undefined reference to `parse_opts'

Hi all,
I am trying to write my own magma file. I pass the following through the terminal:
Code: Select all
nvcc AA_TriEigenSolve.cpp libmagma.so -o AA_TriEigenSolve -I/usr/local/magma/include -lgfortran -lm -lcublas -DHAVE_CUBLAS -DNOCHANGE -lstdc++ -ldl -L/usr/lib/atlas-base
And get these errors:
Code: Select all
AA_TriEigenSolve.cpp:(.text+0x91): undefined reference to `dlamch'
AA_TriEigenSolve.cpp:(.text+0xb4): undefined reference to `parse_opts'
AA_TriEigenSolve.cpp:(.text+0xce): undefined reference to `dlamch'
AA_TriEigenSolve.cpp:(.text+0xf5): undefined reference to `dlamch'
collect2: ld returned 1 exit status
Can anybody help?

Okay have gotten past the previous error. My new input is:
Code: Select all
nvcc AA_TriEigenSolve.cpp testing_util.cpp libmagma.so /usr/lib/atlas-base/liblapack_atlas.a -o AA_TriEigenSolve -I/usr/local/magma/include -lgfortran -lm -lcublas -DHAVE_CUBLAS -DNOCHANGE -lstdc++
And I am getting a new error of:
Code: Select all
/usr/bin/ld: libmagma.so: undefined reference to symbol 'xerbla_'
/usr/bin/ld: note: 'xerbla_' is defined in DSO /usr/lib/liblapack.so.3gf so try adding it to the linker command line
/usr/lib/liblapack.so.3gf: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
Any help is appriciated

Okay I'm down to this
Code: Select all
nvcc AA_TriEigenSolve.cpp testing_util.cpp libmagma.so /usr/lib/lapack/liblapack.a /usr/lib/openblas-base/libopenblas.a /usr/lib/atlas-base/liblapack_atlas.a -o AA_TriEigenSolve -I/usr/local/magma/include -lgfortran -lm -lcublas -DHAVE_CUBLAS -DNOCHANGE -lstdc++ -ldl -L /usr/lib/lapack/liblapack.so -L /usr/lib/openblas-base/libopenblas.so
And have to following error:
Code: Select all
/tmp/tmpxft_00004e57_00000000-1_AA_TriEigenSolve.o: In function `main':
AA_TriEigenSolve.cpp:(.text+0x91): undefined reference to `dlamch'

Please help.

This works for all those interested

I'm glad that you figured out a link line that works.
The parse_opts function is used in the MAGMA testers and found in libtest.a library; you are of course welcome to use it, but it isn't required to use the MAGMA library. Likewise, the functions that the MAGMA testers use to verify the solution are in liblapacktets.a, which again you can use, but shouldn't be required to use the MAGMA library.
