That is if you know about this issue. Very few people do. At some point C23 may become a default version of C in some compilers and someone who has been building code without specifying what version of C they use, will silently get a bug. T

You are right it is bad to use typeless variables, and its also bad to use auto in C23 to infer type. So this code should never be written, but its still bad to break existing code.
63.
by quelsolaar 3y ago
You cant make a compiler diagnostic, because it was valid before and after C23, the code just means different things. In fact just using auto without a type was bad practice in earlier versions, now it can be considered a feature, so its le
64.

Yes the use of auto is rare, and should not be used in the first place. Still i don't like silently breaking old code. You cant just do a search and replace. This is valid: auto float f; so a search and replace would break that code.

You are right. void pointers can convert to any pointer type in C. That's why you don't need to cast malloc in C.

Because it changes the meaning of existing code. That's a big no-no.

A few things to note and out this. Yes feel free to enable -Werror, but warnings are implementation specific, so there is no way to write portable C code that is warning free. A compiler can issue a warning for anything, like you using a co

And its broken! Consider: auto i = 0.0; i is a double in C23 but an int in earlier version. Please don't use C23.

I have no problem putting ifdefs around my platform specific code.

No, Bercause MakeMake cant know what defines are made by the compiler on the system. MakeMake may not even run on the same system as the resulting makefile will be used on. This means that all source code files has to be compilable on all p

It builds a Android APK with one line of comand line on a fresh install linux to begin with (Thanks to Felix) thats pretty cool. Id say the main use case is to move dependencies from a project file to the actiual C files that have the depen

by quelsolaar 3y ago
Because Cmake requires a configuration file for each project. With makemake i can with a single command line build a new project without any configuration needed. Its one less thing to maintain.

Here is the fundamental problem it solves for me: my code in 99% pure C code without dependencies. Then i have a few wrappers for platform specific stuff. I have many many projects that use the same wrappers. Make files store both what file

by quelsolaar 3y ago
Yes. I had an early implementation that did look for any function declarations, but using extern made it more robust, and enforces the use of extern, something i think helps with clarity.

As a graphics programmer i think its good to have a well rounded idea about how graphics works. Here are some things I would expect a good graphics programmer to know, beyond just programming and an API: -Rotation view and projection matric

C is a perfectly good alternative to C++ for Graphics programming. OpenGL and Vulcan are C APIs and DirectX has a C wrapper. Some games like Call of duty are written in C, but C++ is more common.

Being a graphics programmer is a pretty well defined category of programmers. A lot of the things you mentioned aren't graphics programming like Rig, Texture or Model, and a graphics programmer is expected to be able to run the gamut o

Sure we could all use more positive visions for the future, but... The most immediate need we have to Taiwan is TSMC. Without them Nvidia, AMD and Apple are effectively dead, along with any car company, and a good deal of the products and s

Generally these are good, but in practice #1 doesn't hold. When you start out you need to have a _theory_ about what will be you bottleneck. A lot of times you cant implement XYZ, and then measure what was slow and fix that. X, Y, and

You can declare flexible array member strings with literals like this: #define DECLARE_STRING(variable_name, string) struct{size_t allocated; size_t used; char string[sizeof(c_string)];} variable_name ## internal = {.allocated = sizeof(c_st
