Hello! I am happily using GCC version 7.0.1 20170411 (experimental) (GCC) on ubuntu 5.4.0 for offloading C code to my Palit Geforce GXT 1070 graphics card containing 1920 CUDA cores running at max. 1683 MHz. ;) How to offload a C library that I have installed myself ? I try to offload the ta_lib library. The library files are in /usr/lib: libta_lib.a libta_lib.so libta_lib.so.0 The headers are in /usr/include: ta_abstract.h ta_common.h ta_defs.h ta_func.h ta_libc.h The CPU-only code using the library works great. I compile like this: gcc test3.c -o test3.x -lm -lconfig -lta_lib Offloading without the library also works great: gcc test3.c -fopenacc -foffload=nvptx-none -foffload="-O3" -o test3.x -lm -lconfig Is is possible to offload the library? Can I put multiple -l -L and -I options within the -foffload argument? or use multiple -foffload options? something like this? gcc test3.c -fopenacc -foffload=nvptx-none -foffload="-O3 -lta_lib / -L/usr/local/lib" -O3 -o test3.x -lm -lconfig -lta_lib -I/usr/local/include/ta-lib/ -L/usr/local/lib or this? gcc test3.c -fopenacc -foffload=nvptx-none -foffload=-L/usr/local/lib -foffload=-lta_lib -foffload=-I/usr/local/include/ta-lib -O2 -o test3.x -lm -lconfig -lta_lib -I/usr/local/include/ta-lib/ -L/usr/local/lib -v I keep on getting an unresolved symbol error TA_S_RSI It is in the static archive: nm /usr/lib/libta_lib.a | grep RSI gives: ta_RSI.o: 0000000000000050 T TA_RSI 0000000000000000 T TA_RSI_Lookback 0000000000000480 T TA_S_RSI I have the library both in /usr/lib and /usr/local/lib, and the includes in /usr/local/include and /usr/include. thanks a lot.
