configure.in:966 is the AC_OUTPUT(...) line, so would you send the output of "autoconf --version" too please?
There are three versions floating around: 2.13, 2.50 and 2.61 and with various combinations of packages "autoconf" and "autoconf2.13" installed in differnt orders I have seen all three version numbers emitted. However, all versions seem to work with xaos. A secondary issue is that here, with any version of autoconf, the same part of the output goes: dh_testdir ln -sf /usr/share/misc/config.sub ln -sf /usr/share/misc/config.guess autoconf CFLAGS=-g ./configure --prefix=/usr checking build system type... armv5tel-unknown-linux-gnueabi checking host system type... armv5tel-unknown-linux-gnueabi ... gcc -g -I/usr/include -fomit-frame-pointer -DSFFE_USING -DSFFE_CMPLX_GSL -I/home/martin/arm/xaos-3.3/src/include -c -o xldio.o xldio.c ... It looks like the build script is overriding CFLAGS, so this method will not give you a VFP-enabled binary anyway. In fact Debian is not even optimising the compilation of xaos on any architecture. As far as I know there is no single way to set CFLAGS (and CXXFLAGS where appropriate) in debian package builds. It may work for some packages, but you will have to hack debian/rules or other files for others, or play some trick like providing a fake gcc script that inserts extra options on the command line and calls the real compiler, like removing /usr/bin/gcc and replacing it with: #! /bin/sh exec /usr/bin/gcc-4.3 -mfpu=vfp -mfloat-abi=softfp "$@" where the magic 4 characters "$@" pass on all supplied arguments preserving spacing and quotation, with a similar trick for for /usr/bin/g++ M -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
