Zylla Posted April 7, 2017 Share Posted April 7, 2017 (edited) You don't need high privileges to use gcc, or any part of the SDK. (You can run it as root, but it's not adviced.) IF the PATH variable is setup correctly, you should be able to find "mips-openwrt-linux-uclibc-gcc" When you issue a command in the terminal it looks through all the folders in the PATH variable to find the file you are trying to execute. The reason we're adding the toolchain/bin directory to PATH is so that you can launch the "mips-openwrt-linux-uclibc-gcc" command in that terminal session. (That file is located within the toolchain/bin directory) If you add the "export PATH" and "export STAGING_DIR" command to ~/.bashrc you will get persistence for you user, and won't need to execute them every time you start a new terminal session.

digip Posted April 7, 2017 Share Posted April 7, 2017 1 hour ago, kerravon said: usin sudo didnt make a difference I was just curious if it was a perms issue and command only available to root, but seems not the case. This is why I said to use the whole path the the program you are starting before adding the rest of the switches and paths. You should be able to change directory to the executable and start it with ./somecommand -some blag blah blah. Make sure the file is executable and not read only as well.

digip Posted April 10, 2017 Share Posted April 10, 2017 type: updatedb locate mips-openwrt-linux-uclibc-gcc Then cd to that path. Then ./mips-openwrt-linux-uclibc-gcc test.c -o test If still not found, I don't know other than it needs to be set to executable(chmod +x), or its not installed properly. Make sure mips-openwrt-linux-uclibc-gcc is an executable file, and not a directory. If there are specific switches needed(I recall Zylla may have mentioned this, if not then ok) make sure to add them to compile for the device, ie: m32 when compileing for 32bit systems on a 64bit system(does not necessarily apply here, just giving as example) Quote Link to comment Share on other sites More sharing options...
Zylla Posted April 11, 2017 Share Posted April 11, 2017 Try doing exactly this below, and report back the output you're getting. cd /home/user/OpenWrt-SDK-15.05-ar71xx-generic_gcc-4.8-linaro_uClibc-0.9.33.2.Linux-x86_64/staging_dir/toolchain-mips_34kc_gcc-4.8-linaro_uClibc-0.9.33.2/bin/ ./mips-openwrt-linux-uclibc-gcc test.c -o test If it manages to find the command "mips-openwrt-linux-uclibc-gcc" after doing this, you are having issues with your environment variables somehow not working.

Zylla Posted April 11, 2017 Share Posted April 11, 2017 "Cannot execute binary file: exec format error" That error message is typical if you are trying to execute a binary file compiled for another cpu-architecture. For example when trying to run 64-bit binaries on a x86 operating-system. What architecture-type are your Ubuntu installation? That SDK is for 64-bit.

kleo Posted April 11, 2017 Share Posted April 11, 2017 How about reset everything, and follow a step-by-step setup procedure for everything required for the OpenWrt SDK. We'll just follow through after that. Quote Link to comment Share on other sites More sharing options...
kerravon Posted April 11, 2017 Author Share Posted April 11, 2017 OK, will build new VM tonight, then go through the installation steps above by zylla see where we get from there and I report progress here. cheers Quote Link to comment Share on other sites More sharing options...
kerravon Posted April 12, 2017 Author Share Posted April 12, 2017 interesting problem now, I have install a 64 bit debian vm, downloaded the chaos_calmer toolchain as per zylla's instructions. Copied the export paths only changing user name to mine, , it wont try to compile unless I use the sudo command i.e sudo ./mips-openwrt-linux-uclibc-gcc test.c -o test it then comes up with 3 messages all saying mips-openwrt-linux-uclibc-gcc: warning: enviroment variable 'STAGING_DIR' not defined re applying the staging_dir export command an opening a fresh terminal makes no difference. Can upload the VM to my dropbox if you want to look at it. Quote Link to comment Share on other sites More sharing options...
digip Posted April 12, 2017 Share Posted April 12, 2017 Can you export your $PATH with the addition of the required path for the staging_dir to it? That might help. Quote Link to comment Share on other sites More sharing options...
