I installed following things:(as the listing order)
visual studio .net 2003 in E:
J2SE Runtime Enviroment 5.0 Update 5 in C:\Program Files\Java
ActivePerl 5.8.7 build 815 in C:\Perl
s60_2nd_fp2 in C:\Symbian
carbide_vs_20 and its help in C:\Symbian\Tools\NDS
Then I went to C:\Symbian\8.0a\S60_2nd_FP2\Series60Ex\helloworldbasic\group,and
used command line "makmake helloworldbasic.mmp vc7".
I could see the a "helloworldbasic.sln" and some other files were made.
I opened this file with Visual Studio .net, and then built the solution -- failed!
And the description is this :
