linux - gcc -x java on debian stretch -


the using gnu compiler collection manual gcc version 6.3.0 indicates support language option -x java on page 28 (page 42 of pdf). attempting on debian stretch:

$ gcc -x java helloworld.java gcc: error trying exec 'ecj1': execvp: no such file or directory

installing seems required package:

$ sudo apt-get install ecj1 reading package lists... done ... unpacking ecj1 (3.11.1-1) ... setting ecj1 (3.11.1-1) ... .... reading state information... done

however, same error message when running gcc after this. in fact looking /usr/bin, no executable ecj1 has been installed, , running apt-cache search ecj1 not suggest other package 1 have installed.

$ gcc --version gcc (debian 6.3.0-11) 6.3.0 20170321  $ uname -a linux right 4.8.0-1-amd64 #1 smp debian 4.8.5-1 (2016-10-28) x86_64 gnu/linux

any suggestion else try running?

the gnu compiler java has installed:

$ apt-get install gcj-4.9 gcj-4-9-jdk

use apt-file search packages containing ecj1 file. note apt-cache searches package names/descriptions matching search.

after installation able run using

$ gcj-4-9 helloworld.java

instead of gcc.

even though gcj front-end gcc, gcc didn't work me , complaining classpath not being set. gcc working, require different, more complex command.

if you're compiling class contains main method, use --main option.

$ gcj-4-9 --main=helloworld helloworld.java
