[ROOT 5.26 (5.27)] C++ application does not work

ROOT

Hello.
After updating from ROOT 5.22 to 5.26 (5.27) my C++ application does not work any more.
When I try to run it I get the following error message:

dlopen error: /usr/local/lib/root/libGX11.so: undefined symbol: _ZNK9TVirtualX13GetFontAscentEv
Load Error: Failed to load Dynamic link library /usr/local/lib/root/libGX11.so
Error in TCint::AutoLoad: failure loading library libGX11.so for class TGX11
Error in TPluginHandler::SetupCallEnv: class TGX11 not found in plugin GX11
*** Interpreter error recovered ***

Everything worked fine with ROOT 5.22

Thanks for help. :slight_smile:

Hi,

Something must have gone wrong in your installation (and/or setup of LDLIBRARY_PATH), the missing symbol (dlopen error: /usr/local/lib/root/libGX11.so: undefined symbol: _ZNK9TVirtualX13GetFontAscentEv ) is defined in libCore.so which is the essential part of ROOT.

My installation goes like this:

  1. ./configure linuxx8664gcc --prefix=/usr/local --enable-fftw3 --enable-gsl-shared --enable-mathmore --enable-minuit2 --enable-opengl --enable-roofit --enable-soversion --enable-rpath --enable-unuran

  2. make

  3. sudo make install

GSL 1.14 installed, compiled with: ./configure --with-pic

Hi,

Maybe you forgot to recompile your application:[quote]#2 0x00007fc4a135fd21 in TUnixSystem::StackTrace() ()
from /usr/local/lib/root/libCore.so.5.22 [/quote]shows that you are still using 5.22 in part of the loading.

Cheers,
Philippe.

Recompiled, but with no effect…

Hi,

What was your link line for you executable?
What is the result of ls -lart /usr/local/lib/root/libCore*

Compiler parameters:

-I/usr/local/include/root -O3 -g3 -Wall -c -fmessage-length=0 -m64

root-config --cflags --glibs` -lMinuit -lgsl -lgslcblas -lm

Everything works now. I just had to recompile the application.

Thanks for help.
