 | The problem list: importC Error: unsigned __int128 not supported importC error: _Builtin_stddef inportC with postgres 16_4 on macOS error no definition of struct `mach_vm_range importC error: alignment value expected, not importC with struct name and function conflict the most important one is int128 support, I am not sure when it will be support or ever will be supported. or there will be workaround. If it takes more than half a year, I will give up. | |||

Does your hardware support it? That message looks like the C preprocessor telling you it's not supported on your machine. | |||

This error is report by dmd or ldc with importC, I guess it cause by d can not handle int128 type. | |||

It is designed to compile C files after they have been first run through the C preprocessor...If the C file has a .c extension, ImportC will run the preprocessor for it automatically." | |||

This reminds me, I should actually mention the exact message so others find that same issue. It took me a while to boil down what the exact problem was. You should also file bug reports for all your issues if they aren't already in bugzilla. That's the only way they will get noticed and fixed. People have various different machines and C compilers, so Walter and whomever else is working on importC can't discover them all. -Steve | |||

 Posted in reply to Dakota | You're in luck! Phobos has an int128 type: https://dlang.org/phobos/std_int128.html The primitives are implemented in core.int128: https://dlang.org/phobos/core_int128.html | |||

May I suggest that the learn subgroup is only for people asking how to do things in D. The best way to report bugs is via our bug reporting system (!): https://issues.dlang.org/ which keeps track of issues until they get resolved, unlike the newsgroups where things scroll away and get forgotten. Remember to tag ImportC issues with the ImportC keyword! | |||

If so, that could maybe go in here: https://github.com/dlang/dmd/blob/master/druntime/src/__importc_builtins.di | |||

Oddly, std.int128 only does signed operations. core.int128 does both signed and unsigned.
