env.PrependENVPath/AppendENVPath doesnt' work as expected: - path

I installed nodejs and hope to add bin directory for scons:
import os
env=Environment()
env.PrependENVPath('PATH','/home/my/node/bin')
print "PATH is", env.subst('$PATH')
Running scons, it prints:
PATH is
Well no value is printed. Why is that?

Change to the following to see the results of your PrependEnvPath
import os
env=Environment()
env.PrependENVPath('PATH','/home/my/node/bin')
print("PATH is", env['ENV']['$PATH'])
Yields:
$ scons.py
scons: Reading SConscript files ...
PATH is:/home/my/node/bin:/opt/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/MacGPG2/bin
scons: done reading SConscript files.

"Error: LaTeX failed to compile" output when using TinyTex; error running pdflatex (exit code 1)

I'm using an R Sweave doc and trying to compile a pdf from RStudio using TinyTex. Let's assume my Sweave file is titled "Example.Rnw" and my file path to the .tex output is "Path/Example.tex." After hitting "Compile PDF" in my Sweave doc, I get the following error:
[1] "Example.tex"
Compiling document with tinytex ... Error: LaTeX failed to compile /Path/Example.tex. See https://yihui.org/tinytex/r/#debugging for debugging tips.
Execution halted
failed
Error running /usr/local/bin/pdflatex (exit code 1)
When I copy and paste the resulting .tex file into Overleaf, the pdf looks fine. My guess is there's some issue with pdflatex and TinyTex, but I'm not sure what. After a few hours I'm still stumped. Any advice for how to compile this pdf? I've already updated and reinstalled TinyTex, and set my PATH to the TinyTex distribution folder. Thanks in advance.

Tensorflow tfcompile: fail at step 2

I follow https://www.tensorflow.org/xla/tfcompile, and fail at step 2.
What's wrong?
cschen
~/git/tensorflow$ bazel build --config=opt //t1:test_graph_tfmatmul
... INFO: Found applicable config definition build:download_clang in
file /home/cschen/git/tensorflow/.bazelrc:
--crosstool_top=#local_config_download_clang//:toolchain --define=using_clang=true --action_env TF_DOWNLOAD_CLANG=1 INFO: Found applicable config definition build:opt in file

ERROR: Analysis of target '//t1:test_graph_tfmatmul' failed; build
aborted: no such package 'tools/target_cpu': BUILD file not found on
package path ...
I copy to t1/BUILD from step 2 as follows,
~/git/tensorflow$ cat t1/BUILD
load("//tensorflow/compiler/aot:tfcompile.bzl", "tf_library") ...
The expected result is to generate header file test_graph_tfmatmul.h.
I don't know which version you are using, but on TF1.14, if you git grep tools/target_cpu, you will see one result in the file tensorflow/compiler/aot/tfcompile.bzl.
In the directory tools, there is nothing reminiscent of target_cpu, so I think it must be a bug with the tfcompile.bzl. The problem disappears for me when I comment out the line referencing tools/target_cpu.

build_iphone.sh: line 52: /Users/.../pocketsphinx-master/configure: No such file or directory

I'm on macOS Mojave in terminal, and I'm getting an error that says no such file or directory for the directory ".../pocketsphinx-master/configure" when I run build_iphone.sh, which I got from this repository: cmusphinx/pocketsphinx-ios-demo.
The instructions for pocketsphinx found at this repository -- cmusphinx/pocketsphinx gives these instructions to use pocketsphinx with Xcode. Here's part of what it says, which I don't understand:
Pocketsphinx uses the standard unix autogen system, you can build pocketsphinx with automake given you already built sphinxbase You just need to pass correct configure arguments, set compiler path, set sysroot and other options. After you build the code you need to import dylib file into your project and you also need to configure includes for your project to find sphinxbase headers.
Here is what my terminal on my Mac mini looks like:
Daniels-Mac-mini:pocketsphinx-master shinehah$ sh build_iphone.sh
building arm64...
build_iphone.sh: line 52: /Users/shinehah/cmusphinx/pocketsphinx-master/configure: No such file or directory
I created that directory, but I still get the same error message. What do I need to put in that directory?
In build_iphone.sh, line 52, it says:
--host="${HOST_TYPE}" \
Here is the code segment it is from:
$CWD/configure
--host="${HOST_TYPE}" // line 52
--prefix="$DEST/$ARCH"
--without-lapack
--without-python
--with-sphinxbase="$SPHINXBASE_DIR"

