gcc-10 branch builds out version 12 ALL THE TIME ?

gcc-10 branch builds out version 12 ALL THE TIME ?

[Pei Jia]

Hello:

I'm facing this issue addressed at 
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100101 
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100101> and 
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100102 
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100102> . My environment 
is Ubuntu 20.04. The current gcc version is of 10.3.0, from the default 
repo. I was trying to rebuild gcc by checking out the branch gcc-10:

    /➜  gcc git:(gcc-10) ✗ git remote -v/
    /origin    git://gcc.gnu.org/git/gcc.git (fetch)/
    /origin    git://gcc.gnu.org/git/gcc.git (push)/
    /➜  gcc git:(gcc-10) ✗ echo "$(git branch -vv)"/
    /* gcc-10 461f937b472 Daily bump./
    /  master 461f937b472 [origin/master] Daily bump./


However, even if it's successfully built, it built out  a version of 12, 
which is NOT what I expect.

    /➜  gcc git:(gcc-10) ✗ gcc --version//
    //gcc (GCC) 12.0.0 20210627 (experimental)//
    //Copyright (C) 2021 Free Software Foundation, Inc.//
    //This is free software; see the source for copying conditions. 
    There is NO//
    //warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR
    PURPOSE./

My configuration to build *gcc-10* is as:

    /➜  gcc git:(gcc-10) ✗ $PWD/../gcc/configure --prefix=/usr/local
    --enable-languages=c,c++,fortran,go --enable-multilib /

Can anybody give me a hand please?


Thank you very much


Best Regards

Pei

git gcc-desr 461f937b472 shows
r12-1830

it looks like you're on the main trunk but not releases/gcc-10.

Re: gcc-10 branch builds out version 12 ALL THE TIME ?

[Pei Jia]

I now tried

commitr11-8201-g2efbbba16a0630fac8cadcd6d9e0ffaabfadb79f  <https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=2efbbba16a0630fac8cadcd6d9e0ffaabfadb79f>


It built out *gcc-11.0.1*


/➜  bin gcc --version/
/gcc (GCC) 11.0.1 20210415 (experimental)/
/Copyright (C) 2021 Free Software Foundation, Inc./
/This is free software; see the source for copying conditions. There is NO/
/warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR 
PURPOSE./


Any further suggestions?


Cheers

Pei

on your GCC master repo try
git worktree add ../gcc-10 -b releases/gcc-10 origin/releases/gcc-10

Then build for ../gcc-10 repo.

Re: gcc-10 branch builds out version 12 ALL THE TIME ?

[Pei Jia]

Do you mean *releases/gcc-10* ?


/➜  gcc git:(master) ✗ git worktree add ../gcc-10 -b releases/gcc-10 
origin/releases/gcc-10//
//Preparing worktree (new branch 'releases/gcc-10')//
//fatal: A branch named 'releases/gcc-10' already exists.//
//➜  gcc git:(master) ✗ git checkout releases/gcc-10//
//Updating files: 100% (32377/32377), done.//
//Switched to branch 'releases/gcc-10'//
//Your branch is up to date with 'origin/releases/gcc-10'./

Why would you use that commit?

Obviously. Because you used commit r11-8201.

Use the releases/gcc-10 branch, and make sure it matches
origin/releases/gcc-10 (and is not a copy of trunk that you've called
gcc-10 somehow).

The problem is your use of git, not GCC.

Re: gcc-10 branch builds out version 12 ALL THE TIME ?

[Pei Jia]

Due to these 2 issues:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100101 
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100101>

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100102 
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100102>

But it's obviously not going to give you a build of GCC 10. What I
mean is why would you use that commit when you're trying to build the
GCC 10 branch?

If you use a commit on the gcc-11 branch, then of course you will get GCC 11.x

Note both your local branches `gcc-10` and `master` point to `461f937b472`, which means that your 
`gcc-10` is a copy of `master`. Building on your working tree has the same effect as building on the 
master branch, which of course gives you GCC 12.


In order to build the desired GCC 10 branch, you can either checkout `origin/releases/gcc-10`, or 
make your local `gcc-10` point to `origin/releases/gcc-10`, throwing away any changes, with

   git checkout gcc-10       # `git switch gcc-10` is recommended
   git reset --hard origin/releases/gcc-10
