Date.today problem on linux with Ruby 1.8.6
in [Ruby]

From: Jarmo Pertman on 29 May 2010 20:34 i executed make test and it seems that some of the tests are also failing: jarmo(a)jarmo-laptop:~/Downloads/ruby-1.8.6-p399$ make test not ok float 1 -- ./sample/test.rb:1172 not ok float 2 -- ./sample/test.rb:1173 not ok float 3 -- ./sample/test.rb:1174 not ok float 4 -- ./sample/test.rb:1175 not ok float 5 -- ./sample/test.rb:1176 not ok float 6 -- ./sample/test.rb:1177 not ok float 7 -- ./sample/test.rb:1178 not ok float 8 -- ./sample/test.rb:1179 not ok float 9 -- ./sample/test.rb:1180 test failed make: *** [test] Error 1 # test.rb 1172 test_ok(2.6.floor == 2) 1173 test_ok((-2.6).floor == -3) 1174 test_ok(2.6.ceil == 3) 1175 test_ok((-2.6).ceil == -2) 1176 test_ok(2.6.truncate == 2) 1177 test_ok((-2.6).truncate == -2) 1178 test_ok(2.6.round == 3) 1179 test_ok((-2.4).truncate == -2) 1180 test_ok((13.4 % 1 - 0.4).abs < 0.0001) Is there any special switches or commands i should use while compiling?

You could also check [1] to see whether it's a known bug already.

As far as I checked, ruby_strtod() in util.c is broken by gcc 4.4's optimization. 1. disable optimization. ./configure make vi Makefile # replace -O2 to -O0. touch util.c # update the timestamp to recompile util.c. make sudo make install 2. use gcc-4.3. sudo apt-get install gcc-4.3 ./configure CC=gcc-4.3 make sudo make install 3. configure with -fno-strict-aliasing and --enable-pthread. (I don't know why it dismisses the problem...) ./configure CFLAGS='-g -O2 -fno-strict-aliasing' --enable-pthread make sudo make install
From: Jarmo Pertman on 30 May 2010 09:07 By the way, doing every same move with 1.8.7 as i did with 1.8.6 works indeed: jarmo(a)jarmo-laptop:~/Downloads/ruby-1.8.7-p249$ ruby -v ruby 1.8.7 (2010-01-10 patchlevel 249) [i686-linux] jarmo(a)jarmo-laptop:~/Downloads/ruby-1.8.7-p249$ ruby -e "require 'date'; puts Date.today" 2010-05-30 But my problem was that i really-really needed 1.8.6, thus trying to make it work. But thanks for the tip.

From: Jarmo Pertman on 30 May 2010 09:11 Thank you for this (insight|help)ful reply! I tried your first suggestion which worked as you said! Then i decided to downgrade gcc completely and tried your second suggestion which also worked! Also make test succeeded (although i tried with latest patchlevel, so i'm not sure if it was even related with my problem). But why does 1.8.7 work with gcc 4.4? Is util.c there somehow changed? So in the end it is a incompatibility problem with Ruby 1.8.6 and gcc 4.4 (which comes by default with latest Ubuntu)? Anyway, thank You again!
