How to install gcc and g++ 6 on cygwin which are not on the setup.exe

[Jose Isaias Cabrera]

Greetings.

Is there a way an easy way to install gcc-6 and g++-6 on cygwin?  I just uninstalled v7.4.x or whatever was on the setup.  I am trying to build a software and gcc 7.x and g++ 7.x is giving too many compiler errors.  I want to try 6 to see if these errors minimize or go away.  Thanks for the help.

Hi José,

You could perhaps try the Cygwin Time machine :
http://www.crouchingtigerhiddenfruitbat.org/cygwin/timemachine.html

I picked this random link :
http://ctm.crouchingtigerhiddenfruitbat.org/pub/cygwin/circa/2018/10/01/051644/index.html
and it has GCC 6.4

Another option is to download the source and build it yourself.

Yep.  Going with this option.  Seems the most logical one for now.  After running ./configure, got this error,

configure: error: Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC 0.8.0+.

So, now I am building GMP, then MPFR and then MPC.  It's going to be a lot of work, so... :-)  :Let's hope is worth it.  Thanks for your help.

Building GMP, MPFR and MPC seems like overkill. The following packages are 
available for Cygwin:

libgmp-devel 6.1.2
libmpfr-devel 4.0.2
libmpc-devel 1.1.0


BTW, if you're trying to build Bedrockdb, G++ 6 is likely unable to help you. 
The Bedrockdb developers seem to suffer a bit from "all the world is Linux" 
syndrome.

Yep, tried these, and for some reason, when I ran ./configure to build GCC6, it told me that I needed those libraries.  The error message was,

[clip]
checking for the correct version of gmp.h... no
configure: error: Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC 0.8.0+.
[clip]

So, I said, let me just do this, and there will not be any excuse. :-)

Yeah.  Seems like the whole world is thinking like that. :-)  I do have linux boxes at home, but I also have windows.  Thanks for all the help.  I will let you know the outcome.  Already built GMP and MPFR.  Now running 'make' on MPC.  This one should take less time than MPFR.  GMP took a good 3 hours just to run make.  YIKES.  Later.

I've been a Cygwin user for a long time, and I like it, but
another possibility here for you is WSL (Windows Subsystem
for Linux).  It's a pretty easy install, and because it is
done by Microsoft and can reliably use internal interfaces,
there are ways in which it is more Linux-like -- for many
packages you can just do apt-get install and they work.  In
my experience the performance is comparable to Cygwin, maybe
a touch faster (but no where near as fast for heavy forking
as running inside a Virtual Box Ubuntu virtual machine, for
example).  It has its limitations, for sure, but I have found
it helpful for some things.

Thanks for this, Eliot.  Yes, I do have it installed at home, but at work, we're still running Windows 7-42bit systems. ;-)  So, you gotta work with what you gotta work. :-)

Re: How to install gcc and g++ 6 on cygwin which are not on the setup.exe

[Jose Isaias Cabrera]

After more than 8 hours running, building gcc-6.4.0, this error popped up:

In file included from ../.././libjava/jni-libjvm.cc:14:0:
../.././libjava/include/jvm.h:795:3: error: ‘ParkHelper’ does not name a type
   ParkHelper park_helper;

Did a few duckduckgo searches and nothing helpfult was found.  Before I go to the gcc email support, anyone has an idea?  Thanks.

Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada

José, try passing

--enable-languages=c,c++

to configure. Unfortunately, you may need to rm -rf the build
directory and start from scratch.

Yep, that is how I restarted make.  And, by the way, no, there is no need to 'rm -rf ' the directory.  It actually starts and whatever has been built, does not need to be.  So, this is a pretty smart make script.  I am finished and now to start building Bedrockdb. Thanks.

By the way, you're not the only person building Bedrockdb on Cygwin.  Someone 
has posted about 10 fixes in the last few days:

   https://github.com/Expensify/Bedrock/issues

It looks like this person is porting the source code to gcc-7.4.0.

From what I've seen, the errors are independent of the compiler
version. I'm betting on the same errors showing up with g++-6 as with
g++ 7.4 (Cygwin's default compiler).

