file not found: libptcblas.a

[veilleuxanthony@…]

This is my first foray into MacPorts, so if there's something I'm missing, I apologize. I'm trying to install Atlas, and I'm getting the following output:

--->  Computing dependencies for atlas
--->  Staging atlas into destroot
Error: Target org.macports.destroot returned: shell command "cd /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_math_atlas/work/atlas-3.8.3/build/lib &&  ld -arch ppc -dynamic -dylib -single_module -dead_strip -x  -all_load -L. -L/opt/local/lib/gcc43 -ldylib1.o -dylib_install_name /opt/local/lib/libptcblas.dylib libptcblas.a -o  libptcblas.dylib -latlas  -lSystem" returned error 1
Command output: ld: file not found: libptcblas.a

Error: Status 1 encountered during processing.

I'm running MacPorts 1.8.1 on OSX Leopard 10.5.8, Xcode version 3.1.3. My processor is a PPC G5.

I think the easiest fix (since it seems to be a problem with my machine rather than MacPorts as a whole) would be for someone to send me the libptcblas.a library. I tried to find it via the usual channels (Google) but no one seems to have a direct download.

I just built atlas on macports 1.8.1 osx 10.5 most recent patch level, xcode 3 on a powermac g5.

The library you're seeing is never actually intalled. During the destroot phase I have to create dylib (dynamic libs) manually from the library archives as they are not built by default. The only libraries installed are these:

  /opt/local/lib/libatlas.dylib
  /opt/local/lib/libcblas.dylib
  /opt/local/lib/libf77blas.dylib
  /opt/local/lib/liblapack.dylib
  /opt/local/lib/libptcblas.dylib
  /opt/local/lib/libptf77blas.dylib

The error you're receiving indicates a failure further up the build process.

Please provide the output of port -v build atlas after cleaning (port clean atlas)

It seems like it's working, simply by turning the -v flag (which doesn't really make sense). I'll let you know once the build completes.

This is the tail end:

make -f Makefile INSTALL_LOG/dMVRES pre=d 2>&1 | ./xatlas_tee INSTALL_LOG/dMVTUNE.LOG

make: *** [build] Error 2

Warning: the following items did not execute (for atlas): org.macports.build

The whole log is now attached.

Sign me up as Bitten By This as well. Same problem, same symptoms.

[mara.salvato@…]

The same here. Identical error message...

Browsing through atlas-3.8.3/CONFIG/src/SpewMakeInc.c (search for THREADS) it looks like libptcblas.a and libptf77blas.a are only built on SMP machines, but not on single core machines like my G4 PowerBook.

I believe this is a duplicate of #22378 which has been resolved. Please test and reopen. (changes should be available within 30m of this post)
