Hi all,
I've just installed gdc from Debian Stable (gdc (Debian
6.3.0-18+deb9u1) 6.3.0 20170516), and have been having linker
errors when using writeln.
A minimal nonworking example is as follows: I have a file
library.d which contains the following:
| module library;
|
| import std.stdio;
|
| class Greeter(string s) {
|
| this() { }
|
| void say_hello() {
| writeln("Hello ", s, "!");
| }
| }
I also have a file executable.d which contains the following:
| module executable;
| import library;
|
| int main() {
|
| alias G = Greeter!("James");
| G a = new G();
| a.say_hello();
| return 0;
| }
An attempt to compile it looks as follows:
| $ gdc executable.d -o executable
| /tmp/cc4RjTlb.o:(.data.rel+0x10): undefined reference to
`_D7library12__ModuleInfoZ'
| collect2: error: ld returned 1 exit status
If I remove the import std.stdio and the writeln command from
library.d, then it all works, so I'm clearly not linking
libraries right, but it's not clear to me what to do.
