Subject: [PATCH] force position independent code
|
|
|
|
Without this option, programs building for arm64 or x86-64 will fail when
|
|
attempting to link to the built libraries with the following (abbreviated)
|
|
error:
|
|
|
|
"relocation against `.rodata' can not be used when making a shared object;
|
|
recompile with -fPIC."
|
|
|
|
Because libabseil-cpp builds static libraries, it is better to set the
|
|
POSITION_INDEPENDENT_CODE to ON instead of forcing fPIC, as forcing fPIC may
|
|
cause relocation errors when shared libraries link against the built static
|
|
libraries.
