I am compiling chapel with llvm and I am getting linker ‘undefined reference’ errors. I am linking to a library in a local directory so I provide the library and library path on the chapel command line. During linking, these values are placed at the beginning of the generated command line which is causing the error. Here is the command line I’m using and the generated command line for the linking, respectively:
My command line: /data1/projects/prog-guided-reliability/chapel-1.8.0/bin/linux64/chpl -I. -I/home/tmj/fftw-3.3.3/include --print-commands --savec gen_c --llvm bitmap.h fft.h glob_wrapper.h read_glyph.h ssca3.h sys_util.h write_image.h main.chpl createBitmap.o fft.o glob_wrapper.o read_glyph.o sys_util.o write_image.o -o ssca3 -L/home/tmj/fftw-3.3.3/lib -lfftw3 Linker command line: /data1/projects/prog-guided-reliability/chapel-1.8.0/third-party/llvm/install/linux64-gnu/bin/clang++ -pthread -L/home/tmj/fftw-3.3.3/lib -lfftw3 gen_c/chpl__module.bc /data1/projects/prog-guided-reliability/chapel-1.8.0/lib/linux64.gnu.loc-flat.tasks-fifo.pthreads.tmr-generic.mem-default.atomics-intrinsics.gmp.re-none.wide-struct.fs-none/main.o -o gen_c/ssca3.tmp createBitmap.o fft.o glob_wrapper.o read_glyph.o sys_util.o write_image.o -L/data1/projects/prog-guided-reliability/chapel-1.8.0/third-party/gmp/install/linux64-gnu/lib -Wl,-rpath=/data1/projects/prog-guided-reliability/chapel-1.8.0/third-party/gmp/install/linux64-gnu/lib -L/data1/projects/prog-guided-reliability/chapel-1.8.0/lib/linux64.gnu.loc-flat.tasks-fifo.pthreads.tmr-generic.mem-default.atomics-intrinsics.gmp.re-none.wide-struct.fs-none -lchpl -lm -lpthread -lgmp When I execute the generated command manually with the library (-lfftw3) at the end of the command line, there is no error. Is there any way for me to control the position of the linker arguments from the original command line?
