I found including C++ support made building the cross compilers way more trouble and for many platforms I gave up trying to solve all the attendant problems.

If you want your binary to run on Solaris 2.9 you can't link with a libc from e.g. 2.11. Newer libc symbols will get referenced in your app that won't resolve on an older libc. > I have > to leave for the day now, but wondering if the cause of this libc.so > link problem is immediately obvious to anyone? ... > Here is the tail of the build log: > > /mnt/build/xgcc-4.1-build/sparc-sun-solaris2.9/gcc/./gcc/xgcc > -B/mnt/build/xgcc-4.1-build/sparc-sun-solaris2.9/gcc/./gcc/ > -B/mnt/build/xgcc-4.1/sparc-sun-solaris2.9/sparc-sun-solaris2.9/bin/ > -B/mnt/build/xgcc-4.1/sparc-sun-solaris2.9/sparc-sun-solaris2.9/lib/ ... > -Wl,--soname=libgcc_s.so.1 -Wl,--version-script=libgcc/./libgcc.map -o > ./libgcc_s.so.1.tmp libgcc/./_muldi3_s.o libgcc/./_negdi2_s.o ... > /mnt/build/xgcc-4.1/sparc-sun-solaris2.9/bin/sparc-sun-solaris2.9-ld: > skipping incompatible /usr/lib/libc.so when searching for -lc > /mnt/build/xgcc-4.1/sparc-sun-solaris2.9/bin/sparc-sun-solaris2.9-ld: > cannot find -lc Following the notes I had, you should have a solaris 2.9 libc under /mnt/build/xgcc-4.1/sparc-sun-solaris2.9/sparc-sun-solaris2.9/usr/lib/ E.g. on my system: > $ ls -l /xgcc-4.1/sparc-sun-solaris2.8/sparc-sun-solaris2.8/usr/lib/libc.* > -rw-r--r-- 1 nathan staff 1788084 Dec 9 2002 libc.a > lrwxrwxrwx 1 nathan staff 11 Oct 5 2006 libc.so -> ./libc.so.1 > -rwxr-xr-x 1 nathan staff 1157888 Dec 9 2002 libc.so.1 Questions to ask yourself: 1. Do you have the proper libc in that location? 2. Does your build try looking in that location? (e.g. use 'truss' to find out what which libc.so files sparc-sun-solaris2.9-ld tries to open). -Nathan -- For unsubscribe information see http://sourceware.org/lists.html#faq
