Hi, for info, we can't compile the factor vm with the default compiler (gcc 4.7.2) of debian oldstable wheezy anymore.
First, it has a false compilation error ( https://gcc.gnu.org/bugzilla/show_bug.cgi?id=54277): g++ -c -x c++-header -Wall -DFACTOR_VERSION="0.98" -DFACTOR_GIT_LABEL="heads/master-5ba44b37bc82bfdea706c16f33b3bbc13b9ca87c" -fomit-frame-pointer -Wl,--no-as-needed -m32 -O3 -g -std=c++11 -o vm/master.hpp.gch vm/master.hpp In file included from vm/master.hpp:112:0: vm/free_list_allocator.hpp: In lambda function: vm/free_list_allocator.hpp:137:35: error: no matching function for call to ‘factor::mark_bits::marked_p(factor::cell&) const’ vm/free_list_allocator.hpp:137:35: note: candidate is: In file included from vm/master.hpp:109:0: vm/mark_bits.hpp:81:8: note: bool factor::mark_bits::marked_p(factor::cell) <near match> vm/mark_bits.hpp:81:8: note: no known conversion for implicit ‘this’ parameter from ‘const factor::mark_bits*’ to ‘factor::mark_bits*’ The following patch workarounds error: diff --git a/vm/free_list_allocator.hpp b/vm/free_list_allocator.hpp index 65e6851..461004c 100644 --- a/vm/free_list_allocator.hpp +++ b/vm/free_list_allocator.hpp @@ -137 +137 @@ void free_list_allocator<Block>::compact(Iterator& iter, Fixup fixup, - if (!state.marked_p(block_addr)) + if (!this->state.marked_p(block_addr)) Even with the workaround, when then have g++ -c -Wall -DFACTOR_VERSION="0.98" -DFACTOR_GIT_LABEL="heads/master-5ba44b37bc82bfdea706c16f33b3bbc13b9ca87c" -fomit-frame-pointer -Wl,--no-as-needed -m32 -O3 -g -std=c++11 -o vm/compaction.o vm/compaction.cpp vm/compaction.cpp: In lambda function: vm/compaction.cpp:165:1: internal compiler error: in get_expr_operands, at tree-ssa-operands.c:1035 Please submit a full bug report, with preprocessed source if appropriate.
