inline linking problem

[eddy]

Bug report      16. February 2000       by eddy

There is 'bug.tar' attached and includes the files
        makefile  vector.h  vector.cc  bug.cc

(egcs-2.91.66, Intel-Pentium-II)

If you type 'make' the following problem occurs:

>  g++ -c bug.cc -Wall
>  g++ -c vector.cc -Wall
>  g++ -o bug -lg++ -Wall bug.o vector.o
>  bug.o: In function Main':
>  bug.o(.text+0x31): undefined reference to Vector::z(void) const'
>  bug.o(.text+0x45): undefined reference to Vector::y(void) const'
>  bug.o(.text+0x59): undefined reference to Vector::x(void) const'
>  collect2: ld returned 1 exit status
>  make[1]: *** [bug] Error 1
   
but if you uncomment the unused method vector::product() in vector.cc 
then everything is fine.

There must be anything about the 'inline' statements that confuses
the linker in some case of optimisation.
