添加共享库时scons编译失败

Question

我参与了一个包含C++、Fortran和Python的项目，编译是用scons做的。我尝试修改构建脚本以生成共享库：

diff --git a/src/scons/scons_ext/utils.py b/src/scons/scons_ext/utils.py
index bddadd6..896b2aa 100644
--- a/src/scons/scons_ext/utils.py

             program_dependencies = [self.rebase_dir(build_dir, target)] \
                                     + src_dependencies + dir_dependencies
             program = env.Program(program_name, program_dependencies)
+            if 'ssh-aerosol.f90' in target:
+                mylib = env.SharedLibrary('ssh-aerosol.so', program_dependencies)
             if program_name in self.command_line_target:
                 BUILD_TARGETS.append(program_name + env["PROGSUFFIX"])

但是修改后，我不得不运行编译脚本~5次才能在src文件夹中生成.so文件。我怀疑 scons 脚本没有以正确的顺序编译文件/在我修改后不理解文件之间的依赖关系。

2019 年 9 月 30 日之前可在此处获得代码的开发版本（不久将通过开源许可发布）：https://cloud.enpc.fr/s/mKNc4KZF6KKoWiB

编辑：获得工作库所需的编译运行s 的数量是可变的。该项目是在主目录中使用 ./compile 命令编译的。在日志文件中重定向 stdout 和 stderr 的编译输出显示这种错误：

编译问题的解决方案好像是：

             program_dependencies = [self.rebase_dir(build_dir, target)] \
                                     + src_dependencies + dir_dependencies
             program = env.Program(program_name, program_dependencies)
             # Generate shared library for ssh-aerosol
             if 'ssh-aerosol.f90' in target:
-                mylib = env.SharedLibrary('ssh-aerosol.so', program_dependencies)
+                mylib = env.SharedLibrary('ssh-aerosol.so', 'ssh-aerosol.f90')
             if program_name in self.command_line_target:
                 BUILD_TARGETS.append(program_name + env["PROGSUFFIX"])

             # In case another SConstruct wants to depend on this source
             # directory:
