Hello!

After a couple of months, I wanted to write a small programm using DMD 1.028 and Tango 0.99.6 (Jeff) on Linux. Both were installed using the install script from the DWT Page ( http://www.dsource.org/projects/dwt/wiki/SetupLinux ). I use CodeBlocks 8,02 as my IDE.

Unfortunately my code fails to compile as soon as I try to use tango.io.File.

This sample code compiles fine:

module test;

import tango.io.Console;
import tango.io.File;

int main()
{
    File f=null;

    Cout ("Test of Tango file functions").newline;

    //f=File("text.txt");

    return 0;
}

But as soon as I uncomment the line "f=File("text.txt");", I get the
following message when linking:

Compiling: test.d
Linking console executable: bin/Debug/test-tango
/usr/lib/gcc/i486-linux-gnu/4.2.4/../../../../lib/libtango-user-dmd.a(tango.time.Time.o)

undefined reference to `_D10TypeInfo_l6__initZ'
collect2: ld returned 1 exit status
Process terminated with status 1 (0 minutes, 0 seconds)
0 errors, 0 warnings

I'm linking with libpthread.a, libm.a, libtango-base-dmd.a and libtango-user-dmd.a. Am I missing another library?

Best regards and thanks in advance,
Timo

Without me having seen that exact error, it sounds like one of the issues with anonymous stuff in that particular range of DMD compilers. If possible, you should upgrade to DMD 1.033 (or alternatively downgrade to DMD 1.027).

The script installs a copy of tango/dsss and other stuff into the installation directory. There is also a shell script called dsss.sh which serves as starter for dsss, ensuring it uses the correct paths.
Your messages now looks like you did not use that shell script and it is now using another version of libtango-user-dmd.a as the one from the tango directory.

Thanks, Frank and Lars. In the meantime I have installed DMD 1.033 (as Lars suggested) compiled Tango from source. It works now.

Best regards,
Timo
