This is some code to get an environment variable from inside Qt, however, it seems Qt's QProcessEnvironment::systemEnvironment() only reflect a new environment variable change after reboot. So I am thinking about using getenv.
However I got "error C2220: warning treated as error - no 'object' file generated" from this :
QProcessEnvironment env = QProcessEnvironment::systemEnvironment();
const QString ENGINE_ROOT = env.value("ENGINE_ROOT", "") != "" ?
env.value("ENGINE_ROOT","") : QString(getenv("ENGINE_ROOT"));
Don't tell me something like disable /WX or lower W4 to W3, I don't want to hear this, I want to know exactly what cause
no 'object' file generated
.
"error C2220: warning treated as error - no 'object' file generated"
The error already answers your question:
A warning was generated.
Because you have told the compiler to treat warnings as errors, an error occurred.
Because an error occurred, the compiler did not generate an object file.
If you want to know what the original warning means, then you need to ask us about that warning.
I just had this problem. The real source of the confusion is that Microsoft Visual Studio lists the
error C2220: warning treated as error - no 'object' file generated
line separately from the warnings--sometimes even before the warnings--so it is not immediately apparent that the error is related to the listed warnings.
Fix all warnings listed to fix this problem.
I'll address the underlying question instead of the compilation problem.
Environment variables for any process are copied from those of its parent process when your new process is started. From that point, the only thing that can modify them is your process yourself.
In practical terms, this means that going to the Windows dialog box to change environment variables does not change those values for any existing processes. Those changes are applied to the explorer.exe process, and then any new processes launched from Explorer.
There is a possible way for a Windows application to get notified of changes made to environment variables made by Explorer. See How to modify the PATH variable definitely through the command line in Windows for details.
in my case, eliminating all useless 'object' will deal this erro

Whenever I add a third config file to my .immuconf.edn I get:
No configuration files were specified, and neither an .immuconf.edn file nor
an IMMUCONF_CFG environment variable was found
This is driving me crazy since I cant really find anything wrong.
Using this loads thing OK:
["configs/betfair.edn" "configs/web-server.edn"]
however this generated an error:
["configs/betfair.edn" "configs/web-server.edn" "~/betfair.edn"]
This is the content of betfair.edn
{:betfair {:usr "..."
:pwd "..."
:app-key "..." ;; key used
:app-key-live "..."
:app-key-test "..."}}
(where ... is replaced with actual strings)
Why am I getting this error when adding the third file and how can I fix this?
Make sure that the last file specified in your <project dir>/.immuconf.edn (~/betfair.edn) exists in your home directory.
Immuconf does some magic to replace ~ in filenames specified in .immuconf.edn with a value of (System/getProperty "user.home") so you might check if that system property points to the same directory where your ~/betfair.edn file is located.
I have recreated your setup and it works on my machine so it is probably a problem with locations or access rights to your files. Unfortunately, error handling for the no arg invocation of (immuconf.config/load) doesn't help in troubleshooting as it swallows any exceptions and returns nil. That exception would probably tell you what kind of error occured (some file not found or some IO error happened). You might want to file a pull request with a patch to log such errors as warnings instead of ignoring them.
I have reinstalled emacs 24.2.50 on a new linux host and started a new dotEmacs config based on magnars emacs configuration. Since I have used CEDET to some success in my previous workflow I started configuring it. However, there is some strange behaviour whenever I load a C++ source file.
[This Part Is Solved]
As expected, semantic parses all included files (and during the initial setup parses all files specified by the semantic-add-system-include variables), but it prints this an error message that goes like this:
WARNING: semantic-find-file-noselect called for /usr/include/c++/4.7/vector while in set-auto-mode for /usr/include/c++/4.7/vector. You should call the responsible function into 'mode-local-init-hook'.
In the above example the error is printed for the STL vector but a corresponding error message is printed for every file included by the one I'm visiting and any subsequent includes. As a result it takes quite a long time to finish and unfortunately the process is repeated any type I open a new buffer.
[This Problem Is Solved Too]
Furthermore it looks like the parsing doesn't really work as when I place the point above a non-c primitive type (i.e. not int,double,float, etc) instead of printing the type's definition in the modeline an error message like
Idle Service Error semantic-idle-local-symbol-highlight-idle-function: "#<buffer DEPFETResolutionAnalysis.cc> - Wrong type argument: stringp, (((0) \"IndexMap\"))"
Idle Service Error semantic-idle-summary-idle-function: "#<buffer DEPFETResolutionAnalysis.cc> - Wrong type argument: stringp, ((\"fXBetween\" 0 nil nil))"
where DEPFETResolutionAnalysis.cc is the file & buffer I'm currently editing and IndexMap and fXBetween are types defined in files included by the file I'm editing/some file included by the file I'm editing.
I have not tested any further features of CEDET/semantic as the problem is pretty annoying. My cedet config can be found here.
EDIT: With the help of Alex Ott I kinda solved the first problem. It was due to my horrible cedet initialisation. See his first answer for the proper way to configure CEDET!
