While compiling on x64 plattform I am getting following error:
c:\codavs05\hpsw-sc\ovpacc\tools\codaaccesstest\coda_access.cpp(1572): fatal error C1001: An internal error has occurred in the compiler.
(compiler file 'f:\dd\vctools\compiler\utc\src\p2\sizeopt.c', line 55)
To work around this problem, try simplifying or changing the program near the locations listed above.
Please choose the Technical Support command on the Visual C++
Help menu, or open the Technical Support help file for more information
------ Build started: Project: asyncexample, Configuration: Release Win32 ------
If I change settings to preprocessor file (Yes) i am not getting any error.
About my environment: Upgrading Microsoft Visual Studio 2005 to 2010
Please help.
I have had this problem with VS2015 while building locally in Windows.
In order to solve it, I deleted my build folder (Output Directory as seen in Properties/General) and rebuilt the project.
This always seems to help when strange things happen during the build.
I’ve encountered this error many times in VC++. Do the following steps. They’ve sometimes helped me with this issue:
Take a look at the exact location, pointed out by compiler error.
Find any external types or classes used there at that location.
Change the order of “include path” of those files found in step 2 and rebuild the solution.
I hope that help !!!!
I am getting same error with VC2012. Setting up the project properties Optimization to Disabled (/Od) resolved the issue.
In my solution, i've removed output dll file of the project, and I've made project rebuild.
I encountered the same error and spent quite a bit of time hunting for the problem. Finally I discovered that function that the error was pointing to had an infinite while loop. Fixed that and the error went away.
In my case was the use of a static lambda function with a QStringList argument. If I commented the regions where the QStringList was used the file compiled, otherwise the compiler reported the C1001 error. Changing the lambda function to non-static solved the problem (obviously other options could have been to use a global function within an anonymous namespace or a static private method of the class).
I got this error using boost library with VS2017. Cleaning the solution and rebuilding it, solved the problem.
I also had this problem while upgrading from VS2008 to VS2010.
To fix, I have to install a VS2008 patch (KB976656).
Maybe there is a similar patch for VS2005 ?
I got the same error, but with a different file referenced in the error message, on a VS 2015 / x64 / Win7 build. In my case the file was main.cpp. Fixing it for me was as easy as doing a rebuild all (and finding something else to do while the million plus lines of code got processed).
Update: it turns out the root cause is my hard drive is failing. After other symptoms prompted me to run chkdsk, I discovered that most of the bad sectors that were replaced were in .obj, .pdb, and other compiler-generated files.
I got this one with code during refactoring with a lack of care (and with templates, it case that was what made an ICE rather than a normal compile time error)
Simplified code:
void myFunction() {
using std::is_same_v;
for (auto i ...) {
myOtherFunction(..., i);
}
}
void myOtherFunction(..., size_t idx) {
// no statement using std::is_same_v;
if constexpr (is_same_v<T, char>) {
...
}
}
I had this error when I was compiling to a x64 target.
Changing to x86 let me compile the program.
Sometimes helps reordering the code. I had once this error in Visual Studio 2013 and this was only solved by reordering the members of the class (I had an enum member, few strings members and some more enum members of the same enum class. It only compiled after I've put the enum members first).
In my case, this was causing the problem:
std::count_if(data.cbegin(), data.cend(), [](const auto& el) { return el.t == t; });
Changing auto to the explicit type fixed the problem.
Had similar problem with Visual Studio 2017 after switching to C++17:
boost/mpl/aux_/preprocessed/plain/full_lambda.hpp(203): fatal error C1001: An internal error has occurred in the compiler.
1>(compiler file 'msc1.cpp', line 1518)
1> To work around this problem, try simplifying or changing the program near the locations listed above.
Solved by using Visual Studio 2019.
I first encountered this problem when i was trying to allocate memory to a char* using new char['size']{'text'}, but removing the braces and the text between them solved my problem (just new char['size'];)
Another fix on Windows 10 if you have WSL installed is to disable LxssManager service and reboot the PC.
When I compile a project using cross compiler,I come across the following error:
internal compiler error: in decode_addr_const, at varasm.c:2632
Where can I find the varasm.c file?I searched the project directory and cross compiler directory,but I didn't find it.
Thanks for helpping,Light
The compiler maker has that file, and probably won't give it to you.
But as it seems to be an error in the compiler, you can either contact them / file a bug report, or try to avoid the error by changing your code a bit (which is a guessing game, as you don't know how you made it run into the error). Or use another compiler, if there are choices.
We been instructed to eliminate all level 3 warnings and have been specifically told to address C4192.
My code does fall into the "bad code" example that causes C4192
#import "msxml6.dll" named_guids
and the "good code" is easy enough to implement
#import "msxml6.dll" exclude("ISequentialStream","_FILETIME")named_guids
The only problem, is that I just do not get this warning. I'm importing version 6.30.7601.18431 of msxml6.dll, and no matter what I do, this warning just does not manifest.
I also imported it again, specifying the no_auto_exclude option and could find no reference to ISequentialStream or _FILETIME in the generated tli and tlh files.
I'm about to simply update to use the "good" code and go on, but I'd still like to know what is happening.
This is specifically an issue because new version of MSXML6.0 changed declarations , especially from Win10 OS onwards.
We already encountered this warning message with our legacy code base having 'bad code' , which you mentioned in your question.
In your case, your system is having older version of MSXML6.DLL (present in "C:\Windows\System32 or SysWow64").
Hope this calrifies your query.
I am testing c++ source codes using the tool cantata++. I created a project, built it and encounter the following error message.
error I9282: the global scope has no "_invalid_parameter" C:\LegacyApp\VisualStudio2005\VC\include\yvals.h 167
I find this error wierd, because yvals.h is not really a file in my source codes. What does this error message imply?
You'll find that yvals.h is probably included by one of the many system header files the Microsoft compiler includes, and you are only seeing it in the error message because the Cantata++ instrumenter is finding a problem with it. My guess would be that there is some problem with the settings in either Cantata++, your Visual Studio project or a mismatch between the two meaning they are not using the same settings.
In order to help diagnose the problem it would help to know a few things about the setup you have, and the code you are building when you get the error.
As Joachim Wuttke said, I would suggest you contact the Cantata Technical Support team directly if you are still having problems with this issue. They will be able to provide you with further information to help solve the problem.
I am currently trying to use the ZXing Library for an iOS Project. However I can't even get the sample Projects to work.
The ScanTest Project, as well as the ones that I created myself throw the following error in the BinaryBitmap.cpp file.
In file included from /Volumes/Macintosh HD/Users/Tim/Downloads/zxing-2.1/iphone/ZXingWidget/../../cpp/core/src/zxing/BinaryBitmap.cpp:20:
../../cpp/core/src/zxing/BinaryBitmap.h:33:7: error: private field 'cached_y_' is not used [-Werror,-Wunused-private-field]
int cached_y_;

1 error generated.
I searched on Google and Stackoverflow, but have not found a solution for the problem.
I have tried it with both the current stable release of XCode and the beta.
I don't know if anybody else has got this problem too, but any help would be greatly appreciated.
This is clang, right? You can read about the relevant compiler options here.
The error message is telling you which compiler flags are relevant.
-Wunused-private-field means you get warnings about private member fields of classes (or structs, ...) that are not used anywhere. The warning is because you probably did mean to use them. This would not normally stop the compilation, but...
-Werror turns warnings into errors. A lot of people use this option to force themselves to write very clean code. Taking this one out should be enough.
