i686-pc-linux-gnu/64/libstdc++-v3/include' make[8]: Nothing to be done for `all'. make[8]: Leaving directory `/opt/gcc-4_2-build/i686-pc-linux-gnu/64/libstdc++-v3/include' Making all in libsupc++ make[8]: Entering directory `/opt/gcc-4_2-build/i686-pc-linux-gnu/64/libstdc++-v3/libsupc++' /bin/sh ../libtool --tag CXX --tag disable-shared --mode=compile /opt/gcc-4_2-build/./gcc/xgcc -shared-libgcc -B/opt/gcc-4_2-build/./gcc -nostdinc++ -L/opt/gcc-4_2-build/i686-pc-linux-gnu/64/libstdc++-v3/src -L/opt/gcc-4_2-build/i686-pc-linux-gnu/64/libstdc++-v3/src/.libs -B/usr//bin/ -B/usr//lib/ -isystem /usr//include -isystem /usr//sys-include -m64 -I/root/downloads/gcc-4_2-branch/libstdc++-v3/../gcc -I/opt/gcc-4_2-build/i686-pc-linux-gnu/64/libstdc++-v3/include/ -I/opt/gcc-4_2-build/i686-pc-linux-gnu/64/libstdc++-v3/include -I/root/downloads/gcc-4_2-branch/libstdc++-v3/libsupc++ -fno-implicit-templates -Wall -Wextra -Wwrite-strings -Wcast-qual -fdiagnostics-show-location=once -g -O2 -D_GNU_SOURCE -m64 -c -o del_op.lo /root/downloads/gcc-4_2-branch/libstdc++-v3/libsupc++/del_op.cc /opt/gcc-4_2-build/./gcc/xgcc -shared-libgcc -B/opt/gcc-4_2-build/./gcc -nostdinc++ -L/opt/gcc-4_2-build/i686-pc-linux-gnu/64/libstdc++-v3/src -L/opt/gcc-4_2-build/i686-pc-linux-gnu/64/libstdc++-v3/src/.libs -B/usr//bin/ -B/usr//lib/ -isystem /usr//include -isystem /usr//sys-include -m64 -I/root/downloads/gcc-4_2-branch/libstdc++-v3/../gcc -I/opt/gcc-4_2-build/i686-pc-linux-gnu/64/libstdc++-v3/include/ -I/opt/gcc-4_2-build/i686-pc-linux-gnu/64/libstdc++-v3/include -I/root/downloads/gcc-4_2-branch/libstdc++-v3/libsupc++ -fno-implicit-templates -Wall -Wextra -Wwrite-strings -Wcast-qual -fdiagnostics-show-location=once -g -O2 -D_GNU_SOURCE -m64 -c /root/downloads/gcc-4_2-branch/libstdc++-v3/libsupc++/del_op.cc -o del_op.o /root/downloads/gcc-4_2-branch/libstdc++-v3/libsupc++/del_op.cc:1: sorry, unimplemented: 64-bit mode not compiled in make[8]: *** [del_op.lo] Error 1 make[8]: Leaving directory `/opt/gcc-4_2-build/i686-pc-linux-gnu/64/libstdc++-v3/libsupc++' make[7]: *** [all-recursive] Error 1 make[7]: Leaving directory `/opt/gcc-4_2-build/i686-pc-linux-gnu/64/libstdc++-v3' make[6]: *** [all] Error 2 make[6]: Leaving directory `/opt/gcc-4_2-build/i686-pc-linux-gnu/64/libstdc++-v3' make[5]: *** [multi-do] Error 1 make[5]: Leaving directory `/opt/gcc-4_2-build/i686-pc-linux-gnu/libstdc++-v3' make[4]: *** [all-multi] Error 2 make[4]: Leaving directory `/opt/gcc-4_2-build/i686-pc-linux-gnu/libstdc++-v3' make[3]: *** [all-recursive] Error 1 make[3]: Leaving directory `/opt/gcc-4_2-build/i686-pc-linux-gnu/libstdc++-v3' make[2]: *** [all] Error 2 make[2]: Leaving directory `/opt/gcc-4_2-build/i686-pc-linux-gnu/libstdc++-v3' make[1]: *** [all-target-libstdc++-v3] Error 2 make[1]: Leaving directory `/opt/gcc-4_2-build' make: *** [all] Error 2
