Hello,
I'm attempting to build QFC for the first time and when I attempt to build sigc++ I get errors in signal.h
33: typedef size_t size_type; - ISO C++ forbids declaration
34: typedef ptrdiff_t difference_type - ISO C++ forbids declaration
and similarly in signal_base.h
45: typedef size_t size_type; - ISO C++ fobids declaration
I am running Momemtics Version: 4.0.1 Build id: I20070321
Thanks in advance,
Gordon Molek

Hi Gordon,
This is an error on my part (sorry). Momentics base directory used to be QNX630, but it is now QNX632.
Here is how to fix this.
1. right-click on the "sigc++" project and then select "properties".
2. on the properties dialog select "C/C++ build"
3. on the "configuration" drop-down, select the build target (unfortunately, the following steps need to be performed
for each build target)
4. once you have the desired build target selected, then under "QCC Compiler", select the "General" item
5. you should now see a text field titled "Other Options"; in this field change all references to QNX630 to QNX632
That should do it. I'll update this in the next few days. Thanks for pointing this out!

Rennie,
Thanks, now we can build.
I've attempted to run the RAM disk example. I've copied the libsigc-2.0_g.so and libqfc_g.so libraries to the target
and placed them in /lib. The RAM disk application runs and is receive blocked until I attempt to do anything signficant
to it, e.g., ls -l /mount-point, cd /mount-point, etc., at which point it terminates. Running in the debugger doesn't
help much as I don't know how to set it up yet to see all the necessary source (I only see the main() source for the ram
disk application.
Thanks,
Gordon Molek

Hi Gordon,
What is your command line invocation for Ramdisk?
It requires a single argument (which is the mountpoint of the ramdisk). Since it is intended as example code, the error
handling of detecting a NULL argv[0] is omitted...
Thanks,
Rennie

Rennie,
In the "Arguments" tab of the "Open Launch Config" pane reached via "Run As->C/C++ QNX Conn" menu I simply but "/ramdisk
". Did you mean to say "argv[1]" as isn't argv[0] the programe's name, supplied by the fork/exec?
Also, is there any way to set up my account to receive e-mail notification when a post in made to the forum?
Thanks,
Gordon

Gordon,
Are saying you started Ramdisk like so:
# Ramdisk /ramdisk ?
If so then this should work. Can you get a back-trace from gdb?
You can certainly get notification of posts, by clicking on the "monitor" button for the forum.
Thanks,
Rennie

Rennie,
I would be happy to provide a backtrace if you can provide me with instructions on how to do so (I am new to QNX).
Thanks regarding the "Monitor" button. I wasn't looking for it at that level of the forums.
Gordon

I Gordon,
Sorry, I thought I had responded. The fact that you have list corruption implies a build error.
Could you clean the library, re-build and download to target, and then rebuild Ramdisk and try again?
I have tried it here (from the repository) and it works fine for me.
Thanks,
Rennie

Rennie,
Thanks for the response. I did a fresh check-out, fixed the libsigc++
include file reference problem, downloaded libsigc-2.0_g.so and
libqfc_g.so to /lib on the target and ran Ramdisk_g from within
Momentics, setting its argument to the mount point "/ramdisk". It seems
to run and I can do an "ls -l /ramdisk" which returns an empty
directory, but when I attempt to copy a file into the /ramdisk directory
I get the error message "Can't open destination file. (/ramdisk/foo):
Resource temporarily unavailable"
Thanks,
Gordon Molek
