brew install clang-omp not working

由 爱⌒轻易说出口 提交于 2020-01-09 06:29:07
问题 I need to compile a C++ code with OpenMP on my Mac. Unfortunately the default version of clang installed on the Mac (703.0.31) does not support OpenMP. Therefore, I am trying to install the clang-omp package with brew (e.g., following this guide). The issue is that brew cannot find neither the libiomp, nor the clang-omp package: $ brew install clang-omp Error: No available formula with the name "clang-omp" ==> Searching for similarly named formulae... Error: No similarly named formulae found.

On mac, g++ (clang) fails to search /usr/local/include and /usr/local/lib by default

问题 I'm on a mac and I used homebrew to install gmp . Kyumins-iMac:gcjlib math4tots$ g++ main.cpp -lgmp -lgmpxx In file included from main.cpp:2: ./gcjlib.hpp:4:10: fatal error: 'gmpxx.h' file not found #include <gmpxx.h> ^ 1 error generated. So then I explicitly told g++ to use /usr/local/include Kyumins-iMac:gcjlib math4tots$ g++ main.cpp -lgmp -lgmpxx -I/usr/local/include ld: library not found for -lgmp clang: error: linker command failed with exit code 1 (use -v to see invocation) So then I

用Android平板来写代码

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 之前入了一个洋垃圾 华硕P00I，我对这款平板的第一印象是：屏幕好，电池耐用。如果忽略后压屏的缺点，还是很有性价比的。 除了平时看小说、PDF、PPT、视频，作为一个程序员(还没毕业)，想着是否可以更好的挖掘平板的利用价值，比如写代码，刷LeetCode。于是就有了这个踩坑教程，给其他有共同想法的人提供一个参考，少走弯路。 想要愉快地写代码当然需要一个外接键盘，我选择的键盘是 罗技K380。好像现在市面上可供选择的蓝牙键盘也不多，于是就挑了一款对自己口味的蓝牙键盘。 设备部分 华硕P00I 罗技K380 软件部分 Termux 终端模拟器（不需要ROOT也能使用） QQ输入法（其他输入法也可以，后面将说明我为什么选QQ输入法） 文本编辑器 既然是在命令行界面，那么vim自然是我们的首选 其他可用的编辑器请参考： https://wiki.termux.com/wiki/Text_Editors 安装软件 首先需要在平板上安装 Termux （在各个Android市场上应该都可以找到） 安装完成在 Termux 执行下面的命令安装vim命令行编辑器 pkg install vim 需要运行c/c++代码的话，那么需要还安装clang来编译和运行代码 pkg install clang 如果想编译Java代码的话

Finding all possible paths in a c/c++ program by LLVM

由 戏子无情 提交于 2020-01-07 02:03:29
问题 I am trying to find any possible path in my program by LLVM. Right now I can find paths from entry to exit BB of all functions in my code. However that's not what I need. What I need is extending CFG (maybe by inlining function calls?!) to have a CFG for entire source code and find paths in this extended CFG. I was thinking of using -inline pass first to inline all functions first and then run my pathfinder pass but as I observed -inline works only for functions which are explicitly mentioned

Building Gold linker in FreeBSD

问题 I followed the steps on http://llvm.org/docs/GoldPlugin.html#lto-how-to-build to build the gold plugin on FreeBSD but ! Heres a link to the screenshot of the error:http://postimg.org/image/anlpuufbl/ This is the error message that it shows and so I am also unable to get ld-new. I checked and no CFLAGS were set in etc/make.conf. How to proceed with the installation? I am using the deault clang version supplied with FreeBSD 10.1. 回答1: I think you just need to install devel/binutils port or its
