R v3.4.0-2 无法在 Arch 上找到 libgfortran.so.3 [英] R v3.4.0-2 unable to find libgfortran.so.3 on Arch

问题描述

我刚刚休假一个月，所以我无法说出发生这种情况的确切时间，但是来自官方 Arch 存储库的 R 现在无法启动，引用

I was just on vacation for a month so am unable to say the exact point at which this happened, but R from the official Arch repos is now unable to start, citing

/usr/lib64/R/bin/exec/R: error while loading shared libraries: 
libgfortran.so.3: cannot open shared object file: No such file or directory

我认为可能是符号链接放置不当或损坏了，所以我查看/usr/lib 试图找到它:

I thought that perhaps a symlink was improperly placed or destroyed, so I looked in /usr/lib to try to find it:

ls -halt/usr/lib/libgfortran.so.*

lrwxrwxrwx 1 root root   20 May 16 03:01 /usr/lib/libgfortran.so.4 -> libgfortran.so.4.0.0
-rwxr-xr-x 1 root root 7.1M May 16 03:01 /usr/lib/libgfortran.so.4.0.0

libfortran.so.3 在 Arch 中被 libgfortran.so.4 取代了吗?如果是这样，是否有任何可能的解决方法让 R 与旧版本一起运行?

Has libfortran.so.3 been superseded by libgfortran.so.4 in Arch? If so, are there any possible workarounds for getting R to run with an older version?

如果其他人遇到此问题，r-devel AUR 正确编译并运行，因此希望在下一个版本中该问题将得到解决.

If anyone else comes across this, the r-devel AUR correctly compiles and runs, so hopefully on the next version bump the issue will be resolved.

推荐答案

确实，gfortran 7 将 ligfortran 版本提升到版本 4.参见 http://gcc.1065356.n8.nabble.com/patch-fortran-PR77828-Linking-gfortran-7-compiled-program-with-libgfortran-of-5-x-allowed-but-crashes-td1311625.html 它不向后兼容并且一些 API 发生了变化.

Indeed, gfortran 7 bumps the ligfortran version to version 4. See http://gcc.1065356.n8.nabble.com/patch-fortran-PR77828-Linking-gfortran-7-compiled-program-with-libgfortran-of-5-x-allowed-but-crashes-td1311625.html It is not backwards compatible and some APIs have changed.

如果您安装旧版本的 gfortran，您将获得 libgfortran.so.3.在您的系统中有多个版本是完全没问题的.也许有一种方法可以为版本 4 重建 R，但它可能需要更多的工作.查看如何重建软件的其他答案 https://stackoverflow.com/a/50744705/721644

If you install an older version of gfortran you will get libgfortran.so.3. It is completely fine to have multiple versions in your system. Maybe there is a way how to rebuild R for version 4, but it will be possibly more work. See other answers how to rebuild the software https://stackoverflow.com/a/50744705/721644
