libXft.so.2: cannot open shared object file
时间: 2024-05-22 16:09:01 浏览: 13
libXft.so.2是一个动态链接库,它提供了一些函数和变量,可以被其他程序调用。当你启动一个程序时,它会检查需要的动态链接库是否存在。如果该库不存在,则会出现"cannot open shared object file"的错误消息。
这通常是因为系统中缺少了该库或者路径不正确导致的。你可以使用以下命令来查看该库是否存在:
```
ls /usr/lib/x86_64-linux-gnu/libXft.so.2
```
如果该库存在,你可以通过以下命令将路径添加到LD_LIBRARY_PATH中,让系统能够找到该库:
```
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/x86_64-linux-gnu
```
如果该库不存在,你可以尝试通过以下命令安装该库:
```
sudo apt-get install libxft2
```

EGSnrc 安装tips for Ubuntu
Sure, here are some tips for installing EGSnrc on Ubuntu:
1. Update your system: Before starting the installation process, it's always a good idea to update your system. Open a terminal and run the following command:
```
sudo apt update && sudo apt upgrade -y
```
2. Install required dependencies: EGSnrc requires some libraries and packages to be installed. Run the following command to install them:
```
sudo apt install build-essential gfortran libx11-dev libxt-dev libxpm-dev libxft-dev libxmu-dev libglu1-mesa-dev
```
3. Download the EGSnrc distribution: Visit the EGSnrc website (https://nrc-cnrc.github.io/EGSnrc/) and download the latest distribution file (e.g., egsnrc_vn.mmm.tar.gz), where "vn" represents the version number and "mmm" represents the release number.
4. Extract the distribution: Open a terminal and navigate to the directory where you downloaded the distribution file. Use the following command to extract it:
```
tar -xvf egsnrc_vn.mmm.tar.gz
```
5. Set up environment variables: In order to use EGSnrc, you need to set up some environment variables. Open your shell configuration file (e.g., ~/.bashrc) in a text editor and add the following lines at the end:
```
export EGS_HOME=/path/to/egsnrc
export EGS_CONFIG=/path/to/egsnrc/HEN_HOUSE/specs/your_machine_name
export PATH=$PATH:$EGS_HOME/bin/$my_machine
```
Replace "/path/to/egsnrc" with the actual path where you extracted the EGSnrc distribution, and "your_machine_name" with the appropriate name for your machine (e.g., linux).
6. Compile EGSnrc: Open a terminal and navigate to the EGSnrc directory. Run the following command to compile EGSnrc:
```
make
```
7. Verify the installation: After the compilation process completes successfully, you can run some example simulations provided with EGSnrc to verify the installation. Refer to the EGSnrc documentation for instructions on running the examples.
That's it! You have now successfully installed EGSnrc on Ubuntu. Remember to consult the EGSnrc documentation for further usage instructions and details.
