Top Forums Programming Linker errors linking to .a files on OS X Post 302928590 by Don Cragun on Saturday 13th of December 2014 03:23:07 AM
Did you follow the MacPorts directions for uninstalling MacPorts, or did you just "rm" it?

I don't have any experience with MacPorts, but glancing through the on-line documentation it seems that MacPorts may change the target architecture to the port you were working on. That would explain the ld diagnostic:
Code:
ld: warning: ignoring file func.a, file was built for archive which is not the architecture being linked (x86_64): func.a
Undefined symbols for architecture x86_64:
  "_func", referenced from:
      _main in main.o

but I'm afraid I don't know how to help you correct the problem.

One possibility is that MacPorts might have installed alternative versions of gcc or ar in a directory in your PATH before the standard locations for those utilities. Does type ar gcc ld indicate any directory other than /usr/bin for any of those utilities? If it is something else, try:
Code:
/usr/bin/gcc -c func.c main.c
/usr/bin/ar -src func.a func.o
/usr/bin/gcc -o test main.o func.a

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
