在Visual Studio C ++中编译时出现错误2，代码退出MSB6006“ CL.exe”

Question

I work on a c++ console project. this project has in msmpisdk platform. When I compiled in Visual Studio 2019 the error below occurred:

"Severity Code Description Project File Line Suppression State...Error MSB6006 "CL.exe" exited with code 2....C:\\Program Files (x86)\\Microsoft VisualStudio\\2019\\Enterprise\\MSBuild\\Microsoft\\VC\\v160-\\Microsoft.CppCommon.targets 429."

I checked my code, it seems OK, also check ref lib of project, it seems OK.

I searched the web.

1. All functions return a value.
2. All variables set a value before using it.
3. I restarted Visual Studio and my computer.
4. I created new project and added the code, but the same error occurred.

but the same error occurred and my code doesn't compile.

Answer 1

at last I found the problem.

• one of my variable ,initialized in algorithm .
• but compiler can not detect variable initialized before and raise error.
• see below code to see how this error raised.

 #include "iostream" class myclass1 { public: int _AMethod() { return 55; } }; int main() { myclass1* myVariable; int x = 0; if (x == 0) { myVariable = (myclass1*)malloc(sizeof(myclass1) * 5); //myVariable = init(); } if (x == 0) { myVariable->_AMethod(); } } 

now when compile this error occurred: Error MSB6006 "CL.exe" exited with code 2.

• all things in algorithm ok..
• but compiler raise error ..

this error can solved easily .. with init in definition, like below :

 #include "iostream" class myclass1 { public: int _AMethod() { return 55; } }; int main() { myclass1* myVariable=(myclass1*)malloc(sizeof(myclass1) * 5); int x = 0; if (x == 0) { //myVariable = (myclass1*)malloc(sizeof(myclass1) * 5); //myVariable = init(); } if (x == 0) { myVariable->_AMethod(); } }
