INSTALL.py cannot determine gcc version

[izaakm]

During installation, I get this message: "Warning: cannot determine gcc version"

When I search "INSTALL.py", this error message is on line 119.

113try:
114   GCC_VERSION=float(utils.getCommandOutput("gcc --version|grep gcc|awk '{print $NF}' |awk -F \".\" '{print $1\".\"$2}'", False))
115except:
116   try:
117      GCC_VERSION=float(utils.getCommandOutput("gcc --version|grep gcc|awk '{print $3}' |awk -F \".\" '{print $1\".\"$2}'", False))
118   except:
119      print "Warning: cannot determine GCC version"

Running just gcc --version:

Running gcc --version|grep gcc|awk '{print $3}' returns:

I'm not sure how to robustly pull the version number out of this line across various installations.

I don't think there is a universal way to pull out the version. The code has the fallthrough for two cases ($NF, $3) so you can just add one for your version.

GCC_VERSION=0.0
try:
   GCC_VERSION=float(utils.getCommandOutput("gcc --version|grep gcc|awk '{print $NF}' |awk -F \".\" '{print $1\".\"$2}'", False))
except:
   try:
      GCC_VERSION=float(utils.getCommandOutput("gcc --version|grep gcc|awk '{print $3}' |awk -F \".\" '{print $1\".\"$2}'", False))
   except:
      try:
         GCC_VERSION=float(utils.getCommandOutput("gcc --version|grep gcc|awk '{print $4}' |awk -F \".\" '{print $1\".\"$2}'", False))
      except:
         print "Warning: cannot determine GCC version"

That should work on your system. I'll update the code as well.

Solved.
