[Issue 5573] New: Compiler (not linker) should generate an error for missing main()

Running this executable seems to cause an infinite loop you cannot break out of. As Walter said on the newsgroup, it's not possible to solve this in general: The problem is the main() can come from a library, or some other .obj file handed to the compiler that the compiler doesn't look inside. It's a very flexible way to build things, and trying to impose more order on that will surely wind up with complaints from some developers. But, it's only the trivial case that matters. The compiler should generate an error if all files passed to the compiler are .d/.di files, and there is no use of pragma(lib). Error can be something like: No main function, and no .obj or .lib file which could contain one. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

Hello,
void main()

With D v.1 it's all rigth. I guess it's a bug in D v.2

I am using version 2.051 of the dmd compiler.
I am getting this error when I am instantiating a struct array with a
single element inside another class and only if there is the
destructor for the struct is explicitly defined. Is it a known error?
Here is a minimized snippet that gives error:
$ rdmd --main -unittest test.d
Error: this for ~this needs to be type foo not type foo[1u][1u]
Error: this for ~this needs to be type foo not type foo[1u]
// test.d
struct foo {
int foofoo;
~this() { // no error if explicit destructor not
// defined
}
}
class bar {
foo fred;
foo[2][2] foofoo;
foo[1] frop; // this gives error
foo[1][1] fropfrop; // this too
}
unittest {
foo frop;
foo[1][1] fropfrop; // this works

D2 code. map() doesn't modify the input range, so I think this is correct (but
I am not sure if it's correct. A mutable range of immutable items isn't the
same thing as an immutable range):
import std.algorithm;
void main() {
auto u1 = uniq([1]);
auto m1 = map!q{ a }(u1); // OK
const u2 = u1;
auto m2 = map!q{ a }(u2); // Error
}
DMD 2.051 gives:

The following D file:
module main;
void main ()
{
alias extern (C) void function () f;
}
Compiled with dmd -H main.d produces this D interface file:
// D import file generated from 'main.d'
module main;
void main()
{
extern (C) alias void function() f;
}
When compiling the interface file I get the following errors:
main.di(5): basic type expected, not alias
main.di(5): no identifier for declarator int
main.di(5): semicolon expected to close declaration, not 'alias'
This is using dmd 1.066.

-release flags are set.

The following code produces obviously implausible results on 64-bit builds.
result ends up being bigger than 0b111, which is the biggest number that
correct code could generate here. (The correct value, which 32-bit builds
produce, is 3.) This only happens in this test case when -O and -release are
disabled, though I think it still happens with -O and -release enabled in the
program I reduced this bug from.
import std.stdio;
void screwy(string[] data) {
immutable size_t mid = data.length / 2;
immutable uint result = ((cast(uint) (data[0] data[mid])) 2) |
((cast(uint) (data[0] data[$ - 1])) 1) |
(cast(uint) (data[mid] data[$ - 1]));
stderr.writefln(%b, result);
}

auto stuff = [a, a, b];
screwy(stuff);

Sorry, if these issues should be in separate reports, but I did not want to bother everybody with multiple report on these non-urgent changes: 1. The GC invariants in gc.gcx are not thread safe, so I suggest to enable them only with a separate debug identifier or use one of the existing identifiers. 2. _d_arraycopy always prints debug messages, I guess this should also get some debug(PRINTF) condition. 3. _d_framehandler and _d_local_unwind assert with a range violation if they have to unwind more than entry from the handler table. This happens because the struct DHandlerTable uses a place holder array of length 1, but actually expands beyond that.
