GCCNote

Spark builds cleanly on GCC 4.3 series compilers. I use GCC 4.3.3 and it works fine for me. But some users have encountered problems with the 4.4 series. The bundled FLTK library has some incompatibilities with GCC 4.4 series. If your default GCC installation is 4.4.x, you may want to try one of these workarounds:

1. Build with GCC 4.3. This is the suggested method. Install GCC 4.3.x and set these environment variables:
   

export CC=gcc-4.3.x


export CXX=g++-4.3.x


2. If you insist on building with GCC 4.4.x, replace line 70 in ./spark-scheme/libs/fltk/filename_list.cxx with the following code:
   

int n = scandir(d, list, 0, (int(*)(const dirent**,const dirent**))sort);
