Hi, guys,
I want to build Linux 2.4.X kernel (head files and its libraries) in order to build a cross compiler GCC. However some errors occurred.
it requests the gcc version currently used on my host machine is less than 4.2.
So I tried gcc 4.0. However while making gcc 4.0 sourc codes, and please see below for details.
Could someone help me with these two errors ? I really want to build a cross-compiler in order to run our 32-bit application on i686 single board computer, which has the following information:
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 11
model name : Mobile Intel(R) Celeron(TM) CPU 650MHz
stepping : 4
cpu MHz : 648.911
cache size : 256 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 mmx fxsr sse
bogomips : 1294.33
I look forward to your help and your response is greatly appreciated.
Best regards,
Dingjun
