This may be more of a general g++ linking or project question.
I am porting a BeOS multimedia app. It was last compiled probably with BEIDE in
1999 or so. There was no proj or makefile to start with. It has 200++ cpp
files, in 7 folders, which have all now compiled, with warnings. It is
written in an older version of C++ that had lax type checking.
Now I'm working on getting it linked. I'm using make, the compile line looks
like this:
g++ -c TCueChannel.cpp -iquote/<Headers folder> -O0 -fpermissive -Wwrite-srings
-o "objects.x86-gcc4-release/TCueChannel.o"
and the link line looks like this:
gcc -o "objects.x86-gcc4-release/App" <long list of .o files> -L<local lib
folder> -L/boot/develop/lib/x86/gcc4/lib -lbe -lroot -lmedia -ltranslation
-ltracker -lstdc++
The current problem is that the link is not resolving certain 'new' operators.
For instance there are multiple classes for dealing with cues: TMIDICue,
TAudioCue, TTextCue, etc, called from TCueChannel.cpp. Linking gives this error:
TCueChannel.cpp:(.text+0x1ce4): undefined reference to
'TMIDICue::TMIDICue(short, TCueChannel*, BRECT, unsigned long)'
TMIDICue.cpp, TAudioCue.cpp, and TTextCue.cpp are in the media folder. They are
compiled with -fPIC and linked into a shared library, Media.so, which is copied
into <local lib folder>.
The TMIDICue new operator has the correct parameter list in TMIDICue.h. There
is only one reference to the TMIDICue new operator, when I comment it out, the
link error goes away.
Any tips, advice, or pointers appreciated.
Thanks,
Andrew
