atlas @3.8.3 build fails with #error Use the "-maltivec" flag to enable PowerPC AltiVec support

Reported by: jpmasseria@… Owned by: jameskyle@…
Priority: Normal Milestone:
Component: ports Version: 1.9.1
Keywords: Cc: Veence (Vincent)
Port: atlas

Description

I am new to the Mac and also Macports.

I'm actually trying to install gedit which for some reason requires many ports including atlas.

My install of atlas fails with the following error in the error log:

#error Use the "-maltivec" flag to enable PowerPC AltiVec support

I'm running Mac OS X version 10.4.11 on an eMac with a 700 MHz PowerPC G4.

I'm following up on this as an intellectual exercise as I am interested in understanding what's going on.

I have performed:

sudo port -d selfupdate

sudo port clean --all atlas

sudo port install atlas

I was finally able to figure out the problem. The computer I'm using is an eMac that returns "hw.model: PowerMac4,4" for sysctl hw.model

Therefore I had to change the patch for archinfo_freebsd.c to include strstr(res,"c4,4") as shown below:

--- CONFIG/src/backend/archinfo_freebsd.c.orig  2009-02-18 18:47:37.000000000 +0000

                      strstr(res,"c7,2") || strstr(res,"c7,3") ||

The log file now shows:

:info:configure 
:info:configure Maximum number of threads configured as  1
:info:configure Cannot detect CPU throttling.

The build is still running, but I am confident that I have overcome the "-maltivec" flag issue as I can see compiles in the log file now using this option.

I will post my final results later when the build finishes.

Success! Clean build!

:info:build ATLAS install complete.  Examine 
:info:build ATLAS/bin/<arch>/INSTALL_LOG/SUMMARY.LOG for details.
:info:build /usr/bin/make clean

The if statement in archinfo_freebsd.c needs to include strstr(res,"c4,4") for the eMac.

I'm a novice at this so I need to research how to build an official patch and changeset for this.

Is this still a problem with atlas 3.9.33?

Since there is no answer, I close the bug as invalid. Reopen it if this still fails with 3.9.35.

Sorry for the late response.

3.9.35 still fails for me on my eMac.

I had to apply the following patch to get it to work:

But now I'm getting a different error later in the build process. I'm investigating that.

I think now I have the problem described in Ticket #28413.

I just fetched 3.9.37 using:

sudo port fetch atlas @3.9.37

Bottom line is that for an eMac to work you need to include the change I previously documented.

I have committed the patch in r76544. Thanks for digging this out! Please try again, and tell me if it is okay so we can close this bug.

I close this bug. If you're still encountering the same error, reopen it.

Hello Vince,

I reopened this because this is still a problem. You can not build Atlas on a Macintosh eMac without the following patch:

Please integrate this patch into a future version of atlas.

Thank you, John

That patch is already integrated. Check the link in comment:12.

Hi Vince,

Yes you are right, somehow I missed your comment #12. Thanks for integrating the patch.

I'm not sure what an invalid resolution means, I guess I messed up the bug report when I reopened it on 3/2. I thought that it had been set to invalid instead of fixed.

Thanks again, Shouldn't you close this as fixed? John
