meson doesn't find binary dependency - meson-build

I compiled wayland from source code with this command
meson --buildtype=release -D prefix=$HOME/mylib -D documentation=false
then installed it with ninja. Now in $HOME/mylib I have this structure:
total 24K
drwxr-xr-x 6 myuser myuser 4.0K Dec 3 19:52 .
drwxr-xr-x 16 myuser myuser 4.0K Dec 4 17:41 ..
drwxr-xr-x 2 root root 4.0K Dec 3 19:52 bin
drwxr-xr-x 2 root root 4.0K Dec 3 19:52 include
drwxr-xr-x 3 root root 4.0K Dec 3 19:52 lib
drwxr-xr-x 4 root root 4.0K Dec 3 19:52 share
Inside bin folder I have wayland-scanner and when I run this command
wayland-scanner -v
I got this output:
wayland-scanner 1.21.90
Now when I build other source code with meson that has wayland-scanner as dependency I got this error:
../tests/meson.build:2:0: ERROR: Invalid version of dependency, need 'wayland-scanner' ['>=1.20.0'] found '1.18.0'.
This is related to another wayland-scanner that is placed here:
/usr/bin/wayland-scanner
with version 1.18.0. The command
echo $PATH
reply with this output:
/home/myuser/mylib/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games
Why meson doesn't find the updated version of wayland-scanner? Using PKG_CONFIG_PATH doesn't work, same error as above

Hi don't know the wayland package, but from description
I could think that /usr/bin/wayland-scanner is a link to the old installation,
Try to look in your environment for the wayland-scanner scanner binary to check if there is some link do not updated to the new installation.

IntelliJ claims to build but jar files are not touched

I have a java project that builds correctly using mvn
># mvn package
[ok]
># ls -il target/app.java target/app/ap.jar target/docker-app/app.jar
4239421 -rw-r--r-- 1 me domain users 25305467 Apr 27 08:55 target/docker-app/app.jar
4239422 -rw-r--r-- 1 me domain users 25305467 Apr 27 08:55 target/app/app.jar
4239416 -rw-r--r-- 1 me domain users 25305467 Apr 27 08:55 target/app.jar
change sources, build it again and the mtimes change
># mvn package
[ok]
># ls -il target/app.java target/app/ap.jar target/docker-app/app.jar
4239421 -rw-r--r-- 1 me domain users 25305467 Apr 27 08:56 target/docker-app/app.jar
4239422 -rw-r--r-- 1 me domain users 25305467 Apr 27 08:56 target/app/app.jar
4239416 -rw-r--r-- 1 me domain users 25305467 Apr 27 08:56 target/app.jar
as expected. Also if I diff one of these jar files with a copy of an older one, it is different.
I import this project into IntelliJ IDEA and build
Build completed successfully with 3 warnings
however
># ls -il target/app.java target/app/ap.jar target/docker-app/app.jar
4239421 -rw-r--r-- 1 me domain users 25305467 Apr 27 08:56 target/docker-app/app.jar
4239422 -rw-r--r-- 1 me domain users 25305467 Apr 27 08:56 target/app/app.jar
4239416 -rw-r--r-- 1 me domain users 25305467 Apr 27 08:56 target/app.jar
the mtime has NOT changed, and diff reports that the files are identical to copies of the earlier versions.
Why is IDEA not producing new jar files?
Your question is very similar to this one, which I have already answered: intellj IDEA doesnt build jar properly
It helps understanding.
Well looked at the catches. (click zoom)
This uses nvmw local to the project, nothing prevents you from using your nvm version.
Namely intellij provided well, its own build construction system, to create jars without maven. (Even though I personally have not been able to set it up correctly for it to work for starting the application.)
But if you are looking to create a war, I can give you more information to create a war file ...
I use spring boot but the principle remains the same with all simple java projects

Databricks considering files as directory

We are facing an issue on the Databrick filesyste that considers files as directory and we are unable to read files with Pandas. The files exist in the Azure Storage Explorer, and are considered as files as seen here :
We have mounted the storage with oAuth 2.0.
On Databricks,
%sh ls -al '<path_to_files>'
returns the following :
total 1127
drwxrwxrwx 2 root root 4096 Jan 29 09:26 .
drwxrwxrwx 2 root root 4096 Jan 9 13:47 ..
drwxrwxrwx 1 root root 136705 Jan 28 16:35 AAAA_2019-10-01_2019-12-27.csv
drwxrwxrwx 1 root root 183098 Jan 28 16:35 BBBB_2019-10-01_2019-12-27.csv
-rwxrwxrwx 1 root root 313120 Jan 28 16:35 CCCC_2019-10-01_2019-12-27.csv
-rwxrwxrwx 1 root root 212935 Jan 29 09:26 df_cube.csv
-rwxrwxrwx 1 root root 298228 Jan 29 09:26 df_other_cube.csv
​The thing is, the two first csv files are not directories at all. We can download them and read them as csv, but we cannot load them into a Pandas dataframe.
df = pd.read_csv(rootname_source_test + r'AAAA_2019-10-01_2019-12-27.csv',header=0,sep="|",engine='python')
>>> IsADirectoryError: [Errno 21] Is a directory: '/dbfs/mnt/<path>/AAA_2019-10-01_2019-12-27.csv'
They are generated the same way the 3rd csv is generated, and the 3rd on is loadable in pandas. Sometimes they appear as files, sometimes as directories and we are having trouble recreating and solving this consistently.

