Hi R package developers,
I'm developing an R package that wraps NREL's SSC library (https://sam.nrel.gov/), which involves including one header file and linking to one dll. Thus far it is only tested in linux (works just fine there) but I am having trouble building/installing on Windows. The package name is "ssc", after it is all done compiling it says: > * DONE (ssc) > Error in inDL(x, as.logical(local), as.logical(now), ...) : > unable to load shared object 'C:/Users/EZRATU~1/AppData/Local/Temp/RtmpSaKZH0/pkgload13b41ff33604/ssc.dll': > LoadLibrary failure: The specified procedure could not be found. > Calls: suppressPackageStartupMessages ... <Anonymous> -> load_dll -> library.dynam2 -> dyn.load -> inDL > Execution halted > > Exited with status 1. My Makevars.win file, if useful, looks like: PKG_CPPFLAGS=-I. -I"$C:/SAM/2021.12.02/runtime" PKG_LIBS=-Wl,-rpath,$C:/SAM/2021.12.02/x64 -L"$C:/SAM/2021.12.02/x64" -lssc the second includes is to pick up sscapi.h which is a necessary header file for using this library, The package relies heavily on Rcpp; My full sessionInfo() is: R version 4.1.2 (2021-11-01) Platform: x86_64-w64-mingw32/x64 (64-bit) Running under: Windows 10 x64 (build 19044) Matrix products: default locale: [1] LC_COLLATE=English_United States.1252 LC_CTYPE=English_United States.1252 [3] LC_MONETARY=English_United States.1252 LC_NUMERIC=C [5] LC_TIME=English_United States.1252 attached base packages: [1] stats graphics grDevices utils datasets methods base loaded via a namespace (and not attached): [1] Rcpp_1.0.7 rstudioapi_0.13 magrittr_2.0.1 usethis_2.1.5 [5] devtools_2.4.3 pkgload_1.2.4 R6_2.5.1 rlang_0.4.12 [9] fastmap_1.1.0 fansi_0.5.0 tools_4.1.2 pkgbuild_1.3.0 [13] sessioninfo_1.2.2 utf8_1.2.2 cli_3.1.0 withr_2.4.3 [17] ellipsis_0.3.2 remotes_2.4.2 rprojroot_2.0.2 tibble_3.1.6 [21] lifecycle_1.0.1 crayon_1.4.2 processx_3.5.2 purrr_0.3.4 [25] callr_3.7.0 vctrs_0.3.8 fs_1.5.2 ps_1.6.0 [29] testthat_3.1.1 memoise_2.0.1 glue_1.6.0 cachem_1.0.6 [33] pillar_1.6.4 compiler_4.1.2 desc_1.4.0 prettyunits_1.1.1 [37] pkgconfig_2.0.3 and I have rtools40 installed in C:\rtools40. --no-multiarch is I read on the internet in various places that this could have something to do with 64 vs 32-bit architecture, but everything looks like it's targeting a 64-bit architecture and the DLL I'm linking to is 64-bit. Any ideas? Thanks so much! -Ezra ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
