Problems with old systems that have known work-a-rounds:
|
||||
|
||||
* The gcc as shipped with Redhat 7 perhaps other Linux distributions
|
||||
has a bug causes calc to dump core on startup when calc is:
|
||||
|
||||
compiled optimized (-O, -O1, -O2 or -O3)
|
||||
|
||||
AND
|
||||
|
||||
compiled with debugging (-g or -g3)
|
||||
|
||||
AND
|
||||
|
||||
when calc is compiled with readline (see USE_READLINE,
|
||||
READLINE_LIB and READLINE_INCLUDE in the Makefile)
|
||||
|
||||
This is known as the Redhat 7 readlne problem.
|
||||
|
||||
On Redhat, the gcc -v which has this problem is:
|
||||
|
||||
gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-85)
|
||||
|
||||
there may be other gcc versions that also suffer this fate.
|
||||
|
||||
The readlines associated with problem are:
|
||||
|
||||
readline-4.1-5
|
||||
readline2.2.1-2.2.1-2
|
||||
readline-devel-4.1-5
|
||||
|
||||
One work-a-round is to compile calc WITHOUT readline. In the
|
||||
Makefile be sure that:
|
||||
|
||||
USE_READLINE=
|
||||
READLINE_LIB=
|
||||
READLINE_INCLUDE=
|
||||
|
||||
i.e., these Makefile vars are empty.
|
||||
|
||||
If you must use readline, then an alternate work-a-round is to
|
||||
change the DEBUG Makefile variable to either:
|
||||
|
||||
compile for speed: -O3 (or -O2 if you do not have -O3)
|
||||
compile to debug: -g3 (or -g if you do not have -g3)
|
||||
|
||||
but not both.

* There is a bug in gcc-2.95 that causes calc, when compiled with -O2,

to fail the regression test. The work-a-round is to compile with -O

or to use gcc-2.96 or later.

main(){SVAL(b8a8aeb0,8168eadc);}

|
||||
fails because it puts a space inside the concatenated hex. Calc
|
||||
has code that is affected by this bug. This bug has been reported
|
||||
to Compaq and may be fixed in the future. A work-a-round is to
|
||||
compile with cc -std0 or to use a later version of their compiler.
