It is possible to build qt-4.3.3 on sparc-solaris with one small patch. This is necessary because the build system neglects to include --dynamic-list in the linker flags on solaris-g++ Reproducible: Always Steps to Reproduce:
Created attachment 148662 [details, diff] qt-4.3.3-solaris.patch patch for qmake
Created attachment 148663 [details, diff] qt-4.3.3.ebuild.patch patch for the ebuild in the prefix overlay
