undefined reference toC/C++

C/C++: undefined reference to `function' — collect2: error: ld returned 1 exit status

The linker can’t find the definition of a function or variable that was declared and used.

fatal error: No such file or directoryC/C++

C/C++: fatal error: foo.h: No such file or directory — #include not found

The preprocessor cannot find a header named in `#include`: wrong path, missing include directory (-I), or the library is not inst…

redefinition ofC/C++

C++: error: redefinition of 'class X' / multiple definition — missing include guard

The same class, struct or function body was included twice in one translation unit because the header has no include guard.

not a member of stdC/C++

C++: error: 'optional' in namespace 'std' does not name a template type — wrong -std standard

The standard-library feature you used needs a newer C++ standard than the compiler is currently set to.

undefined reference to mainC/C++

C/C++: undefined reference to `main' — (.text+0x20) in crt1.o

The linker has no `main` function: the file with `main` is not compiled or linked, or `main` is spelled or declared incorrectly.

No rule to make targetC/C++

Make: *** No rule to make target 'foo.c', needed by 'foo.o'. Stop.

`make` was asked to build a file for which there is no rule and no existing file — a missing source, a typo in the Makefile, or a…

missing separatorC/C++

Make: Makefile:5: *** missing separator. Stop. (spaces instead of a tab)

A line in the Makefile is neither a rule, a variable assignment nor a tab-indented command — nearly always spaces used where a TA…

Two steps away (12)

ELIFECYCLEnpm

npm ERR! code ELIFECYCLE / Command failed with exit code 1

An npm script (build, start, test, postinstall) exited with an error. ELIFECYCLE is only the wrapper — the real error is printed…

gyp ERR!npm

gyp ERR! build error / node-gyp rebuild failed

A dependency with native C/C++ code couldn’t compile — missing build tools, Python, or an unsupported Node version.

COPY failedDocker

COPY failed: file not found in build context / "/app/x": not found

The Dockerfile COPY refers to a path outside the build context, excluded by .dockerignore, or relative to the wrong directory.

command not foundLinux

bash: command not found

The shell can’t find an executable with that name in any directory on your PATH.

incomplete typeC/C++

C++: error: invalid use of incomplete type 'class X' — forward declaration only

You used a class that has only been forward-declared (so its size and members are unknown) where the full definition is required.

implicit declaration of functionC/C++

C: warning: implicit declaration of function 'foo' [-Wimplicit-function-declaration]

In C you called a function the compiler has not seen declared — usually a missing `#include`. Newer compilers treat it as an erro…

multiple definition ofC/C++

C/C++: multiple definition of `x'; first defined here — ld returned 1 exit status

The linker found the same function or global variable defined in two object files — usually something defined in a header.

was not declared in this scopeC/C++

C++: error: 'x' was not declared in this scope (undeclared identifier)

The compiler met a name it has never seen: it is misspelled, declared later, out of scope, or its header or namespace is missing.

does not name a typeC/C++

C++: error: 'string' does not name a type

Where the compiler expected a type, it found a name it does not know as one — a missing header, namespace, or class declared late…

undefined reference to vtableC/C++

C++: undefined reference to `vtable for X' — virtual function not defined

The linker cannot find the class's virtual table, which means at least one virtual member function was declared but never defined…

undefined reference to pthread_createC/C++

C/C++: undefined reference to `pthread_create' — missing -pthread (also `dlopen`, `clock_gettime`)

Your program uses threads (or another system library) but the linker was not told to link it.

LNK1104C/C++

MSVC: fatal error LNK1104: cannot open file 'foo.lib' (or 'app.exe' while it is running)

The Visual C++ linker could not open an input library or the output file — the path is wrong, the library is missing, or the .exe…
