OS Gentoo Linux
Arduino 0022 or 1.0.3 (any)
Standard example: Sensors --> Ping
Getting error during "Verify" process :
core.a(wiring_pulse.c.o): In function `pulseIn':
/usr/share/arduino-0022/hardware/arduino/cores/arduino/wiring_pulse.c:45: undefined reference to `__muluhisi3'
/usr/share/arduino-0022/hardware/arduino/cores/arduino/wiring_pulse.c:68: undefined reference to `__muluhisi3'
collect2: error: ld returned 1 exit status
Any ideas...
Never seen this one on Windows (my OS).
Can you open the faulty file and post the contents?
// my 0.22 IDE has perfectly meaningful code at line 45/68, no mentions of __muluhisi3 in the file.
sure

problems in lines:
unsigned long maxloops = microsecondsToClockCycles(timeout) / 16;
...
return clockCyclesToMicroseconds(width * 21 + 16);
it looks like there is something with definition of clockCyclesToMicroseconds and microsecondsToClockCycles in
/usr/share/arduino-0022/hardware/arduino/cores/arduino/wiring.h file
#define clockCyclesToMicroseconds(a) ( ((a) * 1000L) / (F_CPU / 1000L) )
#define microsecondsToClockCycles(a) ( ((a) * (F_CPU / 1000L)) / 1000L )
thanks
What time out do you use?
Read this thread -http://arduino.cc/forum/index.php/topic,74813.msg563694.html#msg563694 -
See my reply msg10
Which board did you have selected?
robtillaart:
What time out do you use?Read this thread -Why doesn't the pulseIn display duration more than 170ms??? - Programming Questions - Arduino Forum -
See my reply msg10
Thanks again.
I use standard examples Examples --> Sensors --> Ping from arduino package.
It looks like mistake in example
duration = pulseIn(pingPin, HIGH);
here no timeout
Tried your testcode from your thread (post #10), got just one (not two like before) error on line 68:
core.a(wiring_pulse.c.o): In function `pulseIn':
/usr/share/arduino-0022/hardware/arduino/cores/arduino/wiring_pulse.c:68: undefined reference to `__muluhisi3'
collect2: error: ld returned 1 exit status
Your fix is working only on for 45-th line. 
AWOL:
Which board did you have selected?
Arduino Uno
Very interesting.
I made several tests with this easy code:
unsigned long duration;
int counter = 0;
unsigned long before = 0;
void setup()
{
pinMode (5, INPUT);
Serial.begin(9600);
}
void loop()
{
duration = pulseIn(5, LOW, 10000000L); // yes 10.000.000
{
Serial.print("D: ");
Serial.println (duration);
Serial.print("M: ");
Serial.println(millis()-before);
before = millis();
}
}
not working. I got:
core.a(wiring_pulse.c.o): In function `pulseIn':
/usr/share/arduino/hardware/arduino/cores/arduino/wiring_pulse.c:68: undefined reference to `__muluhisi3'
collect2: error: ld returned 1 exit status
File /usr/share/arduino/hardware/arduino/cores/arduino/wiring_pulse.c line 68 (original) :
return clockCyclesToMicroseconds(width * 21 + 16);
If I change it to:
return clockCyclesToMicroseconds(width * 2 + 16);
(I know that there no sense) 
...there no any compilation errors.
As you can see I just changed "21" to "2" 
BTW, code with "3" :
return clockCyclesToMicroseconds(width * 3 + 16);
not working too.
any ideas? :~
PS: Maximum value for "width" i have <= 736.
PPS: Gentoo Linux 64bit
Ha, now I recognize it you got the overflow bug!
I posted it here - Google Code Archive - Long-term storage for Google Code Project Hosting. - Solved in version 1.01 IIRC
OK explanation:
timeout = 10000000L 10 million
#define clockCyclesToMicroseconds(a) ( ((a) * 1000L) / (F_CPU / 1000L) )
#define microsecondsToClockCycles(a) ( ((a) * (F_CPU / 1000L)) / 1000L )
The first macro multiplies 10M * 1000 giving 10 000 000 000 which does not fit in a long ! overflow
The second similar.
#define clockCyclesPerMicrosecond() ( F_CPU / 1000000L )
#define clockCyclesToMicroseconds(a) ( (a) / clockCyclesPerMicrosecond() )
#define microsecondsToClockCycles(a) ( (a) * clockCyclesPerMicrosecond() )
// http://arduino.cc/forum/index.php/topic,74813.0.html
// #define clockCyclesToMicroseconds(a) ( ((a) * 1000L) / (F_CPU / 1000L) )
// #define microsecondsToClockCycles(a) ( ((a) * (F_CPU / 1000L)) / 1000L )
This should solve it,
Succes
Right now I use Arduino 1.0.3
File /usr/share/arduino/hardware/arduino/cores/arduino/Arduino.h has the following definitions:
#define clockCyclesPerMicrosecond() ( F_CPU / 1000000L )
#define clockCyclesToMicroseconds(a) ( (a) / clockCyclesPerMicrosecond() )
#define microsecondsToClockCycles(a) ( (a) * clockCyclesPerMicrosecond() )
F_CPU = 16 000 000
-----> clockCyclesPerMicrosecond = 16
"width" value (in my tests) was not more 736 (~550-736) ---> about 7-13 centimeters
(I temporary changed return value in wiring_pulse.c to get width from there)
File /usr/share/arduino/hardware/arduino/cores/arduino/wiring_pulse.c
return clockCyclesToMicroseconds(width * 21 + 16);
and problem still exists. 
736 * 21 + 16 = 15472 (should be an unsigned long as width is an unsigned long)
this is divided by 16 = 967
The math stays within the range.
// other line of thought
How much free ram has your application?
Which board are you using?
Can you post the complete sketch? might give some clues..
