Hey all,
A number of specs use something like:
numprocs=`cat /proc/cpuinfo | grep processor | wc | cut -c7`
But on some systems this is a little problematic... For example, the
output of `cat /proc/cpuinfo` on my machine gives:
processor : 0
vendor_id : AuthenticAMD
cpu family : 5
model : 8
model name : AMD-K6(tm) 3D processor
stepping : 12
cpu MHz : 451.010801
fdiv_bug : no
hlt_bug : no
sep_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 1
wp : yes
flags : fpu vme de pse tsc msr mce cx8 sep mtrr pge mmx 3dnow
bogomips : 901.12
Note that there are two lines containing the word "processor" so the
build will run make -j2. Noticed this recently with the gcc source
package. A better way would be to use:
numprocs=`cat /proc/cpuinfo | grep ^processor | wc | cut -c7`
Which will ensure that "processor" is found at the beginning of the line
only.
