rake: NameError: uninitialized constant Config - rake

I am installing Redmine and I am getting crazy because of a rake problem. In particular, in order to perform a bundle install for the different Ruby's plugins, I have been asked to install xapian-full-alaveteli, v 1.2.9.5.
The problem is that I get the following error:
Building native extensions. This could take a while...
ERROR: Error installing xapian-full-alaveteli:

I've tried editing by hand the rakefile and removing the line that causes troubles, but it magically reappears. The documentation about the use of rake/gem is, imho, at least vague, therefore I am totally stuck -- with a server that was supposed to be in production two days ago...

Summary
Obsolete calls to Config can cause the error. Try changing
Config::CONFIG ====> RbConfig::CONFIG
In detail
Running a Gem's rakefile caused the error: uninitialized constant Config.
Googling suggests Config is obsolete and to replace it with RbConfig. RbConfig is in the latest Ruby though the document is blank and I cannot find a Config in Ruby.
Fixes replace Config with RbConfig: gettalong/kramdown and thoughtbot/cocaine. Which also worked in my case.
Conclusion
Replace Config::CONFIG with RbConfig::CONFIG

Error "Did you compile with -rdynamic?" seen only when application installed using RPM

I have a Vala application that loads modules just gmodule-2.0, when installed through usual make install means everything works correctly. When I build an RPM file and install (on Fedora 27) using dnf install my-app I get a whole bunch of errors like
(my-app:15094): Gtk-WARNING **: Could not find signal handler 'btn_thing_changed_cb'. Did you compile with -rdynamic?
(my-app:15094): Gtk-WARNING **: Could not find signal handler 'adj_thing_value_changed_cb'. Did you compile with -rdynamic?
Even after I add -rdynamic to the build and reinstall I continue to see these errors. Somewhere I read that I need to use gmodule-export-2.0, but the diff on it's pkgconfig and the one for gmodule-2.0 shows that they're exactly the same. Soooo...
The application is written in Vala and built using valac. Also, the UI classes that I have are Gtk template classes which may be an issue, but the fact that it works when I install from source makes me think that it isn't.
This is because the default RPM build will strip the symbols out of executables. You can disable stripping by changing your spec file to include:
%global __os_install_post %{nil}
or:
%global __strip /bin/true

Installing Tensorflow from source

I've been trying to install Tensorflow and get it working over the past few days. Whilst I have managed to install TF and get it working as tested by opening Python in the terminal and typing,
import tensorflow as tf
I have not been successful attempting to retrain Inception v3. I managed to install it from source once by following the instructions laid out here however I am no longer able to do so. When I get to the section 'Create the pip package and install' and go to run bazel build -c opt //tensorflow/tools/pip_package:build_pip_package in the root of my Tensorflow directiory I get the following error.
kieran#kieranUbuntu:~/tensorflow$ bazel build -c opt //tensorflow/tools/pip_package:build_pip_package

This is the same error I ran into when I managed to install it and then attempted retaining the classifier following this tutorial. At the section, bazel build tensorflow/examples/image_retraining:retrain.
I just can't figure out what is going wrong and I have been trying for so long.
I'm using this pip version, # Ubuntu/Linux 64-bit, CPU only, Python 2.7
I think you should search before ask, This link can probably solve your issue.
The issue lied in the incorrect use of ./configure. Whilst it was ran I currently have two versions of python on my computer, both of which are stored in different locations, when running ./configure I pointed it to the wrong python version. After rectifying the issue everything worked correctly.

Building Swift on CentOS

I am building Swift compiler from source on CentOS 6, and am running into a library issue. After fighting with the build script for a while I have got where running ./utils/build-script eventually gives:
+ /home/src/cmake-3.4.1-Linux-x86_64/bin/cmake --build /home/src/swift/build/Ninja-DebugAssert/cmark-linux-x86_64 -- all

