If you notice something wrong, strange or broken, try rereading:
|
|
|
|
README.FIRST
|
|
HOWTO.INSTALL
|
|
BUGS (this file)
|
|
|
|
If that does not help, cd to the calc source directory and try:
|
|
|
|
make check
|
|
|
|
Look at the end of the output, it should say something like:
|
|
|
|
9998: passed all tests /\../\
|
|
9999: Ending regression tests
|
|
|
|
If it does not, then something is really broken!
|
|
|
|
If you made and modifications to calc beyond the simple Makefile
|
|
configuration, try backing them out and see if things get better.
|
|

If you have tried all of the above and things still are not right,
|
|
then it may be time to send in a bug report. You can send bug reports to:
|
|
|
|
calc-tester@postofc.corp.sgi.com
|
|
|
|
When you send your report, please include the following information:
|
|
|
|
* a description of the problem
|
|
|
|
* the version of calc you are using (if you cannot get calc
|
|
it to run, then send us the 4 #define lines from version.c)
|
|
|
|
* if you modified calc from an official patch, send me the mods you made
|
|
|
|
* the type of system you were using
|
|
|
|
* the type of compiler you were using
|
|
|
|
* any compiler warnings or errors that you saw
|
|
|
|
* cd to the calc source directory, and type:
|
|
|
|
make debug > debug.out 2>&1 (sh, ksh, bash users)
|
|
make debug >& debug.out (csh, tcsh users)
|
|
|
|
and send the contents of the 'debug.out' file.
|
|
|
|
Stack traces from core dumps are useful to send as well.
|

|
|
importantly, fixes (in the form of a context diff patch) to:

Known bugs:
|
|
|
|
* Calc does not support the #! exec method. For example of the
|
|
following is placed in an executable file (assume the path to
|
|
calc is correct) called /tmp/xyzzy:
|
|
|
|
#!/usr/local/bin/calc
|
|
/*
|
|
* comment
|
|
*/
|
|
print 2+3;
|
|
|
|
Will result in '"tmp" is undefined' and '"xyzzy" is undefined'
|
|
error messages because calc considers $0 as an expression to
|
|
evaluate.
|
|
|
|
* The following file:
|
|
|
|
/* this is bugdemo.cal */
|
|
x = eval(prompt(">>> "));
|
|
print x;
|
|
|
|
when executed as:
|
|
|
|
calc read bugdemo.cal
|
|
|
|
will obtain a prompt from the terminal, print the value but leave
|
|
the terminal in a 'bad' state, as if stty -icanon -echo -echoe
|
|
had been executed.
|
|
|
|
* Dec Alpha Linux compiling with gcc-2.95.1 (or gcc-2.95.2) and
|
|
-O2 fails the regression test with:
|
|
|
|
make -s check
|
|
000: Beginning regression tests
|
|
001: Some of these tests may take a while ...
|
|
002: Within each section, output should be numbered sequentially
|
|
003: parsed global definitions
|
|
004: parsed vrfy()
|
|
005: parsed prob(str)
|
|
006: parsed getglobalvar()
|
|
007: parsed test_booleans()
|
|
008: parsed test_variables()
|
|
make: *** [check] Segmentation fault (core dumped)
|
|
|
|
Other programs have reported problems when compiling -O2 with
|
|
gcc-2.95.1 on the Alpha and Mips.
|
|
|
|
One work-a-round is to not compile with -O2 (perhaps just -O).
|
|
Another work-a-round is not use gcc-2.95.1.

We are sure some more bugs exist. When you find them, please let
|
|
us know! See the above for details on how to report and were to
|
|
EMail your bug reports and hopefully patches to fix them.
