CODE::BLOCK, CYGWIN and MySql [SOLVED]

[Hirogens]

Hi,

How to integrate MySQL (libmysql.a or libmysqlclient.a" to "CODE::BLOCK, CYGWIN" ?

all my test don't work....

your going to have to be a bit more specific. What is your OS, C::B version and most importantly what is the actual error your getting.

[Hirogens]

Scuse me,

OS : Seven
C::B version 10.05
CYGWIN (no MINWG)

I have find the library and Include of mysql on http://devpaks.org/
For me MySql 5.0.5

And I have some link error,


undefined reference to `_mysql_init'
undefined reference to `_mysql_real_connect'
undefined reference to `_mysql_error'

libmysql.a is in link line

g++-4.exe --enable-libgomp -lncurses -o Serveur.exe obj/Debug/main.o obj/Debug/Console.o    -lgomp C:/cygwin/lib/libform.a C:/cygwin/lib/libmenu.a C:/cygwin/lib/libpanel.a C:/cygwin/lib/libncurses.a C:/cygwin/lib/mysql/libmysql.a -lmysql

not related to C::B so expect this thread to be locked.

just a warning.

and in regards to mysql it is sometimes hard to get to work with mingw/cygwin (not impossible though) my guess is that the import library is broken.

put this in a bat file

call it reimp.bat

@echo off
for %%A in ("%1") do pexports %%A > tmp.def
for %%A in ("%1") do dlltool --dllname %%A --def tmp.def --output-lib lib%%A.a

make sure you have pexports.exe from mingw now run it in a windows prompt in the directory where libmysql.dll is like this reimp libmysql.dll

now you have a libmysql.a in the same dir move it to mingw/lib and try compiling again.

ofc remove the old import library and make sure you actually link against your new one.

You get pretty much the standard answer: read the FAQ

hint: look in the GCC's manual, what -l and -L does...

Thank you very much, Work perfectly

I have read that, but I don't use MinGW, only CYGWIN.
My code must be 100% compatible with linux.

And I use C::B because I don't want developp by remote on my linux server.

[oBFusCATed]

Hm, why do you think I've said something about MinGW?
The tips I've gave you apply for all compilers out there...

[Hirogens]

Yes sorry,

But i'm found many help topic on C::B/MinGW but not many on C::B/Cygwin .. :cry:


I have nothing against MinGW, but not quite compatible.
and of course, your help was on all compilers

np m8

its pretty general stuff so obfuscated is right to making an import library for gcc using mingw tools will work just as well for cygwin since both use gcc

i use it all the time to get import libraries from stuff i cannot build on mingw like apache.
