static-lib example executable print blank result compiled by cl

[LukyGuyLucky]

With https://github.com/c3lang/c3c/tree/master/resources/examples/staticlib-test ,the executable of test.c3 print proper result:

In adder
Print foo: Foo[1]
5

while the executable test.exe of test.c compiled by VS Studio 2022 cl just print blank.

I don't know what I did wrong.

c3c static-lib add.c3
c3c compile-run test.c3 -l add.lib
cl test.c add.lib //under x64 Native Tools Command Prompt

Win10 64 bit ,MS Visual Studio 2022,the most updated c3c (as of today).

Does the dynlib test work?

[LukyGuyLucky]

Yes,just tried.both c3 and c works.

[lerno]

Static libraries is the tricky part. Can you see if you add an @init method in the static library if that one is called when you use C?

Like

import libc;
fn void startuptest() @init
{
  libc::puts("Hello from startuptest");
}

[LukyGuyLucky]

No,it is the same in c; In c3 test Hello from startuptest printed as well.

What if you change this:

int main()
{
	printf("%d\n", adder(1, 4));
	return 0;
}

To

int main()
{
  puts("Before");
  printf("%d\n", adder(1, 4));
  puts("After");
  return 0;
}

What is printed?

[LukyGuyLucky]

Things are weird.
The first thing I did this morning is just to recompile test.c according to your most recent tips ---add puts("Before") and puts("After") and then re-run the example,so I got Before printed.Yes,onlyBefore.

After that I deleted all generated files and I tried to rebuilt the add.lib from scratch.Now when I tried to rebuild test.c I got a compiler complaints which means Unresolved external symbols SymInitialize,SymCleanup ,etc .

for test.c3,everything is ok.

Maybe you need to manually link to some of those missing libraries. For the above you would need to link with Dbghelp.lib

[LukyGuyLucky]

with dbghelp.lib now test.c works as well.

[lerno]

So it prints before / after and the part in between?

[LukyGuyLucky]

Yes,all printed as expected.

Add module initializes here.
Before
In adder
Print foo: Foo[1]
5
After
Add module finalizes here.

[LukyGuyLucky]

BTW,dgbhelp.lib is needed here which is not so common as expected.
