bug during compilation with AMS POC 1.0

[johnnie.chan@gmail.com]

I'm getting the following error when trying to compile anything that includes the systemc-ams library:

#include <systemc-ams.h>

int sc_main(int argc, char* argv[])

{ return 0; }

The following error arises:

/tmp/ccWqxyVs.o: In function `sca_util::sca_implementation::sca_matrix_base<double>::~sca_matrix_base()':

/home/johnnie/systemc-ams-1.0/include/scams/impl/util/data_types/sca_matrix_base.h:172: undefined reference to `sca_util::sca_implementation::sca_matrix_base_typeless::~sca_matrix_base_typeless()'

/home/johnnie/systemc-ams-1.0/include/scams/impl/util/data_types/sca_matrix_base.h:172: undefined reference to `sca_util::sca_implementation::sca_matrix_base_typeless::~sca_matrix_base_typeless()'

/tmp/ccWqxyVs.o:(.rodata._ZTIN8sca_util18sca_implementation15sca_matrix_baseIdEE[_ZTIN8sca_util18sca_implementation15sca_matrix_baseIdEE]+0x10): undefined reference to `typeinfo for sca_util::sca_implementation::sca_matrix_base_typeless'

Can anyone help provide insight into what is going on?

Please share the compiler/linker command you have used.

g++ -Wall -DDEBUG -g -I/home/johnnie/systemc-2.3.0/include -I/home/johnnie/systemc-ams-1.0/include -Iinclude/ -L/home/johnnie/systemc-2.3.0/lib-linux64 -L/home/johnnie/systemc-ams-1.0/lib-linux64 -lsystemc-ams -lsystemc test/main.cpp -o a

Use:

g++ test/main.cpp -Wall -DDEBUG -g -I/home/johnnie/systemc-2.3.0/include -I/home/johnnie/systemc-ams-1.0/include -Iinclude/ -L/home/johnnie/systemc-2.3.0/lib-linux64 -L/home/johnnie/systemc-ams-1.0/lib-linux64 -lsystemc-ams -lsystemc -o a

You are not passing the parameters in the right order to the compiler. Recent versions of g++ only include a library if one of its symbols is actually used in one of the preceding object files. Try the following command with the link libraries at the end of the compiler call:

g++ -Wall -DDEBUG -g -o main test/main.cpp -I/home/johnnie/systemc-2.3.0/include -I/home/johnnie/systemc-ams-1.0/include -Iinclude/ -L/home/johnnie/systemc-2.3.0/lib-linux64 -L/home/johnnie/systemc-ams-1.0/lib-linux64 -lsystemc-ams -lsystemc

Sumit, what a coincidence. :-)

Thanks for the fix and the explanation!
