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.

I was able to temporarily get some legacy Fortran code running (I was able to step through it with the debugger) in Visual Studio 2017 with the Intel Fortran compiler, until it stopped working apparently for no reason.
At the very start I was getting the error below when trying to get the code to run.
error #6633: The type of the actual argument differs from the type of the dummy argument.
That error went away after a post-installation reboot and I was able to test the code for a few weeks, but now it's back.
I don't think I've changed any of the code.
You're using Intel Fortran and it has a feature called "Generated Interface Checking". The way this works is when you compile a source that declares a subroutine or function that isn't in a module, it generates an INTERFACE block and saves a compiled module for it. Then when you compile a source that calls a routine for which you have not provided an explicit interface, it looks to see if there's a generated one and compares it. If you have an argument type mismatch you'll get an error such as this.
However, to work properly the called routine must be compiled before the caller. If this doesn't happen, the interface can't be checked and you'll not get an error. The error is still there, and you may be able to see it if you do a rebuild of the project. Pay attention to the message and fix the problem it describes. A mismatched argument type is a common cause of run-time errors that come and go.
I have a __forceinline function that cannot be inlined when compiled as CLI (probably due to the specific restrictions to inlining that apply with .NET).
In debug, it is a warning and does not prevent me from building. But in release, it comes up as an error:
error C4714: function '...' marked as __forceinline not inlined
In the project configuration, Treat Warnings As Errors is set to No (/WX-), Treat Specific Warnings As Errors is empty (no value and no inherited value) and there is no /We option in the Command Line of the C/C++ section.
Thus, I don't understand why this warning comes up as an error.
And as it is an error it prevents me from building the project in release.
Do you have any clue on why this comes up as an error?
Any idea of how I could get rid of it, considering I cannot change the function nor its use (it comes from a library I'm using and I'd like not to alter)?
Thank you very much!
I'm trying to run the example "Scale_Space_Surface_Reconstruction_3" from CGAL library on CodeBlocks IDE on Ubuntu platform, as it would be nice
to have the IDE support for code completion and a more automatic configuration process.
I managed to successfully execute it by compiling it with cmake on the terminal window.
However, on CodeBlocks, after creating a new project and copying the code from the example, I get the following error:
/usr/local/include/CGAL/Scale_Space_Reconstruction_3/Scale_Space_Surface_Reconstruction_Impl_3.h:165:23: error: variable or field 'pca' declared void
Approximation pca( _nn[i]);
By looking inside the code, I found out that this is due to an undefined Macro CGAL_EIGEN3_ENABLED. As my experiment shows, if I define the macro at
pre-processing time, I do not get the same error. That is because, by defining the macro, the type definition Default::Get< wA,void>::type, becomes
Default::Get< wA, Weighted_PCA_approximation_3<Gt>>::type, and the compiler does not complain any more.
Unfortunately, as a deserved prize for messing with things I do not really understand, I get a segmentation fault at runtime.
How should I change the compiler options of codeBlocks to make the compilation succeed, and the executable run successfully?
I have the following include paths:
/usr/local/lib/CGAL/ /usr/local/include /usr/include /usr/include/eigen3.
I also included the following libraries:
libCGAL.so, libCGAL_Core.so, libCGAL_ImageIO.so, libgmp.so, libmpfr.so, libtbb.so, libtbbmalloc.so, libtbbmalloc_proxy.so
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.
