PS: i used the --unsafe-perm=true --allow-root cuz I had permission denied error.

Any suggestions, please!

Line 36 is cc --version execution, does this command run if you try it in the terminal?

3

Hello @nazar-pc, no the cc --version commande not found !!

is the cc and gcc not the same ?

cc is usually an alias/symlink for gcc or other compiler (can be clang) that OS configures for you when you install it (on Linux at least).
Try to find instructions for your OS on how to create an alias.

Also as a workaround you can try alias cc=”gcc” in the terminal.

7

do you mean this part in installation:

cc and c++ commands (symlinks) pointing to the corresponding gcc / g++ or clang / clang++ executables.

8

Yes, just Google or DuckDuckGo it

9 
CC --version: CC (GCC) 4.9.2
C++ --version:  C++ (GCC) 4.9.2

type -a CC: CC is /usr/local/bin/CC
type -a C++: C++ is /usr/local/bin/C++

ls -l /usr/local/bin/CC
lrwxrwxrwx 1 root root 18 Sep  7 16:56 /usr/local/bin/CC -> /usr/local/bin/gcc

ls -l /usr/local/bin/g++
lrwxrwxrwx 1 root root 18 Sep  7 16:57 /usr/local/bin/C++ -> /usr/local/bin/g++

am i wrong in what i did?

10

cc and CC are different commands on Linux (by default). You need cc symlink.

11 
cc --version: cc (GCC) 4.9.2
c++ --version:  c++ (GCC) 4.9.2

type -a cc: cc is /usr/local/bin/cc
type -a c++: c++ is /usr/local/bin/c++

ls -l /usr/local/bin/cc
lrwxrwxrwx 1 root root 18 Sep  7 17:11 /usr/local/bin/cc -> /usr/local/bin/gcc

ls -l /usr/local/bin/c++
lrwxrwxrwx 1 root root 18 Sep  7 17:11 /usr/local/bin/c++ -> /usr/local/bin/g++

I removed the symlinks for the CC and C++ and i replace them with cc and c++
is taht right !

12

They are supposed to be in lower case. Anyway, if you install the dev kit of your Linux distribution (as documented in the Installation page) you should be done instead of creating them manually

13

for the configuration i did right now, i tried to install the mediasoup as the documetation said but i got the same error that i posted it above!

so i guess the error was not the cc ?

14

I don’t know what you mean, sorry. BTW you have not even told which Linux distribution you use.

15

Linux Distro:

NAME="CentOS Linux"
VERSION="7 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="7"
PRETTY_NAME="CentOS Linux 7 (Core)"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:centos:centos:7"
HOME_URL="https://www.centos.org/"
BUG_REPORT_URL="https://bugs.centos.org/"

@ibc To let you know:

1- I tried to install mediasoup:

sudo PYTHON=python2 npm install mediasoup@3 --save --unsafe-perm=true --allow-root

2- Error i got:

i thought that was a cc --version line 36 error as @nazar-pc suggested, i create the symlink for the cc as i mentioned above, but i had the same error!

17

Apparently cc is not in $PATH for the process that is running compilation.

18

i changed the server and i worked on another server:

PYTHON=python2 npm install mediasoup@3 --save
  • The installation go normally for this time without any error
  • By the end i got an error that said:
g++: fatal error: Killed signal terminated program cc1plus
compilation terminated.
make[1]: *** [deps/libwebrtc/libwebrtc.target.mk:125: /home/admin/node_modules/mediasoup/worker/out/Release/obj.target/libwebrtc/deps/libwebrtc/libwebrtc/system_wrappers/source/field_trial.o] Error 1
make[1]: Leaving directory '/home/admin/node_modules/mediasoup/worker/out'
make: *** [Makefile:24: default] Error 2
make: Leaving directory '/home/admin/node_modules/mediasoup/worker'

what does this mean !

19

Probably not enough memory in your server. Google is your friend:

https://www.google.com/search?q=fatal+error%3A+Killed+signal+terminated+program+cc1plus

20

IDK really what is the reason for that !!

I created a new droplet and test that again it took a very short time and the mediasoup installed as normal!

it will be my first try on that, hope that will be an easy and great adventure!

@ibc @nazar-pc thank you guys for your time!

#Still the reason not understandable!
