I'm building gcc 4.4.0 on Solaris 9 on Sparc using gcc-3.4.6. The build is failing in the 3rd stage with the error constructors_destructor_fn_imps.hpp: No such file or directory The configuration was done using /path/to/src/gcc-4.4.0/src/configure --srcdir=/path/to/src/gcc-4.4.0/src --program-suffix=-4.4.0 --enable-languages='c,c++' Output from make is below. The build is failing at the third stage, so the 2nd stage went through okay. What am I doing wrong? Thanks for your help. # BEGIN make output fragment Making all in include make[4]: Entering directory `/big1/usr.local/src/gcc-4.4.0/sparc-sol9/sparc-sun-solaris2.9/libstdc++-v3/include' mkdir -p ./sparc-sun-solaris2.9/bits/extc++.h.gch /usr/local/src/gcc-4.4.0/sparc-sol9/./gcc/xgcc -shared-libgcc -B/usr/ local/src/gcc-4.4.0/sparc-sol9/./gcc -nostdinc++ -L/usr/local/src/ gcc-4.4.0/sparc-sol9/sparc-sun-solaris2.9/libstdc++-v3/src -L/usr/ local/src/gcc-4.4.0/sparc-sol9/sparc-sun-solaris2.9/libstdc++-v3/ src/.libs -B/usr/local/sparc-sun-solaris2.9/bin/ -B/usr/local/sparc- sun-solaris2.9/lib/ -isystem /usr/local/sparc-sun-solaris2.9/include - isystem /usr/local/sparc-sun-solaris2.9/sys-include -Winvalid-pch -x c+ -header -g -O2 -I/usr/local/src/gcc-4.4.0/sparc-sol9/sparc-sun- solaris2.9/libstdc+-v3/include/sparc-sun-solaris2.9 -I/usr/local/src/ gcc-4.4.0/sparc-sol9/sparc-sun-solaris2.9/libstdc++-v3/include -I/big2/ usr.local/src/gcc-4.4.0/src/libstdc++-v3/libsupc++ -O2 -g /big2/ usr.local/src/gcc-4.4.0/src/libstdc++-v3/include/precompiled/extc++.h - o sparc-sun-solaris2.9/bits/extc++.h.gch/O2g.gch In file included from /usr/local/src/gcc-4.4.0/sparc-sol9/sparc-sun- solaris2.9/libstdc++-v3/include/ext/pb_ds/detail/standard_policies.hpp: 45, from /usr/local/src/gcc-4.4.0/sparc-sol9/sparc-sun- solaris2.9/libstdc++-v3/include/ext/pb_ds/assoc_container.hpp:46, from /big2/usr.local/src/gcc-4.4.0/src/libstdc++-v3/ include/precompiled/extc++.h:58: /usr/local/src/gcc-4.4.0/sparc-sol9/sparc-sun-solaris2.9/libstdc++-v3/ include/ext/pb_ds/hash_policy.hpp:287:81: error: ext/pb_ds/detail/ resize_policy/hash_load_check_resize_trigger_imp.hpp: No such file or directory In file included from /usr/local/src/gcc-4.4.0/sparc-sol9/ sparc-sun-solaris2.9/libstdc++-v3/include/ext/pb_ds/detail/ rb_tree_map_/rb_tree_.hpp:48, from /usr/local/src/gcc-4.4.0/sparc-sol9/sparc-sun- solaris2.9/libstdc++-v3/include/ext/pb_ds/detail/ container_base_dispatch.hpp:55, from /usr/local/src/gcc-4.4.0/sparc-sol9/sparc-sun- solaris2.9/libstdc++-v3/include/ext/pb_ds/assoc_container.hpp:47, from /big2/usr.local/src/gcc-4.4.0/src/libstdc++-v3/ include/precompiled/extc++.h:58: /usr/local/src/gcc-4.4.0/sparc-sol9/sparc-sun-solaris2.9/libstdc++-v3/ include/ext/pb_ds/detail/bin_search_tree_/bin_search_tree_.hpp:467:81: error: ext/pb_ds/detail/bin_search_tree_/ constructors_destructor_fn_imps.hpp: No such file or directory make[4]: * [sparc-sun-solaris2.9/bits/extc++.h.gch/O2g.gch] Error 1 make[4]: Leaving directory `/big1/usr.local/src/gcc-4.4.0/sparc-sol9/ sparc-sun-solaris2.9/libstdc++-v3/include' make[3]: * [all-recursive] Error 1 make[3]: Leaving directory `/big1/usr.local/src/gcc-4.4.0/sparc-sol9/ sparc-sun-solaris2.9/libstdc++-v3' make[2]: * [all] Error 2 make[2]: Leaving directory `/big1/usr.local/src/gcc-4.4.0/sparc-sol9/ sparc-sun-solaris2.9/libstdc++-v3' make[1]: * [all-target-libstdc++-v3] Error 2 make[1]: Leaving directory `/big1/usr.local/src/gcc-4.4.0/sparc-sol9' make: * [all] Error 2 # END make output fragment
