The PowerPC machine I am using had the folder /tmp mapped into shared memory and the file-locking did not work with it. I changed the sqlite3OsTempFileName() function and everything is fine.
I only wonder, what is the file SQLite creates in /tmp? My program calls "CREATE TABLE", "INSERT" and "SELECT". Why does SQLite need some temporary file?

Still not running on Power PC QNX. I tried to comment out locking in os.c and the test program works fine. So the problem is really hidden in the findLockInfo() & co. functions. Does somebody have some experience?
Thanks, Jakub

Thank you for your help. I am trying to cross-compile SQLite 2.8.15 on QNX-x86 to QNX-PPC. Is it possible to do so with some params for configure?
I tried to create the Makefile for QNX-x86 by just running "./configure" and to change it by hand:
TCC = qcc -g -O2 -V gcc_ntoppc -fno-inline -fno-pack-struct -EB -DOS_UNIX=1 -DOS_WIN=0 -DHAVE_USLEEP=1 -I. -I${TOP}/src
LTCOMPILE = $(LIBTOOL) --mode=compile --tag=CC $(TCC) LTLINK = $(LIBTOOL) --mode=link --tag=CC $(TCC) LTINSTALL = $(LIBTOOL) --mode=install --tag=CC $(INSTALL)
but the libtool linker failed with "/usr/bin/ntox86-ld: warning: powerpc:common architecture of input file '.libs/attach.o' is incompatible with i386 output'
thus I had to change the "libtool" script, replacing "gcc" with "qcc -V gcc_ntoppc". Which does not seem an elegant solution.

Hi Armin,
thank you for your notes. Could you please tell me more about "That's the case"? Is it possible to use SQLite on PPC or not possible? Did you hear about a big-endian port of SQLite?
I've used SQLite on SPARC, PowerPC and PA-RISC, all big endian, with no problems.
The SQLite database file is platform independent, being endian agnostic and 32/64 bit clean.
BTW, you may want to upgrade to a later version of SQLite, 2.8.15 being the latest 2.x release.
Thanks, Jakub

Hello everybody,
does someone have any experience with building for the QNX operating system? And for the Power PC processor?
QNX 6.2.1 is a real-time Linux but it behaves strangely sometimes.
No .. it doesn't behave 'strangely" at all :)
It has not gcc but a qcc compiler.
qcc is only a frontend of the gcc ... so QNX has gcc.
Our testing program runs correctly on
the x86 PC. It creates a database, a table, inserts and selects data.
But the same program cross-compiled on the same computer for PPC ends at
the first "CREATE TABLE" statement with SQLITE_BUSY.
I am using SQLite 2.8.6. Is it possible that the little-or-big-endian thing could cause this trouble?
That's the case ..
Regards
Armin Steinhoff
Or do you have any other ideas?
Thank you very much, Jakub
