Tycho 安装 DYNAMITE

󰚰 3 min read

安装 gcc

下载源码并解压

wget https://ftp.gnu.org/gnu/gcc/gcc-13.2.0/gcc-13.2.0.tar.xz
tar -xf gcc-13.2.0.tar.xz
cd gcc-13.2.0

安装依赖库

./contrib/download_prerequisites

配置编译路径为 ~/app，并开启多线程编译

mkdir build && cd build
../configure --prefix=$HOME/app/gcc-13.2.0 --enable-languages=c,c++,fortran --disable-multilib
make -j$(nproc)
make install

用 gfortran --version 检查 gfortran 版本。之后

安装 galahad

首先 clone DYNAMITE 仓库到服务器：

git clone https://github.com/dynamics-of-stellar-systems/dynamite.git
cd dynamite

进入目录 legacy_fortran/galahad-2.3/

cd legacy_fortran/galahad-2.3/
./galahad-2.3

然后依据系统依次选择（我的系统 linux_x86_64，使用 gfortran 编译器）：

Select platform
- PC
Select operating system
- linux 
Select compiler
- GNU gfortran under linux (pc version)
Select subset of GALAHAD packages to be installed (the chosen subset will optionally be installed below)
- The QP packages and their interfaces to CUTEr
By default, the CUTEr you wish to use is installed in … Is this OK?
- n(o)
Enter alternative directory for CUTEr
- /home/.../dynamite/legacy_fortran/cuter
Do you now wish to compile the package subset you selected earlier?
- y(es)
The package subset may be installed in either single or double precision. Which precision do you require for the installed subset?
- D for double precision
Do you also wish to install the single precision version?**
- n(o)

更详细的操作说明以及其他操作系统安装方法参考 DYNAMITE 文档
最后添加路径和环境变量：

  • Bash
export GALAHAD="/home/.../legacy_fortran/galahad-2.3"
export MANPATH="$MANPATH:/home/.../legacy_fortran/galahad-2.3/man"
export PATH="$PATH:/home/.../legacy_fortran/galahad-2.3/bin"
  • fish
fish_add_path "/home/.../legacy_fortran/galahad-2.3/bin"
set -x GALAHAD "/home/.../legacy_fortran/galahad-2.3"
 
if not set -q MANPATH
	set -x MANPATH ""
end
set -x MANPATH $MANPATH "/home/.../legacy_fortran/galahad-2.3/man"

Compiling the Fortran programs

回到 legacy_fortran，简要修改 ./Makefile，确保：

  • 设置了正确的 GALAHADTYPE，分别对应于 gfortran in mac，ifrot for linux 和 gfortran in linux。
# MAC, gfortran
# GALAHADTYPE= mac.osx.gfo/double/
 
# linux, ifort
# GALAHADTYPE= pc.lnx.ifc/double
GALAHADTYPE= pc.lnx.gfo/double
  • 确保 all: 之后没有 triaxgasnnls
  • 使用 make all 开始编译

安装 DYNAMITE

我是用 uv 创建一个虚拟环境，然后在虚拟环境中安装 DYNAMITE。启用虚拟环境之后，进入 dynamite 目录，执行下方命令安装 DYNAMITE。

uv pip install .
uv pip install .[cvxopt]

测试

cd dev_tests/
uv run test_orbit_losvds.py
