Hi, I'm new to gnu autoconfig.
I have problems to use the AC_CHECK_HEADERS macro.
I want to check for headerfiles such as arpa/inet.h sys/socket.h, netinet/in.h and thread.h
Now the checking for arpa/inet.h went well, but sys/socket.h, netinet/in.h and thread.h failed,
but this headers are installed (sys/socket.h netinet/in.h in /usr/include and thread.h in /usr/local/include)
Also another problem is that the config.h is empty, after calling ./configure script.
configure.ac:
AC_INIT([mesydaq], [0.0.1], [steve.kreyer@xxxxxxxxxxx])
AC_CONFIG_SRCDIR([src/mesydaq.cpp])
AM_INIT_AUTOMAKE([1.7 gnu dist-bzip2])
AM_CONFIG_HEADER(config.h)
AC_ARG_ENABLE(debug,[ --enable-debug Turn on debugging],debug=true)
AC_ARG_WITH(threadpath,
AC_HELP_STRING([--with-threadpath], [specify the directory of the thread header files (default is /usr/local/include)]),
threadtop=$withval, threadtop=/usr/local/include)
AC_PROG_CC
AC_PROG_CXX
AC_HEADER_STDC([])
AC_CHECK_HEADERS([$(threadpath)/thread.h, sys/socket.h, netinet/in.h, arpa/inet.h])
AC_FUNC_ALLOCA
AC_CONFIG_FILES([Makefile src/Makefile])
AC_OUTPUT
./configure output:
...
checking /thread.h, usability... no
checking /thread.h, presence... no
checking for /thread.h,... no

Thanx for reply...
Steve
