Managing conflicting versions of ruby gems

由 会有一股神秘感。 提交于 2019-12-02 04:15:52
问题 I am building a framework that loads user provided ruby code. It is basically a plugin mechanism. I want the user provide ruby code to be able to require gems of its own. I intend to have the "plugin" package include a vendor directory with the gems. How can I load gems that are required by the plugin without having them conflict with my framework's gems? For example, if my framework uses treetop version 1.3.0, and a plugin uses treetop 1.4.2 I want each to work with their specified version.

Finding the version of OSX inside java

I need to test if the version of osx is < 10.5 inside java is this possible? Try System.getProperty("os.name") and/or System.getProperty("os.version") It returns String HERE you can find more info about System.getProperties Use System.getProperty . System.getProperty("os.version"); The list of valid arguments for the function can be found here I think the System getProperties method can get that information for you. See "os.version" System.getProperty("os.version") Should return a string with three values for OS X, like: 10.5.1 You can also do System.getProperty("os.name") to make sure it's OS

This question already has an answer here: How To Run PHP From Windows Command Line in WAMPServer 11 answers When I start wamp it shows me this error about the PHP path but I don't even have this PHP version on my computer.

问题 So, here's the thing. To develop plugins for Maya on Linux, we have to compile with GCC 4.1.2. But this compiler doesn't support any of the new C++0x features. would it be possible to do something like this: gcc-4.6 -o test.cpp.o -c test.cpp gcc-4.1.2 -o exec_test test.cpp.o I have serious doubt it would be possible, but worth asking. If this is not possible, is there a way to achieve something similar ? 回答1: The ABI for those two GCC versions is compatible, the problem is that the object
