[REQ INFO] How to cross-compile SHC to arm/arm64 ?

[nightmare007]

Hello @neurobin

I tried for hours now, to compile SHC for arm & arm64, but without success.

so far, I only managed to SUCCESFULLY compile SHC for i386 ( see my below method ), then to use it, to create compiled bash-based binaries as arm/arm64 compatible.
This is only HALF the solution, since I need a PC for the bash->bin convertion.
( I wish to use SHC on phones ).

Can you please direct me on how to compile SHC for arm/arm 64 ?

---

P.S - for the internet record....
Thanks to a post by @Thiago Zilli Sarmento I managed to compile my bash script to arm & arm64 ( for android ) !!!! :-)

few notes:

1. for some reason, not "gcc-arm-linux-gnueabihf-gcc" nor
   "gcc-arm-linux-gnueabihf-gcc-6" was willing to compile at all - only
   when I used "gcc-arm-linux-gnueabihf-gcc-4.9" -> it worked (for arm)

2. 'make' didn't work till I installed 'automake'

3. I too get wierd output when I compiled of:
   "strip: Unable to recognise the format of the input file `SCRIPT_NAME'
   shc: never mind"
   just ignor it... no harm exist, AFAIK.

4. NEXT IMPORTANT STEP: what's left is to understand how to cross-compile SHC itself to arm/arm64 so that itself can run on these arch types.

5. here are the nessesary steps on lubuntu 16.04 i368 ( i.e x32 ):

aptitude install crossbuild-essential-armhf crossbuild-essential-arm64 automake gcc-4.9-arm-linux-gnueabihf
git clone https://github.com/neurobin...
cd shc

./configure --prefix=$prefix
make clean
make

---

** to compile script to ARM, run:

---

CC="arm-linux-gnueabihf-gcc-4.9" CFLAGS="-march=armv7-a -static" ./src/shc -r -f SCRIPT_NAME
mv SCRIPT_NAME.x SCRIPT_ARM

---

** to compile script to ARM64 (AARCH64), run:

---

CC="aarch64-linux-gnu-gcc" CFLAGS="-march=armv8-a -static" ./src/shc -r -f SCRIPT_NAME
mv SCRIPT_NAME.x SCRIPT_AARCH64

UPDATE:
I think I managed to compile SHC to arm/arm64...
cd ../shc/src
aarch64-linux-gnu-gcc shc.c -static -o shc_arm64
arm-linux-gnueabihf-gcc-4.9 shc.c -static -o shc_arm

When I transfered the compiled shc to my phone, I do indeed can exec shc, but for some-reason, I can't compile THE SAME script I managed to compile on my pc.
This time I only get *.x.c file and NOT *.x file.... well... i'm close..

maybe gcc is missing on my android phone ?

EDIT:
I also tried to run, without success, the following in SHC sources root folder:
./configure --host=arm-linux-gnueabihf CC=arm-linux-gnueabihf-gcc-4.9 CFLAGS="-march=armv7-a -static -Os" make clean make
I get:

On your android phone, you need both gcc and the shell that will be executing the script, installed.
