unknown type name 'uint32_t'

[trikko]

t.h:

#include <stdint.h>
uint32_t test;

t.dpp:

#include "t.h"

void main()
{
}

> d++ t.dpp

output:

Error: Error parsing '/tmp/libclangYrt380':
./t.h:3:1: error: unknown type name 'uint32_t'
Program exited with code 1

linux + libclang10 + dpp 0.4.9

Including inttypes.h makes things even worse.

I can't reproduce this. The error message indicates that libclang can't parse the code you wrote, which is more than odd.

I'll add this worked fine for me, I compiled with clan 12.0.0 (and llvm), and latest dmd/ldc (2.99.1/1.29.0 or so).

I have a similar issue with the following instructions:

$ ls
issue307.dpp
$ cat issue307.dpp
#include <stdint.h>
uint32_t test;

void main(){}
$ docker run --rm -it -v $PWD:/workdir -w /workdir ubuntu:22.04 bash

I had the similar issue when I linked clang-14 to /usr/bin/clang in ubuntu 22.04. When I changed it to clang-12, everything worked fine.
