Hi all,
I’m trying to build Qt on Solaris 10 and it’s quite a painful operation. I’m using Sun C++ 5.8 (don’t tell me to use something else, it’s on a very controlled environment, and it’s the official compiler).
Doing a configure:
Qt Code: 
  1. ./configure  -no-script \
  2.              -no-scripttools \
  3.              -no-qt3support \
  4.              -no-multimedia \
  5.              -no-phonon \
  6.              -no-webkit \
  7.              -no-svg \
  8.              -no-javascript-jit \
  9.              -no-declarative \
  10.              -no-openvg \
  11.              -no-gtkstyle \
  12.              -xmlpatterns \
  13.              -no-glib \
  14.              -nomake examples \
  15.              -nomake demos
To copy to clipboard, switch view to plain text mode 
seems to work, qmake is built, but carrying on the config script when qmake tries to create project files for config.tests it ends with a segfault.
So I rebuilt qmake with -g flag and debug it. This is the call stack:

To copy to clipboard, switch view to plain text mode 

so the line is
Qt Code: 
  1. if (d->size != other.d->size)
To copy to clipboard, switch view to plain text mode 
The thing is that this->d points to an invalid memory location (0×80000000). Suspecting a QString build issue I logged the stderr after rebuilding qmake. The only warning I have is

Qt Code: 
  1. 5: Warning: d hides QString::d.
To copy to clipboard, switch view to plain text mode 

I have no idea how to fix that any ideas?
Thank you for your help
