Trying to link against ticpp and seeing some weirdness

[GoogleCodeExporter]

I am trying to link again ticpp with a very simple example of a program
(it's not meant to do anything, just a proof of linking with ticpp
successfully). The source of the program is the following:

#define TIXML_USE_TICPP

#include "ticpp.h"

int main()
{
    ticpp::Document xmldoc;

    return 0;
}

To compile, I issued this at my command line: g++ main.cpp -L/usr/lib -lticpp

libticpp.a is definitely located in /usr/lib/

To create the libticpp.a static library, I did a premake with the command
flag of: premake --target gnu

I'm not exactly sure why, but I get linking errors as follows:

try this on your command line, just to be sure you're linking to the file that 
you
think you are.
g++ main.cpp -l/usr/lib/libticpp.a

I tried your suggestion and it didn't do anything different.

Could you run
nm -C libticppd.a > ticpp_symbols.txt
and post ticpp_symbols.txt here?

It is possible to get linker errors similar to those posted by James by 
compiling
ticpp.cpp WITHOUT the macro TIXML_USE_TICPP defined (resulting in a practically 
empty
object file), compiling main.cpp WITH the macro TIXML_USE_TICPP defined, and 
then
trying to link the resulting objects (and the tinyxml-objects).

If not using one of the build scripts, you can use "g++ -DTIXML_USE_TICPP -c 
*.cpp"
to create all the object files correctly and they will link without errors.

hi, 
  i too got the same error while i was trying to do the same thing 
  what james.hodapp did. But it got resolved as i did what mentioned in above comment.

  g++ -DTIXML_USE_TICPP -c *.cpp
  g++ -o xmltest *.o

  Thankyou very much for that.
