Re: Building Bedrockdb in cygwin

[Jose Isaias Cabrera]

Greetings!

I am trying to build Bedrockdb in cygwin.  Running make gives me this output:

e608313@HOR711318E ~/Bedrock-master
$ make
git submodule init
git submodule update
cd mbedtls && git checkout -q c49b808ae490f03d665df5faae457f613aa31aaf
fatal: reference is not a tree: c49b808ae490f03d665df5faae457f613aa31aaf
make: *** No rule to make target 'mbedtls/library/libmbedcrypto.a', needed by 'libstuff/libstuff.d'.  Stop.

Any thoughts?  I tried getting help from the bedrock group, but their google group has not been updated since 2017.  So, I thought that I would try it here. Any guidance would be appreciated.  Thanks.

I know nothing about Bedrock, but I'd ask what you did before running  
"make."  Did you do ./configure?  Is there perhaps an autogen.sh to  
run?  In applications I've compiled which use git submodules, it's  
often been autogen.sh which actually initialized them, which must be  
done before updating them, and I seem to recall that it's something  
that needs to be done prior to the "git submodule init".

Thanks Jack for the prompt reply. No, there is no configure.

No, no autogen.sh either.

Thanks. This is what the README.md says,

$ cat README.md
# Expensify/Bedrock/
This public repo contains the Bedrock database server.  For more information on what that is, please see http://bedrockdb.com  The directories in this repo include:

* `/` - Contains the main Bedrock source
* `/docs` - Source for the public website (hosted via GitHub Pages): http://bedrockdb.com
* `/libstuff` - A general purpose C++ framework for cross-platform application development
* `/mbedtls` - The mbed TLS from here: https://tls.mbed.org/
* `/plugins` - The various plugins provided "out of the box" to Bedrock
* `/sqlitecluster` - The distributed transaction framework built atop sqlite: http://sqlite.org

So, it looks like the root (c49b808ae490f03d665df5faae457f613aa31aaf) does not exists... Thanks for the quick reply, though.

The submodule might look in the wrong place as clearly it is available here:

This issue is that at that point, the higher level make assumes that  
mbedtls is a git repository.

I don't fully understand the git submodules, but something in the main  
git repository should have the info about where the git submodule's  
upstream repository is.  I'll guess here that you started by unpacking  
a tarball, and not cloning the Bedrock git repository, and that they  
failed to include the main .git folder in the tarball.  You'll probably  
either need to start by a git clone, or have them tell you how to  
manually specify the missing submodule information.

However, in doing a bit of searching, I just found a stackoverflow  
answer which includes "This is the most common problem with submodules.  
The commit that you are on in the outer repository has a reference to a  
commit in the submodule that someone did not push up yet. It's a  
dependency problem. Always push from the inside-out. This is most  
likely not something you did wrong, but someone else that's working in  
the repository. "    This implies that mbedtls does have a .git folder,  
but that particular commit is not yet available.  Try doing a "git  
pull" when in that subdirectory.  Otherwise, wait for a response from  
the Bedrock team.

This is what the Makefile has,

[snip]
# The mbedtls libraries are all built the same way.
mbedtls/library/libmbedcrypto.a mbedtls/library/libmbedtls.a mbedtls/library/libmbedx509.a:
        git submodule init
        git submodule update
        cd mbedtls && git checkout -q c49b808ae490f03d665df5faae457f613aa31aaf
        cd mbedtls && $(MAKE) no_test && touch library/libmbedcrypto.a && touch library/libmbedtls.a && touch library/libmbedx509.a
[snip]

and this is my error I am getting right at that spot:

$ make
git submodule init
git submodule update
cd mbedtls && git checkout -q c49b808ae490f03d665df5faae457f613aa31aaf
fatal: reference is not a tree: c49b808ae490f03d665df5faae457f613aa31aaf
make: *** No rule to make target 'mbedtls/library/libmbedcrypto.a', needed by 'libstuff/libstuff.d'.  Stop.

Question: does it matter that I did a 'git init' before starting this?  Thanks for any help.

Yep, that's what happened.  The reason why was this...

$ git clone https://github.com/Expensify/Bedrock.git
Cloning into 'Bedrock'...
fatal: unable to access 'https://github.com/Expensify/Bedrock.git/': Out of memory

So, I downloaded the tarball and...

Yeah, they are not responding. So, I guess I'll have to figure this one out the hard way...

Yeah, I read that one, amongst other git suggestions.  One of them was doing a 'git init'.

I'll give this a try...

I think that means you.  Do you have enough disk space?

Before doing much else, however, please confirm that that subdirectory  
does have a .git folder.  If so, the git pull should work.  If not, it  
wont.

You are right.  There is no .git folder within mbedtls. Hmmm...

I am not a git guy.  Do I do a 'git init' to get a .git folder created?

Which drive are you trying to build on?  B: 3.9G might well not be  
enough room.  C: and D: seem to have enough space.

