When I compile the liibrary with g++ 6.3.1 on CentOS 6.9 the compilation stops at a point:
This is the (IMO) important output:
g++ -o "ide.out" -Wl,-s -L/lib64   -L"/usr/X11R6/lib" -L"/usr/lib" -Wl,-O,2 -Wl,--gc-sections  -Wl,--start-group  \

//lib64/libgthread-2.0.so.0: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
gmake[1]: *** [ide.out] Error 1


Any ideas why this undefined reference to symbol 'g_thread_init' appears? Or did anyone face a similiar error?
EDIT: It seems like the real problem is //lib64/libgthread-2.0.so.0: error adding symbols: DSO missing from command line
Tested with: 11217M, 11287, 11295, 11300
And there weren't any warnings in the rest of the building process.

I added the complete output that is generated if I run sudo make again as a file.

Greetings
Daniel

Googling g_thread_init, I found that it is deprecated. So probably that is the problem and I am wondering if anyone else has the same problem?

EDIT: According to my solution this was not the real problem.

I finally found the problem or at least I did sth and now it compiled all the way through.

It would be nice if one of the admins of U++ could check this solution to solve this problem or if you could tell me what I did wrong if this is no problem of U++.

I did this with the nightly build upp-x11-src-11300 on a CentOS 6.9 machine.
So here is what I did if someone is facing a similiar error:
EDIT: Check out the ways more easier solution in the next reply.

1. Run make until you see this line (the actual compilation will start after this):
DOMAKE INFO: Found make. Compiling...

Use Ctrl+C to abort the compilation.

2. Open the domake file in an editor and remove the following lines:
log_debug_info "Configuring" uppsrc/*Makefile.in *.bm.in "with pkg-config"

if which pkg-config
then

  if [[ "$Flags" = *"NOGTK"* ]]
  then
    requires_libraries="x11 libnotify freetype2"
  else
    requires_libraries="gtk+-2.0 x11 libnotify freetype2"

  fi
  
  library_list=""
  for i in $requires_libraries
  do
    if pkg-config --exists $i
    then
      library_list="$library_list $i"
      log_debug_info "pkg-config: Found library $i"
    else
      log_debug_warning "pkg-config: '$i' not found in $(pkg-config --variable pc_path pkg-config). Do you need to install $i development package?"
    fi
  done

  for i in uppsrc/*Makefile.in
  do
    sed -e "s@-I((INCLUDES))@`pkg-config --cflags-only-I $library_list`@g" -e "s@-L\"((LIBRARIES))\"@`pkg-config --libs-only-L $library_list`@g" "$i" > "${i%.in}"
  done
  
  for i in *.bm.in
  do
    sed -e "s@((INCLUDES))@`pkg-config --cflags-only-I $library_list|sed -e s/-I//g -e \"s/ /;/g\"`@g" -e "s@((LIBRARIES))@`pkg-config --libs-only-L $library_list|sed -e s/-L//g -e \"s/ /;/g\"`@g" "$i" > "${i%.in}"
  done

else
  log_debug_warning "Can't find pkg-config in PATH. Will do configuration without it. Compilation will probably fail"
  log_debug_warning "If compilation fail because of missing include, please install pkg-config before reporting"
  
  for i in uppsrc/*Makefile.in
  do
    sed -e "s@-I((INCLUDES))@@g" -e 's@-L"((LIBRARIES))"@@g' "$i" > "${i%.in}"
  done
  
  for i in *.bm.in
  do
    sed -e "s@((INCLUDES));@@g" -e "s@((LIBRARIES));@@g" "$i" > "${i%.in}"
  done

fi

This won't corrupt the compilation because the pkg-config is already done if you did the first step.
You can also use the attached file instead (the pkg-config part is commented out there)

3. Open uppsrc/Makefile and uppsrc/Makefile.in and add this line:
-lgthread-2.0

I will not attach these files because they are partially generated by the pkg-config.

4. Run make again and it should compile without a problem.

Note: You can run 'make LDFLAGS=-lgthread-2.0' to force the use of gthread-2.0 at link time. It will work without having to edit files or use Ctrl-c.

Here what I found : U++ uses 'g_thread_init(NULL);' in uppsrc/CtrlCore/GtkApp.cpp (line 65).
g_thread_init(); and g_thread_supported(); are deprecated, according to https:// developer.gnome.org/glib/stable/glib-Deprecated-Thread-APIs. html#g-thread-init

There's already a work around in the source code:

#ifdef _MULTITHREADED
#if !GLIB_CHECK_VERSION(2, 32, 0)
    if(!g_thread_supported())
        g_thread_init(NULL);
#endif
        gdk_threads_set_lock_functions(EnterGuiMutex, LeaveGuiMutex);
        gdk_threads_init();
        EnterGuiMutex();
#endif


So, my question is, why does it still compile those lines if your library is greater than 2.32.0?

Intersting. My glib is version 2.28.8 according to yum.
glib2.x86_64           2.28.8-9.el6     @anaconda-CentOS-201703281317.x86_64/6.9
glib2-devel.x86_64     2.28.8-9.el6     @base

Does that mean that the source code should be updated to check on older versions as well?

It already does that. If it's an older version, U++ uses g_thread_supported() and g_thread_init().

In your case, g_thread_init is not part of /lib64/libgthread-2.0.so.0 for an unknown reason.
