具有多个目标的Makefile [英] Makefile with multiple targets

问题描述

希望这是一个非常简单的问题.我有一个makefile模式规则，如下所示:

Hopefully this is a very simple question. I have a makefile pattern rule that looks like this:

%.so : %.f %.pyf
    f2py -c -L${LAPACK_DIR} ${GRASPLIBS} -m $* $^ ${SOURCES} --opt='-02' --f77flags='-fcray-pointer' >> silent.txt

我希望makefile生成多个.so文件，因此我尝试通过执行以下操作来使其生成两个文件(radgrd_py.so和lodiso_py.so):

I want the makefile to build a number of .so files, so I tried to get it to build two files (radgrd_py.so and lodiso_py.so) by doing this:

radgrd_py.so lodiso_py.so:

%.so : %.f %.pyf
f2py -c -L${LAPACK_DIR} ${GRASPLIBS} -m $* $^ ${SOURCES} --opt='-02' --f77flags='-fcray-pointer' >> silent.txt

，然后尝试以下操作:

radgrd_py.so:

lodiso_py.so:

%.so : %.f %.pyf
f2py -c -L${LAPACK_DIR} ${GRASPLIBS} -m $* $^ ${SOURCES} --opt='-02' --f77flags='-fcray-pointer' >> silent.txt

但是在每种情况下，它只会构建我指定的第一个目标.如果我运行'make radgrd_py.so'可以正常工作，我只是不确定如何指定需要构建的文件列表，这样我就可以运行'make'.

But in each case, it only builds the first target that I specify. If I run 'make radgrd_py.so' it works fine, I'm just not sure how to specify a list of files that need to be built so I can just run 'make'.

推荐答案

通常的技巧是添加一个虚拟"目标作为第一个目标，该目标取决于运行普通make时要构建的所有目标:

The usual trick is to add a 'dummy' target as the first that depends on all targets you want to build when running a plain make:

all: radgrd_py.so lodiso_py.so

惯例是将此目标称为全部"或默认".为了更加正确，请在Makefile中添加以下行，以使make知道这不是真实文件:

It is a convention to call this target 'all' or 'default'. For extra correctness, let make know that this is not a real file by adding this line to your Makefile:

.PHONY: all
