It looks like Microsoft has deprecated lots of calls which use buffers to improve code security. However, the solutions they’re providing aren’t portable. Anyway, if you aren’t interested in using the secure version of their calls (like fopen_s), you need to place a definition of _CRT_SECURE_NO_DEPRECATE before your included header files. For example: #define _CRT_SECURE_NO_DEPRECATE … Read more

This particular issue is caused by specifying a dependency to a lib file that had spaces in its path. The path needs to be surrounded by quotes for the project to compile correctly. On the Configuration Properties -> Linker -> Input tab of the project’s properties, there is an Additional Dependencies property. This issue was … Read more
There are several approaches: You can normally see assembly code while debugging C++ in visual studio (and eclipse too). For this in Visual Studio put a breakpoint on code in question and when debugger hits it rigth click and find “Go To Assembly” ( or press CTRL+ALT+D ) Second approach is to generate assembly listings … Read more

As of CMake 3.1+ the developers strongly discourage users from using file(GLOB or file(GLOB_RECURSE to collect lists of source files. Note: We do not recommend using GLOB to collect a list of source files from your source tree. If no CMakeLists.txt file changes when a source is added or removed then the generated build system … Read more
