Not sure. First of all, GNU APL does not use the symbol _CERR, only CERR without underscore.
However, sometimes linkers add a leading underscore to symbol names under certain circumstances,
snf I duppodr thst is the case here.
Normally CERR is defined in the libapl.so library file:
address@hidden:~/projects/juergen/apl-1.7/src$ nm -D ./.libs/libapl.so |grep CERR
002d5040 B CERR
002d5420 B CERR_filebuf
00119510 T _Z8get_CERRv
002d6460 B _ZN11Performance9fs_CERR_BE
002ca080 D _ZN6Output10color_CERRE
002ca1ec D _ZN6Output21color_CERR_backgroundE
002ca1f0 D _ZN6Output21color_CERR_foregroundE
How3ever, the —with-android ./configure option disables CERR because android
seems not to have the standard input and output streams that Unix resp. C++ have. In that
case you have to provide it yourself somehow.
In Common.hh there is a declaration:
extern ostream CERR;
but the file implementing it (Output.cc line 97 ff.) does not instantiate CERR if compiled for android:
// Android defines its own CIN, COUT, CERR, and UERR ostreams
The comment is slightly misleading: instead of "Android defines its own CIN, ..." it should
read: "Android is supposed to define its own CIN, ..." .
