c++ und mysql

[BLUESCREEN3D]

Ich habe mir von http://www.mysql.com/downloads/api-mysql++.html MySQL++ runtergeladen (die "RPM for Red Hat 8.0 with gcc 3.2") und installiert.
Jetzt will ich das Beispielprogramm von http://www.mysql.com/documentation/mysql++/4_Tutorial.html kompilieren, aber ich kriege das irgendwie nicht hin...

# locate sqlplus.hh
/usr/include/sqlplus/sqlplus.hh



wie mache ich g++ jetzt klar wo die datei ist?

[arthur]

Ändere doch einfach in deinem Testprogram


#include <sqlplus.hh>

nach


#include <sqlplus/sqlplus.hh>

das müsste helfen.
Alternativ kannst du mit der -I Option dem
compiler sagen wo er nach includes suchen kann:


g++ -o simple1.out simple1.cc -I /usr/include/sqlplus/

Nachdem da ein Makefile ist, würde ich
#> make
vorschlagen :)

bei g++ -o simple1.out simple1.cc -I /usr/include/sqlplus/ kriege ich ganz genau 1534 zeilen fehlermeldungen! ******** :mad:

sowas passiert mir irgendwie immer, wenn ich beispielprogramme kompilieren will

wahrscheinlich mache ich irgendwas grundlegendes falsch - also mal der anfang der fehlermeldungen:

btw: make hilft auch nicht

../depcomp: ../depcomp: Datei oder Verzeichnis nicht gefunden
make: *** [resetdb.o] Fehler 127

ist das jetzt fehler nr. 127 oder bedeutet das, dass 127 fehler aufgetreten sind?

[arthur]

das makefile hab ich übersehen ;)
aber ich hab mir mal kurz das packet angeschaut und da ist doch
im hauptverzeichnis ein build.sh, der eigentlich alles bauen sollte.

[BLUESCREEN3D]

# updatedb
# locate build.sh
#

hmm... die datei gibt es nicht...

was genau hast du dir runtergeladen? auch die rpm? und in welchem verzeichnis sollte die datei dann sein?

[arthur]

ich hatte die source distribution gezogen (war halt der erste link;))
und dort ist noch das ganze build system dabei.
also versuch es vielleicht damit, oder du machst per hand weiter
und zeigst ihm halt was er zum kompilieren braucht d.h. als nächstes
>locate mysql.h
/usr/include/xxx/yyyy
>g++ -o simple1.out simple1.cc -I /usr/include/sqlplus/ -I /usr/include/xxx/yyyy

jetzt weiss ich nicht mehr weiter...

(sind das mit dem /tmp/bla... alles nur warnungen oder fehler?)

[arthur]

sieht doch gut aus ;)
kompilieren tut es doch schon, es happert jetzt nur noch beim
linken, er findet nicht die libsqlplus bibliothek.

>locate libsqlplus
...
/usr/lib/xxx/yyy/libsqlplus.so
...
>g++ ....... -L /usr/lib/xxx/yyy -lsqlplus
das sollte dann genügen (hoffe ich doch)

Das ist eine Warning.
Die Datei resiter1.hh inkludiert einen alten C++ Header.
iterator.h statt iterator

Diese Sachen sind Fehlermeldungen des Linkers.
Hier fehlt offensichtlich unter anderem die ganze MysqlConnection Klasse.

Wenn du die Datei simple.cc nur Compilieren willst, musst du den -c switch verwenden.
Beim Linken zur Applikation musst du dann alle Objectfiles angeben.

edit:
jo, funzt gut :D
ich musste zwar die db auf die das proggi zugreifen wollte von hand erstellen und darin eine tabelle erstellen weil das resetdb-script von anfang an nicht funzte aber das passt schon... das schwierigste ist eben das compilieren ^^

jetzt die nächste frage: wenn ich das auf meinem system kompiliere, aber dann versuche das fertige proggi auf nem anderen rechner zu starten, dann kriege ich folgenden fehler:
error while loading shared libraries: libsqlplus.so.1: cannot open shared object file: No such file or directory

jetzt muss ich wohl auf dem rechner auch das komplette mysql++-paket installieren, oder gibt es eine möglichkeit diese libsqlplus.so.1 irgendwie mit einzukompilieren?

[anda_skoa]

Du kannst die Lib statisch linken.
Dazu musst du vor -lsqlplus noch die Option -static angeben.

Statisches Linken halte ich allerdings für eine Unart.

Ciao,
_

[arthur]

versuch mal mit:
# g++ -o simple1.out simple1.cc -I /usr/include/sqlplus/
-I /usr/include/mysql/ /usr/lib/libsqlplus.a
oder mit -static ;)
damit verlinkst du die benötigten teile statisch mit deinem program,
es wird dann entsprechend grösser.
gruss
Arthur

Vielleicht ein bißchen spät gefragt, aber woher bekomme ich die sqlplus.hh?
Habe die Mysqlc++ api installiert, aber der header ist net dabei....

Thx.

Wenn ich dir einen Rat geben darf: Benutze nicht das C++ api welches Mysql direkt anbietet. Das ist total veraltet und gravierend fehlerhaft. Benutze entweder das api von mysqlcppapi.sourceforge.net oder gleich OTL von otl.sourceforge.net. Letzeres habe ich zwar selber noch nicht benutzt, aber es macht zumindest der Doku auf der Seite nach einen guten Eindruck.
