PETSc 的通用生成文件

Generic Makefile for PETSc

本文关键字：文件 PETSc      更新时间：2023-10-16

我正在使用一个通用的makefile，如下所示：

# Determine the platform
UNAME_S := $(shell uname -s)
# CC
CC := g++
# Folders
SRCDIR := src
BUILDDIR := build
TARGETDIR := bin
# Targets
EXECUTABLE := NSDG
TARGET := $(TARGETDIR)/$(EXECUTABLE)
# Final Paths
INSTALLBINDIR := /usr/local/bin
# Code Lists
SRCEXT := cpp
SOURCES := $(shell find $(SRCDIR) -type f -name *.$(SRCEXT))
OBJECTS := $(patsubst $(SRCDIR)/%,$(BUILDDIR)/%,$(SOURCES:.$(SRCEXT)=.o))
# Folder Lists
# Note: Intentionally excludes the root of the include folder so the lists are clean
INCDIRS := $(shell find includes/**/* -name '*.h' -exec dirname {} ; | sort | uniq)
INCLIST := $(patsubst includes/%,-I include/%,$(INCDIRS))
BUILDLIST := $(patsubst includes/%,$(BUILDDIR)/%,$(INCDIRS))
# Shared Compiler Flags
CFLAGS := -c
INC := -I include $(INCLIST) -I /usr/local/include
LIB := -L /usr/local/lib -lblas -llapacke -lgsl -lgslcblas -lm
# Platform Specific Compiler Flags
CFLAGS += -std=c++11
$(TARGET): $(OBJECTS)
    @mkdir -p $(TARGETDIR)
    @echo "Linking..."
    @echo "  Linking $(TARGET)"; $(CC) $^ -o $(TARGET) $(LIB)
$(BUILDDIR)/%.o: $(SRCDIR)/%.$(SRCEXT)
    @mkdir -p $(BUILDLIST)
    @echo "Compiling $<..."; $(CC) $(CFLAGS) $(INC) -c -o $@ $<
clean:
    @echo "Cleaning $(TARGET)..."; $(RM) -r $(BUILDDIR) $(TARGET)
install:
    @echo "Installing $(EXECUTABLE)..."; cp $(TARGET) $(INSTALLBINDIR)
distclean:
    @echo "Removing $(EXECUTABLE)"; rm $(INSTALLBINDIR)/$(EXECUTABLE)
.PHONY: clean

目录结构如下，所有.cpp文件都包含在目录 src/中，相应的头文件(.h( 文件存在于目录 include/中。现在我想在其中添加 PETSc 库。我该怎么做？

我想通了。如果将来有人遇到困难，我将为涉及PETSc的项目发布通用的Makefile。

include ${PETSC_DIR}/lib/petsc/conf/variables
include ${PETSC_DIR}/lib/petsc/conf/rules
