link .a lib -textmagic.a

i am having hard time with this..

now the lib is included successifuly
but if i include textmagic.h


//main.cpp
#include "../../MAGIC/include/textmagic.h"


 Textmagic tm;

error : json/json.h: No such file or directory
the error comes from file
MAGIC\include\entity\base.h

#include <json/json.h> // error here

i can correct this include line it should be #include "../jsoncpp/json/json.h"

and if i correct this then same error will be in the next file and so on .. im probably doing somthing wrong

Hi @LeLev,

Please add the following to your .pro file: INCLUDEPATH += ../../MAGIC/include"

And then use this in main.cpp: #include <textmagic.h> then all other includes should be resolved correctly.

@aha_1980 thank you!

LIBS += -L$$PWD/../MAGIC/lib -ltextmagic
INCLUDEPATH += $$PWD/../MAGIC/include

thank you all for reactive support!

I still have the same error

error : json/json.h: No such file or directory

Error comes from file

MAGIC\include\entity\base.h

#include <json/json.h> // error here, there is no dir called json inside entity, the json.h the correcte location is "../jsoncpp/json/json.h"

but if i do #include "../jsoncpp/json/json.h"

i will have lot of erros and this output :

@LeLev This sounds like you are trying to include another library, something json based.

Here's a better way to do this... can you share what you're trying to build? This sounds like it's someone else's project with those 3rd party libs.

If it's an open source project or something you are trying to build share that and we can help you. If it's closed source or your own stuff, give us at least the qmake and a directory listing would be nice (something like find .).

@LeLev said in link .a lib -textmagic.a:

./release/testmagic.o:testmagic.cpp:(.text+0x10): multiple definition of TestMagic::TestMagic(QObject*)' ./release/testmagic.o:testmagic.cpp:(.text+0x10): first defined here ./release/testmagic.o:testmagic.cpp:(.text+0x10): multiple definition of TestMagic::TestMagic(QObject*)'
./release/testmagic.o:testmagic.cpp:(.text+0x10): first defined here

These errors imply that you have linked the testmagic.o object multiple times, both via the .o and the .a would be my guess. Seeing the qmake would help here.

./release/restclient.o:restclient.cpp:(.text+0x1ed): undefined reference to _imp__curl_slist_append' ./release/restclient.o:restclient.cpp:(.text+0x7ec): undefined reference to _imp__curl_easy_init'

These mean you aren't linking to curl. That's yet another dependency you will have to install and link the LIB/INCLUDE paths to it's location.

@LeLev: Why had this topic been deleted? It should have rather been declared as SOLVED.

The answers here may also help other users in future.

@aha_1980 I was stuck, and had no response for 3 days, so i just used another lib...
Thank you @ambershark for your help, i just saw your answers. This is the project i was trying to build :
https://github.com/textmagic/textmagic-rest-cpp

Hi @LeLev

so i just used another lib...

Well, that's also some kind of "solution" ;)

@aha_1980 So i was trying to use text magic c++ lib to send an SMS from my app,
but finnaly i used SMSAPI https://www.smsapi.com/fr, it offers possibility to send a SMS only by doing a post or get request like :

https://api.smsapi.com/sms.do?to=0643566333&message=helloWorld

of cours you have to subscribe/paye (~5cts / SMS)
