Makefile

Dear all,

I have a quite simple question about how to manipulate "makefile.am". I intend to:

1. "CFLAGS" and "CXXFLAGS" have no value at all. I know that these values get "-g -O2" by default. On the other hand, when I try to set them as "CFLAGS = " in "makefile.am", I get warning messages that these values are user defined and should not be changes.

2. I want to add some libraries exactly at the end of the linker line. I am able to add my libraries to the beginning of linker line by adding:

Code:
AM_CXXFLAGS = $(INTEL_CXXFLAGS) $(MKL)

but in this case I get some undefined references. Is there any way to add link to some libraries afeter "-o xxx" when linker is called?

Thanks for your help,

Dan

iodbc-config(1) 					       iODBC Driver Manager						   iodbc-config(1)

NAME
iodbc-config - script to get information about the installed version of iODBC SYNOPSIS
iodbc-config [--prefix[=DIR]] [--exec-prefix[=DIR]] [--version] [--cflags] [--libs] [--static-libs] [--libtool-libs] [--odbcini] [--odbcin- stini] DESCRIPTION
iodbc-config is a tool that is used to configure to determine the compiler and linker flags that should be used to compile and link pro- grams that use iODBC. OPTIONS
iodbc-config accepts the following options: --version Print the currently installed version of iODBC on the standard output. --cflags Print the compiler flags that are necessary to compile an iODBC program. --libs Print the linker flags that are necessary to link an iODBC program using dynamic libraries (if supported). --static-libs Print the linker flags that are necessary to link an iODBC program using static libraries. --libtool-libs Print the linker flags that are necessary to link an iODBC program in a libtool environment. --odbcini Print the path of the system wide odbc.ini file. --odbcinstini Print the path of the system wide odbcinst.ini file. --prefix[=PREFIX] If specified, use PREFIX instead of the installation prefix that iODBC was built with when computing the output for the --cflags and --libs options. This option is also used for the exec prefix if --exec-prefix was not specified. This option must be specified before any --libs or --cflags options. If PREFIX is not specified, the --prefix flag shows where iODBC is currently installed. --exec-prefix=PREFIX If specified, use PREFIX instead of the installation exec prefix that iODBC was built with when computing the output for the --cflags and --libs options. This option must be specified before any --libs or --cflags options. EXAMPLES
To compile a program that calls the iODBC API, make sure the iodbc-config program can be found in the PATH environment variable, before using the following Makefile fragment: CFLAGS=`iodbc-config --cflags` LDLIBS=`iodbc-config --libs` iodbctest: iodbctest.c cc $(CFLAGS) -o iodbctest iodbctest.c $(LDLIBS) COPYRIGHT
