配置文件模板以生成makefile

Linux中的几乎所有opensource c ++项目都有一个'configure'文件,用于在构建源代码之前生成Makefile。

我正在从头开始编写一个项目,这个'configure'文件有没有模板?

大多数情况下,配置文件不是手动创建的,而是由autoconf等工具生成的。然而,有更多的现代替代品,它们更容易使用。查看Qt的cmakeqmakescons

它由名为Autoconf的程序生成。

答案 2 :(得分:3)

configure文件是通过configure.ac文件中的autoconf生成的。这是我使用C ++ configure.ac的最小模板:

dnl Minimal autoconf version supported. 2.60 is quite a good bias.
AC_PREREQ([2.60])
dnl Set program name and version. It will be used in output,
dnl and then passed to program as #define PACKAGE_NAME and PACKAGE_VERSION.
AC_INIT([program-name], [program-version])
dnl Keep helpers in build-aux/ subdirectory to not leave too much junk.
AC_CONFIG_AUX_DIR([build-aux])
dnl Enable generation of Makefile.in by automake.
dnl Minimal automake version: 1.6 (another good bias IMO).
dnl foreign = disable GNU rules requiring files like NEWS, README etc.
dnl dist-bzip2 = generate .tar.bz2 archives by default (make dist).
dnl subdir-objects = keep .o files in subdirectories with source files.
AM_INIT_AUTOMAKE([1.6 foreign dist-bzip2 subdir-objects])

dnl Enable silent rules if supported (i.e. CC something.o instead of gcc call)
m4_ifdef([AM_SILENT_RULES], [AM_SILENT_RULES])

dnl Find a good C++ compiler.
AC_PROG_CXX

dnl Write #defines to config.h file.
dnl You need to generate config.h.in, for example using autoheader.
AC_CONFIG_HEADERS([config.h])
dnl Generate Makefile from Makefile.in.
AC_CONFIG_FILES([Makefile])
dnl This generates fore-mentioned files.
AC_OUTPUT

dnl行是您的评论(解释),您可以将其从文件中删除。

它假设您正在使用automake来生成Makefile。如果您不想这样,则需要手动准备Makefile.in(并删除AM_INIT_AUTOMAKE行)。

配置结果将写入config.h。你通常把它包括在内:

#ifdef HAVE_CONFIG_H
#    include "config.h"
#endif

我的Makefile.am模板(由automake使用):

# Programs which will be compiled and installed to /usr/bin (or similar).
bin_PROGRAMS = myprogram

# Source files for program 'myprogram'.
myprogram_SOURCES = src/f1.cxx src/f2.cxx
# Linked libraries for program 'myprogram'.
myprogram_LDADD = -llib1 -llib2

创建这两个模板后,您通常自己运行autoreconf -vi而不是随机工具。这将猜测你需要什么并运行它。

如果您需要更多信息,请随时告诉您,我很乐意解释。