The ./configure script (of gcc-4_2-branch) seems to detect the ability to produce 64 bit code and throws some "-m64" 's into some of the Makefiles and a few of the created libtools. Hand editing the Makefiles to remove all "-m64" 's and then recompiling works for a while and then fails here: /usr/bin/gcc-4.1 -shared .libs/xmlj_dom.o .libs/xmlj_error.o .libs/xmlj_io.o .libs/xmlj_node.o .libs/xmlj_sax.o .libs/xmlj_transform.o .libs/xmlj_util.o .libs/xmlj_xpath.o ../../../native/jni/classpath/.libs/jcl.o /usr/lib/libxslt.so -L/usr/lib /usr/lib/libxml2.so -Wl,-soname -Wl,libxmlj.so.0 -o .libs/libxmlj.so.0.0.0 /usr/bin/ld: warning: i386:x86-64 architecture of input file `.libs/xmlj_dom.o' is incompatible with i386 output /usr/bin/ld: warning: i386:x86-64 architecture of input file `.libs/xmlj_error.o' is incompatible with i386 output /usr/bin/ld: warning: i386:x86-64 architecture of input file `.libs/xmlj_io.o' is incompatible with i386 output /usr/bin/ld: warning: i386:x86-64 architecture of input file `.libs/xmlj_node.o' is incompatible with i386 output /usr/bin/ld: warning: i386:x86-64 architecture of input file `.libs/xmlj_sax.o' is incompatible with i386 output /usr/bin/ld: warning: i386:x86-64 architecture of input file `.libs/xmlj_transform.o' is incompatible with i386 output /usr/bin/ld: warning: i386:x86-64 architecture of input file `.libs/xmlj_util.o' is incompatible with i386 output /usr/bin/ld: warning: i386:x86-64 architecture of input file `.libs/xmlj_xpath.o' is incompatible with i386 output /usr/bin/ld: warning: i386:x86-64 architecture of input file `../../../native/jni/classpath/.libs/jcl.o' is incompatible with i386 output I have had NO trouble compiling gcc-4_2-branch (on Debian Linux) with gcc versions: gcc version 3.3.5 (Debian 1:3.3.5-13) gcc version 3.4.4 20050314 (prerelease) (Debian 3.4.3-13sarge1) gcc version 3.4.2 (mingw-special) - /usr/bin/i586-mingw32msvc-gcc gcc version 4.2.0 20070413 (prerelease) I have had NO trouble compiling gcc-4_2-branch (on WinXP Cygwin) with gcc versions: gcc version 4.1.1 (release) gcc version 4.2.0 20061225 (prerelease) I can even compile gcc-4_2-branch (newest version) with one of the above working compilers and install it as the main system compiler; then use that to compile gcc-4_2-branch without any problems. What I am unable to do is get the version that you released (4.1.2) to work. I do understand that it is a pre-release but I believe that an "official" 4.1.2 is avaiable (don't know if it shares the -m64 bug). Most people who apt-get from the _http://ftp.us.debian.org/debian/dists/ ? /main/binary-i386/_ (http://ftp.us.debian.org/debian/dists/ ? /main/binary-i386/) directory would NOT want -m64 UNLESS they specifically asked for it on the command line. If the people who created the binaries configured on an Opteron (K8) then they might have inadvertantly allowed a default setting to be used by NOT specifically requesting a -m32 ABI. You might consider an "official" version of 4.1.2 (from gnu.org) for your archives at _ftp.us.debian.org_ (ftp://ftp.us.debian.org) (and mirrors). If you _do_ like a pre-release version then your might want to whip up a 4.2.0 from the SVN (it really works quite well). Please check / fix the version on your archive. I am going to remove it from my HD and apt-get a new compiled version from elsewhere. Thanks, Rob -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
