Re: Is --enable-64 still experimental?

[Chechu Garguez]

So, for sure it's not a clean way to accomplish it, but for been able of compiling image pkg on 64bit systems we have commented out two of the three alternatives that give ambiguous resolution for gcc:


#octave/oct-inttypes.h


//operator T (void) const { return value (); }

operator double (void) const { return double_value (); }

//operator float (void) const { return float_value (); }

With that, mkoctave is cable of compiling the image 2.4.0 package and we can use its functions.

We had left out "operator double" because it seems to be the option that could generate double memory variables and could contain more data on it.

Are we doing right? Should we use "operator T" insted? Is there any better way to accomplish it? We had read ancient bug reporting and OF-packages status but we had not been able of finding other solutions.

Thankyou so much in advance,

Your sincerly , Jose

The test suite contains tests for load/save, I presume?

I've been using 64-bit indexing builds for several months now on Windows and
I saw no issues with load/save, neither with Octave-generated nor
Matlab-generated .mat files. I can't vouch for other file types.
Apart from that, __run_test_suite__.m shows a number of failed tests that
pass on 32-bit and --enable-windows-64 MinGW builds.

On Linux I've got a 64-bit idx build (4.1.0+) made with MXE along the lines
you've sketched in a bug report discussion some months ago; I do not use
Octave that much on Linux so I didn't test thoroughly but overall that build
works fine as well. Some tests did fail when run manually.

There are however still issues with several OF packages. See the task
tracker task #13313, the OF package issues mentioned there are equally valid
for Linux.
