c++ - [bug] Linking to a library which depends onto a symbol in the exe
In the soon-to-be-released Pantheios logging library, one of the libraries is
dependent on a symbol that the executable
defines.
This is a no-brainer for all the other supported compilers, but I get the
following from DMC++:
link -DELEXECUTABLE -NOLOGO
.\test_api.debug.obj,"..\..\bin\pantheios.test_api--be.fprintf.dm.debug.exe",,..\..\lib\pantheios.core.dm.debug.lib+..\..\l
ib\pantheios.fe.simple.dm.debug.lib+..\..\lib\pantheios.be.fprintf.dm.debug.lib+..\..\lib\pantheios.bec.fprintf.dm.debug.lib
OPTLINK (R) for Win32 Release 7.50B1
Copyright (C) Digital Mars 1989 - 2001 All Rights Reserved
..\..\lib\pantheios.fe.simple.dm.debug.lib(fe_simple)
Error 42: Symbol Undefined _FE_SIMPLE_PROCESS_IDENTITY
NMAKE : fatal error U1077: 'link' : return code '0x1'
Stop.
Is this a known 'feature' of DMC++/Optlink? Is a fix possible?
Cheers

More on this: If I change the definition in the executable's main source file from extern "C" const char FE_SIMPLE_PROCESS_IDENTITY[] = "test_api"; to extern "C" const char *FE_SIMPLE_PROCESS_IDENTITY = "test_api"; then it works (and DMC++ now appears to fully support Pantheios, which is pretty nice news <g>). This definitely smells like a bug to me, though I concede there may be a rism of minutae in the standard that I've overlooked which backs up DMC++'s behaviour in the matter. Either way, if you can let me know whether DMC++ is correct, or whether it's wrong and when a fix may be forthcoming, it'll help with the Pantheios release.
