Need help in compiling for openwrt

[gregor-hh]

Hi,
Can someone help me with compiling passh for openwrt? (I never ever compiled something :-) )
And need passh for my micro wrt router (GL-AR750S)
Iam on OpenWrt 18.06.1, r7258-5eb055306f and installed "make" but it can't find "cc command".

Which is the best method for newbies to compile?

Maybe it's pssible that you can create a "compiled release" here??

best regards

I can find some time and help build for you. What's your router's platform/target?

Hi, wow that sound very good, awesome! Thank you very much.
I have this one https://www.gl-inet.com/products/gl-ar750s/ (it's a very nice device by the way)

Architecture Qualcomm Atheros QCA956X ver 1 rev 0
Firmware Version OpenWrt 18.06.1 r7258-5eb055306f / LuCI openwrt-18.06 branch (git-18.196.56128-9112198)
Kernel Version 4.9.120

kindly regards

What's the download URL (like https://downloads.openwrt.org/releases/18.06.2/targets/ramips/mt7620/ ) to the install image for your router? I need to download the SDK from the same location.

[gregor-hh]

Ohhh shit :-(

Hmm its from gl-inet
https://dl.gl-inet.com/firmware/ar750s/

any chance that I can determine via ssh command on which openwrt version it depends?

[clarkwang]

Found it. According to https://openwrt.org/toh/views/toh_fwdownload it should be under https://downloads.openwrt.org/snapshots/targets/ath79/generic/ . Will let you know when it's ready.

[gregor-hh]

Great! Thank you very much.
kindly regards

Try this: passh - ath79/generic (available for only 7 days)

[gregor-hh]

Wow, you are fast :-)

NIce!!!

That works:

root@localhost:~# passh -help
Usage: passh [OPTION]... COMMAND...

  -c <N>          Send at most <N> passwords (0 means infinite. Default: 0)
  -C              Exit if prompted for the <N+1>th password
  -h              Help
  -i              Case insensitive for password prompt matching
  -n              Nohup the child (e.g. used for `ssh -f')
  -p <password>   The password (Default: `password')
  -p env:<var>    Read password from env var
  -p file:<file>  Read password from file
  -P <prompt>     Regexp (BRE) for the password prompt
                  (Default: `[Pp]assword: \{0,1\}$')
  -l <file>       Save data written to the pty
  -L <file>       Save data read from the pty
  -t <timeout>    Timeout waiting for next password prompt
                  (0 means no timeout. Default: 0)
  -T              Exit if timed out waiting for password prompt
  -y              Auto answer `(yes/no)?' questions

Actually I'm using sexpect on my router now. It's more flexible than passh. You can try it if need more features. :)

Hi.
Could you tell me how you have cross-compiled it for openwrt?
When i compile my own stuff i have no problem, but when i try to compile passh:

mips-openwrt-linux-uclibc-gcc -L ~/softwareentwicklung/router/modbus-master-slave/sdk/OpenWrt-SDK-ar71xx-for-Linux-i686-gcc-4.3.3+cs_uClibc-0.9.30.1/staging_dir/toolchain-mips_r2_gcc-4.3.3+cs_uClibc-0.9.30.1/lib passh.c

i get this:
`

I have no idea why it doesnt find ld-uClibc.so.0 ...

Hi Andi,

I'm not directly invoking the cross compile cc command. I made a simple Makefile and run make package/passh/compile (see https://openwrt.org/docs/guide-developer/using_the_sdk ).

The package/passh/Makefile:

PKG_BUILD_DIR := $(BUILD_DIR)/$(PKG_NAME)

include $(INCLUDE_DIR)/package.mk

define Package/passh
    SECTION := utils
    CATEGORY := Utilities
    TITLE := passh
endef

define Package/passh/description
    This is the package description.
endef

# Specify what needs to be done to prepare for building the package.
define Build/Prepare
        mkdir -p $(PKG_BUILD_DIR)
        $(CP) ./src/* $(PKG_BUILD_DIR)/
endef

# Specify where and how to install the program.
define Package/passh/install
        $(INSTALL_DIR) $(1)/bin
        $(INSTALL_BIN) $(PKG_BUILD_DIR)/passh $(1)/bin/
endef

# This line executes the necessary commands to compile our program.
$(eval $(call BuildPackage,passh))

The package/passh/src/Makefile:

passh: passh.o
        $(CC) $(LDFLAGS) passh.o -o passh

passh.o: passh.c
        $(CC) $(CFLAGS) -c passh.c

clean:
        rm *.o passh
