Hi,

I have a project which will build a shared library rather than a executable. I want to use fastCV as cv::remap in my code is very time-consuming.

So I added fastcv to buid my .so but some errer happened during compiling.

The error is as following:

fcvImageSegmentationRegionGrowR_' which may bind externally can not be used when making a shared object; recompile with -fPIC /home/worker/Sof/fastcv-1.7.1/lib/64-bit/libfastcv.a(libfastcv_la-fastcv.o): In function
uRNull()': /usr/src/debug/fastcv-noship/git-r0/fastcv-noship/src/common/fastcv.cpp:1723:(.text+0x0): dangerous relocation: unsupported relocation

It seems that libfastcv.a is not build with "-fPIC" so libfastcv.a can not be used to build a shared library. If so, will Qualcomm release a version build with -fPIC?

Thanks in advance!