Thanks, Ken.  Maybe I should go back to my original plan to build with gcc-7.4.0.  These are all the errors that I am getting with gcc 6.4.0, which I just took two days to build:

Re: How to install gcc and g++ 6 on cygwin which are not on the setup.exe

[Jose Isaias Cabrera]

[-- Warning: decoded text below may be mangled, UTF-8 assumed --]

How do I uninstall the installation that I created with the building of gcc6? I did a search on duckduckgo for,

cygwin how to uninstall gcc after building it

and found nothing that could help me.  Right now I have two installs of gcc: v7.4.and v6.4.0.

e608313@HOR711318E ~/gcc/gcc-6.4.0
$ which gcc​
/usr/local/bin/gcc​
​
e608313@HOR711318E ~/gcc/gcc-6.4.0​
$ /usr/bin/gcc --version​
gcc (GCC) 7.4.0​

$ gcc --version​
gcc (GCC) 6.4.0​
Copyright (C) 2017 Free Software Foundation, Inc.​

​
How can I have just v7.4.0?  I tried searching around and nothing.  Any help would be greatly appreciated.  I know I can delete the folder and start all over, but I prefer to keep this one as it was.  Or do you think that I should start from scratch?  Thanks.

josé

Thanks, Ken.  Maybe I should go back to my original plan to build with gcc-7.4.0.  These are all the errors that I am getting with gcc 6.4.0, which I just took two days to build:

If you did "make install" then you can do "make uninstall" unless you 
deleted the build folder.  In that case, you just have to find all the 
pieces and manually delete them.

That is not necessarily a problem. "Hand-built" GCC usually gets
installed into /usr/local (so g++-6 is /usr/local/bin/g++), whereas
the built-in GCC is installed into /usr (so the default GCC 7.4 is
/usr/bin/g++). Unfortunately, whether one or the other is picked
depends on your PATH.

I tend to configure my hand-built GCC with --program-suffix= (e.g. GCC
6 with --program-suffix=-6, so the name of the compiler ends up being
g++-6).

Unfortunately, gcc doesn't support "make uninstall". A workaround is
to make a fake install with "make install DESTDIR=/tmp/usr/local" and
then make a list of all the files under that directory, remove the
"/tmp" and delete the files based on the list, something like

find /tmp/usr/local -type f | perl -pwle 's!/tmp!!' | xargs rm

(disclaimer: untested)

This would leave empty directories behind.

Good to know for the next one. :-(  I should have used this on my run of configure. It would have matched what Bedrockdb make was calling.

I started from scratch. I had a nice cygwin setup with Xfce, which I have to go back and set it back up.  But, that's easier because I know what I am doing here. ;-)  Thanks for all your help.

Thanks, Brian.  I saw that one last night.  Did you see the result?

Closing as won't fix as libgcj (and the java front-end) has been removed from the trunk.

I could not do anything with it.

Ran,

./configure --enable-languages=c,c++

to take out java.  Finished overnight.  Ran 'make test' and there were none.  So now running 'make install' and waiting...  Thanks for your help.

After more than 8 hours running, building gcc-6.4.0, this error popped up:

In file included from ../.././libjava/jni-libjvm.cc:14:0:
../.././libjava/include/jvm.h:795:3: error: ‘ParkHelper’ does not name a type

Did a few duckduckgo searches and nothing helpfult was found.  Before I go to the gcc email support, anyone has an idea?  Thanks.

You seem to be having some difficulty getting an older version of the
compiler running. Perhaps it might be useful to go back to the
beginning and see if there is an alternative solution.

What kind of compiler errors are you getting? Post the gcc command
line and a sample of the errors to see if anyone has suggestions for
resolving them in gcc7.x.

You can use the help option to get more information about a lot of topics.

 | --help={common|optimizers|params|target|warnings|[^]{joined|separate|undocumented}}[,...].
 |                          Display specific types of command line options.

You can use gcc options to determine which version of C the compiler
will compile. There are also options to control which warnings are
generated, and possibly turned into errors by a -Werror option.

Use the info command:

info gcc

and enter the info search command: (CR=press enter)

/-std=CR

to find the relavent section.

That is how I started.  But, when I started to compile Bedrockdb, there were too many compiler errors.  Since the source is gcc-6 compatible, the version I downloaded from cygwin was 7.4.0-01. So, I didn't want to go that way, since the source would have to be changed.

I could try this next, but I would need you to be there. :-)  Just kidding.

Thanks, Doug.  I have installed gcc-6,

e608313@HOR711318E ~/gcc/gcc-6.4.0
$ gcc --version
gcc (GCC) 6.4.0

e608313@HOR711318E ~/gcc/gcc-6.4.0
$ which gcc
/usr/local/bin/gcc

So, now I will start to compile Bedrockdb.  Thanks for all your help, folks.
