Comment:
Discoveries:
In gfan with GCC-4.5.0 on "lena (a k10)" linux box:
{{{
g++ -DGMPRATIONAL -c lll.cpp
}}}
works fine, but
{{{
sage subshell$ g++ -O2 -DGMPRATIONAL -c lll.cpp
/tmp/cchu2txF.s: Assembler messages:
/tmp/cchu2txF.s:5145: Error: symbol
`_ZZN6MatrixIiEixEPiPP6VektorIiEiE19__PRETTY_FUNCTION__' is already
defined
}}}
Doing make after compiling without -O2 gives:
{{{
...
g++ -O2 -DGMPRATIONAL -g -c linalg.cpp
linalg.cpp:528:1: error: ‘FieldMatrix::FieldMatrix’ names the constructor,
not the type
make: *** [linalg.o] Error 1