/opt/gcc-4.8.2/lib64/libatomic.so.1
/opt/gcc-4.8.2/lib64/libatomic.so.1.0.0
I just don't know how to tell the build system where to look. I have tried the usual CMAKE_LIBRARY_PATH (exporting on the command line - I am not sure if cmake works like the way LD_LIBRARY_PATH, LIBRARY_PATH work) but it can't seem to find it.
I also don't have root on the machine.
I had not tried building from source on CentOS 6 until I saw this question, but I have been able to build Swift 2.2 on CentOS 7.1 and Ubuntu 14.04, with partial success. A few things to think about:
You will need numerous dependencies required to build Swift, and unless
they happen to be already on the system, you will need root access to
install them.
Use -R flag with the build-script to create a release build.
Building in DebugAssert (the default) will require a lot of memory. In my case even 14 GB was not sufficient. A release build
can be done with about 6 GB.
As for your specific problem, it is related to Clang's dependency on GCC-related packages for headers and libraries. See, for example, Fedora 21 with clang, without gcc.
Even if you installed GCC 4.8.2 and adjusted the path to use gcc and g++ from 4.8.2, Clang may still be looking in the old GCC directories for headers and libraries. CMake first tries to compile a C++ test file that includes the header atomic, which does not exist in the old GCC. So, it then tries to link a C test program that uses the library libatomic, which again doesn't exist in the old GCC. You can see this by looking at llvm/cmake/modules/CheckAtomic.cmake mentioned by usr1234567. CMakeError.log and CMakeOutput.log can also provide valuable insight. BTW, when I was building Swift on CentOS 7.1, I didn't run into this problem because GCC 4.8.2 was used by Clang for headers and libraries and the atomic header was found, so the C++ file got compiled. However, had the libatomic check been done, it would have failed, because libatomic.so in the repository-provided 4.8.2 has INPUT ( <name of some non-existent file> ), so trying to link with libatomic errors out.
I'm sure there are various ways of dealing with this issue, but what solved the problem for me was setting the following environment variables, please adjust to your specific setup:
export CPLUS_INCLUDE_PATH=/opt/gcc-4.8.2/include/c++/4.8.2:/opt/gcc-4.8.2/include/c++/4.8.2/x86_64-unknown-linux-gnu
export LIBRARY_PATH=/opt/gcc-4.8.2/lib64:/opt/gcc-4.8.2/lib/gcc/x86_64-unknown-linux-gnu/4.8.2
Also make sure that your 4.8.2 version of libstdc++.so is available to the dynamic linker at runtime. Since you don't have root, do
export LD_LIBRARY_PATH=/opt/gcc-4.8.2/lib64
If you had root, you could use ldconfig.
Before you start building Swift, you may want to try building, using Clang, a simple C program linking it with libatomic (the code doesn't actually have to use any symbols from the lib) and a simple C++ program that includes the <atomic> header. When compiling the C++ program, use the -std=c++11 compiler flag. If the C++ program compiles successfully, then it is not necessary for the libatomic linking test to be successful.
Interestingly, the CMakeOutput.log file still did not report finding GCC 4.8.2 as a candidate GCC installation, but the configuration/build worked well past the error.
Hopefully this helps. Please let us know if you run into something else.
CheckAtomic.cmake seems to be part of LLVM. I found a file at Github and it tries to find '__atomic_fetch_add_4' from libatomic
check_library_exists(atomic __atomic_fetch_add_4 "" HAVE_LIBATOMIC)
This fails for you. Check CMakeFiles/CMakeError.log to get more details why this test failed. Or try this line in a new project.

How to compile CLucene for iOS?

I am trying to compile CLucene for iOS and running into some problems.
Here are the steps I've taken
Modify the CLucene CMakeLists.txt to disable multithreading
Create a "build-ios" directory in the CLucene source directory
Drop the cmake file from this site into the cmake directory http://code.google.com/p/ios-cmake/
run the following command "cmake -DCMAKE_TOOLCHAIN_FILE=./iOS.cmake -GXcode ../"
Here's the output from that command. Can someone help me out with the error?
-- Toolchain using default iOS SDK: /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk
-- Looking for include files CMAKE_HAVE_PTHREAD_H

Thanks for your help!
looks like boost is missing. boost is a required library - check the readme
I know its been long. But just try Cmake with Zlib. Because i am in the process of doing the same thing you did, but waiting till i receive the MAc mini. If you have found the solution please do share because it will be helpful for me and many others. Thank you.

Perl Digest::SHA1 not being imported on OS X Leopard Server

I've been trying to get SVN to connect to Atlassian Crowd for authentication but have been running into issues with OS X Leopard Server (10.5.8) and Perl's Digest::SHA1.
I've installed it from the source (http://metacpan.org/pod/Digest::SHA1) and if I call it directly from a Perl script it works fine, but in my apache logs I get this error:
failed to resolve handler `Apache::CrowdAuth': Can't load '/Library/Perl/5.8.8/darwin-thread-multi-2level/auto/Digest/SHA1/SHA1.bundle' for module Digest::SHA1: dlopen(/Library/Perl/5.8.8/darwin-thread-multi-2level/auto/Digest/SHA1/SHA1.bundle, 1): no suitable image found. Did find:

Unfortunatley there doesn't seem to be any documentation on the error online.
Any ideas?
It seems that there is a mismatch in the compiler architecture triplet between modperl and the Perl executable. The relevant error is really just the "no matching architecture in universal wrapper", which seems to be completely OS X specific.
Are you using MacOS perl? Try building and installing a different perl, it is known that Apple did a terrible job in their perl build.
While looking for links to show Ether, I found this post which may be relevant. It's a bit old, but the mention of Apache caught my eye, since it's part of your problem:
If you've recently migrated from a 32-bit Mac to a 64-bit model, you may have run into problems with some of your Perl modules suddenly throwing up their hands and going "wha?" An AFP548 article points out the likely culprit: CPAN on the Mac compiles all of your modules as Universal 32-bit binaries by default, which tends to disappoint 64-bit applications such as Apache 2.0's mod_perl.
The fix mentioned there is to adjust your ARCHFLAGS variable. The Ars Technica post points to this link for more.
