I have been using a graphics library from Smaller Animals Software called ImgSource. Unfortunately, Smaller Animals Software has closed and is no longer available to answer questions. Recently, I had a system failure that deleted my only up-to-date copy of the library (I thought I had a backup but was wrong). I did, however, have the source code. I recompiled the library, both release and debug. (Both are static .lib files) I am also using MSVS 2019 Community edition and the project is an MFC project. The problem, and why I'm posting here, is that when I link the new release library with a previous project, the project compiles properly. However, when I build the debug version, it will compile, but not link and produces the linker error discussed LNK2038: mismatch detected for 'RuntimeLibrary': value 'MT_StaticRelease' doesn't match value 'MD_DynamicRelease' in file.obj
A reasonable conclusion is that there is something wrong with the debug library. However, if I build a new project and link the debug library, everything works fine. So, the error does not appear to be in the library. It seems I could start from scratch and completely redo these projects, but they do reflect a tremendous amount of work.
I can't figure out how to modify the settings in the existing projects so that they will compile in debug mode. I have tried the suggestions offered in the article referenced above. Further suggestions would be greatly appreciated.
I currently run into a problem after I updated my xcode to 4.6.
At the beginning, I got lots of linking errors. With the help from other posts, I am be able to solve them. However, new problems always come whenever I solved the previous one.
Right now, I am stuck at "Undefined symbols for architecture armv7" when I try to build the game on devices with release mode (release and debug modes work for simulator, and debug mode works for devices). I have already researched this problem online, but none of the solutions could solve my situation. That's why I want to start a new post.
Let me explain the situation in details:
All the errors are happened at calling methods in libraries.
my libraries works fine with architecture armv7 before (xcode 4.5)
The current value for Architectures in project file is "Standard (armv7, armv7s)
The current value for Current Architecture is "armv7 armv7s armv6"
This is a sample error:
Even though I only showed errors related to libReceiptVerification.multi.a, errors actually happen at other libraries.
//************* From this line **************
Undefined symbols for architecture armv7:
"_OBJC_CLASS_$_NSMutableOrderedSet", referenced from:
objc-class-ref in libarclite_iphoneos.a(arclite.o)

// *************** Ending Here ***********
So, does anyone has any clue on this problem?
Thanks for your help in advance.
I am having the same problem Solved by setting
Implicitly link Objective-C Runtime Support to NO
You can find it under Project->Build Settings->Apple LLVM Compiler 4.2-Language.
Or search for Implicitly link Objective-C Runtime Support in project->Build Settings
Check out the library targets for libarclite, JSONKit and everything else and make sure they also have the identical architecture values set for their Release builds.
Also that "Build Active Architecture Only" is checked to NO for Release targets.
I have a new project where I cannot use boost::format. I get a compiler error complaining that boost's override of a virtual function, ~basic_altstringbuf, lacks a "throw()". Even the most trivial attempt to use boost::format does that.
I have other projects where it works fine. I have verified that the new project uses the same include-paths for boost, and for the VC++ includes. All the projects have "Enable C++ Exceptions" set to Yes. The only explanation I can come up with is that the projects that work have some #DEFINE or some setting that disables those vile exception specs in the std:: include-files. But I have no idea what or where it might be. Any ideas?
Error 1 error C2694: 'boost::io::basic_altstringbuf::~basic_altstringbuf(void)': overriding virtual function has less restrictive exception specification than base class virtual member function 'std::basic_streambuf<_Elem,_Traits>::~basic_streambuf(void) throw()
EDIT: Corollary question: Is there a Properties-item in VS++ 2012 that will cause the std:: header files to be included without exception-specs? - short of turning off exceptions, that is?
At the request of the original owner of the green check-mark, I am submitting this summary.
The bugs are on the Microsoft side, in header-files for C++ standard library interfaces, and in the VC++ compiler when "Disable Language Extensions" is NOT set. The header files contain exception-specifications that the standard does not call for. When "language extensions" are not enabled, the compiler accepts invalid code. I have filed a bug report.
Boost could work around the problem in this specific case by adding seven characters to a nested include-file, i.e. "throw()" at line 65 in alt_sstream_impl.hpp. I filed a report with boost also, although I made it clear that the bug is not in their code. I am just suggesting a workaround.
All the tedious details are in the two reports linked above.
Check the preprocessor defines.
You might turn on and inspect verbose logging to see the exact flags that are passed to cl.exe
You could keep the preprocessed source and compare the version from the old (working) project with the new (failing) project.
My gut says, something else is being #defined/passed using -D in the old project that is not being defined in the new project, of differently (think of WINVER type macros)
See new answer posted: VC++ 2012 and Boost incompatibility - `throw()` specifications in library headers
EDIT by OP, Jive Dadson - It turned out to be /Za, which enables/disables "Microsoft language extensions." It is the contention of Visual Studio that the C++ standard requires that a program shall not compile if it has a virtual function override that is less restrictive in the "throw()" category than the function it overrides. Boost has a class that derives from basic_streambuf, and has a virtual destructor that lacks "throw()". The original destructor has that evil festoon. My new project will compile boost::format if I turn MS language extensions ON.
So the question becomes, who is wrong, and how? Is it standard-complying to put throw() on that destructor or not? Is the desired behavior (desired by me, that is) actually an "extension"? I seem to recall that MS considered some standard C++11 features to be "extensions," but I am not sure I remember correctly. Anyway, I will leave it to the boosters to decide, if they are interested. https://svn.boost.org/trac/boost/ticket/7477
Hi I have an XCode project which is ARCd but uses some 3rd party (AFNetworking) classes which are not ARCd. I have specified the -fno-objc-arc flag against these files however when I run scan-build I get a number of errors such as:-
error: 'autorelease' is unavailable: not available in automatic reference counting mode
I can see that scan-build is using -fobjc-arc when compiling / checking these classes which is incorrect.
Please could someone advise how I can get scan-build to pick up the correct settings?
FYI I am using checker-267 version downloaded from http://clang-analyzer.llvm.org/
Many thanks
Raised this with the clang team at Apple and they swiftly came back to say that this is a known bug, see:
http://llvm.org/bugs/show_bug.cgi?id=13683
A new version of the checker should be released soon to fix this.
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.

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.
