8 years ago Looks like you are missing ACML as reference BLAS.
You can uncheck "BUILD_TEST" from cmake (this will disable test) or supply path to ACML from cmake

8 years ago Cmake reported about ACML:
CMake Warning at CMakeLists.txt:218 (message):
Cannot find acml.h
CMake Warning at CMakeLists.txt:250 (message):
Cannot find libacmlI believe cmake abilities is enough to uncheck BUILD_TEST in auto mode when libacml not found. Additionally it may even report it, like that:
CMake Warning at CMakeLists.txt:218 (message):
Cannot find acml.h
CMake Warning at CMakeLists.txt:250 (message):
Cannot find libacml - tests disabled.I don't know if it is the right approach that if acml is missing BUILD_TEST should be disabled. I believe some people might actually want to build the test suite and install acml after the seeing warning message.

commented
8 years ago I just mean that any build error must be prevented on cmake stage if it can. If test build is checked but it required missing acml, cmake must fail or disable test, let compilation fails is bad idea.

8 years ago Hi Inferrna, I am thinking of a situation where the user actually want to build the test suite. But for some reason did not set up the CPU BLAS library (ACML or other) correctly. Should we silently disable building the test suite or should we throw a error message at configure (cmake) and build time? Wouldn't it be a surprise to the user that the test is not built after all?

8 years ago Hi with PR #181 on my Ubuntu system I can find and build test with libblas.so fairly straightforward. Can you verify that it works for you?

8 years ago I tried to locate correct libblas.so path in /usr/lib/pkgconfig/blas-netlib.pc but it also points to /usr/lib/libblas.so. I also reported bug about it https://bugs.launchpad.net/ubuntu/+source/blas/+bug/1515081

8 years ago On my Ubuntu system it picked up libblas.so under /usr/lib/libblas/ and worked fine. Does it work for you if linking with /usr/lib/libblas/libblas.so?

8 years ago With /usr/lib/libblas/libblas.so provided directly in cmake it builds fine. The problem will appear when someone like me install openblas. It would be nice to add into cmake first search Netlib_BLAS_LIBRARY:FILEPATH in /usr/lib/libblas/libblas.so and only after use /usr/lib/libblas.so (I use openblas by 2 reasons: according some tests it faster and I can compile it with modern gcc with a lot optimisations)

8 years ago Thanks. That makes sense. I don't know if there is a way to differentiate openblas from netlib blas since they are both libblas.so. Or is it easier for our testing suite to support cblas interface.

How about using the standard FindBLAS and FindLAPACK and specify the vendor you like via BLA_VENDOR?

8 years ago Hi. I have the same issue. Can we make the title of this thread a bit more specific though please ;-) eg undefined reference to "cdotusub_". Then it will be easy to find :-)

8 years ago Here are the locations of these libraries in openblas by the way:
$ dpkg -L libopenblas-base | grep so
/usr/lib/libopenblas.so.0
/usr/lib/openblas-base/libblas.so.3
$ dpkg -L libopenblas-dev | grep so
/usr/lib/libopenblas.so
/usr/lib/openblas-base/libblas.soHmmm, why not simply link to /etc/alternatives/libblas.so? Seems like that should always point to what the user wants?
But... I kind of hate the global 'variables' like /etc/alternatives actually. I think what I'd like is:
BLAS_LIBRARY=NOT-FOUND(note: edited to retype clblas as blas throughout the entire post :-P)

It unacceptable because it also may point to openblas ( or any other BLAS, see https://wiki.debian.org/DebianScience/LinearAlgebraLibraries ). We need to add some logic into cmake files for searching really netlib-blas. I'd prefer this way:

8 years ago A simpler solution would be to just run update-alternatives to point to NetLib's BLAS / LAPACK prior to building the test suite and reverting back to OpenBLAS afterwards.

8 years ago I think I tracked down this issue, and why it is acting inconsistently across platforms. Here's an example of the build failure I keep getting: https://gist.github.com/anadon/055791063f8e89d439cf
And according to this (https://stackoverflow.com/questions/10112185/shared-library-in-fortran-minimal-example-does-not-work) the issue is related to slightly incorrect build arguments.
I'm looking into how this can be rectified, but someone with more cmake experience should be able to go into this and fix it in a few minutes rather than a few days.

commented
8 years ago I think that it's the missing '-l' argument to blas in place of the inclusion of the library via a file path inclusion.

8 years ago So for the "undefined reference to `cdotusub_' issue. Pay attention your netlib blas version.
in lapack-3.6: "cdotusub" is defined in " lapack-3.6.0/CBLAS/src/cdotusub.f" but in lapack-3.5 there is no such file and such definition.
anadon
commented
8 years ago I have 3.6.0 installed. That's not the issue.
anadon
commented
8 years ago I think "/usr/lib64/libblas.so" should be "-lblas" but can't safely change and test the CMakeFile.txt to test that.
tingxingdong
commented
8 years ago If none of them works. Just replace cdotusub with cdotu. One is exactly the other's wrapper. but cdotu should be the standard interface.
anadon
commented
8 years ago I commented out the offending lines and it seems to build fine now. Might the function signatures vary from what it's expecting?
