rjulia on Windows/RStudio

[dgromer]

Building rjulia on Windows 7 64-bit with R 3.2.0 and Julia 0.3.9 (using devtools::install_github("armgong/RJulia", args = "--no-multiarch") fails with the following error:

However, after adding a Makevars.win with the contents of the Makevars plus PKG_CPPFLAGS+= -D_WIN32_WINNT=0x0600 (see JuliaLang/julia#9973) solved this problem.

Now when loading the package from within RStudio, the R session crashes. When loading rjulia in a R session in cmd.exe everything works fine. Any ideas?

[armgong]

could you enable RStudio log (https://support.rstudio.com/hc/en-us/articles/200554756-RStudio-Application-Logs ) and see what happend?
recently I am not test on windows , so didn't konw SRWLOCK problem, you can create pull request, I will merge it.

[dgromer]

RStudio writes neither to rdesktop.log nor rsession-USER.log upon crash. Maybe that's due to the fact that RStudio does currently not support crash reports on Windows (https://support.rstudio.com/hc/en-us/articles/200488518).

I guess I will write an issue to RStudio Support.

[armgong]

tested on my PC, found these
1 SRWLOCK issue is caused by Rtools have too old winnt.h (I use msys2+mingwbuild gcc 4.9.2 which have the define)

2 julia 0.39 and rjulia crash RStudio 0.99.442 (but run ok on RStudio-0.98.1103 ). this is RStudio 0.99.442 bug, to verify this just run following code ,it will crash rsession

  dyn.load('e:/julia/64/bin/libjulia.dll')

3 julia 0.4 and rjulia run on rstudio

[armgong]

to solve this problem,there two way
1 when use julia 0.39 and rjulia stay at RStudio-0.98.1103
2 when use RStudio 0.99.442 , need julia 0.4 and rjulia 0.4 branch

[dgromer]

RStudio 0.99.442 still crashes on my machine when using Julia 0.4 nightly build and rjulia 0.4 branch atdyn.load of libjulia.dll

[armgong]

Don't load rjulia just run dyn.load('e:/julia/64/bin/libjulia.dll') on rstudio see what happens ,or try rstudio nightly build 99.591

[dgromer]

dyn.load("C:/Julia-0.4.0-dev/bin/libjulia.dll") crashes on both RStudio 0.99.442 and 0.99.591.

[armgong]

on my PC both julia 0.3 and 0.4 run ok on RStudio-0.98.1103,so please stay on this version,don't use 0.99.
or somebody can summit a issue to rstudio,wait rstudio to solve it.

[armgong]

btw your julia 0.4 is own build or download from julialang.org? mine is own build and it can run on rstudio 0.99.591

[dgromer]

I use a 0.4 nightly build from julialang.org.

It works in RStudio 0.98.1103, so it seems to be a problem with either RStudio 0.99 or the nightly build from julialang.org. I will file an issue to RStudio.

[armgong]

thanks a lot

I tried to install rjulia on Windows 7 64-bit with R-3.2.0 and julia-0.3.9. The latest version fixed the SRWLOCK issue. However, I am still stuck at the final linking step.

I installed julia-0.3.9 with the (Windows Self-Extracting Archive (.exe)) binary package from http://julialang.org/downloads/. I wonder if it is necessary to build julia from scratch.

[armgong]

1 try add C:\Users\yanll\AppData\Local\Julia-0.3.9\bin to you system PATH
if 1 don't work
2 try modify Makevar.win latest line:
PKG_LIBS=-L$(libjuliapath) -ljulia

[yanlinlin82]

I had already added the directory to PATH, otherwise R won't be able to find the correct julia path. The second method does not help either.

I searched in my julia installation directory, and found that there is no any '.lib' or '.a' file. I tried also the Nightly build, but the same error exists.

Therefore, I guess it is necessary to build julia from scratch. I will try this way.

[armgong]

basically dynamic link on windows don't need .lib or .a file , just need libjulia.dll. build julia from scratch will not help.

according you compile output, it is R package compile problem,normally R try to compile both 32 and 64 bit package,but your julia in system path is only 32bit or 64 bit, so need use this like @dgromer to compile rjulia

devtools::install_github("armgong/RJulia", args = "--no-multiarch")

[yanlinlin82]

Thanks! It works now.
