So I'm adding an exception to an existing project but have run into an issue. I have the following compiler flags:
OC_COMPFLAGS = -c $(OC_DEBUG_COMPFLAGS) **-q64** -qcpluscmt -qinitauto=00 $(OC_OPT_COMPFLAGS) -D_RWCONFIG_8d -DXML_LIBRARY **-qlanglvl=ansifor:newexcp** -qlonglong -qfuncsect -bnoquite -bloadmap -qnamemangling=v8
The newexcp flag works perfectly except when we add in the -q64 flag - at which point it stops working. Does anyone have an idea why?
This might be applicable - from http://www-01.ibm.com/support/docview.wss?uid=swg1IY20996:
"The user can get new to throw exceptions by adding the following call to their program:
__set_new_throws_exception(true);

I am trying to run the example "optaplanner-mixedvrp-experiment" developed by Geoffrey De Smet and when I run it it throws me the following error:
Caused by: java.lang.IllegalStateException: The entity (MY) has a
variable (previousStandstill) with value (MUNO) which has a
sourceVariableName variable (nextVisit) with a value (WERBOMONT) which
is not null. Verify the consistency of your input problem for that
sourceVariableName variable.
I have not made any change, I have only cloned and executed it, I import and solve it and it throws me this error.
Do you know what could be happening?
I am applying it in the development of a variant of VRP with multiple deliveries and collections, but it throws me the same error. I have activated the FULL_ASSERT mode and nextVisit, previousStandstill, visitIndex are always null
It's been a long time since I looked at that code, so it's using an old version of optaplanner. Our goal is still to clean it up and offer an out of the box example for VRPPD (and probably remove some boilerplate along the way, using the upcoming #CollectionPlanningVariabe etc). That being said, we have multiple users&customers who used that optaplanner-mixedvrp-experiment to successfully build VRPPD implementations.
Which dataset did you try?
FWIW, that IllegalStateException says that when A.previous = B, the B.next is not A. So either the dataset importer didn't import it correctly - before calling solve() - especially if it fails before the first CH step in FULL_ASSERT. Or one of the custom moves corrupted the model.
I have a VxWorks Image Project project without a File-System on MPC5200B, using DIAB tool-chain.
I need to dynamically load a module from flash.
I allocated memory on my stack char myTemporaryModuleData[MAX_MODULE_SIZE]
and filled it with the module data from Flash.
(checked that the binary data is intact)
then i create a memDevice('/mem/mem01', myTemporaryModuleData, moduleReadLength)
open the psuedo-stream int fdModuleData = open("/mem/mem01", O_RDONLY, 777);
when i run int mId = loadModule(fdModuleData, LOAD_ALL_SYMBOLS);
did not see anything in the console after running loadModule();
but mId = 0 which indicates failure :(.
getErrno() returned 0x3D0004 (S_objLib_OBJ_TIMEOUT)
NOTE: it didn't take long at all to fail => timeout?
i tried replacing the module with a simple void foo() { printf(...); } module but still failes with same issue.
tried loading an .out instead of .o
unfortunately, nothing got me nowhere,
How can i know what caused it to fail? (log, last_error, anything i should check?)
FOUND IT.
Apparently, it was a mistake in the data read from the flash.
What I can contribute is that 'loadModule()' from memDrv device is possible and working.
I have downloaded wxWidgets-3.0.2 and am trying to create a simple FRAME from the main program.
Unfortunately I am receiving multiple errors that are all to do with wxWidgets, NOT my code. This is odd as I am lead to believe wxWidgets should work.
Here are some of the errors I am getting:
*\msw\chkconf.h(19): Error! E080: col(10) "wxUSE_ACTIVEX must be defined."
\msw\chkconf.h(394): Error! E080: col(13) "wxUSE_DATAOBJ requires wxUSE_OLE"
\msw\chkconf.h(414): Error! E080: col(13) "wxMediaCtl requires wxActiveXContainer"
\chkconf.h(1630): Error! E080: col(13) "wxRearrangeCtrl requires wxCheckListBox"
\vector.h(197): Error! E148: col(71) access to private member 'reverse_iterator::m_ptr' is not allowed
\vector.h(187): Note! N392: col(21) definition: 'wxToolTip * * wxVector<wxToolTip *>::reverse_iterator::m_ptr'*
Why am I receiving these messages when wxWidgets is supposed to be ready to go?
Have you configured properly? If not try this link to configure on Windows. Also, you can try to use Linux. It is much easier to set up WxWidgets.
High level steps to installing wxWidgets:
Download ( you appear to have done this )
Build library ( I cannot tell if you have done this )
-OR-
Download binary built libraries if available for your compiler ( what compiler are you using - you haven't told us! )
Build one or two of the sample programs ( It really does not look like you have done this )
NOT UNTIL you have completed all these steps are you "ready to go"
When I hit a breakpoint in a VLAB script, how can I find out if I have caused elaboration to finish or not, yet?
My script reaches a statement that raises an error:
Error: (E529) insert module failed: elaboration done
(The command that causes this is vlab.instantiate("stim", "stim"))
So obviously elaboration was unexpectedly (for me) already completed. I need to somehow go back in the process and find out where that happened - so I need some way of asking "is elaboration complete?" at the point where I set breakpoints earlier in the script.
SystemC provides the following function to query the current phase of elaboration or simulation.
sc_status sc_get_status();
It returns either SC_ELABORATION, SC_BEFORE_END_OF_ELABORATION, SC_END_OF_ELABORATION, SC_START_OF_SIMULATION, SC_RUNNING, SC_PAUSED, SC_STOPPED, or SC_END_OF_SIMULATION.
See section 4.5.8 in the SystemC Language Reference Manual for more details. Note that this function was only added in the most recent version of the standard, IEEE Standard 1666-2011.
In VLAB, the SystemC API is available from the sysc Python package, so the following script can be used to test if the current phase is at elaboration:
import sysc
print "Is elaboration phase:", sysc.sc_get_status() == sysc.SC_ELABORATION
For some reason, a simple piece of decorator-code fails on my production machine, but runs fine on development[1].
I dumbed it down, and found that the following is the simplest failing piece:
Spree::Variant.class_eval do
def price=(value)
self.price = normalize_number(value)
end
end
Failing with SystemStackError (stack level too deep):
Debugging shows me that, indeed, the function keeps being called. self.price= calls price=.
What is a usual Rails/Ruby pattern to tackle this? What I want is:
When attribute_foo=(bar) gets called, delegate it to my custom code, where I can run the passed bar trough a small piece of custom code. Then assign that altered bar to attribute_foo.
[1]:
The only difference is the Ruby patch version and the fact that the production machine has 64-bit version, versus 32bit-version on dev: ruby 1.8.7 (2011-02-18 patchlevel 334) [x86_64-linux].
The solition was simple: just use write_attribute.
Spree::Variant.class_eval do
def price=(value)
write_attribute(:price, bar(value))
end
end
