在centOS上安装PETSc时检测到一些奇怪的错误

如何解决在centOS上安装PETSc时检测到一些奇怪的错误

按如下方式构建PETSc时遇到了2个问题：

1. ./ configure --prefix = / home / lengjun / softwares / petsc_install
2. 使PETSC_DIR = / home / lengjun / softwares / petsc-3.14.1 PETSC_ARCH = arch-linux2-c-debug all
3. 进行PETSC_DIR = / home / lengjun / softwares / petsc-3.14.1 PETSC_ARCH = arch-linux2-c-debug安装
4. 进行PETSC_DIR = / home / lengjun / softwares / petsc_install PETSC_ARCH =“”检查

在步骤4中，它表明
