I wrote a simple testing program as below // test.cpp program #include <iostream.h> #include <windows.h> #include <sql.h> #include <sqlext.h> void main() { HENV env_handle; if (SQLAllocEnv(&env_handle) != SQL_SUCCESS) { cout << "SQLAllocEnv fail" << endl; exit(-1); } else { cout << "SQLAllocEnv success" << endl; } SQLFreeEnv(env_handle); } At first, I invoke the compiler using the following command bcc32 -P -Ic:bcc55include -Lc:bcc55lib -c test The compile went thru successfully but during the linking time, the linker gave me two error messages. Unresolved external 'SQLAllocEnv' referenced from test.obj Unresolved external 'SQLFreeEnv' referenced from test.obj So I separate the compile and link step as below bcc32 -P -Ic:bcc55include -c test Then I invoke the linker as below ilink32 -Lc:bcc55lib;c:bcc55libpsdk test,,,,, It completed successfully. But when I run the executable, it gives me a message window saying "test is not a valid windows NT application". I tried it on another machine running Win98 and get the same result. (the error message is difference but I don't remember what it is now) Anyone can help???

How can I know what functions are contained inside those lib files? Any documentation I can search? This time I use the ODBC32.lib by guessing since I know I was using the ODBC related function.

For the ilink32 line, change it to ilink32 /Tpe/ap c0x32 test,test,,odbc32 import32 cw32 If afterwards it does not work then fix the ilink32.cfg file so the linker is properly installed. The /Tpe and /ap options I added are the same options I said to add in my previous reply. Quote: BTW where can we find those info like we need to put c0x32, import32 and cw32 in order to make the linker works. Read the tools help file entry on ILINK32 as I described in my previous reply. For what the names of the startup code and library files, run bcb5rtl.hlp and search for the string static runtime libraries If you don't have that help file then you have not downloaded the help files for the compiler. Go here and get them: http://tinyurl.com/2zri or, in its long form http://info.borland.com/techpubs/bcppbuilder/v5/updates/pro.html Many of the files pertain to things only found in the commercial distribution of the compiler. I think the ones which most pertain to you are B5RTL, B5LANG, B5SCL and B5MS (each with an extension of .ZIP). ..
