如何在makefile中运行./configure脚本

Question

I have tried the following:

$(shell ./libpng/configure)
./libpng/configure

under this context

all : build_jpeg build_libpng

#JPEG BUILD RULES
build_jpeg :
        make -C ./jpeg  

#LIB PNG BUILD RULES
build_libpng :
        $(shell ./libpng/configure)
        make -C ./libpng

What can I do to make this work?

Answer 1

What happens when you just do ./libpng/configure ? Make sure the configure script is executable! ( chmod +x ./libpng/configure )

Answer 2

If you want configure to generate the files in the folder libpng you can:

(cd ./libpng && ./configure)

Code in parentheses is executed in a subshell.
