tuponeFlash: Previous check was "10.1.0" >= "4.3" and it did not succeed.18:46
tuponethe only comparison could be made as string as 10.1.0 is not a number18:46
tuponethe change is to make each version piece as a 2 digit number and concatenate all18:47
BZNotifybzflag: atupone commented on pull request #253 "Better gcc compiler version check. Previous check failed for gcc-10" (https://git.io/Jf0Rj): > Can you please describe the motivation for this change?...18:55

blast007tupone / Flash: is this a better option?  https://www.gnu.org/software/autoconf-archive/ax_compare_version.html21:00

FlashI'm not skilled at autoconf at all, but on the surface that looks good to me21:01

tuponeblast007: the oldest one was not working21:08
tuponewith gcc-1021:08
tuponeanother option would be to test if mtune work by compiling a little program or if mtune=native works21:09
blast007tupone: "oldest one" referring to what?21:10
tuponethe one that is in 2.421:10
tuponeif you compile with gcc-10 it selects -march=k821:10
blast007we don't have ax_compare_version.m4 in 2.421:11
tuponewe have a test in configure.ac that select -march or -mtune in 2.421:12
blast007We currently do a string comparison.  I'm suggesting the use of that M4 macro that is designed to compare versions.21:12
tuponeI have not found one. If you have, good21:13
blast007I linked to one..21:13
tuponelemme check21:13
Flashwe probably need to download it and put it in our m4 directory21:14
blast007yeah21:15
tuponeit seems good. I thought it could be one outside. That is why I did not commit :)21:15
FlashI seem to recall having to add another m4 macro before ... good find blast00721:15

Flashtupone: are you going to replace with ax_compare_version?22:51
FlashI pasted your change into a shell and I got 4.2.1, not 040201, so I must be missing something22:52
blast007yeah, my gcc's -dumpversion just shows 822:58
FlashI'm not clear on where the $host_vendor comes from or what "pc" means22:59
blast007yeah, I'm not sure where that is coming from.  There's a AC_CANONICAL_HOST macro that is suppose to compute that, but we're only calling AC_CANONICAL_TARGET in configure.ac23:04
*** I_Died_Once <I_Died_Once!~I_Died_On@unaffiliated/idiedonce/x-1828535> has joined #bzflag23:07
blast007Flash: the "pc" vendor seems to just refer to an "IBM PC compatible"23:13
Flashso basically, anything with an Intel/AMD chip?23:31
blast007I assume so23:49
blast007I couldn't find a lot of info about it.23:50
