Steps to reproduce:

$ tar xzf s7.tar.gz
$ cd s7
$ dmd s7.c

BTW, LDC2 has the same error, because it share the same front end with DMD.

My Linux machine apparently has a different cmathcalls.h file than yours. If you could isolate the source code that causes this problem, that would be most helpful.

I can upload the generated s7.i on my machine, do you think it will helpful?

s7.i.gz attached. dmd s7.i shows the same error.

s7.i.gz attached. dmd s7.i shows the same error.

Thank you. What would be even more helpful would be to cut it down to just what produces the error!

Haha, I made it: 2 lines!


$ cat s2.i
extern _Complex _Float32 cacosf32 (_Complex _Float32 __z) __attribute__
((__nothrow__ , __leaf__)); extern _Complex _Float32 __cacosf32 (_Complex
_Float32 __z) __attribute__ ((__nothrow__ , __leaf__));
extern _Complex _Float32x cacosf32x (_Complex _Float32x __z) __attribute__
((__nothrow__ , __leaf__)); extern _Complex _Float32x __cacosf32x (_Complex
_Float32x __z) __attribute__ ((__nothrow__ , __leaf__));


$ gcc -c s2.i  # ok
$ dmd s2.i
s2.i(1): Error: illegal type combination
s2.i(1): Error: missing comma or semicolon after declaration of `_Float32`,
found `cacosf32` instead
s2.i(1): Error: illegal type combination
s2.i(1): Error: missing comma or semicolon after declaration of `_Float32`,
found `__cacosf32` instead
s2.i(2): Error: illegal type combination
s2.i(2): Error: missing comma or semicolon after declaration of `_Float32x`,
found `cacosf32x` instead
s2.i(2): Error: illegal type combination
s2.i(2): Error: missing comma or semicolon after declaration of `_Float32x`,
found `__cacosf32x` instead


I will attach s2.i.

But if you fix s2.i, pls also try if the fix works for s7.i.gz.

The two lines:

extern _Complex _Float32 cacosf32 (_Complex _Float32 __z) __attribute__
((__nothrow__ , __leaf__)); extern _Complex _Float32 __cacosf32 (_Complex
_Float32 __z) __attribute__ ((__nothrow__ , __leaf__));

extern _Complex _Float32x cacosf32x (_Complex _Float32x __z) __attribute__
((__nothrow__ , __leaf__)); extern _Complex _Float32x __cacosf32x (_Complex
_Float32x __z) __attribute__ ((__nothrow__ , __leaf__));

Thanks, this reproduces the problem.

It compiles without error if `Float32` is replaced with `float`.
