Hello, I gotta start out by saying I'm new to perl. Just started using it a few days ago. My problem has come about because I'd like to convert a csv.txt to an Excel spread sheet. I added the Spreadsheet:WriteExcel module, but found that it recommeneded the Text:CSV_XS module. So, I downloaded the tar file and expanded it into a temp dir. The perl Makefile.pl command works find. However, when I run the nmake command a bunch of stuff appears like "cl -c -nologo -01 -MD -Zi -DNDEBUG..." following this huge string of what appears to be parameters a message says "cl" is not recognized as internal or external command, operable program or batch file. NMAKE : fatal error U1077: 'C:\WINNT\system32.exe' : return code '0x1' Stop. From this I can only guess that something may be missing from my PATH, but that's only a guess. If you can help me figure out what's wrong I'd appreciate it.
