I am trying to develop a toolchain for wllvm (whole program LLVM) on bazel 3.7 following the tutorial (link to the tutorial). A problem I have is I have to pass an environment variable (LLVM_COMPILER) to wllvm. Can you possibly provide more details here or a concrete example? Is it possible to directly configure the environment variable in .bazelrc?
Thanks a lot!
If it is ok to set an environment variable for each Bazel action, then use --action-env flag
# .bazelrc
build --action_env=LLVM_COMPILER=wllvm

I am using Yocto, when i run command env, i could see couple of variables have been set. But when I open up /etc/environment, those variable is not in there.
When i set variable in /etc/environment, for example, proxies, it is not reflected to my system.
How can I know where's the environment variable file?
Thank you.
Yocto environment is set by executing oe-init-build-env script. You can add bitbake variables in local.conf file.
I have a little problem.
I source a script which changes my RedHat environment (PATH, LD_LIBRARY_PATH, etc.i).
When I launch my install with scons, it charges the default Environment from my machine, but not the current that I loaded...
I tried several attempts, but it was not conclusive. Most of the answer on the net are relative to a change on one variable which have to be set in the SConstruct.
How can I tell scons to charge the current Environment, but not the default ?
Thanks in advance !
The SCons way would be to set these environment variables in your SConstruct/SConscripts so that every user would end up with a reproducible build environment.
Take a read of the FAQ for this: http://scons.org/faq.html#Why_doesn.27t_SCons_find_my_compiler.2BAC8-linker.2BAC8-etc..3F_I_can_execute_it_just_fine_from_the_command_line.
SCons does not automatically propagate the external environment used to execute 'scons' to the commands used to build target files. This is so that builds will be guaranteed repeatable regardless of the environment variables set at the time scons is invoked. This also means that if the compiler or other commands that you want to use to build your target files are not in standard system locations, SCons will not find them unless you explicitly set the PATH to include those locations.
Already found the solution after some more search : env = Environment(ENV = os.environ)
I would like to deploy some js files to bintray, reading the instructions on http://docs.travis-ci.com/user/deployment/bintray/ I see that the name of the version is configured in the descriptor file. I would like it to use the git-tag instead. So that to make a release I only need to push a tag without having to modify a configuration file on each release. Is this possible?
You need to use the built-in environment variables. The one that you are looking for is TRAVIS_TAG. The full list is here.
you have to generate the descriptor file as part of your build. There you can check the environment variable using e.g. python or shell.
It looks like this question has been asked many times. I searched but I could not get the answer
I am looking for techniques on how to set environment variables in Windows system using Ant
I have around 10 environment variables that needs to be set before I can start the compile using Ant
I am running on Windows system.
any help would be appreciated
Thank you,

There is no way to set environment variables through Ant.
The property task can only be used for getting the value of an already set environment variable.
You would need to call Ant's exec task and pass the command line (for your operating system) to set the value of an environment variable.
I am currently relearning Ocaml and am in the need of a good editor. There is a new editor from OcamlForge: OCamlEditor http://ocamleditor.forge.ocamlcore.org/. Prerequisite for installation is Lablgtk2.
Installing Lablgtk2 on windows is not straight forward and there is good instruction here: http://wwwfun.kurims.kyoto-u.ac.jp/soft/lsl/install-win32.txt
I have completed the first two steps and in the third step, as warned, it is failing on the native code version. This is where I am left stranded. How do I check to see if the assembler is on my path? What am I missing here?
Please help me move forward from this point.
You have an MSVC installation, right? By default MSVC doesn't add command-line tools (cl - compiler, ml - assembler, link - linker) to the PATH (and needed directories to INCLUDE and LIB). But it provides a shell script to do this - MSVS9\Commnot7\Tools\vsvars32.bat. Copy it somewhere to the PATH so that you can easily call it any time needed. Then, before running ocaml compiler call vsvars32.bat to setup the environment. You can make this environment permanent by looking at changes to %INCLUDE%, %LIB% and %PATH% variables made by this script and adding them manually to environment variables of current user (usual windows gui insanity - My Computer -> Additional -> Environment variables).
