在 Ubuntu 10.04 LTS 上从 Fortran 源创建 Python C 模块

发布于 2024-08-31 04:03:00 字数 8960 浏览 9 评论 0原文

在我从事的一个项目中，我们使用使用 f2py 从 Fortran 编译的 Python C 模块。我在 Windows 7 32 位（使用 mingw32）和在 32 位 Linux 上构建的服务器上构建它没有任何问题。 但我最近在我用于开发的笔记本电脑上安装了 Ubuntu 10.04 LTS 64 位，当我构建它时，我收到很多警告（即使我显然已经安装了所有 gcc/fortran 库/编译器），但它确实完成构建。然而，当我尝试在应用程序中使用内置模块时，大多数模块似乎运行良好，但随后崩溃并出现错误：

* glibc 检测到 * /home/botondus/Envs/gasit/bin/python: free(): 无效的下一个大小（快速）: 0x0000000006a44760 ***

运行时出现警告 f2py -c -m module_name ./fortran/source.f90

我尝试通过安装 gfortran multilib 软件包并使用 -m32 选项运行 f2py 来构建 32 位版本（但没有成功）：

f2py -c -m module_name ./fortran/source.f90 --f77flags="-m32" --f90flags="-m32"

关于我可以尝试构建 32 位版本或正确构建 64 位版本的任何建议？

编辑：看起来它在子例程结束时崩溃了。 “写入”执行得很好......这很奇怪。

     write(6,*)'Eh=',Eh

end subroutine calcolo_involucro

完整的回溯非常长，我不确定它是否有任何帮助，但这里是：

In a project I work on we use a Python C module compiled from Fortran with f2py. I've had no issues building it on Windows 7 32bit (using mingw32) and on the servers it's built on 32bit Linux.
But I've recently installed Ubuntu 10.04 LTS 64bit on my laptop that I use for development, and when I build it I get a lot of warnings (even though I've apparently installed all gcc/fortran libraries/compilers), but it does finish the build. However when I try to use the built module in the application, most of it seems to run well but then it crashes with an error:

* glibc detected * /home/botondus/Envs/gasit/bin/python: free(): invalid next size (fast): 0x0000000006a44760 ***

I have tried building a 32bit version by installing the gfortran multilib packages and running f2py with -m32 option (but with no success):

f2py -c -m module_name ./fortran/source.f90 --f77flags="-m32" --f90flags="-m32"

Any suggestions on what I could try to either build 32bit version or correctly build the 64bit version?

Edit: It looks like it crashes right at the end of a subroutine. The 'write' executes fine... which is strange.

     write(6,*)'Eh=',Eh

end subroutine calcolo_involucro

The full backtrace is very long and I'm not sure if it's any help, but here it is:

幸运的是，设法解决了这个问题。
我似乎没有注意到 Ubuntu 10.04 存储库中的 numpy 软件包版本只有 v1.3.0。我删除了 numpy，然后从源代码构建了 v1.4.1。
之后重新运行 f2py 确实给出了相同的警告，但是使用该模块不会再产生崩溃。

Fortunately managed to solve this.
It seems I didn't notice that the numpy package version in the repositories for Ubuntu 10.04 are only v1.3.0. I removed numpy, then built v1.4.1 from source.
After that re-running f2py did give the same warnings, however using the module does not produce the crash anymore.
