Thanks David. Could you give the graphite-branch a run on AIX?
Seb,
What release of G++ are you using to compile PPL?
I initially did not have the C++ interfaces to GMP installed. I fixed that, but I had to compile GMP 4.1.4 with G++ 4.1.
I downloaded the most recent PPL, ppl-0.10pre22 from August 15. When I try to build it on AIX, I first get an error in Bit_Row.inlines.hh because ffs is not declared. The file includes <cstring>, which includes <string.h>, but ffs() is not declared in /usr/include/string.h on AIX, only in, /usr/include/strings.h. I manually declared ffs and proceeded.
But then I receive a more significant C++ error when compiling MIP_Problem.cc:
/usr/gnu/src/ppl-0.10pre22/src/MIP_Problem.cc: In member function 'Parma_Polyhedra_Library::dimension_type Parma_Polyhedra_Library::MIP_Problem::steepest_edge_entering_index() const': /usr/gnu/src/ppl-0.10pre22/src/MIP_Problem.cc:871: error: no matching function for call to 'assign_r(double&, const __gmp_expr<__gmpz_value, __gmpz_value>&, Parma_Polyhedra_Library::Rounding_Dir)' /usr/gnu/src/ppl-0.10pre22/src/MIP_Problem.cc:885: error: no matching function for call to 'assign_r(double&, __gmp_expr<__gmpq_value, __gmpq_value>&, Parma_Polyhedra_Library::Rounding_Dir)'
I tried G++ 4.1, 4.2, and 4.3.
PPL is supposed to compile with g++ 4.0.3 or later. I used g++ 4.2.3 and it worked on Ubuntu (linux-amd64) machine. Roberto, is this a known bug?
The first bug (including <cstring> instead of <strings.h> was unknown and is now fixed in the CVS version.
For the other problem, I am unable to reproduce it on any of our machines. Can I have access to a system where the problem shows up? Cheers,
Roberto
P.S. Please direct all the PPL-related messages to ppl-devel@cs.unipr.it, not to myself.
