将源代码构建的库链接到由autotools管理的程序

Question

I have ac program which needs a library named libnuma to be installed. But I dont have root access in the parallel machine in which I need to run this program. So I downloaded the source code of libnuma and compiled it. I have a libnuma.a file which i assume is the library. I need to link this library with the c program that I have. This program uses autotools for generating the configuration files and the makefile. I am new to autotools. Please tell me what I have to do to link this library without being root.

It should be sufficient to set CPPFLAGS and LDFLAGS. First, try:

$ ./configure LDFLAGS=-L/path/to/lib CPPFLAGS=-I/path/to/include

(where libnuma.a is /path/to/lib/libnuma.a and numa.h is /path/to/include/numa.h. That is, specify the directories.) If that does not work, check config.log to see what went wrong. If the configure script for the program you are using was built with an old version of autoconf, you may need to do:

$ LDFLAGS=-L/path/to/lib CPPFLAGS=-I/path/to/include ./configure

instead. (The second invocation will only work in Bourne shells. With csh/tcsh, you will need to set the environment variables some other way, for example with env.) You also have the option of making those settings in the environment of your shell (eg, in a .bashrc) or in a config.site file.
