If multiple files in the same project define RAYMATH_HEADER_ONLY, they might each have duplicate out-of-line definitions of the same functions. By default, raymath.h exposes inline definitions, which instructs the compiler _not_ to generate out-of-line definitons, if out-of-line definitions are required, those of the file defined with RAYLIB_IMPLEMENTATION are used instead. There may be only one such file. In C++ mode, the compiler will select only one out-of-line definition automatically, so no need to define a RAYLIB_IMPLEMENTATION. Unfortunately, we have to remove raymath function declaration from raylib.h as those declarations would lead to duplicate out-of-line definitions which would yield linker errors. This problem didn't exist with GNU89 or C++, because there multiple defintions are ok, but in C99 they aren't. --- examples/models/models_skybox.c | 2 +- src/core.c | 7 +- src/raylib.h | 21 ------ src/raymath.h | 139 ++++++++-------------------------------- 4 files changed, 29 insertions(+), 140 deletions(-) (limited to 'examples/models') diff --git a/examples/models/models_skybox.c b/examples/models/models_skybox.c index 46297e41..9f0d8c17 100644 --- a/examples/models/models_skybox.c +++ b/examples/models/models_skybox.c @@ -62,7 +62,7 @@ int main() Begin3dMode(camera); - DrawModel(skybox, Vector3Zero(), 1.0f, WHITE); + DrawModel(skybox, (Vector3){0, 0, 0}, 1.0f, WHITE); DrawGrid(10, 1.0f); diff --git a/src/core.c b/src/core.c index 137c0b61..0382aacd 100644 --- a/src/core.c +++ b/src/core.c @@ -98,13 +98,12 @@ #define _POSIX_C_SOURCE 199309L // Required for CLOCK_MONOTONIC if compiled with c99 without gnu ext. #endif +#define RAYMATH_IMPLEMENTATION // Define external out-of-line implementation of raymath here +#include "raymath.h" // Required for: Vector3 and Matrix functions + #include "rlgl.h" // raylib OpenGL abstraction layer to OpenGL 1.1, 3.3+ or ES2 #include "utils.h" // Required for: fopen() Android mapping -#define RAYMATH_IMPLEMENTATION // Use raymath as a header-only library (includes implementation) -#define RAYMATH_EXTERN_INLINE // Compile raymath functions as static inline (remember, it's a compiler hint) -#include "raymath.h" // Required for: Vector3 and Matrix functions - #if defined(SUPPORT_GESTURES_SYSTEM) #define GESTURES_IMPLEMENTATION #include "gestures.h" // Gestures detection functionality diff --git a/src/raylib.h b/src/raylib.h index a740e234..66598b27 100644 --- a/src/raylib.h +++ b/src/raylib.h @@ -338,14 +338,6 @@ typedef struct Matrix { float m3, m7, m11, m15; } Matrix; -typedef struct Float3 { - float f[3]; -} Float3; - -typedef struct Float16 { - float f[16]; -} Float16; - // Color type, RGBA (32bit) typedef struct Color { unsigned char r; @@ -750,19 +742,6 @@ RLAPI Vector3 ColorToHSV(Color color); // Returns HSV RLAPI Color GetColor(int hexValue); // Returns a Color struct from hexadecimal value RLAPI Color Fade(Color color, float alpha); // Color fade-in or fade-out, alpha goes from 0.0f to 1.0f -// Math useful functions (available from raymath.h) -RLAPI Vector3 Vector3Zero(void); // Vector with components value 0.0f -RLAPI Vector3 Vector3One(void); // Vector with components value 1.0f -RLAPI Matrix MatrixIdentity(void); // Returns identity matrix -#ifndef Vector3ToFloat -#define Vector3ToFloat(vec) (Vector3ToFloat_(vec).f) // Returns Vector3 as float array -RLAPI Float3 Vector3ToFloat_(Vector3 vec); // don't use, use above -#endif -#ifndef MatrixToFloat -#define MatrixToFloat(mat) (MatrixToFloat_(mat).f) // Returns Matrix as float array -RLAPI Float16 MatrixToFloat_(Matrix mat); // don't use, use above -#endif - // Misc. functions RLAPI void ShowLogo(void); // Activate raylib logo at startup (can be done with flags) RLAPI void SetConfigFlags(unsigned char flags); // Setup window configuration flags (view FLAGS) diff --git a/src/raymath.h b/src/raymath.h index 0eb010f1..a781ec80 100644 --- a/src/raymath.h +++ b/src/raymath.h @@ -9,8 +9,9 @@ * If not defined, the library is in header only mode and can be included in other headers * or source files without problems.

