complie issue

[ejngnng]

hi,
when I run the gen_misc.sh on ubuntu16.04 32bit, there show this errors:
ninja@ninja-HP-Compaq:~/Project/github/esp_firmware_v2/app$ ./gen_misc.sh
gen_misc.sh version 20150511

Please follow below steps(1-5) to generate specific bin(s):
STEP 1: choose boot version(0=boot_v1.1, 1=boot_v1.2+, 2=none)
enter(0/1/2, default 2):
1
boot mode: new

STEP 2: choose bin generate(0=eagle.flash.bin+eagle.irom0text.bin, 1=user1.bin, 2=user2.bin)
enter (0/1/2, default 0):
2
generate bin: user2.bin

STEP 3: choose spi speed(0=20MHz, 1=26.7MHz, 2=40MHz, 3=80MHz)
enter (0/1/2/3, default 2):

spi speed: 40 MHz

STEP 4: choose spi mode(0=QIO, 1=QOUT, 2=DIO, 3=DOUT)
enter (0/1/2/3, default 0):

spi mode: QIO

STEP 5: choose spi size and map
0= 512KB( 256KB+ 256KB)
2=1024KB( 512KB+ 512KB)
3=2048KB( 512KB+ 512KB)
4=4096KB( 512KB+ 512KB)
5=2048KB(1024KB+1024KB)
6=4096KB(1024KB+1024KB)
enter (0/2/3/4/5/6, default 0):
3
spi size: 2048KB
spi ota map: 512KB + 512KB

start...

is this the right way to complie?

Thanks :)
