building workspace has encountered a problem

【推荐阅读】微服务还能火多久？>>> 导入一个现有的项目后，eclipse要building workspace，而且发现在这个过程中一直在不间断地校验JavaScript，由于项目中有大量的JS代码，造成该过程很慢，这时再对eclipse进行其它操作，很容易导致eclipse卡死。有时候会出现 building workspace has encountered a problem 这样的错误。出现该错误之后，即使关闭eclipse再打开，之后还会报这样的错误：在网上查找以后，找到的解决方法：创建一个新的workspace，删除原来的workspace，并通过File-->Switch workspace选择使用新创建的workspace。设置buidling workspace时不校验JavaScript代码，右击项目-->properties-->Builders，在对应视图中取消JavaScript Validator选项。这样导入项目时就不会被building workspace占用大量的时间，也不会再出现上述错误。看到有说， (把project选项里的 building automatically前的勾去掉 ) 个人感觉应该没什么用，building workspacea这个任务始终都是要进行的。来源： oschina 链接： https://my

MinGW32: Linking against ImageMagick with -static flag

阅读更多关于 MinGW32: Linking against ImageMagick with -static flag

问题 I am currently trying to build a Windows-version of emacs that supports ImageMagick. For that purpose I have already compiled ImageMagick with MinGW32/MSys in order to get compatible library files. Basically linking also works, though I have to add explicitly -llibMagickCore-6.Q16 and -llibMagickWand-6.Q16 to the linking command through configure.bat 's --lib option. However, the binary distribution of emacs for windows is supposed to load, even when the dependencies are absent. This

Solve ld linker issues for building R source

阅读更多关于 Solve ld linker issues for building R source

问题 While trying to install R from source, I ran into linker issues, in particular: undefined reference to 'u_getVersion_58 I found limited information on this error (eg, this post on the RStudio forum). Despite running apt-get build-dep , these issues persisted. It is apparent from these comments by Dirk Eddenbuettel that it relates to libicu versions. I have libicu version 60, while R 3.6.0 and similar recent versions seem to require version 58. 回答1: We can install a previous version of libicu

阅读更多关于 What is the best way to check if I have a 32-bit or a 64-bit Linux?

问题 I have to check in CMake script if I have a 32-bit or a 64-bit Linux in order to know how to build a C++ program. Which command is the best choice : getconf LONG_BIT arch uname -m 回答1: Using CMake one possible way is to check the CMAKE_SIZEOF_VOID_P variable: if (CMAKE_SIZEOF_VOID_P EQUAL 8) message (STATUS "Compiling for 64-bit") endif() 回答2: I'd propose to use any two of the methods together . (or all three) Just for the backup, and to be cross platform. Another Linux distribution can use
