Experimental Physics and Industrial Control System
Hi All,
Has anyone built a 3.14 application for a mips target? I'm
building this from solaris with tornado 2.0. This thread
extends from last weeks subject "Undefined symbols
R3.14.6"... thanks for the help so far!
I can't get a simple "bare-bones" CA client app to load on a
mips board. This works fine on the PPC architecture. The
test I came up with just links in acctst.o and
vxComLibrary.o from base.
On the mips build I get an undefined symbol in the final
munch file that *very* closely matches a defined symbol save
for the prepended underscore :
>nmmips test.munch | grep libCom
000b76b0 T
_GLOBAL_$I$.._.._.._src_libCom_cxxTemplates_epicsSingletonMutex.cpp
U
__GLOBAL_$I$.._.._.._src_libCom_cxxTemplates_epicsSingletonMutex.cpp
Whereas on the ppc604_long build this is full resolved:
> nmppc test.munch | grep libCom
000e20f8 T
_GLOBAL_$I$_________src_libCom_cxxTemplates_epicsSingletonMutex_cpp
I noticed the dots after "_GLOBAL_$I$". If munch.pl sees any
dots in the symbol name it tags the symbol as a function
call with an "__asm__" attribute. This ends up in
test_ctdt.c as:
void
_GLOBAL_$I$$$_$$_$$_src_libCom_cxxTemplates_epicsSingletonMutex$cpp
() __asm__
("__GLOBAL_$I$.._.._.._src_libCom_cxxTemplates_epicsSingletonMutex.cpp");
Not sure if that's correct.
There must be an incorrect linker flag or something. Thanks
for any help! I've included some build info below.
