I want to compile my project with autoconf/automake. There are 2 conditions defined in my configure.ac AM_CONDITIONAL(HAVE_CLIENT, test $enable-client -eq 1) AM_CONDITIONAL(HAVE_SERVER, test $enable-server -eq 1) I want to separate _LIBS from these 2 conditions in Makefile.am if HAVE_CLIENT libtest_LIBS = \ $(top_builddir)/libclient.la else if HAVE_SERVER libtest_LIBS = \ $(top_builddir)/libserver.la else libtest_LIBS = endif but else if HAVE_SERVER does NOT work. How to write 'else if' in makefile.am? R.D. ptomato's code can also be written in a cleaner manner like: ifeq ($(TARGET_CPU),x86)

automake：autotools 工具集使用速成 一般而言，对于小项目或玩具程序，手动编写 Makefile 即可。但对于大型项目，手动编写维护 Makefile 成为一件费时费力的无聊工作。 本文介绍 autotools 工具集自动生成符合 Linux 规范的 Makefile 文件。 如果读者没有安装 autotools 工具集，ubuntu默认自带了，如果没有，安装命令如下， $ sudo apt-get install automake 安装完成之后，会有如下工具可用， 一般大型项目，代码组织结构分为两种，一种是所有文件都在同一个目录下的 flat 结构，另一种是按层次组织的多文件夹形式。 先来看第一种： flat 结构的项目使用 autotools 工具集 本篇测试代码如下， #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include "sum.h" #include "sub.h" #include "mul.h" #include "div.h" int main() { printf("======== < Integer Arithmethic > ========\n"); int x, y; printf("Enter two integer: "); scanf("%d%d",

I have a project that I want to build using automake. The project consists of different components or modules, and there are inter module dependencies which require the project to be built in a specific order. For example: project dir/ module1 (core C shared lib) module2 (C++ shared lib wrapper around module 1) module3 (C++ application with dependency on module2) module4 (C library with dependency on module1) module5 (C application with dependency on module4) I am relatively new to automake, but I (just about) know how to use it to successfully build a single project. I would like to have a

I'm working on a C++ project that uses autoconf & automake , and I'm struggling to correctly set up the include paths in *CPPFLAGS . I've read about 3 hours worth of documents, and I can't figure it out yet. I'm not looking for a hack, but for the correct way to do this. Here is my conundrum. As I see it, there are 3 completely different sources for include paths: External libraries that must be installed along with my package, which are configured by configure --with-XXX=<PATH> . Within my package, some source files use #include <file.h> even when file.h is part of the package, so to compile

I have seen both in different things I have configured. What I the difference? Is it notable to use only one? Or does it not matter which one to use? configure.ac and configure.in are two possible names for the master Autoconf source file, which is processed by autoconf to generate the configure shell script. configure.ac is preferred for new packages, configure.in is an older name which still works. (The .in suffix is now recommended to be used only for files which will be processed by config.status , which is the result of running configure .) Makefile.am is an Automake source file. Automake

I've installed mingw and msys by using mingw-get-setup.exe . I've also installed Autotools(autoconf, automake,m4,libtool) into C:\/opt/autotools . When I run automake, the following error always occurs: configure.ac:11: error: required file './ltmain.sh' not found If I copy ltmain.sh from libtool’s installed tree, execution will finish normally. How can I configuure automake to find ltmain.sh without copying? In an autoconf / automake / libtool project you have to invoke: libtoolize : this copies/links a few support scripts, including ltmain.sh (which is the main component of libtool). aclocal

I'm trying to setup an automake project that uses a mix of libtool libraries and exectuables, and I'm having a hard time grokking the automake documentation, esp. as relates to telling the compiler to link against. So can someone explain the differences between LDADD and LIBADD ? Things like: when is one used over the other, which one takes -lname_of_library style values vs. direct filenames, etc. Whenever I try to read the relevant documentation, it seems like it assumes that I know things that I don't. Use the LIBADD primary for libraries, and LDADD for executables. If you were building a
