Solved UNDEFINED REFERENCES ERROR while adding DCMTK Libs in QT project..

[ashajg]

Hi guys

I have compiled DCMTK source code for Android platform using ndk-r15c, API LEVEL 24
When i am trying to add compiled libs to my qt project I am getting these errors:

C:\Ashish\dcmtk-3.6.3\dcmnet\libsrc\dul.cc:383: error: undefined reference to 'signal'
vrscanl.c:5453: error: undefined reference to 'stdin'

C:\Ashish\dcmtk-3.6.3\ofstd\libsrc\ofuuid.cc:62: error: undefined reference to 'rand'
collect2.exe:-1: error: error: ld returned 1 exit status

How can I solve these issues?

to add compiled libs to my qt project

please describe:

• where in your Qt project folder structure you're placing your libs for Android
• contents of your .pro file

just in case, have you following these instructions to build DCMTK for Android?

Hi sir

I am keeping my lib and include folder where my project(.pro) file is present.

And added these files by using this in my pro file:

INCLUDEPATH += "C:/Ashish/TestApplications/TestDcmtkQT/TestDcmtkQT/include"
LIBS += -L"$$PWD/lib/" -li2d -ldcmtls -ldcmnet -ldcmdata -loflog -lofstd

And I followed those instructions...

when I look at the issue, they are all coming from DCMTK libs. So this is nothing do with Qt. Are you able to run any simple program on android using the DCMTK libraries ?

Hi sir

I am unable to run program, I added these libs in my QT project and got those errors.

[dheerendra]

So qt has no role to play here. You should be able to compile some small example just using dcmtk library. Check whether you still get the issue.

@dheerendra

Ok sir

This problem is solved by:

1. not setting ANDROID_TOOLCHAIN_NAME in cmake
2. by compiling source code in RELEASE mode.
