clang-7: error: linker command failed with exit code 1 for macOS Big Sur

由 邮差的信 提交于 2020-12-22 19:13:17
问题 Installing R packages that need compiling in macOS is broken since Big Sur. Here is such an example. > install.packages('nlme') There is a binary version available but the source version is later: binary source needs_compilation nlme 3.1-150 3.1-151 TRUE Do you want to install from sources the package which needs compilation? (Yes/no/cancel) Yes installing the source package ‘nlme’ trying URL 'https://cran.rstudio.com/src/contrib/nlme_3.1-151.tar.gz' Content type 'application/x-gzip' length

Can C++17 be used together with CUDA using clang?

由 给你一囗甜甜゛ 提交于 2020-12-02 05:59:06
问题 As far as using nvcc , one needs to use the corresponding gcc (currently max. 5.4 I believe) in conjunction. This of course somewhat prevents one from using C++17 on the host side. Since C++17 can be compiled using clang 5 and upwards (see here), and one can compile cuda code as well (see here), is it possible to use both C++17 and CUDA at the same time (or can there be problems, e.g. with the CUDA runtime)? 回答1: Yes, as you already guessed the CUDA clang frontend is indeed ahead in C++

How do I compile C++ to JavaScript in a browser?

由 别来无恙 提交于 2020-12-01 07:15:10
问题 I'm aware of Emscripten and LLVM, but neither are written in JavaScript intended for a browser. As far as I can tell, the tools exist, but they haven't been put together, but I could very well be missing some key factor that makes it very difficult to compile C++ to JavaScript in a browser. So I'll mention my naive implementation: Compile Emscripten to C, then use Clang to compile it to LLVM, then use Emscripten to compile it to JavaScript. Compile Clang to LLVM, then compile that to

Syscall/sysenter on LLVM

由 我与影子孤独终老i 提交于 2020-11-30 08:23:12
问题 How do I write the LLVM bitcode required to emit an architecture-specific system call instruction? More specifically, clang supports inline assembly, and clearly supports emitting system calls (otherwise libc and vdso could not be compiled). How does the translation work for this, and how can I tickle it to reproduce this behavior? I understand LLVM itself may not understand the calling interface and register schedule used by various architectures in a sufficiently high-level manner to be

RNA velocity | RNA速率

由 天涯浪子 提交于 2020-11-27 02:27:08
单细胞转录组确实是利器，但我们大多只利用了表达的信息，而从reads到表达之间的信息完全被我们忽略了。 最近nature发了一篇单细胞方法类文章，讲得就是如何利用RNA velocity来做细胞发育路径的推断。 velocyto velocyto -notebooks RNA velocity of single cells 首先需要了解一些基本概念： RNA velocity：the time derivative of the gene expression state—can be directly estimated by distinguishing between unspliced and spliced mRNAs in common single-cell RNA sequencing protocols. a high-dimensional vector that predicts the future state of individual cells on a timescale of hours. 比较抽象，一开始很难理解。 half-life of mRNA：Translation in both prokaryotes and eukaryotes involves three phases: initiation, elongation, and