Quantlib with boost for iOS build on xcode 4.6

I'm trying to build quantlib for xcode 4.6.
The project of concern is this one: https://github.com/philipbarnes/quantlib-on-iOS
This quantlib project relies on this boost project: https://gitorious.org/boostoniphone/boostoniphone
My problem is I cannot get this boost to build, but I can get another version to build on github also by Pete.
One of the steps in building quantlib for iOS asks to set the boost dir. I tried to adjust this to no avail. 
This means I have a dir 'boostoniphone-huuskpes-boostoniphone' - which does not build and was said to be the version to use with the quantlib on iPhone project,
and the dir 'boostoniphone-master' which did build - it has a different build structure with folders and maybe setting the $BOOSTDIR variable in the quantlib project isn't so simple.
These outputs from the console have been shorted for more comfortable reading
My gitorious boost output says:
3 warnings generated.

as the other boost project works for me it, I try to link it into the buildql.sh script as a boost ref, but I get:

A pointer to how to make frameworks may also be a solution? But I think getting the quantlib for iOS project to work is the real solution.
Coming back to the BOOST variable, in the buildql.sh file, changes such as the following have been made:
#: ${BOOST_HOME:=$HOME/workspace/huuskpes-boostoniphone}
: ${BOOST_HOME:=$HOME/workspace/boostoniphone-master/}
: ${BOOST_SRC:=$BOOST_HOME/src/boost_1_51_0}
The following were also altered to attempt to fit the 'boostoniphone-master'
: ${SRCDIR:=`pwd`/src}
: ${BUILDDIR:=`pwd`/build}
: ${PREFIXDIR:=`pwd`/prefix}
: ${FRAMEWORKDIR:=`pwd`/framework}
Thanks for any hints, potential solutions.

Aborted: Lipo failed
Rather than go into all the script details the following is the solution:
Set the paths carefully, that means, try not to have spaces or have data on external drive (although you can)
Set the parameters for the ARM chip, simulator and the iOS version installed very very carefully!
All in all that should be the most of it.

scons: source directory does not get copied into build directory

Part of my build process is to create a tar file of an input directory, located at src/bundle/bundle. In src/bundle/SConscript:
Import('*')
bundleDir = Dir("bundle")
jsontar = Command("bundle.tar", bundleDir,
"/home/dbender/bin/mkvgconf $SOURCE $TARGET")
in my SConstruct:
SConscript(Split('src/bundle/SConscript'),
exports='bin_env lib_env', build_dir='tmp/bundle')
When attempting to build:
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
/home/dbender/bin/mkvgconf tmp/bundle/bundle tmp/bundle/bundle.tar
Input directory tmp/bundle/bundle not found!
scons: *** [tmp/bundle/bundle.tar] Error 1
scons: building terminated because of errors.
Clearly scons is not copying the src/bundle/bundle to tmp/bundle/bundle, but I am stumped as to why.
Footnotes:
Using absolute pathname for mkvgconf is bad practice but just intermediate until I have this problem solved.
SCons doesn't know anything about the contents of your input src/bundle/bundle - only the program mkvgconf knows what it does with that directory.
One solution is to add an explicit dependency in the SConscript:
import os
Depends('bundle.tar', Glob(str(bundleDir) + os.path.sep + '*'))
That also means that when you update the contents of the bundle directory, the mkvgconf script will be rerun.
PS. you might want to change the build_dir argument name to variant_dir, as the former is deprecated in favor of the latter in recent SCons releases.
