I just upgraaded to Linux Mint Debian Edition 5. This requires me to reinstall GNU APL, which was on the root partition, which was wiped and reformatted.
I tried ./configure --with-postgresql RATIONAL_NUMBERS_WANTED=yes but the configure program couldn't find PostgreSQL, even though it is installed. I don't know whether this is because I need to install some optional PostgreSQL package. So then I tried ./configure RATIONAL_NUMBERS_WANTED=yes make and got an error message: In file included from Shape.cc:21: Shape.hh: In member function ‘Shape Shape::insert_axis(Axis, ShapeItem) const’: Shape.hh:68:46: error: ‘*(const ShapeItem*)((char*)& ret + <unknown> *8 +8)’ may be used uninitialized in this function [-Werror=maybe-uninitialized] 68 | loop(r, MAX_RANK) rho[r] = other.rho[r]; | ~~~~~~~~~~~^ cc1plus: all warnings being treated as errors so APL wouldn't compile. So I tried ./configure make and got the same error.
