MGIS Cross-compiling Windows #8

Closed TeroFrondelius closed 5 years ago

TeroFrondelius commented 5 years ago

Hi, I'm trying to cross-compile Windows binaries and got this error message:

Hi Tero, It seems that this is a side effect of removing --march=native (-Denable-portable-build=ON). See this thread: https://stackoverflow.com/questions/35884832/compile-error-undefined-reference-to-atomic-fetch-add-4 Would you try to enable this option again to see if this solve the issue ?

TeroFrondelius commented 5 years ago

Yes, I will try. Thanks for your help.

TeroFrondelius commented 5 years ago

@thelfer sorry for the stupid question, but can I do it like this:

cmake -DCMAKE_CXX_FLAGS="-march=native"
thelfer commented 5 years ago

Unfortunately no. For (probably) bad reasons, CMAKE_CXX_FLAGS is overriden during the configuration steps.

TeroFrondelius commented 5 years ago

Alright, no problem. I will try again, now interactively. Now I'm more convinced that I will need a good linux laptop as a work computer.

TeroFrondelius commented 5 years ago

Unfortunately no. For (probably) bad reasons, CMAKE_CXX_FLAGS is overriden during the configuration steps.

It looks like the CXXFLAGS is overwritten. I tried adding set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -march=native") both at the beginning and at the end of the file CMakeLists.txt, but it didn't help. I will try to dig deeper and find where is it overwritten.

TeroFrondelius commented 5 years ago

I used ccmake to interactively study the environment and I got the -march=native and -latomic correctly. Maybe it is something else.

TeroFrondelius commented 5 years ago

I got it working. I needed these changes in the CMakeLists.txt:

link_libraries("-latomic")
include_directories($prefix/include/julia)

I think the latter is because of the "collapsed" folder structure. Anyway one step forward. Here is the link to the actual implementation: https://github.com/TeroFrondelius/mgisBuilder/blob/52c30b37acd43bb286ec269cd34241323d00fb28/build_tarballs.jl#L28-L30
