This extension has been updated to fix permissions.

Would it be possible to recompile this extension with the switch "--enable-cxx" to build the libgmpxx c++ lib?

Edit: ..and if possible, build it with CPPFLAGS=-fexceptions ./configure ... so that I can use the extension to build ppl/cloog

[robc]

I rebuilt libgmp with those options but libgmpcxx is failing in some of its tests and is causing make check to abort. All of the test for libgmp pass.
The failed tests are:
t-assign
t-constr
t-rand
I'll see what I can find about this.

Edit: After looking into this further, the tests are failing to catch the expected exceptions. I editted the test source code to try and catch all exceptions but still does not work...this looks like a bug in the gcc exception handling?

[Juanito]

I got the same 3 tests failing.

I used gmp, mpfr, ppl and cloog to build gcc-4.4.0 making two ./configure runs:

1. With CFLAGS and CXXFLAGS unset
2. Adding "-march=i486 -mtune=i686 -pipe" to whatever CFLAGS and CXXFLAGS resulted from 1. above

Then when I recompiled gmp with gcc-4.4.0, all of the tests passed.

I'll try again with the tc version of gcc and see what happens

Edit: so even when I recompile gcc-4.2.2, the same three tests fail.

[robc]

Edit: so even when I recompile gcc-4.2.2, the same three tests fail.

So this would mean its a bug in gcc and not the configuration or libstdc++?
Is gcc going to be updated to 4.4.0 then?

[Juanito]

tinycore was compiled with gcc-4.2.2, so I'm not sure we should replace it.

I could post gcc-4.4.0 (if you post libgmp with the c++ lib  ) for those that would like to play with it? Note that there are a couple of gcc-4.2.2 libs in the base, which might clash with any newer versions of gcc in /usr/local

[robc]

If you already have libgmp built with gcc-4.4.0 then you can go ahead and submit it. Otherwise I can rebuild libgmp if the gcc-4.4.0 is posted.

[Juanito]

OK - I'll try to get around to this in the next few days.