The problem is you can't just create a new git repo from thin air.  You  
need to pull it from the mbedtls site.  The Bedrock repository contains  
the bits that tell the git submodule commands how to do that - that's  
what is missing from the tarball.  I suppose you could go to the dir  
one above mbedtls and try cloning that repository, which should then  
have all the pieces Bedrock seems to expect.

I am trying to install it on c: so it has enough information.  I did see this reference [1] on stackoverflow, which is points to a memory problem. I am running a 32 bit instance of cygwin, so, it may not have enough memory for the whole clone process.  I will try tomorrow to reboot and try it without any applications.  This may provide the "memory" needed.  Is there any way to assign more memory to the cygwin terminal through windows?  Thanks for all your help.  I really appreciate it.​

You might want to try installing WSL then follow the Ubuntu instructions to
figure out what the build resource requirements are.
Then use the peflags settings in

after applying the linked MS settings if you are running 32 bit Windows.
If you are running 64 bit Windows, you should run 64 bit Cygwin if you need more
than 4GB memory total for maximum heap after rebasing for all exes and dlls.

This is a good advice.  I tried running this command,

$ peflags --cygwin-heap git.exe
git.exe: skipped because nonexistent

how do I add more memory to git.exe using peflags?  I read the site you mentioned above, and it's not very clear as to how it can be done.  There is actually a mistake in the documentation: the third sentence reads,

"In some cases, this problem can be solved by changing a field in the file header which is utilized by Cygwin since to keep the initial size of the application heap."

I think the word "since" after Cygwin, is not needed. Thanks.

Patch years ago to one doc source line removed "version 1.7.10" but left "since"
on the previous doc source line.

Re: Building Bedrockdb in cygwin

[Jose Isaias Cabrera]

So, finally, I was able to to through the git problem: I needed to set the correct proxy syntax, here it is in case someone ever gets a git out of memory error:

git config --global http.proxy http://proxyuser:proxypwd@proxy.server.com:8080

and

change proxyuser to your proxy user
change proxypwd to your proxy password
change proxy.server.com to the URL of your proxy server
change 8080 to the proxy port configured on your proxy server

However, having jumped that huddle, I encountered a new one, which is probably easier to deal with. The make command does a lot of work, but once it's going to start compiling, I get,

make: g++-6: Command not found
make: *** No rule to make target 'libstuff/libstuff.d', needed by '.build/libstuff/libstuff.d'.  Stop.

So, it appears that I need something called g++-6. I have both gcc and g++

$ ls /usr/bin/g++*
/usr/bin/g++.exe*

So, the question is, what is g++-6, and how to I get it?  I tried to find it with cygwin's setup, but it's not on the distro.  I tried to duckduckgo it, but I didn't get anything useful.  Thoughts?  Thanks

g++-6 is version 6 of the C++ compiler in the GNU Compiler Collection.

Cygwin's gcc and g++ is version 7.4.0:
$ g++.exe -dumpversion
7.4.0

Bedrockdb's makefile begins with:

# Set the compiler, if it's not set by the environment.
ifndef GXX
         GXX = g++-6
endif

ifndef CC
         CC = gcc-6
endif

so the C++ compiler (GXX) is set to g++-6 unless GXX is set explicitly.


You need to run make like this:

CC=gcc GXX=g++ make <whatever arguments you gave to make, if any>

This will force make to use g++ instead of g++-6

Hope this helps,

Csaba

Thanks, this works, but I think I have other dependencies.  This is what I now have,

$ CC=gcc GXX=g++ make
g++ -g -std=c++14 -fpic -O2 -Wall -Werror -Wformat-security -DGIT_REVISION=ce62c88 -I/home/e608313/Bedrock -I/home/e608313/Bedrock/mbedtls/include -MMD -MF libstuff/libstuff.d -MT libstuff/libstuff.h.gch -c libstuff/libstuff.h
libstuff/libstuff.h:7:10: fatal error: execinfo.h: No such file or directory
 #include <execinfo.h> // for backtrace
          ^~~~~~~~~~~~
compilation terminated.
make: *** No rule to make target 'libstuff/libstuff.d', needed by '.build/libstuff/libstuff.d'.  Stop.

I did a search on the web on both duckduckgo and google and there is nothing out there.  I can tell you that to build bedrockdb in Ubuntu, you need these steps,

==begin
# Clone out this repo:
git clone https://github.com/Expensify/Bedrock.git

# Install some dependencies
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-6 g++-6 libpcre++-dev zlib1g-dev

# Build it
cd Bedrock
make
==end

I went and grabbed all the libpcre* and zlib* from cygwin, but I don't know what toolchain is in cygwin.  So, libstuff must be a special file that I don't seem to find on the web.  However, there are some execinfo.h hits, but for different applications.  Any thoughts?  I will go back to the bedrockdb team and see what they say.  Thanks for any input.
