thank you for your investigation and for your detailed error report.
Does someone of the eCos folks know a better way to solve the
__cxa_pure_virtual issue or should we go with Sergei's proposal
-Wl,--defsym -Wl,__cxa_pure_virtual=0
CYGPKG_INFRA is supposed to provide a replacement implementation of this
function. Did you try adding your own implementation of
__cxxabiv1::__cxa_pure_virtual() as discussed on the ecos-devel list?
Hi Jonh,
Are such implementations (in pure.cxx) useful? I'm looking on linker
group
GROUP(libtarget.a libgcc.a libsupc++.a)
$ nm install/lib/libtarget.a | grep __cxa_pure_virtual
00000000 T __cxa_pure_virtual
Okay it came there from infra_pure.o. Is it right? But, there is next
implementation in libsupc++.a.
$ nm i386-elf/i386-elf/lib/libsupc++.a 2>/dev/null | grep __cxa_pure_virtual
U __cxa_pure_virtual
00000000 T __cxa_pure_virtual
