[英]How do I get rbenv to keep debugging symbols?
I installed the development version of Ruby 2 via rbenv
on Mac OS X v10.8.3, and am using it to compile a gem I'm working on. 我在Mac OS X rbenv
上通过rbenv
安装了Ruby 2的开发版本,并使用它来编译我正在处理的gem。 I have a memory problem I want to debug. 我有一个内存问题我想调试。 Unfortunately, whenever I run valgrind
, gdb
, or cgdb
in the context of a rake spec
, I get a whole bunch of errors like this one: 不幸的是,每当我在rake spec
的上下文中运行valgrind
, gdb
或cgdb
时,我都会遇到一堆像这样的错误 :
warning: Could not find object file "/private/var/folders/5f/h1s00nhn0rv4ckkpg4k_bwhr0000gn/T/ruby-build.20130331232604.54521/ruby-2.0.0-dev/main.o" - no debug information available for "main.c".
Obviously, that ruby-build
directory no longer exists. 显然, ruby-build
目录不再存在。
I get a series of likely-related errors from valgrind
. 我从valgrind
那里得到了一系列可能相关的错误 。 Here are examples: 以下是示例:
--2564-- /Users/jwoods/.rbenv/versions/2.0.0-dev/lib/libyaml-0.2.dylib:
--2564-- dSYM directory is missing; consider using --dsymutil=yes
If I try to use that --dsymutil=yes
option, I get errors which are basically the same as those from gdb
: 如果我尝试使用--dsymutil=yes
选项,我会得到与gdb
基本相同的错误:
warning: (x86_64) /private/var/folders/5f/h1s00nhn0rv4ckkpg4k_bwhr0000gn/T/ruby-build.20130331232604.54521/ruby-2.0.0-dev/ext/openssl/ossl_bn.o unable to open object file
Per an answer to another question, I tried running info target
inside gdb
. 根据另一个问题的答案,我尝试在gdb
运行info target
。 Here is the output. 这是输出。
Is there some way I can instruct rbenv
to put the debugging symbols somewhere that they won't get cleaned up? 有没有什么方法可以指示rbenv
将调试符号放在他们不会被清理的地方?
I'm using GCC 4.7.1, which I installed via homebrew. 我正在使用GCC 4.7.1,我通过自制软件安装。 My exact Ruby version string is ruby 2.1.0dev (2013-04-01 trunk 40029) [x86_64-darwin12.3.0]
, and my rbenv
version is 0.4.0. 我确切的Ruby版本字符串是ruby 2.1.0dev (2013-04-01 trunk 40029) [x86_64-darwin12.3.0]
,我的rbenv
版本是0.4.0。
According to the documentation for ruby-build : 根据ruby-build的文档:
Both ruby-build and rbenv install accept the -k or --keep flag, which tells ruby-build to keep the downloaded source after installation. ruby-build和rbenv install都接受-k或-keep标志,它告诉ruby-build在安装后保留下载的源代码。 This can be useful if you need to use gdb and memprof with Ruby. 如果您需要在Ruby中使用gdb和memprof,这可能很有用。
So try ruby-build install X -k
, where X is the version number. 所以尝试ruby-build install X -k
,其中X是版本号。