Any help will be very appreciated.

CMake shared library executable permission missing at install location

Currently I am creating a simple project which will install a utility shared library.
Here's my CMakeLists:
cmake_minimum_required (VERSION 2.6)
project(MathLibs CXX)
add_library (${PROJECT_NAME} SHARED
fact.cpp
fibo.cpp
isPrime.cpp
)
install (TARGETS ${PROJECT_NAME}
RUNTIME DESTINATION ${PROJECT_NAME}/bin
LIBRARY DESTINATION ${PROJECT_NAME}/lib
ARCHIVE DESTINATION ${PROJECT_NAME}/lib)
Since I do not have root privileges I cannot install the shared library in system lib folder. I override the CMAKE_INSTALL_PREFIX to $HOME/apps.
When I build the shared library it had the executable permissions.
Here's the build folder with the shared library:
-rw-rw-r-- 1 ameya ameya 9714 Jun 18 20:02 CMakeCache.txt
drwxrwxr-x 5 ameya ameya 4096 Jun 18 20:02 CMakeFiles
-rw-rw-r-- 1 ameya ameya 2701 Jun 18 20:02 cmake_install.cmake
-rw-rw-r-- 1 ameya ameya 84 Jun 18 20:02 install_manifest.txt
-rwxrwxr-x 1 ameya ameya 6808 Jun 18 20:02 libMathLibs.so
-rw-rw-r-- 1 ameya ameya 7748 Jun 18 20:02 Makefile
drwxrwxr-x 3 ameya ameya 4096 Jun 18 20:02 test
After installing the executable permissions disappears.
Here's the install folder location:
-rw-r--r-- 1 ameya ameya 6808 Jun 18 20:02 libMathLibs.so
What am I missing in the CMakeLists.txt to correct this?
They said that CMake doesn't set execute permissions on installed library because on Linux libraries don't need to be executable.
As for library's permissions in build tree, these are set not by CMake but by the linker.
If you want executable permissions of installed library for some reason, use PERMISSIONS option in install() command.
After looking for more details online I found this referenced in the CMake bugs report.
The handling of shared library on different systems is different I tried using Ubuntu and a Fedora workstation.
On Ubuntu system the system installed shared libraries do not have the executable bit set, but on the Fedora Workstation the same library had the executable bit set.
One can have look at the ${CMAKE_ROOT}/cmake/Modules/Platform/Linux.cmake,
which has the CMAKE_INSTALL_SO_NO_EXE macro defined(sorry for the typo in my earlier reply).

LLVm clang , Error: Invalid file format (bad magic) with -fprofile-instr-use

Flag "-fprofile-instr-use" generates error given below.
This issue occurs even if we build llvm,clang and compiler-rt using cmake or configure.
Please let me know your inputs to resolve this issue

It turns out that step 3 outlined here: http://clang.llvm.org/docs/UsersManual.html#profiling-with-instrumentation
is required even if you only have 1 output file you are using. "Combine profiles from multiple runs and convert the “raw” profile format to the input expected by clang" makes it sound like you should only do this if you have multiple profiles, but you need to do it unconditionally.

libcurl Invalid ELF header in new Arch Install

So I just installed Arch and most things are working fine, but when I try to use pacman or curl, I get the error:
pacman: error while loading shared libraries: /usr/lib/libcurl.so.4: invalid ELF header
Also, I can't seem to run anything pacman-related for now... not even a pacman --help
Not sure if useful, but ls -l /usr/lib | grep libcurl gives:
-rw-r--r-- 1 root root 594016 Jun 22 12:21 libcurl.a
lrwxrwxrwx 1 root root 16 Jun 22 12:21 libcurl.so -> libcurl.so.4.3.0
lrwxrwxrwx 1 root root 16 Jun 22 12:21 libcurl.so.4 -> libcurl.so.4.3.0
-rwxr-xr-x 1 root root 408324 Jun 22 12:21 libcurl.s0.4.3.0
Thanks in advance!
Update: running ./curl-config gives the error, "cannot execute binary file". This makes me wonder if maybe I have a 64 bit version, whilst I'm running Arch i686. What is the best way to handle this?
maybe I have a 64 bit version, whilst I'm running Arch i686
That would do it. Run file ./curl-config. If it says ELF 64-bit LSB executable,... reinstall curl from correct packages.
