linux - OMP Cross compilation with x86_64-w64-mingw32-g++ -

-

I have a problem with the crosscompling C ++ program which takes advantage of the OpenMP library. I'm using Linux Ubuntu 12.04 LTS. I want to get a executable file running on Windows

I have no problem compiling the program with OMP with a regular G ++ command: < / P> 

  G ++ a.cpp b.cpp -o OMPres -pg -O3-I./ CBAS / Include -L-LCLAS

In addition to this When I try the cross-compilation without OMP, then everything is alright: 

  x86_64-w64-mingw32-g ++ A CPPP BCP-O3-i / CBLS / Evening ./CBLAS/cblas_WIN64.a./BLAS/blas_WIN64.a-o res.exe -l gfortran -static

But when I croscipil with it with the OMP Try:

Include x86_64-w64-mingw32-g ++ a.cpp b.cpp -O3-I./CBLAS/ ./CBLAS/cblas_WIN64 .a. / BLAS / Blas_Wine 64.AO Operates.XA-L Bluff -STeetic -Fopmomp

I get this error: a.cpp: 41: 17: Fatal error: Omp.h: No such file or directory compilation was exhausted.

I've found that where the omp.h file is located on my disk, and added the path to the command after executing it: 

  x86_64-w64 Include -mingw32-g ++ a.cpp b.cpp -O3-I./CBLAS/- include / usr / lib / gcc / x86_64-linux-gnu / 4.6/ ./CBLAS/cblas_WIN64.a./ I got another error:  x86_64 -w64-mingw32-g ++: error: libgomp .spec: No such file or directory   
 I have this file on disk so I want to copy it to different places. Shish and then it worked when I copied it directly in the directory where the compilation. Then another error occurred:  
  / usr / bin / x86_64-w64-mingw32-ld: can not be found - lgomp / usr / bin / x86_64-w64-mingw32-ld: no Can get -lrt collect 2: LD returns 1 exit status   
 I do not understand how compilers work at all I try to update all the amingwow-w64 compilers That, which I could get with APT-cache search but nothing helped. I do not know what I can do: (.   
 
 
 First of all, @ nmair Right from the Ubuntu x86_64-w64-mingw32 toolchane is crippled, and that you can make the toolchain yourself.  
 I suggest that you use that which will allow you to manually prepare a GCC Saves time and its every dependency should be sufficient for the purpose of the following steps:  
  # MXE GIT Clause Do not receive https://github.com/mxe/mxe.git and CD MX # settings cat  settings.mk MXE_TARGETS: = x86_64-w64-mingw32.static JOBS: = Create 4 EOF #GCC, libgomp, blas, and CLAS. It will take some time - add toolbar to j2 libgomp cblas # PATH #http: //htmlpreview.github.io/?https://github.com/mxe/mxe/ Blob / master / index.html # tutorial Step 4 Export View PATH = `pwd` / usr / bin: $ PATH # You do not need to see - I / CBLAS / include ./CBLAS/cblas_WIN64.a./BLAS/blas_WIN64 .a # Headers and libraries have been installed at standard location and # I already have `-lblblas -lblas` Used X86_64-w64-mingw32-g ++ a.cpp b.cpp -fopenmp -O3 -o res.exe -lcblas -lblas -lgfortran -lquadmath

I would like to create a fuel bar (empty with full tank). When the user touches the screen, the fuel once Dairejh these is my code: lifeBar = display.newImage ( "fuel_bar1.png") lifeBar.anchorX = 0 lifeboats. ======================== Lifetime Y = 37 screens Group: The Insert function (called Laifbar) However, I fuel Kansmoshn (equivalent to "pressed" variable to reduce the fuel tank "true") Have used. When pressed == is true, it means that the user is touching the screen: processed (fuel) processed () if life & gt; 0 and pressed == true remains = life - life 1 Life = life =. Wide-1 remains Value.text = string.format ("% d", life) End of this This function is active as the entrance event: runtime: addEventListener ( "Antrfrem" fuel Snsadna) it is very well, but my question is: pressed variable each time 5 seconds (once = = True) How is it possible to reduce the vitality width? I tried to add it to my touch even...
