unsigned long array problem with linux

Sisophon2001 · Post by **Sisophon2001** » Sep 25, 2005 16:08

Hi

This code is giving me problems, with the numbers in the unsigned range. The first number prints correctly, the second is wrong. It works correctly in windows.

I tested with FB-v015b-aug-27-testing-linux and CVS head.

Thanks

Garvan

Code: Select all

dim shared as unsigned long start_P (0 to 17) = { _
		&h243f6a88, &h85a308d3, &h13198a2e, &h03707344, _
		&ha4093822, &h299f31d0, &h082efa98, &hec4e6c89, _
		&h452821e6, &h38d01377, &hbe5466cf, &h34e90c6c, _
		&hc0ac29b7, &hc97c50dd, &h3f84d5b5, &hb5470917, _
		&h9216d5d9, &h8979fb1b _
		}

	for i = 0 to 17
		print start_P(i);" ";
	next
	sleep

And the ERROR is with FB 0.15 from 25/SEP/2005 too.

I can reproduce this behaviour with the DOS and Cygwin versions too. I'll take a look at this ASAP.

EDIT: The current work-around is to add a "u" to all numbers >= &H80000000.

Example:

Code: Select all

dim shared as uinteger start_P (0 to 17) = { _
	&h243f6a88 , &h85a308d3u, &h13198a2e , &h03707344 , _
    &ha4093822u, &h299f31d0 , &h082efa98 , &hec4e6c89u, _
    &h452821e6 , &h38d01377 , &hbe5466cfu, &h34e90c6c , _
    &hc0ac29b7u, &hc97c50ddu, &h3f84d5b5 , &hb5470917u, _
    &h9216d5d9u, &h8979fb1bu _
}

for i = 0 to 17
	print right$("0000000" + hex$(start_P(i)),8),
next
print
sleep

Fixed, changes are in CVS.

Hi mjs

Thanks for your help. I seem to be having trouble with CVS update, so for now I will use your work around of adding a trailing u.

This is the message I get from CVS

can't create temporary directory /tmp/cvs-serv9827
Too many links
Error, CVS operation failed

I assume this is a server problem?

Thanks again

Garvan

Hmm ... maybe but I cannot reproduce this error here ... but I don't use anonymous CVS like you ...

Hello Garvan,
which for a coincidence i tried the whole night out different CVS clients with WINDOWS
and got exactly the same error message.

I was thinking the error came from the local pc and created an extra tmp folder.

But now it must be an problem on cvs.sf.net.
