[R-pkg-devel] [BULK] Re: [Rd] "not a valid win32 application" with rtools40-x86_65.exe on Windows 10

Hi, Simon et al.


[changing to "R-package-devel, because I've heard complaints that this 
may not be appropriate for R-devel.]


 ????? I'm still having problems.? I found that I had Java twice in the 
path and deleted both versions (~\AdoptOpenJDK\jdk-11.0.6.10-hotspot\bin 
and ~Java\jre1.8.0_241). That seemed not to change anything as far as I 
can tell.


 ????? I have both directories for both "~Rtools" and "~rtools40", and 
the path includes "~rtools40\bin".? When running R4.0.0 within RStudio, 
"install.package('rJava', type='source', INSTALL_opts = 
'--merge-multiarch') complained, "WARNING:? Rtools is required ... but 
no version compatible ... was found.? Note that the following 
incompatible versions(s) ... were found:? - Rtools 3.5".? When I run r 
in a CMD prompt, I don't get that warning.? However, both complain,


 ????? warning in system("sh ./configure.win") : 'sh' not found


 ????? When I tried "install.packages('rJava')", it seemed to work OK 
(though I still got the complaint from R within RStudio that it could 
not find rtools40).


 ????? And my primary problem is unchanged:? "R CMD check 
Ecfun_0.2-4.tar.gz" ends with the following:


Error:? package or namespace load failed for 'Ecfun':
 ? .onLoad failed in loadNamespace() for 'rJava', details
 ?? call: inDL(x, as.logical(local), as.logical(now), ...)
 ?? error:? unable to load shared object 'c:/Program
Files/R/R-4.0.0/library/rJava/libs/i386/rJava.dll':
 ?? LoadLibrary failure: ^1 is not a valid win32 application


 ????? The same package on my Mac quits with a LaTeX error I have yet to 
figure out how to fix.


 ????? Suggestions?
 ????? Thanks,
 ????? Spencer Graves

Spencer,

you shouldn't have anything on the PATH, the location of Java is taken 
from the registry so you only need t have a valid installation of 
Java. Better don't set PATH or JAVA_HOME as it will stop rJava from 
working if you get it wrong. The errors on Windows are confusing, the 
actual error is shown via GUI as pop-up, what they report in the 
console is not the real error.

Re installation from source - it sooks like you either don't have 
Rtools40 or you didn't set PATH properly. If I recall the new Rtools40 
no longer set the PATH (for whatever reason) so you have to do it by 
hand and the instructions it gives you are not working for the command 
shell.

Cheers,
Simon

Hello, All:


??????? "00install.out" from "R CMD check Ecfun_0.2-4.tar.gz" 
includes:

This is an error in loading the rJava package, so it is not related to
rtools40, and probably inappropriate for this mailing list.

As Simon suggested, you may have to install the 32-bit Java JDK. See
also this faq: 
https://github.com/r-windows/docs/blob/master/faq.md#how-to-install-rjava-on-windows 

?????? In fact I had both 32- and 64-bit Java installed but only the 
64-bit was in the path.? I added the 32-bit, but that did not fix the 
problem.? The last 2.5 lines in the section "How to install rJava on 
Windows?" to which you referred me reads:


to build rJava from source, you need the --merge-multiarch flag:

install.packages('rJava', type = 'source', 
INSTALL_opts='--merge-multiarch')


?????? When I tried that, I got:


Warning in system("sh ./configure.win") : 'sh' not found


*** ON THE OTHER HAND:? The error message above says 'c:/Program
Files/R/R-4.0.0/library/rJava/libs/i386/rJava.dll':
??? LoadLibrary failure: ^1 is not a valid win32 application

Is "rJava.dll" a valid win32 application?

?????? Suggestions?
?????? Thanks,
?????? Spencer Graves


p.s.? A similar problem with rJava a month ago was fixed by installed 
64-bit Java.? Now with the upgrade to R 4.0.0 and rtools40, this no 
longer works.
