compiling very slow on 6.1

Compiling files takes 2-3 longer than in 6.0. What could the reason be?
Different GNU? Is my harddrive slow? the libaries?

What sort of files?

C++ files, just a two pages long, including a couple of standard libaries
(iostream, fstream, string, stdio, errno), nothing fancy

Make sure you have UDMA enabled if it was enabled in 6.0. On my machine 6.1
installer tells it will enable UDMA by default but that’s shameless lie. I
had to enable it manually and that made big difference in file access speed.
QSSL says they can’t reproduce it somehow :wink:

Thanks… I tried it but I still have problems.
I started thinking it’s related to memory. I have 128Meg, it shows 80Meg is
free, swapfile is enabled.
One file I compiled (about 300 lines), the error message “virtual memory
exceeded” appeared.

Considering that we haven’t been able to reproduce it so far, I would
consider it a “bug” that you’ve encountered rather than a “shameless
lie”. :wink:

Could we get this program to look at it? Did you do a QNX 6.1.0 Upgrade
or a brand new install?

The file is attached. I did a fresh 6.1 install.
I found out that the problems only occur with optimization enabled (-O). I
use “cc”.

This is what I get:
img2source.cpp: In function `void createSource(PhImage_t *, char *)’:
img2source.cpp:141: Internal compiler error.
img2source.cpp:141: Please submit a full bug report.
img2source.cpp:141: See
URL:http://www.gnu.org/software/gcc/faq.html#bugreport for instructions.
cc: /usr/lib/gcc-lib/ntox86/2.95.2/cc1plus error 33

or…
“virtual memory exhausted”

I started thinking it’s related to memory. I have 128Meg, it shows 80Meg is
free, swapfile is enabled.
One file I compiled (about 300 lines), the error message “virtual memory
exceeded” appeared.

Indeed this file ran my machine (256Mb) out of memory, when compiling with
optimisation. :frowning:

Make sure you have UDMA enabled if it was enabled in 6.0. On my
machine
6.1
installer tells it will enable UDMA by default but that’s shameless
lie. I
had to enable it manually and that made big difference in file access
speed.

What sort of files?

The Dinkum C++ seems to compile a lot slower than the GNU C++ libraries
did. We’re looking into it.

Shouldn’t that have been discovered long before now? I mean, if your going
to switch
libs then I would think the new ones would at least be better (meaning
faster) then the
previous ones. Increasing my compile times by a factor of 3 does not make
me want
to use 6.1.

The reason for switch was because the libs were ANSI compliant and that
they contained no GNU code. This is important for some of our large customers.

I’ll be making the GNU C++ libs available as a package soon, as I can understand
that those people who don’t care about GPL issues are miffed about this issue.

Darn! Now we’re gonna have ‘QNX’ and ‘QNX with glibc’. Does not that smell
like a penguin?

No libc, Igor - only libstdc++
