thanks for the tip Brian. i thought that i had tried to -mno-cygwin option before but maybe i did not. i have a script file set up now with that command option:
$g++ -mno-cygwin -D__int64="long long" -shared -I "C:\Apps\Java\jdk1.6.0_05\include" -I "C:\Apps\Java\jdk1.6.0_05\include\win32" -I "C:\Users\usmsci\My Documents\shapefiles\shapelib-1.2.10\shapelib-1.2.10" -I "C:\Users\usmsci\My Documents\shapefiles\shapelib128_bin_win" -L "C:\Users\usmsci\My Documents\shapefiles\shapelib128_bin_win" com_radiancetech_dss_DataGathererShapeFileReader_DataGathererShapeFileReader.cpp -o libShapeData.dll "C:\Users\usmsci\My Documents\shapefiles\shapelib128_bin_win\shpopen.obj" "C:\Users\usmsci\My Documents\shapefiles\shapelib128_bin_win\dbfopen.obj" errors i get now are: Warning: .drectve '-defaultlib:LIBC' - unrecognized Warning: .drectve '-defaultlib:OLDNAMES' - unrecognized Warning: .drectve '-defaultlib:LIBC' - unrecognized Warning: .drectve '-defaultlib:OLDNAMES' - unrecognized fu000001.o:(.idata$2+0xc): undefined reference to '_libmsvcrt_a_iname' fu000004.o:(.idata$2+0xc): undefined reference to '_libmsvcrt_a_iname' undefined reference to '__nm___itob' Info: resolving __itob by linking to __imp___itob(auto_import) is there possibly another option that i need to add to the command line? thanks again for the help...!! chad On Sat, May 31, 2008 at 6:26 AM, Brian Dessent <[EMAIL PROTECTED]> wrote: > C S wrote: > >> gcc -D__int64="long long" -shared -I\C:\Apps\Java\jdk1.6.0_05\include >> -I\C:\Apps\Java\jdk1.6.0_05\include\win32 -I\c:\Users\usmsci\My >> Documents\shapefiles\shapelib128_bin_win -L\c:\Users\usmsci\My >> Documents\shapefiles\shapelib128_bin_win myFile.cpp -o >> libShapeData.dll c:\Users\usmsci\My >> Documents\shapefiles\shapelib128_bin_win\shpopen.obj >> c:\Users\usmsci\My >> Documents\shapefiles\shapelib128_bin_win\dbfopen.obj >> >> the errors i get are: >> >> Warning: .drectve '-defaultlib:LIBC' - unrecognized >> Warning: .drectve '-defaultlib:OLDNAMES' - unrecognized >> Warning: .drectve '-defaultlib:LIBC' - unrecognized >> Warning: .drectve '-defaultlib:OLDNAMES' - unrecognized >> >> c:\Users\usmsci\My >> Documents\shapefiles\shapelib128_bin_win\shpopen.o:shpopen.c >> (.text+0x1485):undefined reference to __assert > > You can't mix and match objects like that.
