Linking problem with tango.stdc.stringz

Posted: 02/24/09 19:51:44 Hello. I tried a simple script: {{{module test; import tango.io.Console; import tango.stdc.stringz; int main( char[][] args ) { toStringz( "test" ); return 0; } }}} There is no problem about the io.Console. But as soon I add the stdc.stringz I get the following problems while calling: gdc test.d -o test -fversion=Posix -fversion=Tango -lgtango This is the error I get: /tmp/ccg4V1fL.o: In function `_Dmain': test.d:(.text+0x55): undefined reference to `_D5tango4stdc7stringz9toStringzFAaZPa' Does someone has an idea? I already had this problem on Windows and Linux.

But default things like io.Console or io.FileConduit? don't have any problems. module temp; import tango.util.Convert; int main( char[][] args ) { to!(char[])(123); return 0; } Gives the error: ./_temp.o:(.data+0x60): undefined reference to `_D5tango4util7Convert12ModuleInfoZ' ./_temp.o: In function `_D5tango4util7Convert18T8toStringTAaTiZ8toStringFiZAa': temp.d:(.text._D5tango4util7Convert18T8toStringTAaTiZ8toStringFiZAa[_D5tango4util7Convert18T8toStringTAaTiZ8toStringFiZAa]+0x1c): undefined reference to `_D5tango4text7convert7Integer8toStringFlE5tango4text7convert7Integer5StyleE5tango4text7convert7Integer5FlagsZAa' module temp; import tango.text.Text; int main( char[][] args ) { auto dst = new Text!(char); foreach (element; Util.patterns ("all cows eat grass", "eat", "chew")) dst.append (element); return 0; } This works module temp; import tango.text.convert.Integer; int main( char[][] args ) { toString( 12 ); return 0; } Does not work: ./_temp.o: In function `_Dmain': temp.d:(.text+0x20): undefined reference to `_D5tango4text7convert7Integer8toStringFlE5tango4text7convert7Integer5StyleE5tango4text7convert7Integer5FlagsZAa'

I only copied it to the /usr/include/d/tango folders :( But now everything works fine :) But thanks for your help. :)
