[cfe-users] clang++ not able to link libraries crtbegin.o

[Srinivasa Rao Ragolu via cfe-users]

Hi All,

I am new to clang. I have taken meta-clang and ported to my yocto project
for aarch64 with below commands. And building nodejs-.4.4.4 using clang++


TOOLCHAIN_pn-nodejs = "clang"
DEPENDS_append_pn-nodejs = " clang-cross-aarch64 "

added below line to nodejs recipe

TOOLCHAIN = "clang"

Compilation is going fine but could see below linking error

cannot find crtbegin.o: No such file or directory*


But my project staging directory contains crtbegin.o

srinivas at srinivas:~/clang-project/emgw-project/broadcom-ns2-emgw-3.10-1.4-project$
find tmp/sysroots/ | grep crtbegin.o
tmp/sysroots/broadcom-ns2-emgw/usr/lib64/gcc/aarch64-montavista-linux/4.7.0/crtbegin.o
tmp/sysroots/broadcom-ns2-emgw/usr/lib64/gcc/aarch64-montavista-linux/4.7.0/ilp32/crtbegin.o


Please help to resolving this issue

Thanks,
Srinivas.
