Valgrind Mojave

本文是给想在Mojave上编译安装valgrind的人一个参考。

Feb 27, 2013 Yes, Valgrind can be run on the OS X 10.8 and 10.9. Not perfect but downloads and runs on Mavericks.I suspect Macports does not do it well but Homebrew is tolerant and able to install Valgrind provided there are no other instances of valgrind and other Installers e.g Macports & Fink. Hello Valgrind Community, I'm a student working in IT at The University of Chicago, and our team has been tasked with updating our Mac lab machines to Mac OS Mojave. Some of our professors teach Valgrind in various courses as a useful debugging tool to help students catch memory bugs in their programs - I myself have benefited greatly from its use.

个人因为《Hands on concurrency with Rust》这本书的原因，需要安装valgrind。但是现在（2019/2/9）稳定版本的valgrind尚未支持Mojave，即不能通过Homebrew安装。valgrind的bug tracker里有这个问题的追踪，但是看状态估计离正式发布还需要时间（开源项目常有的事情，缺少资源，哎）。对话中给了一个github上的commit，看起来可以使用。

下载对应的repository，checkout到修改版的branch上

<p>按照valgrind自身网站上的说明，接下来是常规的compile install。</p><div><textarea wrap='soft' readonly='>./autogen.sh ./configure --prefix=foo make make install

如果你按照顺序执行的话，在make可能会碰到如下两个问题，所以在执行之前，建议先看一下可能碰到的问题

1. No rule to make target `/usr/include/mach/mach_vm.defs’

简单来说，就是没有找到定义文件。按照stackoverflow上一个问题的说法，你可以通过

解决，但是答案针对的不是Mojave，所以Mojave除了通过上述命令安装XCode之外，还需要解答中另外一个解决方案，即修改coregrind/Makefile（此文件在./configure之后生成)中mach_vm.defs的路径，具体如下

<table><tbody><tr><td><div><div>2</div><div>4</div></div></td><td><div><div> /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/include/mach/mach_vm.defs </div><div> /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/include/mach/task.defs </div><div> /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/include/mach/thread_act.defs </div><div> /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/include/mach/vm_map.defs</div></div></td></tr></tbody></table><p>也就是在原本 /usr/include/mach/mach_vm.defs 等文件前加上 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk 前缀，你可以 ls 一下看一下文件是否存在。</p><img src='https://opengraph.githubassets.com/9896c8283e8948a3ec55e8959af8f760738c88396b4ce7946f5461a70b3ab4c8/o4dev/homebrew-valgrind-mojave' alt='Mac' title='Mac' /><h3>2. vgpreload_core_x86_darwin_so-vg_preloaded.o ld: symbol(s) not found for architecture i386</h3><p>这个问题比较隐蔽，google搜不出来什么东西。直接看错误信息的话，大概知道MacOS下无法链接i386的程序，因为比较新的MacOS基本上只有x86_64。直接的解决方法是不让valgrind去编译i386架构的程序。</p><p>如果你留意了 ./configure 最后的输出的话，可以看到Secondary build arch</p><h2 id='valgrind-mac-os-mojave'>Valgrind Mac Os Mojave</h2><div><textarea wrap='soft' readonly='> Maximum build arch: amd64 Primary build arch: amd64 Secondary build arch: Build OS: darwin Link Time Optimisation: no Primary build target: AMD64_DARWIN Secondary build target: Platform variant: vanilla Primary -DVGPV string: -DVGPV_amd64_darwin_vanilla=1 Default supp files: exp-sgcheck.supp xfree-3.supp xfree-4.supp darwin10-drd.supp darwin18.supp

Primary build arch: amd64

Build OS: darwin

Primary build target: AMD64_DARWIN

Platform variant: vanilla

Primary -DVGPV string: -DVGPV_amd64_darwin_vanilla=1

Default supp files: exp-sgcheck.supp xfree-3.supp xfree-4.supp darwin10-drd.supp darwin18.supp

假如Secondary build arch不像上面那样为空的话，比如是i386，那么make时会出现以上问题。

在 configure 文件中，valgrind的注释提到在MacOS下会同时编译i386和x86_64，这是问题的根本原因，或者说valgrind在Mojave下编译的坑。幸好 configure 提供了只编译64位的选项，不需要修改 configure 文件。

总结一下，你要做的是
