.....], install.wrapper=NULL) The argument value I would typically want to supply on my system (running in a KDE Session) would be: install.wrapper="kdesu --" . I.e. I would like to run the R CMD INSTALL command through kdesu. Technically it would basically function like this: Instead of cmd0 <- paste(file.path(R.home("bin"),"R"), "CMD INSTALL") in install.packages (), it would read cmd0 <- paste(install.wrapper, file.path(R.home("bin"),"R"), "CMD INSTALL") This feature would save me a lot of small hazzles.

Hi, LLVM community, I found an issue in my using scenario. We deliberately parse a bitcode file twice. It contains a named struct type. eg. %struct.cmd = type { float, float, float, float, float, i32 }. In the second module->dump, %struct.cmd becomes %struct.cmd0. my code is simplified like this. int main() { llvm::LLVMContext &llvmCtx = llvm::getGlobalContext(); string ErrMsg; string filename = "wrapper.bc"; llvm::OwningPtr<llvm::MemoryBuffer> File; if (llvm::MemoryBuffer::getFileOrSTDIN(filename, File)) {...

...rough without problem. I traced the problem to a call to utils::install.packages(), where the option quiet is passed on. In utils::install.packages(), the problem seems to lie in the following call of system2(): output <- if (quiet) FALSE else "" [...] status <- system2(cmd0, args, env = env, stdout = output, stderr = output) Manually changing stdout to "" makes the program run through without error (but then the output is there again, of course...). The function system2 seems to be a wrapper around .Internal(system(command, flags...
