Hi. I just installed MinGW-2.0.0-3. I entered, compiled and = sucessfully ran the simple "hello" examples shown on the "docs" page = http://www.mingw.org/docs.shtml. Then I tried to compile a MySQL sample program from the New Rider book, = client4.c. I modified the makefile for my environment and ran = mingw32-make. It generated a ton of errors, mostly about some sort of = "parse error before '*' token" in "c:/progra~1/mysql/include/mysql.h." I wanted to save and/or redirect the output to an error file but I = haven't had much sucess. The "tee" program shown below is an MS-DOS = equivalent to it's Unix counterpart ... and btw, this code, client4.c, = compiles and runs fine on my FreeBSD box. Neither D:\Prog\MySQL\Client4>mingw32-make | tee > error or D:\Prog\MySQL\Client4>mingw32-make > error produce an error file with any information in it. So how does one = redirect the screen output with MinGW? I'll follow up with the MySQL issue once I can create an error output = file. Don |

You can replace it with a more powerful shell like the bash provided by MSYS (links at www.mingw.org) and then just do what you'd normally do in *nix, like make 2>&1 |less Or you can get a program to handle redirection in a less powerful shell; I used to use DJ Delorie's 'redir' for that, something like redir -eo make |less (IIRC) to redirect stderr ('e') to stdout ('o'). Try finding this at www.delorie.com . Especially since you have experience with *nix, I'd recommend replacing the shell. BTW, with MSYS you can download *nix software and do './configure && make'. |

Thanks for your input, Greg. I loaded up MSYS and now have some output to paw through. The background: I'm trying to learn C and C++ by practicing with MySQL and it's C API. I'm familiar with MySQL from a PHP standpoint, so it really is just C and the Windows API that I'm trying to learn. I decided to start with the "Client4.c" example in the New Riders MySQL book by Paul DuBois. I'm going to start with my experience trying to compile this program with the Borland C++Builder in the hope that *more* information will be better than less. My first attempt at compiling client4.c was with Borland's C++Builder 6. It gave me grief with the following error message: Error E2139 c:\progra~1\mysql\include\mysql_com.h 119: Declaration missing ; I searched the internet and found only one instance of "mysql_com.h" and "Declaration missing;" That thread said to: #include <winsock.h> in my code, which I did. I mention all of this because the same "#include <winsock.h>" got me past the initial error I was having with MinGW. Borland's compiler liked the corrected programs (3 warnings) but now the linker wasn't happy and spit out the following errors: Borland C++ 5.6 for Win32 Copyright (c) 1993, 2002 Borland client4.c: Warning W8075 client4.c 46: Suspicious pointer conversion in function main Warning W8065 client4.c 49: Call to function 'getopt_long' with no prototype in function main Warning W8070 client4.c 101: Function should return a value in function main Turbo Incremental Link 5.60 Copyright (c) 1997-2002 Borland Error: Unresolved external '_optarg' referenced from D:\PROG\MYSQL\CLIENT4\CLIENT4.OBJ Error: Unresolved external '_my_init' referenced from D:\PROG\MYSQL\CLIENT4\CLIENT4.OBJ Error: Unresolved external '_load_defaults' referenced from D:\PROG\MYSQL\CLIENT4\CLIENT4.OBJ Error: Unresolved external '_getopt_long' referenced from D:\PROG\MYSQL\CLIENT4\CLIENT4.OBJ Error: Unresolved external '_optind' referenced from D:\PROG\MYSQL\CLIENT4\CLIENT4.OBJ Error: Unresolved external '_get_tty_password' referenced from D:\PROG\MYSQL\CLIENT4\CLIENT4.OBJ Error: Unresolved external '_do_connect' referenced from D:\PROG\MYSQL\CLIENT4\CLIENT4.OBJ Error: Unresolved external '_do_disconnect' referenced from D:\PROG\MYSQL\CLIENT4\CLIENT4.OBJ I took the client4.c program over to my FreeBSD machine and it compiled and ran without any issues. This is when I decided to try MinGW. The first compile attempt is attached below. The very first error message from MinGW was about line 119 in mysql_com.h, just like with Borland. So I added the "#include <winsock.h>" line to both client4.c and common.c and ended up with the second error list. I have several questions, obviously, the first of which is, "Why does client4.c compile and run under Unix but not under MinGW - and what does winsock.h have to do with this? Something seems to be missing on the Windows system. Winsock.h seems to get me by the compile issue(s) and leaves me with link issue(s). Am I missing some library(ies)? Anyway, it's hard for me to remember that the original objective was to drain the swamp (learn MySQL from a C perspective) when all of these alligators are nipping at my derrier. Anyway, thanks for listening.

If you need to include a winsock header, then maybe you need to link a winsock library. I don't know anything about mysql, but if it's popular try searching more for other people's experience compiling it with gcc. I find about thirty messages on this list that mention mysql in the past year. Looks like you aren't the only one with these problems. There's an archive search at www.mingw.org, and google shows about 25800 hits for 'mysql cygwin'. If something works under *nix, then there's a pretty good chance it'll work with cygwin--which has much code in common with mingw but adds a compatibility layer that might fix your problems. Or maybe someone who has experience with mysql and mingw will step in.... > Anyway, it's hard for me to remember that the original objective was to > drain the swamp (learn MySQL from a C perspective) when all of these > alligators are nipping at my derrier. C is a small language, but a subtle one. I think you've set yourself a difficult task, but good luck. |

Hi There > > Error E2139 c:\progra~1\mysql\include\mysql_com.h 119: Declaration missing ; > > > > I searched the internet and found only one instance of "mysql_com.h" and > > "Declaration missing;" That thread said to: > > > > #include <winsock.h> IIRC MySQL library is built for Microsoft compilers, to link the MySQL dll with a borland compiled program you need to run the Borland import utility to create a .lib file to link with. If you wish to link the MySQL library with Borlands VCL in your program , dont forget to include <windows.h> before your <vcl.h> include ( otherwise the compile process chokes and it chokes with the above message IIRC ). I have never had occasion to build MySQL client programs with MingW , but I am sure that it wouldnt be hard to do so, but I have to confess my knowledge ends with Borland. If you want I can send you a c++ class I use with Borland C++ Builder that allows access to MySQL C API ( basically it just wraps the C API )? I am now wandering off topic so I will now shut up.

Therefore you need to create a MinGW import library for the MySQL DLL. I think this is a fairly ineffective way to learn C/C++, though. Luke |

Greg, thanks again. I'll load up Cygwin and see what happens but I won't be very surprised if it compiles without a hitch ... which will leave me wondering why this code compiles and runs under FreeBSD and Cygwin but not under Windows via C++Builder or MinGW... ...and it was my feeling also that getopt was missing from C++Builder 6. |
