| Ok i am trying to compile smuagfuss with a mysql option under cygwin. this is the top part of my make file.
CC = g++
#PROF = -p
#Uncomment to compile in Cygwin
CYGWIN = -DCYGWIN
#repoint these to your mysql directories
MYSQL = -L/usr/local/lib/mysql -I/usr/local/include/mysql/
#Uncomment the line below if you are getting undefined references to dlsym, dlopen, and dlclose.
#Comment it out if you get errors about ldl not being found.
NEED_DL = -ldl
#Some systems need this for dynamic linking to work.
EXPORT_SYMBOLS = -export-dynamic
# Uncomment the two lines below if compiling on a Solaris box
#SOLARIS_FLAG = -Dsun -DSYSV
#SOLARIS_LINK = -lnsl -lsocket
#IMC2 - Comment out to disable IMC2 support
#IMC = 1
W_FLAGS = -Wall -Werror -Wshadow -Wformat-security -Wpointer-arith -Wcast-align -Wredundant-decls
C_FLAGS = -g2 $(W_FLAGS) $(SOLARIS_FLAG) $(PROF) $(EXPORT_SYMBOLS)
L_FLAGS = $(PROF) $(SOLARIS_LINK) -lz $(NEED_DL) $(MYSQL)
#D_FLAGS : For the DNS Slave process. No need in linking all the extra libs for this.
D_FLAGS = -g2 -O $(PROF) $(SOLARIS_LINK)
C_FILES = act_comm.c act_info.c act_move.c act_obj.c act_wiz.c ban.c boards.c \
build.c calendar.c chess.c clans.c color.c comm.c comments.c const.c db.c deity.c \

renumber.c reset.c save.c services.c sha256.c shops.c skills.c special.c tables.c \
track.c update.c variables.c weather.c mysql.c
As you can see i am pointing to the mysql folders, when i compile the mud i get
Compiling o/mysql.o....
/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld: warning: auto-importing has been activated without --enable-auto-import specified on th

This should work unless it involves constant data structures referencing symbols from auto-imported DLLs.o/mysql.o: In function `_Z7open_dbv':

collect2: ld returned 1 exit status
make[1]: *** [smaug] Error 1
make: *** [all] Error 2
Any clues to what could be wrong?
I configured mySQL correctly when i built it or atleast i beleve so. | Top |

| I seem to recall a recent similar problem. This is a linking issue if I read the post correctly.
You need to be cautious where the reference to mysql is in the line that does the linking.
Libraries you are offering to link against need to be specified *before* the files that need them. Putting them at the end of the line won't necessarily work.
eg. Change from:
$(CC) -o smaug.exe $(O_FILES) smaug.exp $(L_FLAGS)
to:
$(CC) -o smaug.exe $(L_FLAGS) $(O_FILES) smaug.exp
(If I am right). Worth trying.

| I made the changes and get the same error. I also through it up on my hosting server just to see (with the proper corrections to the mysql folders) and i get the same errors.
I remember a few years ago i was doing something similar to what i am wanting to do now and had this issue, but i can't remember what i did to fix it.
--Edit
I was doing some more digging around and found i made a mistake.
#repoint these to your mysql directories
MYSQL = -L/usr/lib/mysql -I/usr/include/mysql/
#Uncomment the line below if you are getting undefined references to dlsym, dlopen, and dlclose.
#Comment it out if you get errors about ldl not being found.
NEED_DL = -ldl -lmysqlclient
forgot the mysqlclient call, but now i have a new error which i think is related to my mysql build.

| Where did you get your MySQL libraries from? If you want to compile anything in Cygwin using MySQL you need to build MySQL yourself (using Cygwin). |

| You missed this bit:
ifdef CYGWIN
...
$(CC) -o smaug.exe $(O_FILES) smaug.exp $(L_FLAGS)
Hence it didn't work under Cygwin. |

| Got it. Did some more reading on mysql's site and found this can happen. ran the
mysql_config --libs
and it returned
-L/usr/local/lib/mysql -lmysqlclient -lz -lcrypt -lm
So i added -lz -lcrypt -lm into the mysql part of my make file and it compiled just fine.
