Just curious, if I do need complex how hard is it to implement it? I
presume if the user wants to use LAPACKE or similar numerical library
they will run into similar problems
Any pointers would be much appreciated.
Many thanks

Re: [Tinycc-devel] Compilation error while including LAPACKE
After your last message I've tried defining "_Complex" to empty and for
the simple test it compiled, probably if you are not using complex this
trick could work:
=
#include
#define _Complex //make it e noop
#include
int main() {
printf("Hello World!\n");
return 0;
}
Output:
../tcc cmath.c
>Exit code: 0
./a.out
>./a.out
Hello World!
>Exit code: 0

If complex types are not supported are there known work-arounds other
than "dont use them"?

[Tinycc-devel] Compilation error while including LAPACKE
Hello all,
Trying to use tinycc to compile a code base that uses LAPACKE. But as
soon as I include the header I run into problems, I get the following
error:
```
In file included from main.c:1:
In file included from /usr/include/lapacke.h:37:
In file included from /usr/include/lapack.h:55:
In file included from /usr/include/complex.h:106:
/usr/include/x86_64-linux-gnu/bits/cmathcalls.h:55: error: ';'
expected (got "cacos")
```
where main.c is:
```
#include
#include
int main() {
printf("Hello World!\n");
return 0;
}
```
compiled using `tcc main.c -o a.out`
Any help would be appreciated, thanks!
Chris
