[Bug bootstrap/44304] New: Building gcc 4.5.0 under Snow Leopard : stages 2 & 3 differ

[doc0 dot delphin at voila dot fr]

OS : Mac OS x 10.6.2 (Snow Leopard)
IDE tools : Xcode 3.2.2

Processor : Intel Core 2 Duo
Memory : 1 GB

Problem :
the make step operates well until teh comparison phase between stages 2 and 3.
Bootstrap matter ...

I have saved the files you need but how to send them to you ?

Yours sincerely,


Laurent Delphin, Dunkerque (EU)

------- Comment #1 from iains at gcc dot gnu dot org  2010-05-28 09:13 -------

first can you give the output from the failure: 
i.e. which files have differences?

...the configuration line you are using.

the output of 
autoconf --version
automake --version
m4 --version

I should remind you of :
http://gcc.gnu.org/install/prerequisites.html

x86_64-apple-darwin10 will not build gcc properly with the auto* tools
installed  - you must ensure that the required versions are found.

MacPorts has accumulated a number of users who seem to run into this issue with
gcc 4.5.0 (apparently always with libgomp)...

https://svn.macports.org/ticket/24664

Peter O'Gorman also has a problem machine as a well (a Mac Mini) which randomly
fails the bootstrap comparison. Oddly I haven't seen this on my MacPro.

If the comparison failure is for libgomp, this pr is a duplicate of pr43170.
The origin of the problem can be seen with the following test:

[macbook] f90/bug% grep -i tls
/opt/gcc/omp_build_w_fail7/stage2-x86_64-apple-darwin10.3.0/libgomp/config.log
| #define HAVE_TLS 1
| #define HAVE_TLS 1
| #define HAVE_TLS 1
| #define HAVE_TLS 1
gcc_cv_have_tls=yes
#define HAVE_TLS 1
[macbook] f90/bug% grep -i tls
/opt/gcc/omp_build_w_fail7/stage2-x86_64-apple-darwin10.3.0/i386/libgomp/config.log
gcc_cv_have_tls=no
[macbook] f90/bug% grep -i tls
/opt/gcc/omp_build_w_fail7/stage3-x86_64-apple-darwin10.3.0/libgomp/config.log
| #define HAVE_TLS 1
| #define HAVE_TLS 1
| #define HAVE_TLS 1
| #define HAVE_TLS 1
gcc_cv_have_tls=yes
#define HAVE_TLS 1
[macbook] f90/bug% grep -i tls
/opt/gcc/omp_build_w_fail7/stage3-x86_64-apple-darwin10.3.0/i386/libgomp/config.log
| #define HAVE_TLS 1
| #define HAVE_TLS 1
| #define HAVE_TLS 1
| #define HAVE_TLS 1
gcc_cv_have_tls=yes
#define HAVE_TLS 1

AFAICT "gcc_cv_have_tls=no" can occur at stage 2 or 3 and in the main lib or in
the i386 one.

4.5-branch (as of r160013) has an error in config.gcc (which I just fixed on
trunk yesterday, with r159979) in which several t-make fragments are included
twice on x86_64-*-darwin*.  

If anyone is interested to try it out I could make you a patch for 4.5-branch
to do the same fix.
still, first we need a repeatable phenomenon - and to be sure that it's not
tool-related.

OK Thank you very much.

I have verified the prerequisites before.
Please note I just send a zip files with all log files.

Thanks.

thanks for posting the files -

It does look like this is the same issue.
However, to confirm: 
Is this phenomenon deterministic - or a random occurrence depending on
processor load?
(as I look at your script, it would seem that you have not done a parallel
build)

if you remove all the libgomp directories and then re-do make - does it succeed
?
