linux - Compilng libgcc xgcc error -


i'm trying install cross compiler, this tutorial, , when want make libgcc put make all-target-libgcc in terminal. make throws error

checking whether ln -s works... yes checking i586-elf-gcc...  /usr/src/build-gcc/./gcc/xgcc -b/usr/src/build-gcc/./gcc/         -b/usr/local/cross/i586-elf/bin/ -b/usr/local/cross/i586-elf/lib/ -isystem /usr/local/cross/i586-elf/include -isystem /usr/local/cross/i586-elf/sys-include    checking suffix of object files... configure: error: in `/usr/src/build-gcc/i586-elf/libgcc': configure: error: cannot compute suffix of object files: cannot compile see `config.log' more details. make: *** [configure-target-libgcc] error 1

in config.log found

in fact xgcc don't have '-v' option. i'm searching way how compile libgcc.

thanks in advance

here's problem: before attempted build libgcc described, built extreme bare-bones cross compiler. now, part of standard tests configure script runs test compiler see if produce working executable file under normal conditions. bare bones compiler can't. fortunately, libgcc, don't need produce executable, static library libgcc.a . problem stupid gnu autoconf-generated script doesn't realize that.

i encountered same problem , devised ugly workaround. need comment out section of libgcc/configure file in gcc source directory. here's section commented out version; similar yours:

at line 3484:

{ $as_echo "$as_me:${as_lineno-$lineno}: result: $ac_file" >&5 $as_echo "$ac_file" >&6; } # begin phillip edit # if test -z "$ac_file"; :   # $as_echo "$as_me: failed program was:" >&5 # sed 's/^/| /' conftest.$ac_ext >&5  # { { $as_echo "$as_me:${as_lineno-$lineno}: error: in \`$ac_pwd':" >&5 # $as_echo "$as_me: error: in \`$ac_pwd':" >&2;} # { as_fn_set_status 77 # as_fn_error "c compiler cannot create executables # see \`config.log' more details." "$lineno" 5; }; } # fi ac_file='a.out' # end phillip edit ac_exeext=$ac_cv_exeext

hope helps.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
