Hi, I am trying to test the speed of my code on a Intel pc with Winxp and compare with gcc. But I must use fftw for my code to run. I currently use a precompiled version of fttw I pulled from the net which has been produced with the Intel icc-7.1/O3/G7. This works fine with the gcc-compiled (mingw) code. Would it be ok to try to do the same with the dmc? I am asking this because on trying compiling and linking with dmc I get the following - note that I have edited the sc.ini file and set the appropriate paths: C:\dm\bin>dmc main link main,,,user32+kernel32/noi; OPTLINK (R) for Win32 Release 7.50B1 Copyright (C) Digital Mars 1989 - 2001 All Rights Reserved main.obj(main) Error 42: Symbol Undefined _fftw_execute main.obj(main) Error 42: Symbol Undefined _fftw_execute_dft_r2c main.obj(main) Error 42: Symbol Undefined _fftw_execute_dft_c2r main.obj(main) Error 42: Symbol Undefined _fftw_plan_many_r2r main.obj(main) Error 42: Symbol Undefined _fftw_plan_dft_c2r_2d main.obj(main) Error 42: Symbol Undefined _fftw_plan_dft_r2c_2d main.obj(main) Error 42: Symbol Undefined _fftw_malloc --- errorlevel 7 What I am doing wrong? Thanks. --

Me Again <Me_member pathlink.com> In article <dtqpk5$2ljg$1 digitaldaemon.com>, Bertel Brander says... Many thanks for the prompt response. I actually were using a .lib library that I had downloaded together with the .dll. I was specifying in the sc.in LIB="% P%\..\lib";"% P%\..\mfc\lib";%LIB%;C:\FFTW;C:\dm\bin\fftw3.lib Anyway. I will try to recreate the .lib file. I will have to download implib from somewhere ... --Dont like.spam.thanks wrote:C:\dm\bin>dmc main What I am doing wrong?You can create a .lib file from the .dll and link to that.

Download MS Visual C++ installed but DUMPBIN nowhere to be seen (free version). Any ideas?In the version of ffw I downloaded there were no .lib's only .dll and the header. You have to use implib.exe to create the .lib It is a part of the standard package. In sc.ini you specify the path's to libraries, not the libraries themselves, as far as I know. So you must specify the .lib on the command line when compiling: dmc main ffw.lib -- Absolutely not the best homepage on the net: http://home20.inet.tele.dk/midgaard But it's mine - Bertel
