hi guys I've one box where I just yesterday upgraded Centos. I wonder if that kernel upgrade process might somewhat troublesome. After that upgrade UEFI boot fails with: Failed to set MokListRT: Invalid Parameter Something has gone seriously wrong: import_mok_state() failed : Invalid Parameter Has anybody seen that? And maybe know to fix it? many thanks, L.

OK: despite Dirk's very kind help, I decided that trying to deal with R configuration and Debian configuration simultaneously was too difficult. I did manage to solve my problem by reconfiguring/making/ installing all of 2.3.1 from source: ./configure F77=/usr/bin/g77 make make install A few questions inspired by this experience: (1) it seems a bit odd that R sets F77=gfortran by

Does anybody know why two "-g" flags appear in the call to gcc in R CMD SHLIB Example: gcc -std=gnu99 -I/usr/share/R/include -DNDEBUG -fpic *-g* -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -D_FORTIFY_SOURCE=2 *-g* -c c_file1.c -o c_object1.o Surely it need only be listed once?

hi guys, I realize it's not necessarily Samba type of a question but since this community here is vast with lots of win experience I thought I'd poke - same one winstation(ver. 1903) and computer's domain users when logged in can connect WIFI no problems, only Samba domain users cannot (to the same WIFIs). Anybody? many thanks, L.

In trying to compile a package with c code using Rtools, -O3 is added by default. This comes from Makeconf? Compiler flags (CFLAGS="-O0 -g" ) set in src/Makevars.win or src/Makevars appear before this. nm pkg.dll reveals no symbols! How can I compile a Windows package with "-O2 -g"? Thanks, RT -- View this message in context:

I suggest reading the man page for 'hwclock'. Namely, the --utc option. If you don't tell your system that the BIOS is stored as UTC, then it will assume it's

When I install an R package with cpp codes such as rrcov via CRAN (under R 3.1.1, using no Makevars file and under Ubuntu 14.04 using GCC 4.8), the cpp code is compiled with the -o3 flag (in fact, looking at the Makeconf file this seem to again be the default since R 3.1.1) But when I install my own package via CRAN it is compiled with the -o2 flag. My questions are what is causing my

Hi All, I want to build a dedicated firewall/router as I am launching a NPO and I can host this in my garage. (Comcast offered me a 100 x 20 circuit for $99/mo with 5 statics) I used to run Untangle, but as of version 9, you are forced to use their build in protocol policies versus the firewalling I am used to (Deny All and then opening holes for specific IP's, etc). There are so many

PIC16 now has clang and llc based system to generate native assembly. We then use our native assembler (gpasm) and the native linker (mplink) to generate the final executable. How can I integrate these things with the driver llvmc to have gcc like user experience? Note that we also want to run llvm-ld in order to perform the LTOs in case of multiple files. - Sanjiv

Dear R development: I'm not sure if this is the appropriate list, but it's a start. I would like to put together a package which contains a CUDA program on Windows 7. I believe that it has to do with the Makeconf file in the etc directory. But when I just use the nvcc with the shared option, I can use the dyn.load command, but when I use the is.loaded function, it shows FALSE.
