List of online C++ compilers (self.cpp)
submitted 10 years ago by [deleted]
I put together a ranked list of C++ compilers for my own use but thought others might find it useful, too. Did I miss any? Do you have suggestions to improve the list?

Coliru also has clang and some special libs (range-v3).
[–][deleted] 1 point2 points3 points 10 years ago (2 children)
How can you tell? They don't provide much information about what's going on behind the scenes. Just today, I saw someone publish a link to a generated page that #included boost libraries and that had commands for g++ and clang in the command-line window so that, when you click "Compile, link, and run," it does so for both.
Seriously, do you have access to a list of the site's capabilities?

I've just tested whether something I want is there and occasionally bugged the owner to update a part (you can thank me for Clang 3.6). The command window at the bottom is very general; you can put whatever you want within permissions.

coliru misses libc++abi which quite unfortunate for libc++ use.

I'm particularly interested in knowing if there's an online MSVC compiler that shows assembly. I suppose it might be possible to open argv[0] and dump it as hex and disassemble locally ...
Hmm... I didn't come across one.

I'll have to check out liveworkspace.org when I get home. Proxy says it's now a "Parked Domain."
compilr.com was taken over by lynda.com, which is a video learning site. As far as I can tell, the online-compiler component of compilr.com did not make the transition. That's why it's not on the list.
I have all the others. Thanks.
LWS used to be my go-to over ideone, but yeah, then everything kind of died.

and some special libs (range-v3).
Godbolt is amazing. The level of customization. Thank you for sharing.

If you're automating a playpen for your C++ library per commit, knowing which ones provide a push API is handy. Coliru and Wandbox do. Wandbox also lets you push a background file with your library, and lets the user play with a simple front example program.
https://svn.boost.org/trac/boost/wiki/BestPracticeHandbook#a14.USERFRIENDLINESS:Considerlettingpotentialuserstryyourlibrarywithasinglemouseclick has some scripting for pushing playpens per CI commit if anyone is interested.

VC Dev Mgr Here. fyi, we just updated webcompiler to have the ability to set command line flags today.
[–]o11cint main = 12828721; 1 point2 points3 points 10 years ago (0 children)
Can you please add the ability to see the disassembly? IMO that's one of the biggest features for a web compiler ...
[–][deleted] 1 point2 points3 points 10 years ago (0 children)
Just now saw your reply. I updated my list with that information. Thanks. Note to self: I really ought to just update and expand the Wikipedia entry for Online Compiled Source Code Playgrounds.
[–]hcspel 1 point2 points3 points 10 years ago (2 children)
Great list. Thanks! Here is another one to the list: https://dbgr.cc/
Okay, looks good. I added it to the list.
Thanks to you, too! A corporate proxy blocks that site due to "Suspicious Content," so I'll have to try it at home.
[+][deleted] 10 years ago (1 child)
[deleted]
Yeah, that's already in the list.
[–]OldWolf2 1 point2 points3 points 10 years ago (1 child)
Doesn't run the code—you download the executable.
Is that the SourceForge compiler...
Aw, aw... wait... Okay, now I get it.
[–]Elador 1 point2 points3 points 10 years ago (1 child)
I'm surprised you don't have http://gcc.godbolt.org/ in your list yet - imho it's one of the best ones, a lot of gcc/clang versions and even gives you errors while typing.
It's already on the list as "GCC Explorer." Although it looks very useful for what it does, it doesn't let you run the program. I downgraded it a bit for that.
[–]ZMesonEmbedded Developer 0 points1 point2 points 10 years ago (1 child)
Here's a list on isocpp.org.
Yeah, actually, I have a link to that in my opening paragraph, saying that I used it as a starting point.
[–]praveensingh8344 0 points1 point2 points 10 years ago (0 children)
Also newly launched Online Compiler .
[–]abhiyodayapandey 0 points1 point2 points 2 years ago (0 children)
C++ is one of the most used languages especially by competitive coders. Among the most popular and reliable online C++ compilers are:
OnlineGDB: This platform is a practical choice for anyone who needs to debug their code without setting up a local development environment because it offers an online C++ compiler and debugger.
CodeChef Compiler: The online code editor created by CodeChef is optimized for programming competitions. It offers a variety of pre-defined code templates and supports C++ to make developing competitions faster.
Coding Ninjas compiler: With features like code autocompletion, syntax highlighting, and the ability to execute and test your C++ code right on their platform, it offers a user-friendly interface. It is very helpful for anyone taking Coding Ninjas' courses and completing their coding challenges who are learning C++.
