same problem here. "undefined reference to `WinMain". I can create the C files, but not an executable. I am on 2017b not suppose to be a problem. I installed via the add-on manager in MATLAB without errors. C:\Users\ANIRUD~1\AppData\Local\Temp\ccjLOzro.o(.text+0xbb):.c: undefined reference to strrev The functions strrev() available in the string.h library. Functions strrev() including some other string function such as like strupr , strlwr , strrev , which are only available in ANSI C (Turbo C/C++) and are not available in testpoint.c: undefined reference to 'create(double x, double y)' While it is defined in point.c. This is a separate file called testpoint.c: Dec 19, 2010 · test.c:(.text+0x6b): undefined reference to `cos' collect2: ld returned 1 exit status What is weird is that when I try this (without the for loop) : float a = cos(3. 14); printf(" a = %f ", a); I get no errors Can anyone, please help me. Thank you in advance Apart from the causes already discussed, “undefined reference” may also occur because of the following reasons. #4) Wrong Project Type. When we specify wrong project types in C++ IDEs like the visual studio and try to do things that the project does not expect, then, we get “undefined reference”. #5) No Library It looks like you haven't included the headers to define the pardiso functions as using C linkage (no C++ mangling of the names). Also, it seems like a very bad idea to link against 3 incompatible OpenMP libraries and 2 incompatible Fortran run-time libraries in random order. Same problem will happen if a .c file tries to call a function defined in a .cpp file without declaring it with extern “C”.If this happens, ensure you have extern “C” in your header file and that the header file is actually included by the .cpp file before the function is defined.

Jul 25, 2013 · When I also include the display.c file (#include "display.c") i got other Errors. Depending to display.c because the compiler miss some other Functions which are defined / declared in other C-Files. So my question is how can I told Eclipse to include the C-Files from the 3rd party Folders. Thanks Chris

Q: I can compile and link C code just fine, but when I try to compile and link a C++ program from the command line, I get "undefined reference" errors all over the place. Undefined reference to "WinMain@16" in C . Undefined reference to "WinMain@16" in Code::Blocks? Sal P. I am using codeblocks and I just started to try Windows You're declaring all these variable as extern, but they don't seem to actually exist anywhere.When you say extern std::string nomEnnemi;, for example, you're not actually declaring a variable, but simply promising the compiler that it exists in another file.

Aug 07, 2015 · Undefined reference means the compiler can't find the definition of the function. Make sure that you are compiling and linking both main.cpp and Dog.cpp (if you use an IDE you should have all files in the same project). C'est pas une question de PC : les deux cases, c'est des mode de compilation, disons : Debug, c'est pour tout le temps ou tu développe, ça te permet d'utiliser le debugger, etc et Release, c'est quand tu as terminé, que tu veux distribuer ton projet : le fichier .exe est allegé, mais tu ne peux plus utiliser le debugger (entre autre). Jan 17, 2009 · undefined reference to `isDigit' Code: eugene@eugene-laptop:~/cfiles$ cc 12.12.c /tmp/cc7U4qkP.o: In function `convertToPostfix': 12.12.c:(.text+0xd6): undefined reference to `isDigit' collect2: ld returned 1 exit status Jan 18, 2020 · When changing the if value from 0 to 1, the compiler optimizes out the memset call since it is not used afterwards. You can see this by compiling lib.c with the -S option instead of -c and investigating the assembler file generated. Since there is no memset call anymore, the linker is now able to successfully link the generated library. Best
