Re: Compile error "recompile with -fPIC"

[shilparavindra03]

Hi,
Even am getting similar kind of error but the difference is am executing in 
CentOS 7.5. and am not able to find in which make file i need to add -fPIC 
option because tools/makefile is not present. 

ERROR obtained :

g++   -shared -fPIC -o Build/libNSCGBI.so dllmain.o NSCGBI.o
/usr/bin/ld: NSCGBI.o: relocation R_X86_64_32 against `.rodata' can not be used 
when making a shared object; recompile with -fPIC
/usr/bin/ld: final link failed: Nonrepresentable section on output
collect2: error: ld returned 1 exit status

Can any one help me regarding this ??

You can revert that local change and "git am"

Re: Compile error "recompile with -fPIC"

[mike]

Henning,
thank you for the great support.

Adding -fPIC to tools/Makefile

KBUILD_CFLAGS := -fPIC -g -O3 -DLIBEXECDIR=\"$(libexecdir)\" \
-Wall -Wextra -Wmissing-declarations -Wmissing-prototypes -Werror \
-DJAILHOUSE_VERSION=\"$(shell cat $(src)/../VERSION)\" $(EXTRA_CFLAGS)

did the job.
Regards,
mike

Well because your default is 6 anyways, try 5 or 4.9 in that case. I
will try to reproduce it. gcc-6.3 works on debian just fine. Just to
make sure you are on x86_64?

Maybe try an older compiler, which version is your gcc? You can
probably install something older and compile jailhouse with that
i.e
"make CC=gcc-6"