There still remains the problem with the Idle Service Error (which, when enabling global-semantic-idle-local-symbol-highlight-mode, occurs permanently, not only when checking the definition of the type at point).
And there is the new problem of how to disable the site-wise init file(s).
EDIT2: I have executed semantic-debug-idle-function in a buffer where the problem occurs and it produces a ~700kb [sic!] output. It looks like it is performing some operations on a data container which, by the looks of it, contains information on all the symbols defined in the files parsed. As I have parsed a rather large package (~20Mb source files) this table is rather large. Can semantic handle a database that large or is this impossible and the reason of my problem?
EDIT3: Deleting the content of ~/.semanticdb and reparsing all includes did the trick. I still need to disable the site-wise init files but as this is not related to CEDET I will close this question (the question related to the site-wise init files can be found here).
You need to change your init file so it will perform loading of CEDET only once, not in the hook that will be called for each .h/.hpp/.c/.cpp files. You can change this config as the base, and read more in following article.
The problem that you have is caused because Semantic is trying to analyze header files, and when it tries to open them, then its initialization routines are called again, and again...
The first problem was solved by correctly configuring CEDET which is discribed on Alex Ott's homepage. His answer solves this first problem. The config file specified in his answer is a great start for a nice config; I have used the very same to config CEDET for my needs.
The second problem vanished once I updated CEDET from 1.1 to the bazaar (repository) version, which is explained here and in Alex' article. Additionaly one must delete the content of the directory ~/.semanticdb (which contains the semantic database and was corrupted I guess).
I'd like to thank Alex Ott for his help and sticking with me throughout my journey to the solution :)
My VC++ code was working (executing) perfectly alright & now all of a sudden I don't understand why am I getting the error "Debug assertion failed".
file:f\dd\vctools\crt_bld\self_x86\crt\src\fclose.c.
I am using VS2008 on WIn7 64bit OS.
What might be the reason that a code which was working fine started breaking in this manner all of a sudden without any code changes?
Can anyone kindly help me in getting rid of this error?
I saw in the call stack that the code before this is in the file
C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\crt\src\crt0dat.c
while ( pfbegin < pfend )
{
/*
* if current table entry is non-NULL, call thru it.
*/
if ( *pfbegin != NULL )
(**pfbegin)();
++pfbegin;
}
And yes, fclose() is receiving a null file pointer. I seriously don't understand why is this getting wrong file pointer value, all of a sudden without me doing any change to the code or to the environment.
Could you provide the code which calls fclose()?
I may guess that fopen() failed to open the file returning NULL, e.g. because file doesn't exist. You didn't check for this error and passed NULL handle to fclose().
I get an error while trying to load a DLL generated with swipl-ld in prolog
the predicate that throws the exception is this
initialization(shlib:use_foreign_library('C:/Users/valquiria.duarte/Desktop/dlog-server-0.3-beta-source/dlog-server/output/hash_swi.dll', install)),
and the exception is this one
ERROR: '$open_shared_object'/3: %1 is not a valid Win32 application.
According to this note at ComputerHope, Windows may report this error when the file is missing (or corrupt). It appears the filepath is fully specified in the the call to use_foreign_library, but it's worth double-checking that the path is correct about where the DLL is located.
It seems a little odd that you reported the parametric form of the ERROR message, where %1 is a placeholder for the actual filename. If that was how the error appeared on your computer, it suggests there is some failure to parse the exception details as they were thrown up the handler-chain.
If the message does contain the actual path and filename, then you should confirm their accuracy and the file's existence on the given path. It seems you have correctly called use-foreign_library using SWI-Prolog's preferred syntax of forward slashes in the filepath to separate directories. However it is the Window's operating system (more specifically the system-dependent implementation of dlopen()) that generates the error, and the resulting error message I would expect to contain a filepath and filename that contain backslashes.
I use boost's binary serialization and it worked well until now. I have std::list of pointers to serialize for output (oarchive) but serialization fails inside object's serialize() function with MSVC's dialog:
R6010 -abort() has been called
and such string is printed into console window:
Assertion failed: 0 == static_cast<int>(t) || 1 == static_cast<int>(t), file c:\program files\boost\boost_1_44\boost\archive\basic_binary_oprimitive.hpp, line 91
what does it mean?
Project is pretty big, sources are distributed so I cannot post it's code here, but I tried to simulate this error within simple project - there it works fine what is strange.
P.S. I use boost 1.44 with MSVC2010EE on Windows XP. When I click "retry" on "Debug Error!" window debugger shows arrow on the code line next to serialization archive << myList; line - I mean it seems like error occurred at some destructor or something.
When I make changes inside objects serialize() function - they will be applied just when I rebuild whole project (clean before compiling) - but if I just compile it (where IDE shows that all sources which include changed header are recompiled) - no changes will happen at runtime since last version (I tried with printf()) - that's strange.
Could I occasionally set some critical definitions or something?
The line in question says:
// trap usage of invalid uninitialized boolean which would
// otherwise crash on load.
It looks like at some point you are trying to serialize a bool that hasn't been initialized. Without further code we can't help you find which one.
