Re: [Harbour] Re: HB_LONG_LONG_OFF in OS/2
Hi, With this code : #!/usr/local/bin/hbrun proc main() ? 1234567890123456789 ? 12345678901234567890 return i get these results (linux debian): 1234567890123456789 1234567890123457 strange no ?

I got inverse I get: With HB_LONG_LONG_OFF: ( set C_USR=-DHB_LONG_LONG_OFF ) [E:\harbour801\bin]hbrun.exe test.prg 1234567890123457000 Without HB_LONG_LONG_OFF: ( Rem set C_USR=-DHB_LONG_LONG_OFF ) [E:\harbour801\bin]hbrun.exe test.prg 1234567890123456789 David Macias ___ Harbour mailing list Harbour@harbour-project.org http://lists.harbour-project.org/mailman/listinfo/harbour

No, expected. 12345678901234567890 is too big to store in 64bit signed integer and double value has to be used with smaller (53bits only) precission. best regards, Przemek ___ Harbour mailing list Harbour@harbour-project.org http://lists.harbour-project.org/mailman/listinfo/harbour

Hi Chen, I tried compiling the myzip.prg from contrib\hbzlib and I got the following Unresolved external: '_get_crc_table' '_crc32' What am I missing? Thanks, Mario ___ Harbour mailing list Harbour@harbour-project.org http://lists.harbour-project.org/mailman/listinfo/harbour
RE: [Harbour] *CRC32() Function
Mario, Perhaps you are linking hrb.lib, the same happened to me, until I saw the readme.txt: "zlib library (http://www.zlib.net/) wrapper functions" I downloaded zlib1.dll Made an: implib zlib1.lib zlib1.dll This solved the problem.
