With CMake, it’s generally recommended to do an “out of source” build. Create your CMakeLists.txt in the root of your project. Then from the root of your project: And for Debug (again from the root of your project): Release / Debug will add the appropriate flags for your compiler. There are also RelWithDebInfo and MinSizeRel build configurations. You can modify/add to the flags by specifying a toolchain file in … Read more
In C89 standard, initializer list must be compile time constants expressions, hence the warnings. However in C99 it is supported. In C89, you can do:
This is illegal in C. Initializer lists must be constant compile time expressions. Do the following instead:
In C int foo() and int foo(void) are different functions. int foo() accepts an arbitrary number of arguments, while int foo(void) accepts 0 arguments. In C++ they mean the same thing. I suggest that you use void consistently when you mean no arguments. If you have a variable a, extern int a; is a way to tell the compiler that a is a symbol that might be present in a … Read more
I faced this same problem after installing xcode; All I had to do was run gcc. This then asked me to accept the xcode license. After, it just worked fine. Hope this helps someone.
The <malloc.h> header is deprecated (and quite Linux specific, on which it defines non-standard functions like mallinfo(3)). Use <stdlib.h> instead if you simply need malloc(3) and related standard functions (e.g. free, calloc, realloc ….). Notice that <stdlib.h> is defined by C89 (and later) standards, but not <malloc.h> Look into /usr/include/malloc.h you’ll find there some non-standard functions (e.g. malloc_stats(3), etc…) – in addition of malloc…. And gcc don’t link header files, but libraries. Read Levine’s book about linkers & loaders for more. … Read more
The reason the base class is abstract is this pure virtual function: The derived class DisablePairCollision attempts to define that function, but it does not do it correctly: As you can see, some of the arguments have different types. E.g. colObj0 is of type const btCollisionObject*, but it should be of type const btCollisionObjectWrapper*. Therefore, … Read more
points_read is most likely out of bounds, you’re writing past (or before) the memory you allocated for amplitudes.
This rule is wrong. It says to create a file named producer.o (with -o producer.o), but you want to create a file named main. Please excuse the shouting, but ALWAYS USE $@ TO REFERENCE THE TARGET: As Shahbaz rightly points out, the gmake professionals would also use $^ which expands to all the prerequisites in … Read more
Those error messages or just mean that CMake was unable to find your C/CXX compiler to compile a simple test program (one of the first things CMake tries while detecting your build environment). The steps to find your problem are dependent on the build environment you want to generate. The following tutorials are a collection … Read more