If multiple files in the same project define RAYMATH_HEADER_ONLY, they might each have duplicate out-of-line definitions of the same functions. By default, raymath.h exposes inline definitions, which instructs the compiler _not_ to generate out-of-line definitons, if out-of-line definitions are required, those of the file defined with RAYLIB_IMPLEMENTATION are used instead. There may be only one such file. In C++ mode, the compiler will select only one out-of-line definition automatically, so no need to define a RAYLIB_IMPLEMENTATION. Unfortunately, we have to remove raymath function declaration from raylib.h as those declarations would lead to duplicate out-of-line definitions which would yield linker errors. This problem didn't exist with GNU89 or C++, because there multiple defintions are ok, but in C99 they aren't. --- examples/models/models_skybox.c | 2 +- src/core.c | 7 +- src/raylib.h | 21 ------ src/raymath.h | 139 ++++++++-------------------------------- 4 files changed, 29 insertions(+), 140 deletions(-) (limited to 'examples/models') diff --git a/examples/models/models_skybox.c b/examples/models/models_skybox.c index 46297e41..9f0d8c17 100644 --- a/examples/models/models_skybox.c +++ b/examples/models/models_skybox.c @@ -62,7 +62,7 @@ int main() Begin3dMode(camera); - DrawModel(skybox, Vector3Zero(), 1.0f, WHITE); + DrawModel(skybox, (Vector3){0, 0, 0}, 1.0f, WHITE); DrawGrid(10, 1.0f); diff --git a/src/core.c b/src/core.c index 137c0b61..0382aacd 100644 --- a/src/core.c +++ b/src/core.c @@ -98,13 +98,12 @@ #define _POSIX_C_SOURCE 199309L // Required for CLOCK_MONOTONIC if compiled with c99 without gnu ext. #endif +#define RAYMATH_IMPLEMENTATION // Define external out-of-line implementation of raymath here +#include "raymath.h" // Required for: Vector3 and Matrix functions + #include "rlgl.h" // raylib OpenGL abstraction layer to OpenGL 1.1, 3.3+ or ES2 #include "utils.h" // Required for: fopen() Android mapping -#define RAYMATH_IMPLEMENTATION // Use raymath as a header-only library (includes implementation) -#define RAYMATH_EXTERN_INLINE // Compile raymath functions as static inline (remember, it's a compiler hint) -#include "raymath.h" // Required for: Vector3 and Matrix functions - #if defined(SUPPORT_GESTURES_SYSTEM) #define GESTURES_IMPLEMENTATION #include "gestures.h" // Gestures detection functionality diff --git a/src/raylib.h b/src/raylib.h index a740e234..66598b27 100644 --- a/src/raylib.h +++ b/src/raylib.h @@ -338,14 +338,6 @@ typedef struct Matrix { float m3, m7, m11, m15; } Matrix; -typedef struct Float3 { - float f[3]; -} Float3; - -typedef struct Float16 { - float f[16]; -} Float16; - // Color type, RGBA (32bit) typedef struct Color { unsigned char r; @@ -750,19 +742,6 @@ RLAPI Vector3 ColorToHSV(Color color); // Returns HSV RLAPI Color GetColor(int hexValue); // Returns a Color struct from hexadecimal value RLAPI Color Fade(Color color, float alpha); // Color fade-in or fade-out, alpha goes from 0.0f to 1.0f -// Math useful functions (available from raymath.h) -RLAPI Vector3 Vector3Zero(void); // Vector with components value 0.0f -RLAPI Vector3 Vector3One(void); // Vector with components value 1.0f -RLAPI Matrix MatrixIdentity(void); // Returns identity matrix -#ifndef Vector3ToFloat -#define Vector3ToFloat(vec) (Vector3ToFloat_(vec).f) // Returns Vector3 as float array -RLAPI Float3 Vector3ToFloat_(Vector3 vec); // don't use, use above -#endif -#ifndef MatrixToFloat -#define MatrixToFloat(mat) (MatrixToFloat_(mat).f) // Returns Matrix as float array -RLAPI Float16 MatrixToFloat_(Matrix mat); // don't use, use above -#endif - // Misc. functions RLAPI void ShowLogo(void); // Activate raylib logo at startup (can be done with flags) RLAPI void SetConfigFlags(unsigned char flags); // Setup window configuration flags (view FLAGS) diff --git a/src/raymath.h b/src/raymath.h index 0eb010f1..a781ec80 100644 --- a/src/raymath.h +++ b/src/raymath.h @@ -9,8 +9,9 @@ * If not defined, the library is in header only mode and can be included in other headers * or source files without problems.
