Your package doesn't need to rename the shared library. > D:\rtools45\x86_64-w64-mingw32.static.posix\bin/ld.exe: cannot find > -lOpenCL: No such file or directory That could be due to the OpenCL SDK shipping the import library in lib/x86_64 instead of lib/x64 where your package's 'configure.win' expects it, or for some other reason. When you discussed the installation of OpenCL SDK on Win-Builder with Dr. Uwe Ligges, was a specific version of it mentioned? -- Best regards, Ivan [*] https://github.com/s-u/OpenCL/pull/20 ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
