c++ und mysql

Beitrag von mitch-geht-ab »

hi.

ich wollte mal fragen, ob irgend jemand schon erfahrungen gemacht hat, um von c++ auf eine mysql db zuzugreifen, ohne odbc treiber oder sonstiges?
(das ganze unter linux/unix)

ich hab jetzt schon die mysql++.h mir besorgt, also mit dem ganzen projekt von mysql.com, aber irgendwie will der beim compilieren nicht so wie er soll!

also es steht auch net viel drin, nur ne main mit einem cout hello world, und halt die mysql++.h includiert, aber kommen tut das alles:

Dem fehlen die Headerdateien unter /usr/include/mysql++ - hast Du die auch runtergeladen und dahin kopiert?
Kann gar nicht sein, ich bin gefürchtet Wald aus, Wald ein.

die dateien bei denen er meckert, die gibt es auch alle!

es sieht halt so aus, als wenn ich fehler im code hätte, aber da steht ja noch garnix!

oder muss man auch ein "using sql irgendwas" schreiben??

Mit aller Vorsicht, da meine Programmiererzeit schon lange vorbei ist:
Etwa in Zeile 4 steht:

Code: Alles auswählen

/usr/include/mysql++/defs.h:34:19: mysql.h: No such file or directory
Daraus würde ich schließen, dass er die Datei mysql.h nicht findet. Ist diese Datei wirklich da bzw. im Suchpfad für die includes ?
Möglicherweise ist mysql.h Bestandteil des DEV-Paketes von mysql. Ist dieses Paket installiert ?

Gruß
Jochen
