I've tried recently to build a Debian package that uses eigen3 (the
latest beta) and it builds OK for x86, amd64 and ppc, but not for the
rest of Debian architectures...
My first question is: Is Eigen supposed to build on other archs.? If
yes, is there any -DXXX I should use in those cases?
These are the errors I found for each architecture:
alpha, ia64, sparc, s390:
========================
eigen3/Eigen/src/Core/util/Memory.h: In function 'void
Eigen::internal::queryCacheSizes_intel(int&, int&, int&, int)':
eigen3/Eigen/src/Core/util/Memory.h:631: error: impossible constraint in 'asm'
eigen3/Eigen/src/Core/util/Memory.h:660: error: impossible constraint in 'asm'
mips, mipsel:
=====================
/tmp/ccqL5d7b.s: Assembler messages:
/tmp/ccqL5d7b.s:78: Error: unrecognized opcode `cpuid'
/tmp/ccqL5d7b.s:124: Error: unrecognized opcode `cpuid'
......
In these last MIPS cases, I tried reducing the optimization level from
"-O3" to "-O2" and there are fewer "cpuid" errors, but there're still
many of them. I don't use any "-mtune", by the way.
Any advice?
Best,
JL
