error: ‘FloatComplex {aka union <anonymous>}’ has no member named ‘x’

[vedranmiletic]

I'm building clBLAS on Fedora 25 with GCC 6.3.1, Mesa 17.1 git and ocl-icd 2.2.11. I have turned on every BUILD_* except BUILD_CLIENT, and I get:

I do not think you need ctrsm example. so remove everything related to ctrsm from the cmakefile: https://github.com/clMathLibraries/clBLAS/blob/master/src/samples/CMakeLists.txt#L64

[vedranmiletic]

Possibly, but it would be nice if it did not fail compilation.

[cirosantilli]

Reproduce on Ubuntu 16.10 with -DBUILD_SAMPLE.

FloatComplex is typedefed to cl_float2.

Recommend adding that build config to your test server.

[tingxingdong]

Can you make a pull request to fix it? Thank you.

[vedranmiletic]

Eventually yes, but not right now. There is more things I like to clean up in clBLAS and I will send those patches as well, but first I would like to get clBLAS working with Clover (tracking meta-bug) since it is a prerequisite for (at least) Octopus and Theano.

[TimmyLiu]

I wonder if the error error: ‘FloatComplex {aka union <anonymous>}’ has no member named ‘x’ is related to this ? I wonder if you can compile the example if you change result[i * ldb + j].x to result[i * ldb + j].s[0] and so forth.

[cirosantilli]

@TimmyLiu I think you are spot on... fix proposed at: https://github.com/clMathLibraries/clBLAS/pull/309
