Description Matthew Woehlke 2018-12-25 19:31:11 UTC
While trying to compile some code¹ that uses Eigen, I am receiving the following build error(s): /usr/include/eigen3/Eigen/src/Core/products/GeneralBlockPanelKernel.h:1226:13: error: inconsistent operand constraints in an ‘asm’ EIGEN_GEBGP_ONESTEP(0); (...several more of the same macro with different argument on subsequent lines...) It seems I am not the only one: https://github.com/tensorflow/tensorflow/issues/24457 (¹ https://github.com/kitware/kwiver — in arrows/core/triangulate.cxx) This appears to have started happening "recently", though it's been a while since I did a clean build of my code, so it's hard to say exactly when it started. Given the CentOS report, it seems plausible this is a compiler problem rather than an issue in Eigen itself?
Comment 1 Matthew Woehlke 2018-12-25 19:34:25 UTC
Note: downgrading from eigen3-devel-3.3.6-1.fc29.noarch to eigen3-devel-3.3.5-2.fc29.noarch seems to have "fixed" the problem.
Comment 2 Christoph Hertzberg 2018-12-25 19:54:25 UTC
Should be fixed in 3.3.7 as well *** This bug has been marked as a duplicate of bug 1643 ***
